83-398: A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth ), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper, or other medium was brushed or rubbed repeatedly to achieve the transfer of ink and accelerated the process. Typically used for texts,

166-461: A color range than dyes. Pigments are solid, opaque particles suspended in ink to provide color. Pigment molecules typically link together in crystalline structures that are 0.1–2 μm in size and comprise 5–30 percent of the ink volume. Qualities such as hue , saturation , and lightness vary depending on the source and type of pigment.Solvent-based inks are widely used for high-speed printing and applications that require quick drying times. And

249-498: A lead -based alloy which suited printing purposes so well that it is still used today. The mass production of metal letters was achieved by his key invention of a special hand mould , the matrix . The Latin alphabet proved to be an enormous advantage in the process because, in contrast to logographic writing systems , it allowed the type-setter to represent any text with a theoretical minimum of only around two dozen different letters. Another factor conducive to printing arose from

332-694: A by-product of fire. Ink was used in Ancient Egypt for writing and drawing on papyrus from at least the 26th century BC. Egyptian red and black inks included iron and ocher as pigments, in addition to phosphate , sulfate , chloride , and carboxylate ions, with lead also used as a drier. The earliest Chinese inks may date to four millennia ago, to the Chinese Neolithic Period . These included plant, animal, and mineral inks, based on such materials as graphite ; these were ground with water and applied with ink brushes . Direct evidence for

415-446: A catalyst to cellulose oxidation. These chemical reactions physically weaken the paper, causing brittleness . Indelible means "un-removable". Some types of indelible ink have a very short shelf life because of the quickly evaporating solvents used. India, Mexico, Indonesia, Malaysia and other developing countries have used indelible ink in the form of electoral stain to prevent electoral fraud . Election ink based on silver nitrate

498-404: A change of ink texture or formation of plaque on the surface of the ink (Reibland & de Groot 1999). Iron gall inks require storage in a stable environment, because fluctuating relative humidity increases the rate that formic acid, acetic acid, and furan derivatives form in the material the ink was used on. Sulfuric acid acts as a catalyst to cellulose hydrolysis, and iron (II) sulfate acts as

581-427: A common pen can be harmful. Though ink does not easily cause death, repeated skin contact or ingestion can cause effects such as severe headaches, skin irritation, or nervous system damage. These effects can be caused by solvents, or by pigment ingredients such as p -Anisidine , which helps create some inks' color and shine. Three main environmental issues with ink are: Some regulatory bodies have set standards for

664-512: A compositor into the desired lines of text. Several lines of text would be arranged at once and were placed in a wooden frame known as a galley . Once the correct number of pages were composed, the galleys would be laid face up in a frame, also known as a forme, which itself is placed onto a flat stone, 'bed,' or 'coffin.' The text is inked using two balls , pads mounted on handles. The balls were made of dog skin leather, because it has no pores, and stuffed with sheep's wool and were inked. This ink

747-455: A dozen European countries. By 1500, printing presses in operation throughout Western Europe had already produced more than 20 million volumes. In the 16th century, with presses spreading further afield, their output rose tenfold to an estimated 150 to 200 million copies. By the mid-17th century, the first printing presses arrived in colonial America in response to the increasing demand for Bibles and other religious literature. The operation of

830-498: A few by hand-copying . Gutenberg's newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities. His two inventions, the hand mould and the movable-type printing press, together drastically reduced the cost of printing books and other documents in Europe, particularly for shorter print runs. From Mainz , the movable-type printing press spread within several decades to over 200 cities in

913-628: A few decades. From a single print shop in Mainz , Germany, printing had spread to no less than around 270 cities in Central, Western and Eastern Europe by the end of the 15th century. As early as 1480, there were printers active in 110 different places in Germany, Italy, France , Spain , the Netherlands , Belgium , Switzerland , England , Bohemia and Poland . From that time on, it is assumed that "the printed book

996-498: A hand press connected to a steam engine ." In April 1811, the first production trial of this model occurred. He produced his machine with assistance from German engineer Andreas Friedrich Bauer . In 1814, Koenig and Bauer sold two of their first models to The Times in London , capable of 1,100 impressions per hour. The first edition so printed was on 28 November 1814. They improved the early model so that it could print on both sides of

1079-533: A major role in rallying support, and opposition, during the lead-up to the English Civil War , and later still the American and French Revolutions through newspapers, pamphlets and bulletins. The advent of the printing press brought with it issues involving censorship and freedom of the press. The invention of mechanical movable type printing led to a huge increase of printing activities across Europe within only

1162-446: A paper mill. However, it was not until a 1439 lawsuit against Gutenberg that an official record existed; witnesses' testimony discussed Gutenberg's types, an inventory of metals (including lead), and his type molds. Having previously worked as a professional goldsmith, Gutenberg made skillful use of the knowledge of metals he had learned as a craftsman. He was the first to make type from an alloy of lead , tin , and antimony , which

1245-401: A polymer to suspend the carbon nanotubes. These inks can be used in inkjet printers and produce electrically conductive patterns. Iron gall inks became prominent in the early 12th century; they were used for centuries and were widely thought to be the best type of ink. However, iron gall ink is corrosive and damages paper over time (Waters 1940). Items containing this ink can become brittle and

1328-479: A press became synonymous with the enterprise of printing and lent its name to a new medium of expression and communication, " the press ". The spread of mechanical movable type printing in Europe in the Renaissance introduced the era of mass communication , which permanently altered the structure of society. The relatively unrestricted circulation of information and (revolutionary) ideas transcended borders, captured

1411-408: A press in its completed form, with tympans attached to the end of the carriage, and with the frisket above the tympans. The tympans, inner and outer, are thin iron frames, one fitting into the other, on each of which is stretched a skin of parchment or a breadth of fine cloth. A woollen blanket or two with a few sheets of paper are placed between these, the whole thus forming a thin elastic pad, on which

1494-431: A reasonably cost-effective duplicating solution for commerce at this time. The table lists the maximum number of pages which the various press designs could print per hour . General: Printing presses: Other inventions: From old price tables it can be deduced that the capacity of a printing press around 1600, assuming a fifteen-hour workday, was between 3.200 and 3.600 impressions per day. This method almost doubled

1577-477: A reservoir. In the 15th century, a new type of ink had to be developed in Europe for the printing press by Johannes Gutenberg . According to Martyn Lyons in his book Books: A Living History , Gutenberg's dye was indelible, oil-based, and made from the soot of lamps (lamp-black) mixed with varnish and egg white. Two types of ink were prevalent at the time: the Greek and Roman writing ink (soot, glue, and water) and

1660-432: A sheet at once. This began the long process of making newspapers available to a mass audience, which helped spread literacy. From the 1820s it changed the nature of book production, forcing a greater standardization in titles and other metadata . Their company Koenig & Bauer AG is still one of the world's largest manufacturers of printing presses today. The steam-powered rotary printing press , invented in 1843 in

1743-439: A thickener. When first put to paper, this ink is bluish-black. Over time it fades to a dull brown. Scribes in medieval Europe (about AD 800 to 1500) wrote principally on parchment or vellum . One 12th century ink recipe called for hawthorn branches to be cut in the spring and left to dry. Then the bark was pounded from the branches and soaked in water for eight days. The water was boiled until it thickened and turned black. Wine

1826-450: Is a type of machine press in which the ram is driven up and down by a screw. The screw shaft can be driven by a handle or a wheel. It works by using a coarse screw to convert the rotation of the handle or drive-wheel into a small downward movement of greater force. The overhead handle usually incorporates balls as flyweights . The weights helps to maintain the momentum and thrust of the tool to make it easier to operate. The screw press

1909-542: Is also credited with the introduction of an oil-based ink which was more durable than the previously used water-based inks. As printing material he used both paper and vellum (high-quality parchment). In the Gutenberg Bible , Gutenberg made a trial of colour printing for a few of the page headings, present only in some copies. A later work, the Mainz Psalter of 1453, presumably designed by Gutenberg but published under

1992-423: Is only another manifestation of the fact that this basic mechanism was foreign to that culture. Ink Ink can be a complex medium, composed of solvents , pigments, dyes , resins , lubricants , solubilizers , surfactants , particulate matter , fluorescents , and other materials. The components of inks serve many purposes; the ink's carrier, colorants, and other additives affect the flow and thickness of

2075-425: Is rolled under the platen , using a windlass mechanism. A small rotating handle called the 'rounce' is used to do this, and the impression is made with a screw that transmits pressure through the platen. To turn the screw the long handle attached to it is turned. This is known as the bar or 'Devil's Tail.' In a well-set-up press, the springiness of the paper, frisket, and tympan caused the bar to spring back and raise

2158-569: Is that carbon ink does not harm paper. Over time, the ink is chemically stable and therefore does not threaten the paper's strength. Despite these benefits, carbon ink is not ideal for permanence and ease of preservation. Carbon ink tends to smudge in humid environments and can be washed off surfaces. The best method of preserving a document written in carbon ink is to store it in a dry environment (Barrow 1972). Recently, carbon inks made from carbon nanotubes have been successfully created. They are similar in composition to traditional inks in that they use

2241-498: The 42-line Bible . After much experimentation, Gutenberg managed to overcome the difficulties which traditional water-based inks caused by soaking the paper, and found the formula for an oil-based ink suitable for high-quality printing with metal type. A printing press, in its classical form, is a standing mechanism, ranging from 5 to 7 feet (1.5 to 2.1 m) long, 3 feet (0.91 m) wide, and 7 feet (2.1 m) tall. The small individual metal letters known as type would be set up by

2324-581: The Mediterranean and medieval diet . The device was also used from very early on in urban contexts as a cloth press for printing patterns. Gutenberg may have also been inspired by the paper presses which had spread through the German lands since the late 14th century and which worked on the same mechanical principles. During the Islamic Golden Age , Arab Muslims were printing texts, including passages from

2407-609: The Qur’an , embracing the Chinese craft of paper making, developed it and adopted it widely in the Muslim world , which led to a major increase in the production of manuscript texts. In Egypt during the Fatimid era, the printing technique was adopted reproducing texts on paper strips by hand and supplying them in various copies to meet the demand. Gutenberg adopted the basic design, thereby mechanizing

2490-632: The United States by Richard M. Hoe , ultimately allowed millions of copies of a page in a single day. Mass production of printed works flourished after the transition to rolled paper, as continuous feed allowed the presses to run at a much faster pace. Hoe's original design operated at up to 2,000 revolutions per hour where each revolution deposited 4 page images, giving the press a throughput of 8,000 pages per hour. By 1891, The New York World and Philadelphia Item were operating presses producing either 90,000 4-page sheets per hour or 48,000 8-page sheets. In

2573-498: The typographical principle , the idea of creating a text by reusing individual characters, was known and had been cropping up since the 12th century and possibly before (the oldest known application dating back as far as the Phaistos disc ). The first movable type was invented by Chinese engineer Bi Sheng in the 11th century during the Song dynasty , and a book dating to 1193 recorded

2656-560: The 12th century variety composed of ferrous sulfate, gall, gum, and water. Neither of these handwriting inks could adhere to printing surfaces without creating blurs. Eventually an oily, varnish -like ink made of soot, turpentine , and walnut oil was created specifically for the printing press. Ink formulas vary, but commonly involve two components: Inks generally fall into four classes: Pigment inks are used more frequently than dyes because they are more color-fast, but they are also more expensive, less consistent in color, and have less of

2739-499: The Graeco-Roman period and subsequently. Black atramentum was also used in ancient Rome ; in an article for The Christian Science Monitor , Sharon J. Huntington describes these other historical inks: About 1,600 years ago, a popular ink recipe was created. The recipe was used for centuries. Iron salts, such as ferrous sulfate (made by treating iron with sulfuric acid), were mixed with tannin from gallnuts (they grow on trees) and

2822-577: The amount of heavy metals in ink. There is a trend toward vegetable oils rather than petroleum oils in recent years in response to a demand for better environmental sustainability performance. Ink uses up non-renewable oils and metals, which has a negative impact on the environment. Carbon inks were commonly made from lampblack or soot and a binding agent such as gum arabic or animal glue . The binding agent keeps carbon particles in suspension and adhered to paper. Carbon particles do not fade over time even when bleached or when in sunlight. One benefit

2905-646: The author was less important, since a copy of Aristotle made in Paris would not be exactly identical to one made in Bologna. For many works prior to the printing press, the name of the author has been entirely lost. Because the printing process ensured that the same information fell on the same pages, page numbering, tables of contents , and indices became common, though they previously had not been unknown. The process of reading also changed, gradually moving over several centuries from oral readings to silent, private reading. Over

2988-505: The best solution. Yet others think an aqueous procedure may preserve items written with iron gall ink. Aqueous treatments include distilled water at different temperatures, calcium hydroxide, calcium bicarbonate, magnesium carbonate, magnesium bicarbonate, and calcium hyphenate. There are many possible side effects from these treatments. There can be mechanical damage, which further weakens the paper. Paper color or ink color may change, and ink may bleed. Other consequences of aqueous treatment are

3071-621: The book existing in the format of the codex , which had originated in the Roman period . Considered the most important advance in the history of the book prior to printing itself, the codex had completely replaced the ancient scroll at the onset of the Middle Ages (AD   500). The codex holds considerable practical advantages over the scroll format: it is more convenient to read (by turning pages), more compact, and less costly, and both recto and verso sides could be used for writing or printing, unlike

3154-413: The detriment of Latin 's status as lingua franca . In the 19th century, the replacement of the hand-operated Gutenberg-style press by steam-powered rotary presses allowed printing on an industrial scale. The rapid economic and socio-cultural development of late medieval society in Europe created favorable intellectual and technological conditions for Gutenberg's improved version of the printing press:

3237-482: The earliest Chinese inks, similar to modern inksticks , is found around 256 BC, in the end of the Warring States period ; being produced from soot and animal glue . The preferred inks for drawing or painting on paper or silk are produced from the resin of the pine trees between 50 and 100 years old. The Chinese inkstick is produced with a fish glue, whereas Japanese glue (膠 nikawa ) is from cow or stag. India ink

3320-412: The ends of a bar. The wheel can either be cranked by hand or driven by a motor using a friction coupling. The wheel is weighted so its momentum will maintain the motion of the shaft. A fly press which is operated by hand is the simplest of all presses, it consists of mass, handle, body, arm, screw, ram, stop collar, treads, and guides. A planetary roller screw can provide about twice the maximum force as

3403-419: The entrepreneurial spirit of emerging capitalism increasingly made its impact on medieval modes of production, fostering economic thinking and improving the efficiency of traditional work processes. The sharp rise of medieval learning and literacy amongst the middle class led to an increased demand for books which the time-consuming hand-copying method fell far short of accommodating. Technologies preceding

Printing press - Misplaced Pages Continue

3486-526: The establishment of widely disseminated scholarly journals, helping to bring on the Scientific Revolution . Because of the printing press, authorship became more meaningful and profitable. It was suddenly important who had said or written what, and what the precise formulation and time of composition was. This allowed the exact citing of references, producing the rule, "One Author, one work (title), one piece of information" (Giesecke, 1989; 325). Before,

3569-444: The first copyright laws were passed. On the other hand, the printing press was criticized for allowing the dissemination of information that may have been incorrect. A second outgrowth of this popularization of knowledge was the decline of Latin as the language of most published works, to be replaced by the vernacular language of each area, increasing the variety of published works. The printed word also helped to unify and standardize

3652-646: The first copper movable type. This received limited use compared to woodblock printing. The technology spread outside China, as the oldest printed book using metal movable type was the Jikji , printed in Korea in 1377 during the Goryeo era. Other notable examples include the Prüfening inscription from Germany, letter tiles from England and Altarpiece of Pellegrino II in Italy. However,

3735-466: The force required by 90%, while doubling the size of the printed area. With a capacity of 480 pages per hour, the Stanhope press doubled the output of the old style press. Nonetheless, the limitations inherent to the traditional method of printing became obvious. Two ideas altered the design of the printing press radically: First, the use of steam power for running the machinery, and second the replacement of

3818-428: The fresh print. Other methods include harder paper sizing and more specialized paper coatings. The latter is particularly suited to inks used in non-industrial settings (which must conform to tighter toxicity and emission controls), such as inkjet printer inks. Another technique involves coating the paper with a charged coating. If the dye has the opposite charge, it is attracted to and retained by this coating, while

3901-446: The hole or drilling. A screw press is often used in hand book binding to help keep the covers of books flat and parallel to the text block while the glue is drying. If used as a punch, the tool itself consists of a punch and a matching die , into which it very closely fits. Both are usually precision machined and then hardened. The material is introduced between the punch and die, and the machine operated. The punch will cut through

3984-479: The imprint of his successors Johann Fust and Peter Schöffer , had elaborate red and blue printed initials. The Printing Revolution occurred when the spread of the printing press facilitated the wide circulation of information and ideas, acting as an "agent of change" through the societies that it reached. Demand for bibles and other religious literature was one of the main drivers of the very rapid initial expansion of printing. Much later, printed literature played

4067-539: The inclusion of TiO2 powder provides superior coverage and vibrant colors. Dye-based inks are generally much stronger than pigment-based inks and can produce much more color of a given density per unit of mass. However, because dyes are dissolved in the liquid phase, they have a tendency to soak into paper, potentially allowing the ink to bleed at the edges of an image. To circumvent this problem, dye-based inks are made with solvents that dry rapidly or are used with quick-drying methods of printing, such as blowing hot air on

4150-412: The ink and its dry appearance. Many ancient cultures around the world have independently discovered and formulated inks due to the need to write and draw. The recipes and techniques for the production of ink are derived from archaeological analyses or from written texts itself. The earliest inks from all civilizations are believed to have been made with lampblack , a kind of soot , easily collected as

4233-497: The intensity and appearance of dyes. Dye-based inks can be used for anti-counterfeit purposes and can be found in some gel inks, fountain pen inks, and inks used for paper currency. These inks react with cellulose to bring about a permanent color change. Dye based inks are used to color hair. There is a misconception that ink is non-toxic even if swallowed. Once ingested, ink can be hazardous to one's health. Certain inks, such as those used in digital printers, and even those found in

4316-521: The invention and global spread of the printing press was one of the most influential events in the second millennium. In Germany , around 1440, the goldsmith Johannes Gutenberg invented the movable-type printing press, which started the Printing Revolution . Modelled on the design of existing screw presses , a single Renaissance movable-type printing press could produce up to 3,600 pages per workday, compared to forty by hand-printing and

4399-463: The masses in the Reformation , and threatened the power of political and religious authorities. The sharp increase in literacy broke the monopoly of the literate elite on education and learning and bolstered the emerging middle class . Across Europe, the increasing cultural self-awareness of its peoples led to the rise of proto- nationalism and accelerated the development of European vernaculars , to

4482-424: The material in one movement by shearing it. The punch and die may be of any desired shape, so odd shaped holes and cutouts may be created. If used as a forging tool, the dies can be many different shapes varying from flat to various shapes that will mold the metal to the desired configuration. A fly press is a type of screw press in which the screw shaft is driven by a flywheel or a pair of fly weights at

4565-550: The middle of the 19th century, there was a separate development of jobbing presses , small presses capable of printing small-format pieces such as billheads , letterheads, business cards, and envelopes. Jobbing presses were capable of quick setup, with an average setup time for a small job was under 15 minutes, and quick production. Even on treadle-powered jobbing presses it was considered normal to get 1,000 impressions per hour [iph] with one pressman, with speeds of 1,500 iph often attained on simple envelope work. Job printing emerged as

4648-535: The next 200 years, the wider availability of printed materials led to a dramatic rise in the adult literacy rate throughout Europe. The printing press was an important step towards the democratization of knowledge . Within 50 or 60 years of the invention of the printing press, the entire classical canon had been reprinted and widely promulgated throughout Europe (Eisenstein, 1969; 52). More people had access to knowledge both new and old, more people could discuss these works. Book production became more commercialised, and

4731-579: The page, did not exceed an output of forty pages per day. Of Erasmus 's work, at least 750,000 copies were sold during his lifetime alone (1469–1536). In the early days of the Reformation, the revolutionary potential of bulk printing took princes and papacy alike by surprise. In the period from 1518 to 1524, the publication of books in Germany alone skyrocketed sevenfold; between 1518 and 1520, Luther 's tracts were distributed in 300,000 printed copies. The rapidity of typographical text production, as well as

4814-441: The paper, and paper composition (Barrow 1972:16). Corrosion is caused by acid catalyzed hydrolysis and iron(II)-catalysed oxidation of cellulose (Rouchon-Quillet 2004:389). Treatment is a controversial subject. No treatment undoes damage already caused by acidic ink. Deterioration can only be stopped or slowed. Some think it best not to treat the item at all for fear of the consequences. Others believe that non-aqueous procedures are

4897-399: The platen, the windlass turned again to move the bed back to its original position, the tympan and frisket raised and opened, and the printed sheet removed. Such presses were always worked by hand. After around 1800, iron presses were developed, some of which could be operated by steam power . The function of the printing press was described by William Skeen in 1872: this sketch represents

4980-430: The press that led to the press's invention included: manufacturing of paper , development of ink, woodblock printing , and invention of eyeglasses . At the same time, a number of medieval products and technological processes had reached a level of maturity which allowed their potential use for printing purposes. Gutenberg took up these far-flung strands, combined them into one complete and functioning system, and perfected

5063-457: The price of paper to one-sixth of parchment and then falling further. Papermaking centers reached Germany a century later. Despite this it appears that the final breakthrough of paper depended just as much on the rapid spread of movable-type printing. Codices of parchment, which in terms of quality is superior to any other writing material , still had a substantial share in Gutenberg's edition of

5146-453: The printing flatbed with the rotary motion of cylinders. Both elements were for the first time successfully implemented by the German printer Friedrich Koenig in a series of press designs devised between 1802 and 1818. Having moved to London in 1804, Koenig soon met Thomas Bensley and secured financial support for his project in 1807. Patented in 1810, Koenig had designed a steam press "much like

5229-416: The printing presses in operation throughout Western Europe had already produced more than twenty million copies. In the following century, their output rose tenfold to an estimated 150 to 200 million copies. European printing presses of around 1600 were capable of producing between 1,500 and 3,600 impressions per workday. By comparison, Far Eastern printing, where the back of the paper was manually rubbed to

5312-517: The printing process through all its stages by adding a number of inventions and innovations of his own: The screw press which allowed direct pressure to be applied on a flat plane was already of great antiquity in Gutenberg's time and was used for a wide range of tasks. Introduced in the 1st century AD by the Romans , it was commonly employed in agricultural production for pressing grapes for wine and olives for oil, both of which formed an integral part of

5395-499: The printing process. Printing, however, put a demand on the machine quite different from pressing. Gutenberg adapted the construction so that the pressing power exerted by the platen on the paper was now applied both evenly and with the required sudden elasticity. To speed up the printing process, he introduced a movable undertable with a plane surface on which the sheets could be swiftly changed. The concept of movable type existed prior to 15th century Europe; sporadic evidence that

5478-500: The printing speed and produced more than 40 copies a day. Printing technology reached its peak at this point. At the same time, then, as the printing press in the physical, technological sense was invented, 'the press' in the extended sense of the word also entered the historical stage. The phenomenon of publishing was born. The outstanding difference between the two ends of the Old World was the absence of screw-presses from China, but this

5561-506: The reliability of trade and led to the decline of merchant guilds and the rise of individual traders. At the dawn of the Industrial Revolution , the mechanics of the hand-operated Gutenberg-style press were still essentially unchanged, although new materials in its construction, amongst other innovations, had gradually improved its printing efficiency. By 1800, Lord Stanhope had built a press completely from cast iron which reduced

5644-483: The scroll. A fourth development was the early success of medieval papermakers at mechanizing paper manufacture. The introduction of water-powered paper mills , the first certain evidence of which dates to 1282, allowed for a massive expansion of production and replaced the laborious handcraft characteristic of both Chinese and Muslim papermaking. Papermaking centres began to multiply in the late 13th century in Italy , reducing

5727-462: The sharp fall in unit costs, led to the issuing of the first newspapers (see Relation ) which opened up an entirely new field for conveying up-to-date information to the public. Incunable are surviving pre-16th century print works which are collected by many of the libraries in Europe and North America . The printing press was also a factor in the establishment of a community of scientists who could easily communicate their discoveries through

5810-488: The sheet from contact with any thing but the inked surface of the types, when the pull, which brings down the screw and forces the platten to produce the impression, is made by the pressman who works the lever,—to whom is facetiously given the title of "the practitioner at the bar.". Johannes Gutenberg 's work on the printing press began in approximately 1436 when he partnered with Andreas Dritzehn—a man who had previously instructed in gem-cutting —and Andreas Heilmann, owner of

5893-403: The sheet to be printed is laid. The frisket is a slender frame-work, covered with coarse paper, on which an impression is first taken; the whole of the printed part is then cut out, leaving apertures exactly corresponding with the pages of type on the carriage of the press. The frisket when folded on to the tympans, and both turned down over the forme of types and run in under the platten, preserves

5976-544: The solvent soaks into the paper. Cellulose , the wood-derived material most paper is made of, is naturally charged, and so a compound that complexes with both the dye and the paper's surface aids retention at the surface. Such a compound is commonly used in ink-jet printing inks. An additional advantage of dye-based ink systems is that the dye molecules can interact with other ink ingredients, potentially allowing greater benefit as compared to pigmented inks from optical brighteners and color-enhancing agents designed to increase

6059-490: The spelling and syntax of these vernaculars, in effect 'decreasing' their variability. This rise in importance of national languages as opposed to pan-European Latin is cited as one of the causes of the rise of nationalism in Europe. A third consequence of popularization of printing was on the economy. The printing press was associated with higher levels of city growth. The publication of trade-related manuals and books teaching techniques like double-entry bookkeeping increased

6142-507: The various techniques employed (imprinting, punching and assembling individual letters) did not have the refinement and efficiency needed to become widely accepted. Tsuen-Hsuin and Needham, and Briggs and Burke suggest that the movable-type printing in China and Korea was rarely employed. Gutenberg greatly improved the process by treating typesetting and printing as two separate work steps. A goldsmith by profession, he created his type pieces from

6225-471: The writing fades to brown. The original scores of Johann Sebastian Bach are threatened by the destructive properties of iron gall ink. The majority of his works are held by the German State Library, and about 25% of those are in advanced stages of decay (American Libraries 2000). The rate at which the writing fades is based on several factors, such as proportions of ink ingredients, amount deposited on

6308-412: Was added during boiling. The ink was poured into special bags and hung in the sun. Once dried, the mixture was mixed with wine and iron salt over a fire to make the final ink. The reservoir pen, which may have been the first fountain pen , dates back to 953, when Ma'ād al-Mu'izz , the caliph of Egypt, demanded a pen that would not stain his hands or clothes, and was provided with a pen that held ink in

6391-556: Was critical for producing durable type that produced high-quality printed books and proved to be much better suited for printing than all other known materials. To create these lead types, Gutenberg used what is considered one of his most ingenious inventions, a special matrix enabling the quick and precise molding of new type blocks from a uniform template. His type case is estimated to have contained around 290 separate letter boxes, most of which were required for special characters, ligatures , punctuation marks , and so forth. Gutenberg

6474-757: Was first applied in the 1962 Indian general election , after being developed at the National Physical Laboratory of India . The election commission in India has used indelible ink for many elections. Indonesia used it in its election in 2014. In Mali, the ink is applied to the fingernail. Indelible ink itself is not infallible as it can be used to commit electoral fraud by marking opponent party members before they have chances to cast their votes. There are also reports of "indelible" ink washing off voters' fingers in Afghanistan. Screw press A screw press

6557-469: Was first invented and used by the Romans in the first century AD. It was used primarily in wine and olive oil production. The screw press was also used in Gutenberg 's printing press in the mid-15th century. A press for metalworking is a machine tool used to shape or cut metal by deforming it with a die. It is frequently used to punch holes in sheet metal in one operation, rather than by cutting

6640-537: Was in universal use in Europe". In Italy, a center of early printing, print shops had been established in 77 cities and towns by 1500. At the end of the following century, 151 locations in Italy had seen at one time printing activities, with a total of nearly three thousand printers known to be active. Despite this proliferation, printing centres soon emerged; thus, one third of the Italian printers published in Venice . By 1500,

6723-402: Was invented in China, though materials were often traded from India, hence the name. The traditional Chinese method of making the ink was to grind a mixture of hide glue, carbon black , lampblack, and bone black pigment with a pestle and mortar , then pour it into a ceramic dish to dry. To use the dry mixture, a wet brush would be applied until it reliquified. The manufacture of India ink

6806-420: Was then applied to the text evenly. One damp piece of paper was then taken from a heap of paper and placed on the tympan. The paper was damp as this lets the type 'bite' into the paper better. Small pins hold the paper in place. The paper is now held between a frisket and tympan (two frames covered with paper or parchment). These are folded down, so that the paper lies on the surface of the inked type. The bed

6889-567: Was well-established by the Cao Wei dynasty (220–265 AD). Indian documents written in Kharosthi with ink have been unearthed in Xinjiang . The practice of writing with ink and a sharp pointed needle was common in early South India. Several Buddhist and Jain sutras in India were compiled in ink. Cephalopod ink , known as sepia , turns from dark blue-black to brown on drying, and was used as an ink in
