57-434: In digital printing , a page description language ( PDL ) is a computer language that describes the appearance of a printed page in a higher level than an actual output bitmap (or generally raster graphics ). An overlapping term is printer control language , which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages. The markup language adaptation of

114-420: A binder. Watercolor painters before the turn of the 18th century had to make paints themselves using pigments purchased from an apothecary or specialized "colorman", and mixing them with gum arabic or some other binder. The earliest commercial paints were small, resinous blocks that had to be wetted and laboriously "rubbed out" in water to obtain a usable color intensity. William Reeves started his business as

171-536: A binder. Originally (in the 16th to 18th centuries), watercolor binders were sugars and/or hide glues, but since the 19th century, the preferred binder is natural gum arabic , with glycerin and/or honey as additives to improve plasticity and solubility of the binder, and with other chemicals added to improve product shelf life. The term " bodycolor " refers to paint that is opaque rather than transparent. It usually refers to opaque watercolor, known as gouache . Modern acrylic paints use an acrylic resin dispersion as

228-906: A circular cross section, and a constant, tapered, or variable diameter. Digital cylinder printing is a method of reproducing black-and-white or full-color images and text onto cylindrical objects, typically promotional products, through use of digital imaging systems. The digital process is by definition faster than conventional screen printing , because it requires fewer production steps and less set-up time for multiple colors and more complex jobs. This in turn enables reduced run lengths. The ability of digital cylinder printing machines to print full color in one pass, including primers, varnishes and specialty inks, enables multiple design techniques, which include: Full-wrap cylindrical printing also benefits from seamless borders with no visual overlap. For ease of print file preparation, original design artwork should be able to be imaged on cylinders and tapered items without

285-630: A colorman around 1766. In 1781, he and his brother, Thomas Reeves, were awarded the Silver Palette of the Society of Arts , for the invention of the moist watercolor paint-cake , a time-saving convenience, introduced in the "golden age" of English watercolor painting. The "cake" was immediately soluble when touched by a wet brush. Modern commercial watercolor paints are available in tubes, pans and liquids. The majority of paints sold today are in collapsible small metal tubes in standard sizes and formulated to

342-508: A consistency similar to toothpaste by being already mixed with a certain water component. For use, this paste has to be further diluted with water. Pan paints (actually small dried cakes or bars of paint in an open plastic container) are usually sold in two sizes, full pans and half pans. Owing to modern industrial organic chemistry , the variety, saturation , and permanence of artists' colors available today has been vastly improved. Correct and non-toxic primary colors are now present through

399-435: A higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates . It also allows for on-demand printing, short turnaround time , and even a modification of the image (variable data) used for each impression. The savings in labor and the ever-increasing capability of digital presses means that digital printing

456-453: A mixed-media work. Many terms for the process have been used over the years, including "digigraph" and "giclée". Thousands of print shops and digital printmakers now offer services to painters, photographers, and digital artists around the world. Digital images are exposed onto true, light sensitive photographic paper with lasers and processed in photographic developers and fixers. These prints are true photographs and have continuous tone in

513-549: A print head mechanism in which tiny droplets of CMYK (cyan, magenta, yellow, and black) inks are released in a specific pattern to form an image. Typically, one part is printed at a time and can require from 8 to 45 seconds to complete, depending on artwork complexity and quality. It is then finished with a UV coating to add a glossy finish and protect it from abrasion. There are three different imaging techniques used by digital cylinder printing machines: multi-pass, single pass, and helical printing. Multi-Pass: Multi-pass printing

570-411: A series of hugely popular books describing his picturesque journeys throughout rural England, and illustrated them with self-made sentimentalized monochrome watercolors of river valleys, ancient castles, and abandoned churches. This example popularized watercolors as a form of personal tourist journal. The confluence of these cultural, engineering, scientific, tourist, and amateur interests culminated in

627-563: A watercolor tutorial by English art critic John Ruskin , has been out of print only once since it was first published in 1857. Commercial brands of watercolor were marketed and paints were packaged in metal tubes or as dry cakes that could be "rubbed out" (dissolved) in studio porcelain or used in portable metal paint boxes in the field. Breakthroughs in chemistry made many new pigments available, including synthetic ultramarine blue , cobalt blue , viridian , cobalt violet , cadmium yellow , aureolin ( potassium cobaltinitrite ), zinc white , and

684-446: A weight at least 300 gsm (140 lb). Under 300 gsm (140 lb) is commonly not recommended for anything but sketching. Transparency is the main characteristic of watercolors. Watercolors can also be made opaque by adding Chinese white . This is not a method to be used in "true watercolor" (traditional). Watercolor paint is an ancient form of painting, if not the most ancient form of art itself. In East Asia, watercolor painting with inks

741-647: A wide range of carmine and madder lakes . These pigments, in turn, stimulated a greater use of color with all painting media, but in English watercolors, particularly by the Pre-Raphaelite Brotherhood . Watercolor painting also became popular in the United States during the 19th century; outstanding early practitioners included John James Audubon , as well as early Hudson River School painters such as William H. Bartlett and George Harvey . By mid-century,

798-418: A wider industrial use. Paint manufacturers buy, by industrial standards very small, supplies of these pigments, mill them with the vehicle, solvent, and additives, and package them. The milling process with inorganic pigments, in more expensive brands, reduces the particle size to improve the color flow when the paint is applied with water. In the partisan debates of the 19th-century English art world, gouache

855-794: Is Building 6 Portrait: Interior. Produced by American artist Barbara Prey on commission for MASS MoCA , the work can be seen at MASS MoCA's Robert W. Wilson Building. Although the rise of abstract expressionism , and the trivializing influence of amateur painters and advertising- or workshop-influenced painting styles, led to a temporary decline in the popularity of watercolor painting after c.  1950 , watercolors continue to be utilized by artists like Martha Burchfield , Joseph Raffael , Andrew Wyeth , Philip Pearlstein , Eric Fischl , Gerhard Richter , Anselm Kiefer , and Francesco Clemente . In Spain, Ceferí Olivé created an innovative style followed by his students, such as Rafael Alonso López-Montero and Francesc Torné Gavaldà . In Mexico ,

912-465: Is a painting method in which the paints are made of pigments suspended in a water-based solution. Watercolor refers to both the medium and the resulting artwork . Aquarelles painted with water-soluble colored ink instead of modern water colors are called aquarellum atramento ( Latin for "aquarelle made with ink") by experts. However, this term has now tended to pass out of use. The conventional and most common support —material to which

969-969: Is a hybrid method between the single-pass and multi-pass approaches. Image data is mapped to allow continuous imaging in a helical pattern with a limited number of print heads. Users can optimize the print resolution, speed, and curing controls to optimize image quality or choose higher speed if quality isn't critical. Tapers can be imaged at high speed and curved vessels can be managed through the range of controls offered. Items that can be printed using digital cylindrical processes include cups, tumblers, thermos bottles, bottles, makeup containers, machine parts, carrier tubes, pens, tubes, jars and others. Digital printing has many advantages over traditional methods. Some applications of note include: Watercolor painting#Paper Watercolor ( American English ) or watercolour ( British English ; see spelling differences ), also aquarelle ( French: [akwaʁɛl] ; from Italian diminutive of Latin aqua 'water'),

1026-434: Is more expensive on a per-print basis than the traditional four-color offset lithography , but with inkjet printing the artist does not have to pay for the expensive printing-plate setup or the marketing and storage needed for large four-color offset print runs. Inkjet reproductions can be printed and sold individually in accordance with demand. Inkjet printing has the added advantage of allowing artists to take total control of

1083-433: Is reaching the point where it can match or supersede offset printing technology's ability to produce larger print runs of several thousand sheets at a low price. The greatest difference between digital printing and analog methods, such as lithography , flexography , gravure , and letterpress , is that in digital printing (introduced in the 1980s) there is no need to replace the printing plate , whereas in analog printing

1140-427: Is referred to as brush painting or scroll painting. In Chinese , Korean and Japanese painting it has been the dominant medium, often in monochrome black or browns, often using inkstick or other pigments. India, Ethiopia and other countries have long watercolor painting traditions as well. Many Western artists, especially in the early 19th century, used watercolor primarily as a sketching tool in preparation for

1197-522: Is when the print heads or printed object move axially in steps down the part, like a flatbed printer . The move time is inefficient and can lead to stitching artifacts between moves. Single Pass: Single pass involves using an array of print heads to print the full image length with a single revolution of the printed object. Different colors are usually printed at different stations, leading to higher cost, increased complexity, and sensitivity to print nozzle drop-outs.   Helical Printing: Helical printing

1254-707: The Royal Institute of Painters in Water Colours ). (A Scottish Society of Painters in Water Colour was founded in 1878, now known as the Royal Scottish Society of Painters in Watercolour .) These societies provided annual exhibitions and buyer referrals for many artists. They also engaged in petty status rivalries and aesthetic debates, particularly between advocates of traditional ("transparent") watercolor and

1311-575: The Society of Dilettanti (founded in 1733), to document discoveries in the Mediterranean, Asia, and the New World. These expeditions stimulated the demand for topographical painters, who churned out memento paintings of famous sites (and sights) along the Grand Tour to Italy that was undertaken by every fashionable young man of the time. In the late 18th century, the English cleric William Gilpin wrote

1368-402: The paper surface; the transparency is caused by the paper being visible between the particles. Watercolors may appear more vivid than acrylics or oils because the pigments are laid down in a purer form, with few or no fillers (such as kaolin) obscuring the pigment colors. Typically, most or all of the gum binder will be absorbed by the paper, preventing the binder from changing the visibility of

1425-418: The "father of the English watercolor"; Thomas Girtin (1775–1802), who pioneered its use for large format, romantic or picturesque landscape painting; and Joseph Mallord William Turner (1775–1851), who brought watercolor painting to the highest pitch of power and refinement, and created hundreds of superb historical, topographical, architectural, and mythological watercolor paintings. His method of developing

1482-478: The "finished" work in oil or engraving. Until the end of the eighteenth century, traditional watercolors were known as 'tinted drawings'. Watercolor art dates back to the cave paintings of paleolithic Europe and has been used for manuscript illustration since at least Egyptian times , with particular prominence in the European Middle Ages . However, its continuous history as an art medium begins with

1539-656: The 1920s to 1940s. In particular, the " Cleveland School " or "Ohio School" of painters centered around the Cleveland Museum of Art , and the California Scene painters were often associated with Hollywood animation studios or the Chouinard Art Institute (now California Institute of the Arts ). The California painters exploited their state's varied geography, Mediterranean climate, and " automobility " to reinvigorate

1596-730: The 19th century with artists such as John James Audubon , and today many naturalist field guides are still illustrated with watercolor paintings. Several factors contributed to the spread of watercolor painting during the 18th century, particularly in England. Among the elite and aristocratic classes, watercolor painting was one of the incidental adornments of a good education; mapmakers, military officers, and engineers valued it for its usefulness in depicting properties, terrain, fortifications, field geology, and for illustrating public works or commissioned projects. Watercolor artists were commonly taken on geological or archaeological expeditions, funded by

1653-512: The British Museum in 1857, led to a negative reevaluation of the permanence of pigments in watercolor. This caused a sharp decline in their status and market value. Nevertheless, isolated practitioners continued to prefer and develop the medium into the 20th century. Paul Signac created landscape and maritime watercolors, and Paul Cézanne developed a watercolor painting style consisting entirely of overlapping small glazes of pure color. Among

1710-487: The PDL is the page description markup language. Page description languages are text (human-readable) or binary data streams, usually intermixed with text or graphics to be printed. They are distinct from graphics application programming interfaces (APIs) such as GDI and OpenGL that can be called by software to generate graphical output. Various page description languages exist: Digital printing Digital printing has

1767-988: The Renaissance . The German Northern Renaissance artist Albrecht Dürer (1471–1528), who painted several fine botanical, wildlife, and landscape watercolors, is generally considered among the earliest examples of watercolor. An important school of watercolor painting in Germany was led by Hans Bol (1534–1593) as part of the Dürer Renaissance . Despite this early start, watercolors were generally used by Baroque easel painters only for sketches, copies or cartoons (full-scale design drawings) Notable early practitioners of watercolor painting were Van Dyck (during his stay in England), Claude Lorrain , Giovanni Benedetto Castiglione , and many Dutch and Flemish artists. However, botanical illustration and wildlife illustration perhaps form

1824-470: The artwork. The traditional claim that "transparent" watercolors gain "luminosity" because they function like a pane of stained glass laid on paper—the color intensified because the light passes through the pigment, reflects from the paper, and passes a second time through the pigment on its way to the viewer—is false. Watercolor paints typically do not form a cohesive paint layer, as do acrylic or oil paints, but simply scatter pigment particles randomly across

1881-497: The celebration and promotion of watercolor as a distinctly English "national art". William Blake published several books of hand-tinted engraved poetry, provided illustrations to Dante's Inferno , and he also experimented with large monotype works in watercolor. Among the many other significant watercolorists of this period were Thomas Gainsborough , John Robert Cozens , Francis Towne , Michael Angelo Rooker , William Pars , Thomas Hearne , and John Warwick Smith . From

1938-522: The early adopters of the denser color possible with body color or gouache ("opaque" watercolor). The late Georgian and Victorian periods produced the zenith of the British watercolor, among the most impressive 19th-century works on paper, due to artists Turner, Varley, Cotman, David Cox , Peter de Wint William Henry Hunt , John Frederick Lewis , Myles Birket Foster , Frederick Walker , Thomas Collier , Arthur Melville and many others. In particular,

1995-406: The graceful, lapidary, and atmospheric watercolors ("genre paintings") by Richard Parkes Bonington created an international fad for watercolor painting, especially in England and France in the 1820s. In the latter half of the 19th century, portrait painter Frederick Havill became a key player in the establishment of watercolour in England. Art critic Huntly Carter described Havill as a "founder of

2052-408: The image detail. The archival quality of the print is as high as the manufacturer's rating for any given photo paper used. In large format prints, the greatest advantage is that, since no lens is used, there is no vignetting or detail distortion in the corners of the image. Digital cylinder printing is when a machine directly lays ink onto a curved surface that usually is the wall of an object that has

2109-662: The influence of John Ruskin led to increasing interest in watercolors, particularly the use of a detailed "Ruskinian" style by such artists as John W. Hill Henry, William Trost Richards , Roderick Newman , and Fidelia Bridges . The American Society of Painters in Watercolor (now the American Watercolor Society ) was founded in 1866. Late-19th-century American exponents of the medium included Thomas Moran , Thomas Eakins , John LaFarge , John Singer Sargent , Childe Hassam , and, preeminently, Winslow Homer . Watercolor

2166-470: The introduction of hansa yellow , phthalo blue and quinacridone (PV 122). From such a set of three colors, in principle all others can be mixed, as in a classical technique no white is used. The modern development of pigments was not driven by artistic demand. The art materials industry is too small to exert any market leverage on global dye or pigment manufacture. With rare exceptions such as aureolin, all modern watercolor paints utilize pigments that have

2223-645: The late 18th century through the 19th century, the market for printed books and domestic art contributed substantially to the growth of the medium. Watercolors were used as the basic document from which collectible landscape or tourist engravings were developed, and hand-painted watercolor originals or copies of famous paintings contributed to many upper class art portfolios. Satirical broadsides by Thomas Rowlandson , many published by Rudolph Ackermann , were also extremely popular. The three English artists credited with establishing watercolor as an independent, mature painting medium are Paul Sandby (1730–1809), often called

2280-465: The major exponents are Ignacio Barrios , Edgardo Coghlan , Ángel Mauro , Vicente Mendiola , and Pastor Velázquez . In the Canary Islands , where this pictorial technique has many followers, there are stand-out artists such as Francisco Bonnín Guerín, José Comas Quesada , and Alberto Manrique. Watercolor paint consists of four principal ingredients: a pigment ; gum arabic as a binder to hold

2337-532: The many 20th-century artists who produced important works in watercolor were Wassily Kandinsky , Emil Nolde , Paul Klee , Egon Schiele , and Raoul Dufy . In America, the major exponents included Charles Burchfield , Edward Hopper , Georgia O'Keeffe , Charles Demuth , and John Marin (80% of his total work is watercolor). In this period, American watercolor painting often emulated European Impressionism and Post-Impressionism, but significant individualism flourished in "regional" styles of watercolor painting from

2394-404: The need for manipulation or distortion; i.e., flat images will print to scale on a curved surface, with software automatically making the adjustment. The more advanced systems available on the market can handle these requirements. The digital cylindrical printing process involves inserting a cylinder-shaped item, or part, into a fixture, which securely holds it in place. The part then travels under

2451-557: The oldest and most important traditions in watercolor painting. Botanical illustrations became popular during the Renaissance, both as hand-tinted woodblock illustrations in books or broadsheets and as tinted ink drawings on vellum or paper. Botanical artists have traditionally been some of the most exacting and accomplished watercolor painters, and even today, watercolors—with their unique ability to summarize, clarify, and idealize in full color—are used to illustrate scientific and museum publications. Wildlife illustration reached its peak in

2508-486: The outdoor or "plein air" tradition. The most influential among them were Phil Dike , Millard Sheets , Rex Brandt , Dong Kingman , and Milford Zornes . The California Water Color Society, founded in 1921 and later renamed the National Watercolor Society, sponsored important exhibitions of their work. The largest watercolor in the world at the moment (at 9 feet (3 m) tall and 16 ft (5 m) wide)

2565-550: The paint is applied—for watercolor paintings is watercolor paper . Other supports or substrates include stone, ivory, silk, reed, papyrus , bark papers, plastics, vellum , leather , fabric , wood, and watercolor canvas (coated with a gesso that is specially formulated for use with watercolors). Watercolor paper is often made entirely or partially with cotton. This gives the surface the appropriate texture and minimizes distortion when wet. Watercolor papers are usually cold-pressed papers that provide better texture and appearance with

2622-622: The pigment in suspension; additives like glycerin , ox gall , honey , and preservatives to alter the viscosity , hiding, durability or color of the pigment and vehicle mixture; and, evaporating water, as a solvent used to thin or dilute the paint for application. The more general term watermedia refers to any painting medium that uses water as a solvent and that can be applied with a brush , pen , or sprayer. This includes most inks , watercolors , temperas , caseins , gouaches , and modern acrylic paints . The term "watercolor" refers to paints that use water-soluble, complex carbohydrates as

2679-434: The plates are repeatedly replaced. This results in quicker turnaround time and lower cost in digital printing, but typically a loss of detail in most commercial digital printing processes. The most popular methods include inkjet and laser printers , which deposit pigment and toner, respectively, onto substrates, such as paper, canvas, glass, metal, and marble. In many of the processes, the ink or toner does not permeate

2736-409: The production of their images, including the final color correction and the substrates being used, with some artists owning and operating their own printers. Digital inkjet printing also allows for the output of digital art of all types as finished pieces or as an element in a further art piece. Experimental artists often add texture or other media to the surface of a final print, or use it as part of

2793-455: The satirist Honoré Daumier . Other European painters who worked frequently in watercolor were Adolph Menzel in Germany and Stanisław Masłowski in Poland. The adoption of brightly colored, petroleum-derived aniline dyes (and pigments compounded from them), which all fade rapidly on exposure to light, and the efforts to properly conserve the twenty thousand J. M. W. Turner paintings inherited by

2850-536: The substrate, as does conventional ink, but forms a thin layer on the surface that may be additionally adhered to the substrate by a fuser fluid with thermal (toner) or ultraviolet curing (ink). Fine art digital inkjet printing is printing from a computer image file directly to an inkjet printer as a final output. It evolved from digital proofing technology from Kodak , 3M , and other major manufacturers, with artists and other printers trying to adapt these dedicated prepress proofing machines to fine-art printing. There

2907-413: The water colour school." The popularity of watercolors stimulated many innovations, including heavier and more sized wove papers , and brushes (called "pencils") manufactured expressly for watercolor. Watercolor tutorials were first published in this period by Varley, Cox, and others, establishing the step-by-step painting instructions that still characterize the genre today; The Elements of Drawing ,

2964-600: The watercolor painting in stages, starting with large, vague color areas established on wet paper, then refining the image through a sequence of washes and glazes, permitted him to produce large numbers of paintings with "workshop efficiency" and made him a multimillionaire, partly by sales from his personal art gallery, the first of its kind. Among the important and highly talented contemporaries of Turner and Girtin were John Varley , John Sell Cotman , Anthony Copley Fielding , Samuel Palmer , William Havell , and Samuel Prout . The Swiss painter Abraham-Louis-Rodolphe Ducros

3021-540: Was also widely known for his large format, romantic paintings in watercolor. The confluence of amateur activity, publishing markets, middle class art collecting , and 19th-century technique led to the formation of English watercolor painting societies: the Society of Painters in Water Colours (1804, now known as the Royal Watercolour Society ) and the New Water Colour Society (1832, now known as

3078-421: Was emphatically contrasted to traditional watercolors and denigrated for its high hiding power or lack of "transparency"; "transparent" watercolors were exalted. The aversion to opaque paint had its origin in the fact that well into the 19th century lead white was used to increase the covering quality. That pigment tended to soon discolor into black under the influence of sulphurous air pollution, totally ruining

3135-565: Was experimentation with many of these types of printers, the most notable being the IRIS printer , initially adapted to fine-art printing by programmer David Coons , and adopted for fine-art work by Graham Nash at his Nash Editions printing company in 1991. Initially, these printers were limited to glossy papers, but the IRIS Graphics printer allowed the use of a variety of papers that included traditional and non-traditional media. The IRIS printer

3192-655: Was less popular in Continental Europe. In the 18th century, gouache was an important medium for the Italian artists Marco Ricci and Francesco Zuccarelli , whose landscape paintings were widely collected. Gouache was used by a number of artists in France as well. In the 19th century, the influence of the English school helped popularize "transparent" watercolor in France, and it became an important medium for Eugène Delacroix , François Marius Granet , Henri-Joseph Harpignies , and

3249-654: Was the standard for fine art digital printmaking for many years, and is still in use today, but has been superseded by large-format printers from other manufacturers such as Epson and HP that use fade-resistant, archival inks ( pigment -based, as well as newer solvent -based inks), and archival substrates specifically designed for fine-art printing. Substrates in fine art inkjet printmaking include traditional fine-art papers such as Rives BFK, Arches watercolor paper , treated and untreated canvas, experimental substrates (such as metal and plastic), and fabric. For artists making reproductions of their original work, inkjet printing
