95-424: A glyph ( / ɡ l ɪ f / GLIF ) is any kind of purposeful mark. In typography , a glyph is "the specific shape, design, or representation of a character". It is a particular graphical representation, in a particular typeface , of an element of written language. A grapheme , or part of a grapheme (such as a diacritic ), or sometimes several graphemes in combination (a composed glyph) can be represented by
190-453: A type designer to create customized typefaces for their exclusive use. Different periodicals design their publications, including their typography, to achieve a particular tone or style. For example, USA Today uses a bold, colorful, and comparatively modern style through their use of a variety of typefaces and colors; type sizes vary widely, and the newspaper's name is placed on a colored background. In contrast, The New York Times uses

Before the 1980s, practically all typesetting for publishers and advertisers was performed by specialist typesetting companies. These companies performed keyboarding, editing and production of paper or film output, and formed a large component of
380-415: A body of text can instantaneously reveal the mood the author intends to convey to its readers. The message that a body of text conveys has a direct relationship with the typeface that is chosen. Therefore, when a person focuses on typography and setting type, they must pay very close attention to the typeface they choose. Choosing the correct typeface for a body of text can only be done after thoroughly reading
475-402: A case, contained cast metal sorts , each with a single letter or symbol, but backwards (so they would print correctly). The compositor assembled these sorts into words, then lines, then pages of text, which were then bound tightly together by a frame, making up a form or page. If done correctly, all letters were of the same height, and a flat surface of type was created. The form was placed in
570-401: A family of typesetting languages with names that were derivatives of the word "SCRIPT". Later versions of SCRIPT included advanced features, such as automatic generation of a table of contents and index, multicolumn page layout, footnotes, boxes, automatic hyphenation and spelling verification. NSCRIPT was a port of SCRIPT to OS and TSO from CP-67/CMS SCRIPT. Waterloo Script was created at
665-439: A glyph is a graphical unit. Typography Typography is the art and technique of arranging type to make written language legible , readable and appealing when displayed. The arrangement of type involves selecting typefaces , point sizes , line lengths , line spacing , letter spacing , and spaces between pairs of letters . The term typography is also applied to the style, arrangement, and appearance of
760-519: A glyph. In most languages written in any variety of the Latin alphabet except English, the use of diacritics to signify a sound mutation is common. For example, the grapheme ⟨à⟩ requires two glyphs: the basic a and the grave accent ` . In general, a diacritic is regarded as a glyph, even if it is contiguous with the rest of the character like a cedilla in French , Catalan or Portuguese ,
855-405: A key difference. Much of the legibility research literature is atheoretical—various factors were tested individually or in combination (inevitably so, as the different factors are interdependent), but many tests lacked a model of reading or visual perception. Some typographers believe that the overall word shape ( Bouma ) is essential in readability and that the theory of parallel letter recognition
950-472: A keyboard or other devices could produce the desired text. Most of the successful systems involved the in-house casting of the type to be used, hence are termed "hot metal" typesetting. The Linotype machine , invented in 1884, used a keyboard to assemble the casting matrices, and cast an entire line of type at a time (hence its name). In the Monotype System , a keyboard was used to punch a paper tape , which
1045-489: A language's orthography for visual display. Typesetting requires one or more fonts (which are widely but erroneously confused with and substituted for typefaces ). One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission. During much of the letterpress era , movable type was composed by hand for each page by workers called compositors . A tray with many dividers, called

Choice of typefaces is the primary aspect of text typography— prose fiction , non-fiction , editorial, educational, religious, scientific, spiritual, and commercial writing all have differing characteristics and requirements of appropriate typefaces (and their fonts or styles). For historic material, established text typefaces frequently are chosen according to
1330-410: A more traditional approach, with fewer colors, less typeface variation, and more columns . Especially on the front page of newspapers and on magazine covers, headlines often are set in larger display typefaces to attract attention, and are placed near the masthead . Typography utilized to characterize text: Typography is intended to reveal the character of the text. Through the use of typography,
1425-512: A press and inked, and then printed (an impression made) on paper. Metal type read backwards, from right to left, and a key skill of the compositor was their ability to read this backwards text. Before computers were invented, and thus becoming computerized (or digital) typesetting, font sizes were changed by replacing the characters with a different size of type. In letterpress printing, individual letters and punctuation marks were cast on small metal blocks, known as "sorts," and then arranged to form
1520-412: A product. Legibility describes how easily individual characters can be distinguished from one another. It is described by Walter Tracy as "the quality of being decipherable and recognisable". For instance, if a b and an h , or a 3 and an 8 , are difficult to distinguish at small sizes, this is a problem of legibility. Typographers are concerned with legibility insofar as it is their job to select
1615-423: A scheme of historical genre acquired by a long process of accretion, with considerable overlap among historical periods. Contemporary books are more likely to be set with state-of-the-art "text romans" or "book romans" typefaces with serifs and design values echoing present-day design arts, which are closely based on traditional models such as those of Nicolas Jenson , Francesco Griffo (a punchcutter who created
1710-492: A single glyph. Older models of typewriters required the use of multiple glyphs to depict a single character, as an overstruck apostrophe and period to create an exclamation mark . If there is more than one allograph of a unit of writing, and the choice between them depends on context or on the preference of the author, they now have to be treated as separate glyphs, because mechanical arrangements have to be available to differentiate between them and to print whichever of them
1805-415: A single unit, is arguably not a glyph as this is just a design choice of that typeface, essentially an allographic feature, and includes more than one grapheme . In normal handwriting, even long words are often written "joined up", without the pen leaving the paper, and the form of each written letter will often vary depending on which letters precede and follow it, but that does not make the whole word into
1900-479: A solvent the expensive sorts had to be redistributed into the typecase - called sorting or dissing - so they would be ready for reuse. Errors in sorting could later produce misprints if, say, a p was put into the b compartment. The diagram at right illustrates a cast metal sort: a face, b body or shank, c point size, 1 shoulder, 2 nick, 3 groove, 4 foot. Wooden printing sorts were used for centuries in combination with metal type. Not shown, and more
1995-464: A surface by rolling the seal on wet clay. Typography was also implemented in the Phaistos Disc , an enigmatic Minoan printed item from Crete , which dates to between 1850 and 1600 B.C. It has been proposed that Roman lead pipe inscriptions were created with movable type printing, but German typographer Herbert Brekle recently dismissed this view.

Traditionally, text is composed to create a readable, coherent, and visually satisfying block of type that works invisibly, without the awareness of the reader. Even distribution of typeset material, with

The LaTeX macro package, written by Leslie Lamport at the beginning of the 1980s, offered a simpler interface and an easier way to systematically encode the structure of a document. LaTeX markup is widely used in academic circles for published papers and books. Although standard TeX does not provide an interface of any sort, there are programs that do. These programs include Scientific Workplace and LyX , which are graphical/interactive editors; TeXmacs , while being an independent typesetting system, can also aid
2280-451: Is customary to insert a non-breaking space before a colon (:) or semicolon (;) in a sentence, while in English it is not. In typesetting, color is the overall density of the ink on the page, determined mainly by the typeface, but also by the word spacing, leading , and depth of the margins. Text layout, tone, or color of the set text, and the interplay of text with the white space of

Other topics, such as justified vs. unjustified type, use of hyphens, and proper typefaces for people with reading difficulties such as dyslexia , continue to be debated. Legibility is usually measured through the speed of reading, with comprehension scores used to check for effectiveness (that is, not a rushed or careless read). For example, Miles Tinker , who published numerous studies from
2470-407: Is often used to draw attention to a particular advertisement, combined with efficient use of color, shapes, and images. In the early twenty-first century, typography in advertising often reflects a company's brand . A brand may use typography to express its theme, personality, and message. Just by looking at the typeface, viewers can get an idea about the message and personality of the brand, which
2565-587: Is required. In computing as well as typography, the term " character " refers to a grapheme or grapheme-like unit of text, as found in natural language writing systems ( scripts ). In typography and computing, the range of graphemes is broader than in a written language in other ways too: a typeface often has to cope with a range of different languages each of which contribute their own graphemes, and it may also be required to print non-linguistic symbols such as dingbats . The range of glyphs required increases correspondingly. In summary, in typography and computing,

Some versions, as well as a GNU work-alike called groff , are now open source . The TeX system, developed by Donald E. Knuth at the end of the 1970s, is another widespread and powerful automated typesetting system that has set high standards, especially for typesetting mathematics. LuaTeX and LuaLaTeX are variants of TeX and of LaTeX scriptable in Lua . TeX

Word shape differs by outline, influenced by ascending and descending elements of lowercase letters and enables reading the entire word without having to parse out each letter. Readability also may be compromised by letter-spacing , word spacing, or leading that is too tight or too loose. It may be improved when generous vertical space separates text lines, making it easier for

Improvements in software and hardware, and rapidly lowering costs, popularized desktop publishing and enabled very fine control of typeset results much less expensively than the minicomputer dedicated systems. At the same time, word processing systems, such as Wang , WordPerfect and Microsoft Word , revolutionized office documents. They did not, however, have

Although these marks originally had no independent meaning, they have since acquired meaning in the field of mathematics and computing, for instance. Conversely, in the languages of Western Europe, the dot on a lower-case ⟨i⟩ is not a glyph in itself because it does not convey any distinction, and an ⟨ı⟩ in which

Experimental typography is said to place emphasis on expressing emotion, rather than having a concern for legibility while communicating ideas, hence considered bordering on being art. There are many facets to the expressive use of typography, and with those come many different techniques to help with visual aid and

However, even a legible typeface can become unreadable through poor setting and placement, just as a less legible typeface can be made more readable through good design. Studies of both legibility and readability have examined a wide range of factors including type size and type design, comparing serif vs. sans-serif type, roman type vs. oblique type and italic type , line length , line spacing, color contrast,

In this process, called stereotyping , the entire form is pressed into a fine matrix such as plaster of Paris or papier mâché to create a flong , from which a positive form is cast in type metal . Advances such as the typewriter and computer would push the state of the art even farther ahead. Still, hand composition and letterpress printing have not fallen completely out of use, and since

Typefaces used in advertisements convey different messages to the reader: classical ones are for a strong personality, while more modern ones may convey clean, neutral look. Bold typefaces are used for making statements and attracting attention. In any design, a balance has to be achieved between the visual impact and communication aspects. Digital technology in

"Experimental typography" is defined as the unconventional and more artistic approach to typeface selection. Francis Picabia was a Dada pioneer of this practice in the early twentieth century. David Carson is often associated with this movement, particularly for his work in Ray Gun magazine in
4370-484: The concern of the casterman, is the "set", or width of each sort. Set width, like body size, is measured in points. In order to extend the working life of type, and to account for the finite sorts in a case of type, copies of forms were cast when anticipating subsequent printings of a text, freeing the costly type for other work. This was particularly prevalent in book and newspaper work where rotary presses required type forms to wrap an impression cylinder rather than set in
4465-487: The conversion to do-it-yourself easier, but also opened up a gap between skilled designers and amateurs. The advent of PostScript, supplemented by the PDF file format, provided a universal method of proofing designs and layouts, readable on major computers and operating systems. QuarkXPress had enjoyed a market share of 95% in the 1990s, but lost its dominance to Adobe InDesign from the mid-2000s onward. IBM created and inspired
4560-744: The correct font to use. Brush script is an example of a font containing many characters that might be difficult to distinguish. The selection of cases influences the legibility of typography because using only uppercase letters (all-caps) reduces legibility. Readability refers to how easy it is to read the text as a whole, as opposed to the individual character recognition described by legibility. Use of margins, word and line spacing, and clear document structure all impact readability. Some fonts or font styles, for instance sans-serif fonts, are considered to have low readability and so are unsuited for large quantities of prose. Legibility "refers to perception" (being able to see as determined by physical limitations of

Justified copy must be adjusted tightly during typesetting to prevent loss of readability, something beyond the capabilities of typical personal computers. Legibility research has been published since the late nineteenth century. Although there often are commonalities and agreement on many topics, others often create poignant areas of conflict and variation of opinion. For example, Alex Poole asserts that no one has conclusively answered which typeface style, serif or sans serif,
4750-431: The details of letter design are magnified. Color is used for its emotional effect in conveying the tone and nature of subject matter. Display typography encompasses: Typography has long been a vital part of promotional material and advertising . Designers often use typefaces to set a theme and mood in an advertisement (for example, using bold, large text to convey a particular message to the reader). Choice of typeface
4845-497: The development of typesetting systems. Although typography has evolved significantly from its origins, it is a largely conservative art that tends to cleave closely to tradition. This is because legibility is paramount, and so the typefaces that are the most readable usually are retained. In addition, the evolution of typography is inextricably intertwined with lettering by hand and related art forms, especially formal styles, which thrived for centuries preceding typography, and so

However, in Turkish and adjacent languages, this dot is a glyph because that language has two distinct versions of the letter i , with and without a dot . In Japanese syllabaries , some of the characters are made up of more than one separate mark, but in general these separate marks are not glyphs because they have no meaning by themselves. However, in some cases, additional marks fulfil
5035-439: The end of the twentieth century was to pair a sans-serif typeface for headings with a high-performance serif typeface of matching style for the text of an article. Typesetting conventions are modulated by orthography and linguistics , word structures, word frequencies, morphology , phonetic constructs and linguistic syntax . Typesetting conventions also are subject to specific cultural conventions. For example, in French it
5130-428: The evolution of typography must be discussed with reference to this relationship. In the nascent stages of European printing , the typeface ( blackletter , or Gothic) was designed in imitation of the popular hand-lettering styles of scribes . Initially, this typeface was difficult to read, because each letter was set in place individually and made to fit tightly into the allocated space. The art of manuscript writing,

Underlining also may reduce readability by eliminating the recognition effect contributed by the descending elements of letters. Periodical publications, especially newspapers and magazines, use typographical elements to achieve an attractive, distinctive appearance, to aid readers in navigating

"The typeface chosen should be legible. That is, it should be read without effort. Sometimes legibility is simply a matter of type size; more often, however, it is a matter of typeface design. Case selection always influences legibility. In general, typefaces that are true to

Currently , legibility research tends to be limited to critical issues or the testing of specific design solutions (for example, when new typefaces are developed).

The uneven spacing of the impressions on brick stamps found in the Mesopotamian cities of Uruk and Larsa , dating from the second millennium B.C. , may be evidence of type, wherein the reuse of identical characters was applied to create cuneiform text. Babylonian cylinder seals were used to create an impression on

Greek lapidary letters were carved into stone and "one of the first formal uses of Western letterforms "; after that, Roman lapidary letterforms evolved into the monumental capitals, which laid the foundation for Western typographical design, especially serif typefaces. There are two styles of Roman typefaces:

With printed media, typographers also are concerned with binding margins, paper selection, and printing methods when determining the correct color of the page. Three fundamental aspects of typography are legibility , readability , and aesthetics . Although in a non-technical sense "legible" and "readable" are often used synonymously, typographically they are separate but related concepts.

A compositor would need to physically swap out the sorts for a different size to change the font size. During typesetting, individual sorts are picked from a type case with the right hand, and set from left to right into a composing stick held in the left hand, appearing to the typesetter as upside down. As seen in
7315-666: The text from conveying its message to readers. A study from 2020 found that the participating subjects felt music sounded "more pleasant" when the CD cover featured round typeface. Type may be combined with negative space and images, forming relationships and dialog between the words and images for special effects. Display designs are a potent element in graphic design . Some sign designers exhibit less concern for readability, sacrificing it for an artistic manner. Color and size of type elements may be much more prevalent than in solely text designs. Most display items exploit type at larger sizes, where
7410-423: The text, understanding its context, and understanding what the text is wishing to convey. Once the typographer has an understanding of the text, then they have the responsibility of using the appropriate typeface to honor the writing done by the author of the text. Knowledge required to choose the correct typeface comes with understanding the historical background of typefaces and understanding the reason that typeface
7505-589: The text. Although typography can potentially attract the reader's attention and create a beautiful/attractive piece of text, the craft of typography is not limited to the aesthetic appeal of the text. On the contrary, the object of typography is to make the reading experience practical and useful. Bold colors, multiple typefaces, and colorful backgrounds in a typographic design may be eye-catching; however, it may not be appropriate for all bodies of text and could potentially make text illegible. Overuse of design elements such as colors and typefaces can be unsettling, preventing
7600-407: The title to convey its importance, which directly informs the reader of the structure in which the text is intended to be read, and increases readability from varying distances. Typography utilized to make reading practical: Typography not only must honor the tone of the text but also share the responsibility of making the audience commence reading and sustaining the audience's attention throughout
7695-475: The twentieth and twenty-first centuries has enabled the creation of typefaces for advertising that are more experimental than traditional typefaces. Typesetting Typesetting is the composition of text for publication, display, or distribution by means of arranging physical type (or sort ) in mechanical systems or glyphs in digital systems representing characters (letters and other symbols). Stored types are retrieved and ordered according to
7790-423: The twentieth century, computers turned typeface design into a rather simplified process. This has allowed the number of typefaces and styles to proliferate exponentially, as there now are thousands available. Confusion between typeface and font (the various styles of a single typeface) occurred in 1984 when Steve Jobs mislabeled typefaces as fonts for Apple computers and his error has been perpetuated throughout
7885-638: The type were the Alphanumeric APS2 (1963), IBM 2680 (1967), I.I.I. VideoComp (1973?), Autologic APS5 (1975), and Linotron 202 (1978). These machines were the mainstay of phototypesetting for much of the 1970s and 1980s. Such machines could be "driven online" by a computer front-end system or took their data from magnetic tape. Type fonts were stored digitally on conventional magnetic disk drives. Computers excel at automatically typesetting and correcting documents. Character-by-character, computer-aided phototypesetting was, in turn, rapidly rendered obsolete in
7980-542: The typographic ability or flexibility required for complicated book layout, graphics, mathematics, or advanced hyphenation and justification rules ( H and J ). By 2000, this industry segment had shrunk because publishers were now capable of integrating typesetting and graphic design on their own in-house computers. Many found the cost of maintaining high standards of typographic design and technical skill made it more economical to outsource to freelancers and graphic design specialists. The availability of cheap or free fonts made
8075-631: The vast quantities required to print multiple copies of texts. This technical breakthrough was instrumental in starting the Printing Revolution and the first book printed with lead-based movable type was the Gutenberg Bible . Rapidly advancing technology revolutionized typography in the latter twentieth century. During the 1960s some camera-ready typesetting could be produced in any office or workshop with stand-alone machines such as those introduced by IBM (see: IBM Selectric typewriter ). During
8170-521: The words are formed by assembling single letter tiles in the desired order, which were reasonably widespread in medieval Northern Europe. Typography with movable type was invented during the eleventh-century Song dynasty in China by Bi Sheng (990–1051). His movable type system was manufactured from ceramic materials, and clay type printing continued to be practiced in China until the Qing dynasty . Wang Zhen
8265-509: Was a SCRIPT variant developed at IBM in the 1980s. DWScript is a version of SCRIPT for MS-DOS, named after its author, D. D. Williams, but was never released to the public and only used internally by IBM. Script is still available from IBM as part of the Document Composition Facility for the z/OS operating system. The standard generalized markup language ( SGML ) was based upon IBM Generalized Markup Language (GML). GML
8360-631: Was a set of macros on top of IBM Script. DSSSL is an international standard developed to provide a stylesheets for SGML documents. XML is a successor of SGML. XSL-FO is most often used to generate PDF files from XML files. The arrival of SGML/XML as the document model made other typesetting engines popular. Such engines include Datalogics Pager, Penta, Miles 33's OASYS, Xyvision's XML Professional Publisher , FrameMaker , and Arbortext . XSL-FO compatible engines include Apache FOP , Antenna House Formatter , and RenderX 's XEP . These products allow users to program their SGML/XML typesetting process with
8455-452: Was created. For example, if the text is titled "Commercial Real Estate Transactions" and elaborates on the real estate market throughout the body, then the appropriate typeface is a serif typeface, because the author intends to inform his audience on a serious topic and not entertain his audience with an anecdote; a serif typeface would convey a sense of seriousness to the audience instantaneously. The typographer would also employ larger type for
8550-542: Was documented in the May 1975 issue of the Computing Centre Newsletter, which noted some the advantages of using SCRIPT: The article also pointed out SCRIPT had over 100 commands to assist in formatting documents, though 8 to 10 of these commands were sufficient to complete most formatting jobs. Thus, SCRIPT had many of the capabilities computer users generally associate with contemporary word processors. SCRIPT/VS
8645-465: Was limited and the technology did not spread beyond East and Central Asia, however. Modern lead-based movable type, along with the mechanical printing press , is most often attributed to the goldsmith Johannes Gutenberg in 1439. His type pieces, made from a lead -based alloy , suited printing purposes so well that the alloy is still used today. Gutenberg developed specialized techniques for casting and combining cheap copies of letter punches in
8740-594: Was met by medieval print artifacts such as the Latin Pruefening Abbey inscription of 1119 that was created by the same technique as the Phaistos Disc. The silver altarpiece of patriarch Pellegrinus II (1195–1204) in the cathedral of Cividale was printed with individual letter punches. Apparently, the same printing technique may be found in tenth to twelfth century Byzantine reliquaries . Other early examples include individual letter tiles where
8835-549: Was one of the pioneers of wooden movable type . Although the wooden type was more durable under the mechanical rigors of handling, repeated printing wore the character faces down and the types could be replaced only by carving new pieces. Metal movable type was first invented in Korea during the Goryeo Dynasty , approximately 1230. Hua Sui introduced bronze type printing to China in 1490 AD. The diffusion of both movable-type systems
8930-460: Was then fed to control a casting machine. The Ludlow Typograph involved hand-set matrices, but otherwise used hot metal. By the early 20th century, the various systems were nearly universal in large newspapers and publishing houses. Phototypesetting or "cold type" systems first appeared in the early 1960s and rapidly displaced continuous casting machines. These devices consisted of glass or film disks or strips (one per font ) that spun in front of
9025-419: Was typed a second time. If the two lines were identical a bell rang and the machine produced a punched paper tape corresponding to the text. With the completion of a block of lines the typesetter fed the corresponding paper tapes into a phototypesetting device that mechanically set type outlines printed on glass sheets into place for exposure onto a negative film . Photosensitive paper was exposed to light through
