All About Color

Carl Shank • September 5, 2022

All About Color. In modern typography and printing, the use of color, once thought too expensive, is now commonplace. Color laser printers are found in many offices, churches and certainly printer shops. Not many people, however, understand the science of color and how we get colored images and scans to the printed page. So, while I am certainly no expert in color technology, here are a few definitions and pointers in color printing.


DPI vs LPI. Let's start at the beginning. Every laser printer has a DPI, or dots per inch, that it places on a sheet of paper. Many older laser printers are rated at least at 300 DPI, with many more today at 600 DPI and above. What is DPI? Dots Per Inch (DPI) is literally a measurement of the maximum number of dots any printer has access to per inch. The dots reference the unit in which all printers and computers are measured, namely, binary code. As such, each dot is either off or on. These dots make up a grid pattern which can only print in black and white. There are no colors or shades of colors (such as grey). The higher the DPI the "smoother" the print looks to the human eye.


LPI, or Lines per Inch, is a measurement of the number of rounded dots that are in an inch. LPI is also known as a screen, and is given its name because each rounded dot has a centre point that’s created in varying sizes. The LPI is directly related to the DPI which is directly related to resolution. Depending on the resolution, one may acquire a picture that seems ‘grainier’ than others – that is, pixilated. For instance, to get a dot that actually appears round rather than square, or pixilated, one must have a DPI of at least 600. A glossy magazine is usually printed with an LPI of 150; as it relates to DPI, which means that the resolution was 2400 DPI or higher. 53 LPI is typical of an office laser. Newspapers are about 90 LPI.


Halftones. We use halftones to print tints. This uniform field of small dots lets paper show through. The more paper that shows through, the lighter the tint. The bigger the spots, the darker the tint. A halftone is measured in lines per inch (LPI). The more lines per inch, the finer the halftone (See Sample Below). To camouflage the rows of spots, a halftone is printed at an angle. If we printed a black halftone at 0 degrees we would see the rows of dots. So printing at an angle tricks our eyes so that we do not realize we are seeing rows and columns of dots at all. Now we are ready to talk about color.


About Color. Color exists as an effect of light. The white light from say the sun is made up of a rainbow of impulses that our brain interprets as colors. All the colors of the rainbow, when added up, make a white light. They are called primary additive colors. (See "All About Color" below.) Computer monitors use three primary colors —Red, Green and Blue—otherwise know as RGB. Since the colors of objects are really white light minus the waves absorbed by the object, they are called primary subtractive colors, otherwise knows as printing colors, or CMYK colors—Cyan, made up of blue and green, Magenta, made up of blue and red, Yellow, made up of red and green. (See "All About Color" below). The K color is actually Black, usually added to give strength and body to a printed picture or image.


Color separations are used for each of the four process colors by a professional lithographic printer. The final result of a color separation is four sheets of film, one for each of the process colors. The films are then used to create the four plates of a process-color printing press.


Going back to halftone angles. Black, the most visible, is printed at a 45 degree angle, Cyan at a 75 degree angle, Magenta at a 15 degree angle, and Yellow at a 0 degree angle. Four halftones are superimposed on each other. To minimize any interference patterns (called "moirés") the halftones are angled 30 degrees apart, yielding a tight, nondistracting compilation. Technological improvements now create microdots that don't use any angles at all. The spots now fall side by side, not atop one another and fit so neatly together that the viewer is unaware spots even exist in their image or photo.

German Typography History

By Carl Shank • August 31, 2026
German Typography History German typography has a particularly distinctive history because Germany was central to the invention of European movable-type printing, the development of Gothic/Blackletter typography, the rise of Fraktur, and later the modernist rejection of traditional German type. The story therefore moves dramatically from manuscript Gothic forms to highly ornate Fraktur, then to Bauhaus modernism and finally to contemporary digital typography. The history can be understood as a series of major transformations, as noted in ChatGPT, Gothic manuscript → Gutenberg → Schwabacher → Fraktur → Roman/Gothic duality → nineteenth-century industrial typography → Bauhaus modernism → New Typography → postwar modernism → digital pluralism. What makes German typography particularly fascinating is that the political and cultural meaning of type was unusually strong. Fraktur was not simply a letterform; over time it became associated with German language and identity, while the twentieth-century modernists deliberately sought to replace that historical visual language with an international, functional one. If you're studying European typography comparatively, German typography makes an especially useful contrast with Italian, French, Dutch, and English typography, because Germany's long attachment to Gothic type produced a very different trajectory from the Roman-type tradition that developed in Italy and subsequently dominated much of Western Europe. A number of Blogs I have written gives one an insight as to German historical typography and its central typographic characters, including typefaces and notes about Johannes Gutenberg, Marin Luther in Gothic type, Fraktur type and its extensive use in Germany, Rudolph Koch, the Bauhaus period with Herbert Bayer and Paul Renner, Futura, Jan Tschichold and Die Neue Typographie, and the influence of the Akzidenz-Grotesk font and its relationship to Helvetica, Univers, Neue Haas Grotesk, and Arial.

Contemporary Germany has become one of Europe's major centers of type design. Important contemporary designers and foundries include Erik Spiekermann. Erik Spiekermann (born1947)( is a German art historian, typographer, designer, information architect and writer. He divides his time between Berlin, London and San Francisco. He runs Hacking Gutenberg, an experimental letterpress printing workshop in Berlin. He wrote Stop Stealing Sheep & Find Out How Type Works , a book on typography first published in 1993, revised 4th edition 2023. Spiekermann has designed numerous typefaces, both for sale and as part of corporate design programs. His typefaces include Berliner Grotesk (original is from 1913, digitization is from c. 1978), Fira Sans (designed in collaboration with Ralph du Carrois) for Firefox OS, released in 2013 under the SIL Open Font License), ITC Officina Sans and Serif fonts (1990), and FF Meta. FF Meta is especially interesting, as one of the fonts illustrated by axis-praxis for variable font use. It has 28 Instances offered through Adobe, from Condensed through Black, and a Variable font from Monotype. Spiekermann’s work emphasizes information clarity, signage, corporate identity, wayfinding, and digital typography. In German typography, wayfinding refers to the use of typography, symbols, color, spatial organization, and signs to help people navigate a physical environment. It is closely associated with Germany’s strong tradition of functionalist and systematic graphic design. Modern German typography is characterized by pluralism rather than a single national style. Contemporary designers freely use sans serifs, serif typefaces, variable fonts, neo-grotesques, geometric sans serifs, humanist sans serifs, contemporary revivals of Fraktur, experimental lettering, and digital display fonts. Fraktur remains visible in specialized contexts such as traditional breweries, historic businesses, newspapers and publications with historical associations, certificates, Blackletter music and cultural graphics, and Gothic/medieval-themed design, However, it is no longer the default German text type.

Italian Typography History (2)

By Carl Shank • August 29, 2026
Italian Typography and Futurism. One of Italy's most important contributions to twentieth-century graphic design came from Futurism. Beginning around 1909, Italian Futurists challenged conventional typography. The most important figure was Filippo Tommaso Marinetti. His Zang Tumb Tumb and related works used typography dynamically rather than simply as a vehicle for continuous reading. Zang Tumb Tumb is a sound and concrete poem appearing in journals between 1912 and 1914, when it was published as an artist’s book in Milan. It is an account of the Battle of Adrianople. The poem uses Parole in libertà (words in freedom; creative typography) and other poetic impressions of the events of the battle, including the sounds of gunfire and explosions. The work is now seen as a seminal work of modernist art, and an enormous influence on the emerging culture of European avant-garde print. (Wikipedia)
