All About Color

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.

Successful Layout & Design

Art Nouveau Typography

By Carl Shank • September 6, 2025
Art Nouveau fonts grew out of the late 19th-century Art Nouveau movement (c. 1890–1910), which sought to break away from academic, historicist styles and create a new art for the modern age. The style flourished across Europe and America in architecture, furniture, illustration, and typography. In lettering, Art Nouveau embraced organic forms, flowing curves, floral motifs, and asymmetry, reflecting the movement’s fascination with natural growth and hand-drawn ornament. Art Nouveau took its name from the Maison de l'Art Nouveau, a Parisian gallery that exhibited the works of artists and designers who were associated with the movement. The style was characterized by flowing, curvilinear forms inspired by natural shapes and motifs such as flowers, vines, and insects. It also incorporated elements from other artistic traditions, such as Japanese art and the Arts and Crafts movement. Art Nouveau was particularly popular in Europe, where it influenced a wide range of artistic disciplines, including architecture, interior design, furniture, jewelry, and graphic design. Some of the most notable Art Nouveau architects included Hector Guimard, Antoni Gaudí, and Victor Horta, while artists such as Alphonse Mucha, Aubrey Beardsley, and Gustav Klimt were celebrated for their decorative and ornamental works. Art Nouveau declined in popularity after World War I, as artists and designers began to embrace new, more modernist styles. However, its influence can still be seen in many aspects of contemporary design, and it remains an important and influential movement in the history of art and design. 

Ornamental Gothics

Gothics History. Gothic typefaces are a broad group of styles rooted in medieval calligraphy and evolved into distinct print types during and after the invention of movable type via Gutenberg in the 15th century. They are sometimes confusingly named. In Europe “Gothic” usually refers to blackletter (medieval scripts), while in the U.S. “Gothic” often refers to sans-serif typefaces since the 1830s. Gothic script is a broad term for the entire family of medieval European scripts that developed from Carolingian minuscule around the twelfth century. “Minuscules” are lower case letters as distinct from capital letters, or uncials. Type developed in the sixth through tenth centuries with modern lettering evolving from Carolingian scripts. The Emperor Charlemagne used these letters as an educational standard. These densely packed scripts featured tall, narrow letterforms, strong vertical emphasis, sharp, angular connections, a dramatic thick/thin contrast and minimal spacing between letters. Gothic-inspired fonts create immediate medieval impact and work beautifully for titles, logos, and short display text. They are used today in Fantasy Gaming, Historical Projects, Themed Entertainment (like the Renaissance Fair), Book Design, Certificates, Breweries and Distilleries. Jack Nolan, a professional graphics designer, has provided a fetching display of such faces in his "33 Medieval Fonts Perfect for ‘Ye Olde’ Designs in 2025."(1)
