Phosphate Font is a bold, all-caps sans-serif display typeface designed by Steve Jackaman (ITF) and Ashley Muir (type designer at Red Rooster) in 2010. It’s a digital reinterpretation of the 1923 typeface Phosphor by Ludwig & Mayer, known for its strong industrial and retro aesthetic.
Phosphate font
The Phosphate font is available only in all caps, and it has only two styles. However, both types have RR Inline and RR Solid, OpenType features, and standard texture ligatures and glimpses. Initially, the font was published by International TypeFounders; the family was based on the “Phosphor” typeface, created by Jacob Erbar for Ludwig and Mayer, circa 1922–30.
However, the font has 64 glyphs. There are variants of the K and Y in the font, and it offers no lower-case characters. This font supports at least 33 languages, and the splendid textual glimpses and high-grade legibility of the font make it people’s favorite. A digital interpretation of Phosphor (Ludwig & Mayer, 1923) added a solid style.
