## About Alfa Slab One

Alfa Slab One is a display typeface in the Egyptian, or slab serif, tradition, pushed to a very heavy weight. Stems are so thick that the counters of a, e and B shrink to small openings, and the rectangular serifs are nearly as heavy as the stems they sit on. The official description says the design started from Robert Thorne's Six-lines Pica Egyptian, made for the Thorowgood Foundry, and departs from it with heavier stems, bigger serifs and more contrast. The font has one style. Its file reports weight 400, Regular, even though the letters are as dark as a black weight; there is no lighter cut or italic. The 731 glyphs cover Latin, Latin Extended and Vietnamese. JM Solé is credited as designer, and the copyright notice reserves the font name Alfa Slab. The license is the SIL Open Font License 1.1.

## Where it works

- **Poster headlines**: Extreme stem weight and block serifs fill a line with black, so two or three words can anchor a whole poster.
- **Shop signs and window lettering**: Heavy slab serifs keep their shape when cut large in vinyl or painted, in the manner of the Egyptian faces the design starts from.
- **Packaging and labels**: A short product name in Alfa Slab One stays dominant even on a crowded label.
- **Sports and event graphics**: Numerals are as heavy as the letters, which suits scores, dates and big figures.

## Things to know

- **Labelled Regular, drawn black**: The only file is Regular 400. Asking for bold in software produces a synthetic thickening of an already very heavy face.
- **Counters are small**: The openings inside a, e, g and 8 are tiny in the specimen and close up further as the size drops.
- **Reserved font name**: The copyright notice reserves the name Alfa Slab; modified versions need another name unless permission is given.
