Philosophy

Two families do all the work. F37 Jan is the voice of our ideas — a British grotesque with warmth and teeth. Ioskeley Mono is the voice of our machinery — an industrial terminal face for data, labels, codes, and the quiet scaffolding around the work.

No third family. No decorative weight. If a design needs a third voice, the answer is always contrast of size and case, not typeface.

Do / Don't 02

DO
Set headlines tight — negative tracking, leading under 1.0.
DO
Use mono for metadata, labels, codes, timestamps, units.
DO
Mix display and mono for texture, not for hierarchy.
DON'T
Italicise — neither family has true italics; rely on weight and colour.
DON'T
Underline body type. Underlines are reserved for links.
DON'T
Set body copy in mono. It's a texture, not a reading face.

Display headlines do the persuading. Mono captions do the verifying. The two never compete for voice.

Crafted in Newcastle.
Ref AL6061-T6 · ⌀ 160mm
Orange display type earns attention sparingly — one accent per composition. Everything else wears black or the off-white surface.
Blockquote

The function of the machine is to allow us to think more efficiently and effectively.

Alan Turing

Usage 03

DO
Reserve blockquotes for attributed quotes — real speech, real sources.
DO
Use <cite> for the attribution; style it in mono caps.
DON'T
Pull-quote decorative copy. Use a hero or callout component instead.
DON'T
Italicise the quote text — weight and the accent colour carry emphasis.
