01 — The idea
An isometric mark is the hardest thing to letterpress. Facets want tonal separation, and letterpress gives you one ink.
Client
A brass and bronze casting foundry
Construction
One continuous ribbon, folded twice. Every fold between two faces is a white channel of a single consistent width, so nothing depends on a mid-tone.
03 — On light
Iron Black on Concrete
03 — On dark
Molten Bronze on Iron Black
05 — Clear space
Clear space equals the height of the ribbon's narrowest facet on all four sides.
Minimum 16 mm wide. Below that, the favicon lockup.
06 — Scale
Favicon: the top facet alone, squared. Below 12 mm the wordmark is dropped and the symbol stands alone.
08 — Typography

09 — Do and do not
✓Separate every facet with a white channel of one width
✓Print the folds as gaps, never as a second tone
✓Keep solid faces under 12 mm across
✕Never render a facet in a lighter shade of the ink
✕Never add a keyline around the ribbon
✕Never foil the mark — reflection fights the flat facets

A studio identity exercise. Mark, palette, type system and usage rules by the Print Peppermint design team.
Every identity we build ships with the file the press needs: vector mark, one-colour version, favicon set, Pantone Uncoated references and a guide like this one.
