Chroma — Risograph effect, duotone and CMYK separation
Classic Riso · layer 2 shifted 5 px
01 What it is
One image, several passes of ink.
Chroma cuts the photo into layers — one per ink — and lets you choose each colour, its coverage, its position. Shift one by four pixels and it’s a real riso print, imperfect registration included.
42 official Riso ink combinations, 348 harmonies from Sanzo Wada’s Dictionary of Color Combinations, and masters exported for the printer.

Riso
Blue and fluorescent pink, one layer slightly askew: Hokusai’s wave through the drum.

Palettes
Colours laid in layers like a Saul Bass poster: few inks, clearly separated values.

Official inks
The real Riso inks, named and coded: what you see is what the printer can pull.
04
Registration
Blue, fluorescent pink and yellow, the second layer slid six pixels and turned half a degree: the misregistration becomes the drawing.
