Chroia: Riso Print Camera

A camera that reproduces risograph printing — multi-plate color
separation, halftone dot screens, and intentional plate
misregistration, rendered live in your viewfinder and applied in
full the moment you press the shutter.

SEVEN REAL PRINT PROCESSES

* Riso Duotone — color-separated into pink + cobalt plates, overprinted
* Flat Screenprint — halftone-free spot color
* Offset Newsprint — a genuine CMY rosette, vintage press texture
* Photocopy — Xerox-style decay and scan noise (free)
* Engraving — single-plate crosshatch
* Mimeograph — blocky ink blotches
* Spot Color Halftone — the most saturated color survives a black dot screen

Each one is a genuinely different rendering pipeline — not one
filter with seven color presets.

EVERY VALUE IS A SLIDER

Pick a catalog spot ink or mix your own with hue, saturation, and
brightness — plus paper stock and paper grain, screen angle, dot
width, halftone dots or riso grain, and misregistration strength.
Nothing is hardcoded to a preset. Dial in your own look.

WHAT YOU SEE IS WHAT YOU PRINT

Riso Duotone and every single-plate process render in full in the
viewfinder — every ink plate and the intentional misregistration,
exactly as saved. Offset Newsprint previews one CMY plate live for
speed and composites all three at the shutter.

FREE TO START

Shoot with Photocopy at no cost. Full Unlock is a single one-time
purchase ($5.99, not a subscription) that opens the other six
mechanisms: Riso Duotone, Flat Screenprint, Offset Newsprint,
Engraving, Mimeograph, and Spot Color Halftone.
