About
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.
SIX REAL PRINT PROCESSES
* Riso Duotone — pink + cobalt ink 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
Each one is a genuinely different rendering pipeline — not one
filter with six color presets.
EVERY VALUE IS A SLIDER
Ink color, screen angle, dot width, and misregistration strength —
nothing is hardcoded to a preset. Dial in your own look.
LIVE PREVIEW, FULL PRINT AT CAPTURE
The viewfinder shows a fast live approximation; pressing the shutter
applies the complete multi-plate overprint — every ink plate,
composited with the same intentional plate misregistration real
risograph and offset printing has.
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 five
mechanisms: Riso Duotone, Flat Screenprint, Offset Newsprint,
Engraving, and Mimeograph.

* HEIC capture, saved straight to a dedicated "Chroia" album in your
Photos library — no separate account, no cloud
* The mechanism you shot with is written into every photo's own EXIF
* English and Japanese from day one
