Read full description

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. EVERYTHING ELSE YOU'D EXPECT * 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 No ads. No tracking.
