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 — 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
* 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 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.
