Halftone & Riso
Screen any image into a halftone, two-colour duotone, or full Risograph-style spot-colour separation — for plates, zines, posters and graphic poché. Adjustable dot shape, ruling and screen angle, real Riso inks, mis-registration and grain, over any paper colour. Export a finished PNG, per-ink plate masters for an actual Risograph, or vector SVG dots for print / plotter / laser. Client-side.
Drop an image onto the preview, click Load, or paste with Ctrl/Cmd+V. Nothing is uploaded — it all runs in your browser.
A starting point — every control below stays editable.
Two inks — a key plate + a shadow accent.
Each plate prints in its own ink at its own angle; offsets & jitter are the printerly mis-registration.
Sets the size of what comes out. The files come from Export at the top of the page: Composite PNG is the finished art (paper + over-print + grain), Vector SVG is real vector dots for crisp print, plotter or laser, and each plate is a black-on-transparent master for an actual Risograph.
One drawing, two registers
Riso two-tone (soft). Warm, handmade, forgiving — reads as a proposal, still open to change.
1-bit Floyd–Steinberg. Technical, brutal, exact — every pixel a decision; reads as a verdict.
Same drawing, two voices. Which serves your story?
The medium is part of the argument: a soft riso print proposes, a hard 1-bit dither pronounces a verdict, a fine halftone just reports. If you've written a position statement for your project (your brief's story), pick the register that argues for it — then look hard at what the other voice does to the same information.
