Risograph style: scenes printed like a riso print, in four spot inks (fluorescent pink, yellow, blue, navy) on warm paper, flat and halftone plates, overprints that make the other colours, misregistration, uneven inking and grain. Use it for riso, screen print, halftone, retro print, zine or «printed» looks, or when working with styles/risograph/.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Style · Risograph
Approved (the user signed off the study at round 3). Studied on `references/opus5-risograph.mp4`: a 1:1 study of the whole
28 s film in `sandbox/2026-09-24-opus5-riso/` (43 cards, circles, mosaic, orbits, title).
## Code
`styles/risograph/riso.js` → global `Riso`.
- `const press = Riso.press(env)` once in `setup`; per frame `press.begin(d)`, draw, then
`press.print(g, { key: d })` (memoised per drawing: the print is pixel work, ~150 ms).
- **Plates, not colours.** `press.plate(ink, 'solid' | 'screen')` gives a context in logical
units; draw with `Riso.tone(v)` (only the alpha counts: how much ink). A solid plate prints
flat ink; a screen plate turns tones into halftone dots (a dot per cell, area = tone),
each ink at its own screen angle. `Riso.ramp`/`radial` make tone gradients.
- **Whites are knockouts:** `press.knockout(fn)` erases a shape from every plate.
- Helpers: `Riso.line` (a hand-inked polyline), `Riso.ring` (a wobbling circle, drawn on
with `p` 0..1).
- The press: paper colour with grain, inks multiplied in order yellow → pink → blue → navy,
per-ink register offsets (`register`), starved blotches and pinholes, a slight spread

How to install
mdr add illodev/drawn-by-code/style-risograph@sha256:5f1f1927e97785a3The line at the top of this page pins the label git:20261002.7d0e422, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
