We are not taking online orders yet — that part of the website is coming soon. In the meantime, here’s everything you need to know so your files are ready to go when we are.

Color tip: Riso inks are translucent, so their final appearance depends on the paper color. Colors can be overprinted to create new ones - for example, pink on yellow paper creates a red effect!

Preparing your files

Riso prints one colour at a time, so your artwork needs to be split into separate layers — one per ink colour. Each layer should be a greyscale image where black = full ink and white = no ink. Opacity/grey values give you halftones.

Technical requirements

Format: PDF (preferred), PSD, AI, PNG, or TIFF
Resolution: 300 dpi minimum; 600 dpi for text-heavy work
Size: A3 only (297 × 420 mm) — A4, A5, and postcards are printed multiple-up on A3
Margins: At least 8 mm on all sides
One file per colour: label them clearly — e.g. poster_yellow.pdf, poster_blue.pdf
Colour mode: Greyscale (or RGB where R=G=B). 0% = white (no ink), 100% = black (full ink)

Design tips

Riso inks are translucent — colours overprint and mix. Pink over yellow reads as orange, blue over yellow reads as green. Plan your overlaps.
Allow 1–3 mm misregistration between layers — Riso isn’t a laser printer and that’s part of the charm. Designs where layers slightly miss each other can look great.
Avoid very fine lines (under 1 pt) and very small text (under 8 pt) — they can fill or break.
Large solid areas tend to look best at 85% or less — 100% solid blocks can get patchy. For fine illustrations, go wild.
Use flat colour or halftone rather than gradients where possible — Riso halftones have a distinctive coarse dot that’s part of the aesthetic.
The paper colour counts as a colour. Cream paper with one blue ink is already a two-colour print.

Not sure? Send us a flat version of your design and we’ll work with you on the separation. Any pre-press work beyond simple file checks may incur a small fee, but we’ll always tell you before we do anything.

What Riso printing is like

The good stuff

Vivid, almost fluorescent inks that photograph beautifully
A tactile quality — you can feel the ink on the page
Fast and relatively affordable for short-to-medium runs
Every print is very slightly unique

The charming quirks

Misregistration: 1–3 mm shift between colour passes is normal and expected
Roller marks: Occasionally visible on large flat areas — usually adds character
Ink variation: The first few and last few sheets of a run can be slightly lighter or darker
Smudging: Riso ink takes a little time to fully cure — avoid stacking fresh prints face-to-face
