Our Colours
All inks are translucent — overlapping layers create secondary tones. Hex codes are approximate; screen rendering varies from print output.
Riso inks are transparent — layering two colours creates a third. Yellow + Blue makes green, Pink + Blue makes purple, Orange + Blue makes brown. Mix intentionally.

How we print
Every print we make is hands-on. We work with you from file prep to final trim — if you're new to Riso or Giclée, we'll guide you through it.
01 Format & Margins +
Max sheet size is 297 × 420 mm (A3) with a max image area of 287 × 410 mm. Keep at least 5 mm safe margins all around — 10 mm for dense ink areas. Avoid full-bleed right to the edge.
02 Colour & Coverage +
Each pass is transparent — overlapping inks create new tones. Avoid dense fills at 100%; use 80–90% opacity for large colour areas. Flat colours may print unevenly — typical with big ink blocks.
03 Text & Lines +
Minimum font size is 6 pt. Avoid very thin fonts or line weights under 0.25 pt. For small type, use solid black only — no layered inks.
04 Paper +
We print exclusively on uncoated paper, FSC-certified stock. Weight range 80g to 300g. We frequently work with Fedrigoni papers from Italy and locally sourced papers from Barcelona.
05 File Setup +
Submit one flattened, greyscale PDF per colour layer. PSDs with colour layers accepted for A3. 300 dpi minimum. Include a colour reference preview (RGB or CMYK OK).
06 Production Notes +
Minimum run is 30 copies. Riso is a duplicator — each layer prints via stencil and drum. Expect slight shifts, texture, and roller marks. Oil-based inks are slow-drying, especially in multi-layer prints.
