Risograph is a stencil printing process. Each colour uses its own ink drum and stencil, then layers onto uncoated paper. Translucent inks can overlap to create new tones. Slight shifts between layers and variations in ink coverage are part of its character.

PDF is preferred. For separated artwork, provide one grayscale file per ink colour and label each file with the intended colour and side. Include a full-colour reference so we can see how the layers should combine. For raster images, aim for 300 dpi at the final print size.

A3 is our largest offered sheet size: 297 × 420 mm. Riso does not print right to the edge. Leave space around your artwork; we will confirm the printable area and trimming before production. Upload PDF, JPG, PNG, TIFF or ZIP: up to 8 files, 20 MB each, 50 MB total.
