The format we work with is A3!
The Riso printer doesn’t print with bleed, so you always need to keep a 10mm margin around your artwork.
Within the format of A3, you can fit 2 x A4, 4 x A5, 8 x A6 - always keeping in mind the 10mm margin.
The artwork should be flattened before exporting to PDF file, without transparencies or effects.
PDF file should be in greyscale, 300dpi and real size (A3)
Each colour of your design needs to be in a separate PDF file, named after your chosen colour.
We also ask for a JPG mock-up preview in colour, so that we can do our best at getting as close as possible to the desired final result and spot any errors before it’s too late!
