We aim to work with environmentally friendly paper. We stock different papers in different grammages from Metapaper, Biotop, Kraft, Malmero, EOS, and Crush by Favini that is made from organic waste such as coffee or citrus peels. We can also order paper for you, to fit your specific needs. We have several paper sample books, for you to browse through. All these samples have been printed one-sided so you know what the result would be. You can also bring your own paper. Keep in mind this must be uncoated and generally between 80-250gr. Generally add 10-15% paper, for misprints and such. Pay attention to the grain of the paper; the machine prefers to work in the short grain direction. Before committing to a final product on your own paper, we would like to make a test print to see how it works out. Color results can vary, depending on what paper is used.


Riso colors are one of a kind. All colors, except metallic, are rich semitransparent spot colors. This means you can layer them to create new, exciting colors by overlaying and blending the inks. If you want to print full color (CMYK) image with Riso, please keep in mind that it will never be 100% accurate, since the colors cyan and magenta do not exist in the Riso range. However, printing with different color profiles, that resemble CMYK, enables faux CMYK printing that gives a surreal and slightly psychedelic result (e.g. aqua, fluorescent pink, yellow and black) We have a few standard 2, 3 and 4 color profiles.

We have different binding possibilities ourselves and offer other external binding options. Tell us what you want and we'll find a way! 



Riso has a printing resolution up to 600dpi, either with grain touch or rasterized. For optimal Riso results of your design, please follow these guidelines:

Separate your file per color layer in greyscale or b/w

Save as PDF and add in the document name the color in which you want that PDF to be printed: e.g.: myprintAQUA.pdf and myprintBLACK.pdf

Make sure your file is flattened; no layers, no transparencies

Do not include crop marks or registration marks

Document resolution of 300-600 dpi Document size should be 420x297mm (A3) Max. printable area is 412x291mm

Type sized between 7 and 14 should be in registration black only

For booklets please provide single page PDF’s, no spreads

If possible, please provide a digital proof of your document 

If you are inexperienced or having difficulties with making your design print-ready, let us know. We can separate and set up your files for you.


Riso printing comes with a few imperfections of which misregistration is the most common.

Misregistration can happen when printing two or more colors. Please ensure room to allow 2-3 mm shifting during the print process for small details that rely on 100% registration.

Colour results vary, depending on what paper is used.

Large areas of color can be uneven and vary in coverage. Putting these large areas at 90%, or even 80%, instead of 100% coverage, can prevent this.

Riso ink ‘sits’ on the surface. That means they work is prone to smudging if handled a lot.

Small roller marks can be visible on your print. Rollers can leave their marks when printing large areas or multiple overlapping colors that are printed on the same page or when prints aren't given enough time to dry. Usually, these marks can be removed by gently dabbing with an eraser.

RISO or Riso Kagaku is the leading brand of digital stencil-duplicators that was born in Japan in the ’80s and is manufactured by the Riso Kagaku Corporation. Riso evolved from the mimeograph, an analog stencil-duplicator that was often used in offices. Stencil-duplicators made it possible for the common man to duplicate documents in a short time and in high quantity. Starting in the 1950s, mimeograph technology was used to self-publish literature, including chapbooks, manifestos, and zines. Gradually photocopiers, inkjet printers, and the Internet made the mimeograph obsolete but since Riso made the first automated stencil-duplicator the popularity in stencil-duplicating increased and Riso seems more popular than ever.

Riso is often compared to silkscreen printing because the ink - like silkscreen- is forced through a screen onto a paper. Analogous with silkscreen printing it is a cold process and every color is printed separately, our machine operates two drums at the same time so it can print two color layers in one print run. Riso inks are semi-transparent colors. This means colors can be mixed with each other, by layering, to create new and exciting colors. Riso is very popular in the arts because of its distinct way of printing can reproduce work in an authentic matter. It’s easier, cheaper, and faster than silkscreen but still has the authentic feel to it, for every print is unique in it’s own way.

The results of Riso printing can be amazing. The spot colours offer space for colour experimentations and overprinting. Also Riso has inks such as fluorescent and metallic gold, it has an authentic feel, is original and arty! Riso is an environmental friendly printing method. Riso uses a cold printing process that does not require heat to fix images onto a page. This helps keep down the overall energy consumption, even when printing at maximum speed. The ink from Riso is soy or Rice-bran oil based and non-toxic. The masters are made from plant fibres (banana and hemp). Riso is a highly efficient and sustainable printing method that fits a modern lifestyle with an awareness of the ecological footprint we all have.
