How To Print?

We are always happy to try new stock at Jumbo and if you have a specific paper in mind we are always happy for you to bring your own stock, or we can look at getting it in for you.
The machine reliably will take any (uncoated) paper from 80-250gsm.


We generally like to use high quality recycled papers, some of our go tos are Acroprint Milk, Woodstock, Cyclus Offset and Munken lynx.
These papers absorb risograph ink well, while still lending their self to the tactile, vibrant feel of riso. Please get in contact to see what papers we currently have in stock, as it varies in stock time to time.

When sending us your artwork, please mock it up on an A3 document at 300-600dpi. We would suggest sending us a Photoshop file with each color in a separate named layer. Each color turned into grey scale and a layer with a color proof.

We also accept jpegs or PDFs in separate grey scale files. Please name the files appropriately and provide a full color proof.

If you're looking to print a full color image or an image that isn’t separated, it is possible to achieve this by using CMYK separation through channels. We can help prepare files at a small fee.

We would suggest, when overlaying colours or using a heavy coverage of ink, lowering the opacity of your artwork to a percentage of 75%. This said, line work always looks best if it’s vector and 100% black.

Try not to make the top part and middle of your print very inky, as it can be more susceptible to roller marks. Especially if it’s on the first pass of printing

We print anything on uncoated papers up to A3 (297 x 420 mm) with a maximum printable area of 289 x 409 mm. We also suggest adding a 5 mm bleed to all artwork, which is being cut down.
