How to get the best results from Riso printing

The Risograph printing process has unique character and slight imperfections. These imperfections include:

Smudging

Risograph ink is made from a combination of environmentally friendly soy oil, water and pigment, the prints are reminiscent of newspaper ink and with enough effort it is possible to smudge the ink. We can assist you with designing a project that is less prone to smudging. We offer top-coating services to prevent smudging, a great addition to business cards, book covers and other items that need extra durability.

Uneven coverage

Large flat areas of solid ink coverage are likely to show some slight variations. We can assist you in choosing the right ink and tone for your project to get the best gradient and finished effect.

Registration

Riso is similar to screen printing, each ink color is layered on separately. A single piece of paper will run through our machines several times for multi-color projects and the overlap of colors can be irregular. We use trapping and can offer you other techniques to lesson registration issues.

Tire marks

When a paper is fed through the machine multiple times and it is heavily inked, the paper feeder rollers may leave tire marks on the page. We try to avoid this issue by having the heaviest inked color printed last.
