We also operate as a RISO Printing Studio, we own two RISO Duplicators RZ370 & RZ570. Below you'll find some helpful information we put together for you to better understand how does this technique works. Contact us with any questions or if you need a quote.
What is RISO Printing?
Riso is an environmentally friendly and cost effective printer, which uses standardised ink colours to produce unique outcomes. Each stencil (master) unlike offset printing only takes a single print for the screen to be fully inked and ready to print. The Riso generates a minimal amount of waste and we try to recover all the bad prints to create other types of design experiences.
How does it work?
Riso works either digitally (from the PC) or via scanner that’s attached to the Riso body. The master is created by burning the image onto the master roll inside the printer creating a stencil that wraps around the ink drum and transfers the image into the paper of our choosing, as many times that we want at a high speed.
Why use RISO?
If you know silk screen printing, you’ll find that the aesthetics are very similar, but Riso is an affordable option and it’s a much quicker process. Riso has standardised ink colours that can be overlaid to create colour mixes and build up new colour layers outside of this spectrum.
Riso prints one colour at time. So, your final print files should be separated into individual grayscale images for each colour that is to be printed. Again, it’s similar to preparing files for screen printing. 100% black in each colour layer, will print out as 100% of whichever color you are printing. 90% black will print as 90% and so on. All solid shapes, type and images should be set to Registration Black (from 10% to 100% opacity).
We prefer to receive the files in PDF. Fonts can’t be smaller than 6pt. and lines 0,25pt.
Due to the quirks of Riso it creates small mistakes, there's no point in trying to make it look perfect, embracing it it’s part of the fun.
