RISO INK CAN BE LAYERED TO CREATE NEW COLOURS AND NUANCES
The ink is translucent meaning that colours can be overlayed to create unique tones and new colours! Just like with painting you can layer a yellow ink on top of a blue and create green. With different opacities you can create many different greens, blues and yellows just by printing with two colours: yellow and blue. In this way you are given a third colour and so many nuances for free.
Hot tip: Color overlay can be simulated by using multiply layer modes in Photoshop, Illustrator etc.
RISOGRAPHS PRINT BETWEEN 10-100% & IT READS IN GREYSCALE
The Riso prints on a gradient of 10 to 100% coverage and all files are sent to the printer in grayscale. Playing with different opacities works great for Riso. We don’t recommend 100% coverage on large areas as it will be difficult for the paper to absorb all the ink = smudging, long drying time and the paper might get stuck on the drum when printing.
RISO INKS ARE MADE FROM VEGETABLE OIL
The Riso inks are non-toxic and rice - and soy oil based. They require a bit of time to dry. The ink actually sits on top of the paper, which is also why there’s a chance of smudging if you handle the print too much (like newspaper). This won’t be an issue if you handle your prints with a bit of care.
NB! You can use a rubber to remove tire marks or unwanted smudges on prints.
MISREGISTRATION IS PART OF IT
Because the Riso was initially made for offices and not for art prints it will always come with a chance of irregularity and imperfection. This is a part of the appeal for us! Every print is unique. Riso in this way almost behaves human, these quirks are what makes every print interesting. This also means that smudging, uneven coverage when printing large areas of solid ink, (mis)registration meaning irregular overlap of colors, and tire marks are not issues, but something to keep in mind as part of the Riso’s charm. The idea of riso printing is to create a finished product that seems hand-printed - not mass produced!
AVOID WHITE LINES ON YOUR PRINT
If you want to avoid white lines in your design from misregistration you can trap your layers in Illustrator. Simply make your object a bit bigger than the shape you have cut it out of. However, you can also think of the white lines as part of your design and avoid using trapping.
