Riso: fluorescent pink and blue ink dithered onto cream paper
Riso reduces an image to the inks of a small-press print shop: fluorescent pink, a medium blue, black, and cream paper showing through as the lightest tone. Stucki error diffusion decides where each ink goes, so warm areas drift pink, shadows go blue-black and highlights are left as bare paper. Pixel size 3 keeps the dots visible like a coarse print screen, and Grain at 20 adds the uneven ink coverage that makes risograph posters feel handmade.
Make it yours
Simplify it into a poster
Lower Dither strength from 100 to about 40 and the inks stop mixing. They settle into flat pink, blue and black zones, closer to a cut-paper gig poster than to a photograph.
Let more paper show
Bright images print better in this look. Raise Brightness to 15 or Gamma to about 130 so more of the frame falls to cream paper, which gives the pink and blue room to stand out.
FAQ
Can I change the ink colors in the Riso preset?
The Riso palette itself is fixed to pink, blue, black and cream. For custom inks, switch Palette to Duotone and set Dark color and Light color to your own pair, keeping Stucki and Grain for the print feel. You lose the third ink but gain exact brand colors.
