Make it yours

The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.

Prompt

A two colour risograph print of an empty living room at night: an armchair, a standing lamp, a large houseplant and striped floorboards. Printed in fluorescent pink and blue only, overlapping into a deep violet where they cross, with visible misregistration of about two millimetres. Coarse halftone dots in the shaded areas, uneven ink coverage, roller marks, absorbent uncoated paper showing through. Flat perspective, simplified shapes, no gradients.

Tips

1Name the two inks and what they make where they overlap. That third colour is the giveaway.
2Ask for misregistration in millimetres. Vague requests come back perfectly aligned.
3Coarse halftone instead of gradients. Riso cannot blend.
