Float ink on a wet bath; it bleeds, mixes, and never quite dries. Slide toward 装 and the same engine holds still — fixes, flattens, and prints itself in halftone dots. Time is still until you play the bleed; sequence is material — each pass lands on what the last one left.
A picture, cut into your inks on the screen — palette + grid, the quantization — laid down wet so the bleed dissolves it back. Your inks are the basis; colours they can't mix don't survive.
The screen strengthens automatically toward 装. A water screen lays the riso pattern as repulsion — set inks get pushed into the gaps.
Step the bleed by hand, or play it. Time only moves here.
Background is a viewing choice — it isn't written into .urumizuri or .bakezuri. .bakezuri stores the whole process (passes + bleeds), seedless: every performance bleeds differently.
