Screenprint Overprint
Opaque ink laid thick through mesh, one flat colour per pass, building depth by overlap.
What it does
Screenprinting lays a far heavier ink film than lithography, so colours are opaque and can print light on dark. There is no continuous tone: every colour is a separate flat pass through a separate screen, and the design must be built in layers from the outset. Warhol's Marilyn series and the gig-poster tradition both depend on this. Registration is achieved by eye against pins, so a slight offset is normal, and the ink edge is very slightly raised and visible in raking light.
The prompt
Replace [Subject] with what you are shooting. Everything else is deliberate: the gear, stock and lighting are what push a generator towards this look.
