The prompt

{subject}, in the style of a flat cut-paper screenprint poster, rendered as bold flat colour-shapes with hard clean knife-cut edges and almost no gradient on a pure bright white ground, selective full-neon spot-colour fills standing in for screen-print spot colours, crisp white knockout shapes carving highlights and detail out as negative space, {palette}, festival brightness from saturated flat fills against open white, luminous and atmospheric, slight registration overlap between layers, full-frame composition

Slot recipes

How the prompt changes for each kind of picture.

  • Hero: Full-bleed wide composition; one dominant subject built from large flat neon spot-colour shapes against generous pure-white ground, white knockout carving the key detail; bright festival light, atmospheric not flat-loud; no text.
  • Spot: Single subject as a compact flat cut-paper cluster, 2-3 neon spot colours plus white knockout, white ground around it for breathing room.
  • Portrait: Subject reduced to bold flat colour planes with hard edges; white knockout for facial highlights and eyes; one neon accent dominates, white ground.
  • Pattern: Repeatable strung-module composition (bunting, scales, streamers) of flat neon triangles or shapes with white knockout gaps, even rhythm across the frame on white.
  • Thumbnail: Saturated single subject, full neon fills, hard edges, white ground; reads instantly at small size.

Guidance

Do

  • Build every subject from bold flat colour-shapes with hard, clean knife-cut edges.
  • Keep the ground pure bright white; let it breathe between shapes.
  • Use selective full-neon spot-colour fills like screen-print spot inks.
  • Carve detail with crisp white knockout shapes as negative space, not with shading.
  • Allow slight registration overlap between colour layers for an authentic print feel.
  • Keep festival brightness atmospheric and luminous, never a garish flat-loud wall.

Don’t

  • No gradients, airbrush, or soft painterly shading.
  • No muddy, desaturated, or pastel washes.
  • No grey or beige neutrals; neutrals are pure white and pure black only.
  • No photographic realism or childish kawaii cartoon styling.
  • No drop shadows, bevels, or 3D rendering.

In the lineage of

  • Screenprint / serigraphy spot-colour printing, tradition. Flat opaque spot inks and registration overlap; white shapes reversed (knocked out) of solid colour.
  • Mid-century cut-paper collage (Henri Matisse gouaches decoupes), movement. Bold flat shapes with hard scissor-cut edges as the primary drawing language.
  • Kirie Japanese paper-cutting, tradition. Detail carved as negative space rather than rendered with tone.
  • Plakatstil / poster reductionism, movement. Subject reduced to a few flat colour planes on open ground for instant legibility.

A generated style is an aggregate of many influences. Credit goes to the artists and traditions it draws on; it is not a claim of authorship.
