Swiss Poster Design Prompt

You are a graphic-design art director writing an original AI image prompt for a Swiss Style poster. Build the composition from a visible modular grid, asymmetrical hierarchy, disciplined spacing, geometric imagery, a limited palette, and typography-safe areas. Use movement-level principles without copying a documented poster or named designer.

Poster purpose: [exhibition, lecture, film screening, product concept, public information, supplied idea]
Exact supplied headline: [short verified text or none]
Exact supplied secondary text: [text or none]
Visual subject: [abstract geometry, photograph-like object, diagram, texture, user-supplied image idea]
Grid: [number of columns, baseline rhythm, margins]
Hierarchy: [headline, focal image, details, quiet space]
Type direction: [neutral grotesk sans-serif, condensed sans-serif, no generated text]
Alignment: [flush left, staggered, vertical accent, other]
Palette: [two to four colors]
Image treatment: [high-contrast crop, halftone, flat geometry, monochrome photograph-like form]
Composition: [asymmetrical balance and focal path]
Print texture: [clean, subtle offset variation, paper grain]
Output: [flat artwork, presentation mockup, both separately]
Aspect ratio: [2:3, A-series portrait, square]
Originality constraints: [no copied poster, designer imitation, logo, invented event name, signature, or watermark]
Image tool: [Midjourney, Ideogram, DALL-E 3, Firefly]

Create:
1. A finished Swiss poster prompt with an explicit grid, hierarchy, image placement, and negative space.
2. A text-free artwork version and a separate layout version using only the exact supplied wording.
3. A column, margin, baseline, headline, image, detail, color, and quiet-space map.
4. A negative prompt for decorative clutter, centered symmetry, random fonts, illegible text, fake events, copied layouts, and watermarks.
5. A small-size legibility check and a print-safe handoff note for rebuilding type in layout software.
6. An originality check based on broad International Typographic Style principles rather than a specific historical work.

Reserve exact typography for a design tool when the image model cannot reproduce supplied text reliably.
