Poster & Large-Format Illustrations
Large format is where raster generation runs out of road. A 4K image is roughly 13 inches wide at print resolution — enough for a flyer, not for an A1 poster. Vector has no such ceiling: the same file that fills a business card fills a billboard, and the only thing that changes is how far away people stand.
Generate the composition as a vector illustration, then treat scale deliberately: elements that look balanced on screen often read as cluttered at A2, because your eye takes in the whole poster at once. Simplify in the studio, push contrast, and check the design at thumbnail size — if it does not read at 5% zoom, it will not read across a room. Export SVG for the print vendor, and a high-resolution PNG if their RIP prefers raster.
Large-format specs
| Resolution | Vector has none to worry about — an SVG at A5 and at A0 is the same file |
|---|---|
| Viewing distance | Poster detail should read from 2–3 metres; thumbnail-test the composition |
| Color | Ask your printer whether they want RGB or a CMYK conversion; flat vector fills convert predictably |
| Bleed | Extend background shapes 3mm past the trim on every edge |
Styles that fit
Each of these presets is tuned for full-scene illustration, not icon glyphs. Pick one to open the generator with it already selected — suggested canvas for this job is 3:4.
Example prompts
Describe the whole set in one prompt — generating the scenes together is what keeps them looking like one family.
How the illustration flow works
- 1
Pick the job
Open the Illustrations tab in the generator and choose the use case — poster & large-format illustrations maps to a tuned prompt template rather than a blank box.
- 2
Describe the scene
Give the product context and, optionally, the specific scene. Suggestions appear as you type, and you can attach up to three of your own illustrations as style references.
- 3
Review before you commit
Generation returns a preview first. Keep the ones that work, generate more into the same batch, and only then import — credits are spent on generation, not on browsing.
- 4
Vectorize and refine
Accepted scenes are traced to real SVG paths and land in a project. Open any one in the studio to clean nodes, recolor fills, or simplify paths.
- 5
Expand later, still matching
When you need scene number nine, expand the same project. Your existing illustrations become the style reference, so the new ones match instead of drifting.
Frequently asked questions
Can AI-generated art be printed at poster size?+
Raster output cannot go much beyond about 13 inches at print quality. Vector output can go to any size, which is why Icora traces generated scenes to real SVG paths rather than handing you a fixed-resolution image.
Do printers accept SVG?+
Many do, and those that prefer PDF or EPS can convert from SVG without quality loss. If a shop insists on raster, export a high-resolution PNG from the vector source at the exact print dimensions.
