Verification engine

Run a render through the pre-listing gates.

Upload any image; the engine runs four checks against the Printful t-shirt spec (4500×5400, 300 DPI, sRGB, 0.125" bleed) and returns a per-gate breakdown. Holds stay in the catalog so you can fix the prompt and re-queue.

Drop in a 4500×5400 PNG/JPG/WebP — any size up to 25 MB.

The gates this engine runs

  • 01 Resolution — ≥ 4500 × 5400 px.
  • 02 DPI — ≥ 300, from EXIF or stored density.
  • 03 Color profile — sRGB ICC or EXIF ColorSpace.
  • 04 Bleed — outer 37 px band must carry ink on all four edges.

Drops are kept in-page; nothing here is uploaded to a third party. Submit to see the verdict.
