  3. Click “Run anyway”

PrepressGate runs 100% locally. No data leaves your machine.

Full check. Real files. No limits.

The desktop version checks your actual production files — vector, raster, and embroidery.

  • AI, EPS, PDF, SVG, PSD, PNG, JPG, TIFF, DST, PES, EXP
  • Detects spot colors, resolution, transparency, ink coverage
  • No file upload — runs locally
  • No size limits
  • Print-method-aware checks (offset, screen, DTF, embroidery, sim-process)

AI/EPS checks require Adobe Illustrator 2022 or later. Other formats work standalone.
