File formats

  • Preferred: AI, PDF, SVG, PNG, PSD
  • Use vector formats for spot colours and small text
  • Flatten transparent PNGs before upload

Colour profile

  • Design in RGB or CMYK – we convert to our calibrated DTF profile
  • Spot colours should be named with Pantone references where available
  • Avoid overprint settings unless specifically required

Resolution & detail

  • 300 DPI at final size
  • Minimum line thickness: 0.35 mm
  • Minimum text height: 2.5 mm
  • Keep raster artwork sharp with uncompressed PNG or PSD

Bleed & underbase

  • Add 1 mm bleed on full-coverage graphics
  • Use transparent backgrounds and let the builder create the cut line
  • White underbase is automatic – adjust choke from 0 to 1 mm as needed

Knockouts

  • Knockout garment colour where you want the fabric to show through
  • Use vector masks for the cleanest edges
  • Layer effects are flattened during RIP, so expand if you need precision

White ink handling

  • Pure white (RGB 255,255,255) generates white ink
  • Transparencies under 20% convert to a halftone for softer blends
  • For glitter or foil top layers, speak to the team before ordering
