File Prep & Proofs

Resolution guidelines, color profiles (CMYK vs RGB), bleeds, and soft proofs.

We strongly recommend print-ready PDF files (PDF/X-1a:2001 or PDF/X-4). We also accept high-resolution vector files (.AI, .EPS) with fonts converted to outlines, as well as flattened high-res TIFF or PSD files at 300+ DPI.

All files should be submitted in CMYK color mode with the GRACoL 2006 or FOGRA39 profile. If you submit RGB or Pantone spot color files without instructions, our automated prepress RIP will convert them to CMYK, which may cause minor color shifts in ultra-vibrant tones.

Please include an industry-standard 0.125 inches (1/8 inch or 3mm) bleed on all four sides of your artwork. Keep critical text and logos at least 0.125 inches inside the trim line to ensure safe cutting margins.

Always. Every print job includes a free digital PDF soft proof highlighting trim and bleed boundaries. Production begins only after you provide written electronic sign-off. Hard-copy wet proofs are also available upon request for color-critical contracts.
