Quick tips:

  • Always convert to CMYK before uploading files – this allows tighter control over your colors and images.
  • Obtain rich blacks with this build: 30% Cyan (C), 30% Magenta (M), 30% Yellow (Y) and 100% Black (K). Finish it off with a 0.5-point stroke of 100% Black (K) for best quality.
  • Submit graphics and text designs (any non-photographic content) as vector-based PDFs or Adobe Illustrator (.ai) files to ensure lines and text are crisp.
  • All text should be at least 8 point and bold colors, made up of one or two inks only (C, M, Y or K).
  • Include at least a 0.25-inch bleed when graphics extend past die-line.
  • Lines in a solid or dark color should be no thinner than 1 point.
  • Make sure all fonts are embedded or outlined.
  • When possible, save your designs using the Adobe PDF/X-1a precept.
