Question

What file format and color mode should I use for printing?

Answer

A print-ready PDF is the standard format, and artwork should be built in CMYK color mode so colors reproduce accurately.

File formatPrint-quality PDF
Color modeCMYK
ImagesCMYK, not RGB
Bleed1/8" (0.125") on each side

If your file arrives in RGB or Pantone, it is converted to CMYK during processing, which can shift some colors. Converting to CMYK yourself before submitting gives you control over how those colors land.

File arrives inWhat happens
CMYKPrints as built
RGBConverted to CMYK; bright colors can print duller
PantoneConverted to the closest CMYK mix; some shades shift
  • If a color profile is required, use SWOP (U.S. Web Coated); if your software allows it, choose no color profile.
  • Bright blues, greens and oranges shift most when RGB is converted, so review colors after converting.
  • Keep the same CMYK values across reorders so pieces match from batch to batch.
