Question

What does the 4/0 and 4/1 designation mean for printing?

Answer

These numbers describe how many ink colors print on each side of a piece. The first number is the front, the second is the back, and 4 stands for full-color CMYK while 0 means nothing prints on that side.

NotationMeaning
4/0Full color on the front, blank back (single-sided)
4/1Full color on the front, one ink color (usually black) on the back
4/4Full color on both the front and the back
  • Pick the option that matches whether you need one side or both sides printed.
  • Upload artwork for every printed side the option calls for.
  • If both sides are full color, choose the 4/4 option and supply front and back files.

Matching the notation to your artwork makes sure each side prints the way you intend.
