Question

What black color values should I use for printing black-only business cards?

Answer

For a deep, solid black on printed cards, do not rely on 100% K alone. Black ink by itself often prints as a flat, slightly gray tone, so a rich black built from all four inks looks far darker.

ValueCMYK
Rich black (recommended)504040100
Flat black (avoid for large areas)000100
  • Use rich black for large fills and backgrounds where depth matters.
  • Keep small body text at 100% K only, so fine type stays sharp and avoids registration fuzz.

Combining cyan, magenta, and yellow under the black is what gives large black areas their true depth.
