# How do I print rich black colors without unwanted casts?

Deep, neutral blacks avoid a blue or brown cast when built correctly. A true rich black is built from a CMYK mix rather than 100% black alone, and reviewing a physical proof is the surest way to confirm the tone before your full run. Build rich black as a CMYK mix instead of K only, so the black reads dense and neutral. Request a physical proof to check the black in hand under good light. Ask your printer about file preparation and the material or press specs for your job. Keep fine text in solid black only, since heavy multi-ink blacks can look muddy at small sizes.

Rich black prints neutral when built as a CMYK mix rather than 100% black alone, checked on a physical proof, with fine text kept in solid black only.
