Frequently asked questions
- Why is CMYK used for printing?
- Printers use subtractive color mixing — inks absorb light. CMYK inks combine to produce a wide range of colors on paper, unlike RGB which adds light.
- Is RGB-to-CMYK conversion exact?
- Not always. RGB and CMYK have different color gamuts. Some vivid screen colors cannot be reproduced in print.
