Frequently Asked Questions
Why do printed colors look different from screen?▾
Screens emit light (RGB), while print absorbs light (CMYK). The CMYK gamut is smaller, so vibrant screen colors often appear duller in print. Always do a test print for critical color work.
What is the K in CMYK?▾
K stands for Key, referring to the black ink plate. Using a separate black ink produces sharper text and richer blacks than mixing C+M+Y, which would create a muddy dark brown.
