Frequently Asked Questions

What does the 'K' in CMYK stand for?

'K' stands for 'Key' plate, which in commercial 4-color printing is printed in black ink to add depth, contrast, and crisp detail.

Can all RGB colors be printed in CMYK?

No, vivid saturated RGB colors (like bright neon green or intense electric blue) fall outside the standard CMYK gamut and will print slightly more muted.
