RGB (Red, Green, Blue) is an additive color model where colors are created by combining red, green, and blue light. It's the standard for digital displays and electronic devices.
CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model used in color printing. Colors are created by subtracting wavelengths from white light using ink.
The RGB to CMYK conversion follows these mathematical steps:
R' = R / 255, G' = G / 255, B' = B / 255K = 1 - max(R', G', B')C = (1 - R' - K) / (1 - K)M = (1 - G' - K) / (1 - K)Y = (1 - B' - K) / (1 - K)RGB displays can show more vibrant colors than CMYK printing can reproduce. Some bright RGB colors will appear duller when converted to CMYK. Always proof colors for critical print projects.
This conversion is essential for:
