CMYK Conversion Formula

To convert an RGB color (Red, Green, Blue) to CMYK (Cyan, Magenta, Yellow, Key/Black), follow these steps:

1. Normalize RGB values:

If the RGB values are in the range 0–255, convert them to the range 0–1:

R′= R/255 , G′= G/255, B′= B/255

2. Calculate the Key (Black) component:

K = 1 − max(R′, G′, B′)

3. Calculate the Cyan, Magenta, and Yellow values:

C=(1-R'-K) / (1-K) , M=(1-G'-K) / (1-K) , Y=(1-B'-K) / (1-K)

If K=1, set C=M=Y=0 to avoid division by zero.
