RGB to CMYK

This converter can convert RGB color model to CMYK color model very quickly, CMYK is also called the print color model. The name suggests is used for printing. CMYK and RGB are two different color models, and the two have fixed formulas that can convert each other. Enter the values for colors of RGB, then click the Convert button you can get the CMYK values and hex value. CMYK to RGB

Knowledge of converter

The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black).

The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

How to convert RGB color to CMYK color

Since RGB and CMYK spaces are both device-dependent spaces, there is no simple or general conversion formula that converts between them. Conversions are generally done through color management systems, using color profiles that describe the spaces being converted. Nevertheless, the conversions cannot be exact, particularly where these spaces have different gamuts.

R' = R/255
G' = G/255
B' = B/255

Then we use the following formula to calculate:

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