CMYK value means the value of printing four colors.
CMYK refers to the printing four-color mode, which is a color matching mode used in color printing. By using the principle of mixing three primary colors of color materials and adding black ink, a total of four colors are mixed and superimposed to form the so-called "full-color printing". Each CMYK four-colour ink can be used with values from 0 to 100%. A printing ink that specifies the brightest color has a lower percentage of color and a higher percentage of color for darker colors. For example, bright red may contain 2% cyan, 93% magenta, 90% yellow, and 0% black.
The four standard colours are:
C: Cyan= Cyan, also known as sky blue or azure blue
M: Magenta= Magenta
Y: Yellow= Yellow
K: blacK= blacK
Thousands of other colors can usually be reproduced from these four colors in printing. The CMYK model focuses on printing media, that is, based on the light absorption/reflection properties of ink. The color seen by the eye is actually the color of the object absorbing a specific frequency of light in white light and reflecting the rest of the light.
CMYK is a must for any project that is going to be physically printed onto any substrate.
For example:
Cardboard banner
PVC banner
