CMYK is a color model using four primary colors: cyan (Cyan), magenta (Magenta), yellow (Yellow) and black (Key/Black). It is used mainly in printing and printing to create color images on printing machines.
- Cyan (Cyan): A shade of blue used to reproduce the blue spectrum.
- Magenta (Magenta): A shade of red, used to reproduce the red spectrum.
- Yellow (Yellow): A shade of yellow, used to reproduce the yellow and green spectra.
- Black (Key/Black): Black color added to improve depth and contrast, and to reduce ink consumption.
CMYK is used in the printing of almost everything (brochures, posters, packaging, magazines, books, etc.), where the accuracy of color reproduction is important. The number of possible colors in the CMYK system is limited by the number of possible combinations of these four primary colors. There are 104,060,401 colors in the CMYK system. This is many times more than HEX or RGB can transmit.
Is there transparency in the CMYK model?
The original CMYK color model used in printing and printing does not have an alpha channel to determine transparency. Each of the four color channels (cyan, magenta, yellow, black) is determined by its own saturation percentage from 0% to 100%, and they are combined to create the final color.
However, there are advanced variants of the CMYK model that support an alpha channel to determine transparency. Formats such as CMYKA or CMYK + A can be used in some graphics programs that support transparency.
