Cyan/Magenta/Yellow/Black Channels Separation
Answers to Questions
How to separate CMYK values of an image?
The image will be analyzed in printing color components. There are four main colors when printing: Cyan, Magenta, Yellow and Black.
The result will be returned in grayscale for each color. Between 0 for no color and 1 for pure color.
Example: The dCode logo do not have any Cyan (light blue)
Example: For majenta the C is kightly visible
Example: The dominant yellow is very visible
Example: The black draws the contours of the image
In order to accelerate the calculation of channel separation, the image will be resized if it is too large.
Why 'K' in CMYK?
In English, CMYK (instead of CMYB) stands for Cyan, Magenta, Yellow and Black. To not use the B letter for Black (as B stands for Blue), term Key is preferred (the black component is often the most important when printing : the key)
