Class Details

[line 43]
CMYK is a subtractive colormodel used in printing.

Colors are represented using Cyan, Magenta, Yellow, and blacK components (the K actually stands for key plate which is typically printed in black).

The conversions done by this class are very crude. The results should only be considered as a rough approximation.
