Overview of colour theory using cyan, magenta and yellow filter systems
Colour printing rules:
Too magenta - add magenta
Too yellow - add yellow
Too cyan - subtract yellow and magenta in equal parts
Too Red - add yellow and magenta in equal parts
Too Green - subtract magenta
Too Blue – subtract yellow
When adding filtration, the expoure time needs to be adjusted by +/-10% to compensate for filter density per 10 points of filtration.
