Re: Gum Separations Using Indexed Color

[Philippe Berger <mineurdecharbon@skynet.be>]

Only for Yellow, Magenta and Cyan but very different of the separation of 
layers by Photoshop
My software use the Filters Red, Green and Blue and after apply the curve 
for the good separation of color to btain the negatives for the cyan, 
magenta and yellow gum

Are your separations for complentary colors only (for example, yellow,
magenta and cyan) or also for not-complementary ones (I like to call them
"oblique colors" as opposed to "orthogonal colors"), like for example brown,
turquoise, brick-red and green, or any other combination of 3 to n colors?
