Are you sure of this? Possibly true with an "additive" (RGB) system - but most dichroic heads in use now are "subtractive" ... (CYM... well OK .. K).

I have never been able to balance out using pure magenta/ red filtration in 15 years of color printing - in either Color Negative (EP2/ RA4) or Direct Positive (R3/3000, P3/30) printing.
