Hi anyone,
I am in need for a special need. I received a RVB image that must be used as a background for a published leaflet.
So i coverted it into CMYK mode and the conversion created rich blacks with high CMYK values such as 90/90/90/100. I would like to reduce the ratios of CM & Y channels in the darks areas so the rates of black zones are close to something like 60/60/60/100 WITHOUT and that is the most important desaturing so much medium and lights areas of the pictures. I just want to reduce CM & Y in the dark areas.
I tried using the black channel as an aplha channel to reduce the amount of CM & y (filling white 20% opacity in these channels) and sure i get what i want mathematically but the colour result is not so good. Using curves is not a good issue as well.
What could you advice to me in order to get a proper result. I did a capture, you can look at it here :
