[Lcms-user] Re: Mixing Lab color

Marti,

Concerning the mixing color a question about profile transform :

To convert from Lab to CMYK I do :
  Lab2CMYKTransform:= cmsCreateTransform(hLabProfile,
                TYPE_Lab_16,
                hCMYKProfile,
                TYPE_CMYK_16,
                INTENT_PERCEPTUAL,0);

to convert the mixing result to RGB I do

CMYK2DisplayTransform:= cmsCreateTransform(hCMYKProfile,
                TYPE_CMYK_16,
                hDisplayProfile,
                TYPE_BGR_8,
                RenderIntent,0);

where here RenderIntent is a variable that the user can set for using
Saturation, perceptual....

So for the CMYK to RGB no problem.
But about the Lab to CMYK what should I use? (here I use INTENT_PERCEPTUAL,
but I don't know if I should also use RenderIntent)

thanks
