Does anyone create custom grey scale profiles for Quad Tone Rip.
I personally use the X-Rite Color Munki for profile creating and to be honest the workflow for Qtr is a little on the clunky side.
Some time ago you could actually use custom profiles with the ABW driver but that has all changes now. The ABW is essentially a black box, you can feed it a colour image and it will give you a black and white image, whether it matches your vision is another question.
If you want full control...
