QTR-Quadtone RIP

Grayscale ICC printing means you select a Create-ICC built ICC profile in PrintTool (OS X only), select perceptual mode, hit print, select your curve, and print. The Create-ICC profile pulls the shadows down slightly before the image hits the .quad and prints. Many people really like this way of printing.

PiezoDN will utilize CreateICC profiles for this final dark pull-down. It really seems to work great when dealing with Alt-Process printing that utilize wildly different dMax values (anywhere between light reflection of 3% to 30% in the blackest patch). However, if you are working on a PC and you have the PiezoDN curves, you will still be able to print VERY linear negatives and you will also still be able to linearize those .quad negative curves with the Quad-Linearizer droplet. By no means will the PiezoDN system not work on the PC, however, you may find that the screen-to-print match is not always as exact as you would wish with some alt-process methods of printing utilizing only the linear .quad and a GrayGamma 2.2 image. 

That said, OS X is free now, and it can be installed in VMware. It’s basically 70 bucks to get OS X running virtually inside of a Windows machine if one wants to run Print-Tool but they only have a PC.
