Basically, the stuff people have the most problem with is all the work with the ink descriptor files, generating correction curves, and figuring out how to use the Linearize line....
So, I took the ink descriptor file and curve creation process out of the picture completely. All you need to do is set your initial blocking density with the K channel (there is a lot of flexibility because off the additional overlap and 5 underlying color inks) and export the starter quad curves. Then install the exported .quad file, print 21-step target and enter the measurements and watch the quad curves automatically linearize.
The real magic is in the linearization process though. There is a lot being done to the measurements behind the scenes and then through the automatic correction curve process that really make all this work. I took the concepts I introduced a few years ago with my QuadLin service—like reshaping the quad curves in real time with input and output points for the shadows, midtones, highlights—and refined them to where perfect linearization can be done with only 21-steps. This whole thing is the product of several years trying every digital negative method there is and setting out to make my own. After a year of tinkering and tweaking my negative linearization tools I think it will solve all the problems that have frustrated people ever since people first started down this QTR negative route.
