QTR-Quadtone RIP

I have produced a .quad file that lays down black, magenta and yellow ink equally and in a linear pattern until my desired dmax is reached, this is for producing digital negatives. They print very nicely but need a little tweaking in the highlights. This is quite an undertaking, it seems and to do it myself would require a program in python or something similar. (unless you do it with a curves in an image editing program, which is what I am doing at present)

Is it possible to produce a .qidf file that can mimic the linear ink curves I am producing, so that the linearisation tab on the windows QTR interface could be used instead? Or perhaps so that output from an i1 could be used directly to linearise the ink curves?
