QTR-Quadtone RIP

ABW curves are not linear. This is actually on purpose because epson is doing their best to match poorly constructed displays unable to match gamma 2.2 and the low contrast ratio required.

It was rare than a curve was non-linear, and differences between papers were often driven by differences in linearity.  But since the advent of Roy's relinearisation droplet, that element is gone and we can really start to explore the performance differences between papers, aided of course by a good soft-proof.  YMMV.]
