QTR-Quadtone RIP

Hi Remko,

When the curves are generated initially, the density in the image always rises too fast so you get compressed shadows. The linearisation procedure uses measurements from a spectro like the i1 Pro to compensate for this non-linearity. If you look at the plots of L* you will see that after linearisation they rise very uniformly right up to step 100. There are a couple of good documents on the QTR site that explain the processes.

Incidentally, having looked at my step wedges again, I am inclined to change the "Warm" to "Sepia"! It really does look very warm.....
