Digital BW, The Print

If I were a RIP designer who could work from scratch with all 
the input over the years of lists like this I would look for a 
printer calibration method that would consider the native 
behaviour of the printer and what realistic standard was 
possible with that behaviour plus at the same time check what 
fitted color management on top of that standard best. If all 
the perceptual curves of different papers + BPC etc result in 
a space that isn't a too complex shape it must be possible to 
find the average 3D curve within that shape and use that as 
the calibration standard. Building the profiles on that should 
theoretically allow a better fit from the native behaviour of 
the printer up to the color management.

To give an analogy, if you have a metal cloth hanger with a 
shape you like to alter you could first start to make the wire 
frame straight and after that bend it to the shape you want. 
Measuring is easier then. You could also look whether the 
original shape has elements that come close to the desired 
shape and just alter the differences. Less bending needed but 
a more complex shape model to build on. Depends on the 
original shape and the desired shape which method is best.

If I were a RIP designer who had a RIP working as nice as QTR 
I would take care not to go on paths unknown. And Roy may even 
know that those paths are actually dead ends. For me it is an 
abstract model, Roy will now the numbers.
