I'm sure that's not the correct term.
I guess my question is once photoshop prints utilizing the full 16bits should the targets be reprinted and measured? I use Bill Atkinsons targets still and they are 16bit. If I convert the target to 8bit, the histogram changes, dramatically in a few levels, so my weak logical thinking is that a similar change occurs when printing the target. Once photoshop sends full 16bit information, perhaps that change won't occur, resulting in some changes to the target (subtle I"m sure).
I've heard discussion that those using the Canon export module for printing with 16bits should build a separate profile, but I"m not sure if that recommendation is due to it being 16bit, or just the fact that it uses the module vs the Canon/OS driver.
