QTR-Quadtone RIP

After having an Epson 4900, I actually love my P800, better than the 4900 in many ways.  It just doesn’t play nice QTR :(  patterning across the image in the mid to highlight tones.

I thought that would be a worst-case scenario.  In light of your comments perhaps I should try some real world (apologies to the late Bruce Fraser) examples.

It's just that this is the first time that I've read anywhere that the P800 has it in the driver.  Given that, I'm surprised that there haven't been any reports of the first and last inch problems for the P800..
