QTR-Quadtone RIP

Hi Louis,

The answer is that it's the same as always -- images are upsampled to 720ppi
before dithering.  But in general I don't think its something you need to worry
about.  I might use 720ppi test images for specific testing but for ordinary
printing I just use whatever I have.  It's nice to have at least
360ppi for sharp
images but if its 311, 435, 597 or whatever I just use that.
