So, it sounds like you send the full-rez image to the printer 
regardless of what size you're printing at; but how do you deal with
sharpening ?   That really needs to be dependent on print-size, as I
understand it.  So do you adjust the radius of the USM depending
upon the resolution (pixels per inch) ?
