Hi, this is my first post here. In earlier posts, members stated that the Epson Ultrachrome printers upscale lower resolution files to 360 ppi. So the question that occurs to me is how good a job of interpolation does the printer's driver do? Maybe I'm better off doing my own interpolation using Photozoom Pro, which seems to do a very good job. Recently I had an old digital image I wanted to print large, and I upsampled it from 117 ppi to either 180 or 240 (I'm too lazy to look for the file) before printing it on my Epson 7600. Would I have done better to go all the way to 360? Or are they saying that if I had sent it to the printer at 117, the driver would have interpolated it up to 360 and it would have looked just as good as the file I iterpolated up to 180 or 240? Thanks for your help with this; hope it's not too confusing.
