I am considering having some of my digital color files printed at Costco. They have a service for a 12X18" print on Fuji Crystal Clear paper for $2.99, which is probably as inexpensive as I can print color on my Epson 3800. However, I can only upload .jpeg files. Will changing the file from .psd to .jpeg and immediately printing from it result in much loss of image quality?
