Even the lowest quality of paper produces an image that is exciting and more appealing than what we have been used to. But when the novelty wears off, and it doesn't take that long, you'll be pushing your printer to its limit to get the best possible output. I made prints on a range of media. Plain photocopier paper, special inkjet paper, and Epson's own special photo-finish paper, particularly designed for this printer. The quality of the output on different media is directly proportional to what you have to pay for the paper.
Regular paper is really only good enough for a check print.
The image is dull and flat, The colours in photorealistic images are muddy, particularly in the dark areas. Linework is fuzzy and indistinct. Inkjet paper is better and probably good enough for the majority of prints where high definition or colour quality is not so important. Linework and letter definition on inkjet paper is much better and looks very crisp. The blacks are dense and solid.
