I've seen sufficiently many reports of people seeing improvements in Epson inkjet output at ppi values up to 720 that I don't consider 240 to be optimum. It's more like "minimum professional level" or something -- despite the fact that I've passed off 150 ppi Epson prints to professionals on occasion (it all depends on the subject, as usual). As I say, a small detail. -- David Dyer-Bennet, dd-b@dd-b.net / http://www.dd-b.net/dd-b/ John Dyer-Bennet 1915-2002 Memorial Site http://john.dyer-bennet.net Dragaera mailing lists, see http://dragaera.info
