I'd recommend sticking with either 180 or 360 ppi if printing to an Epson printer. Every time I've tried a resolution that wasn't a multiple of 180, I've gotten jagged artifacts in the output from the resampling. The "native" resolution of the Epson inkjets is the factor here. Photoshop/Lightroom seem to do a much better job with the resampling/resizing than the Epson print drivers do. The photo-based professional printers seem to have native resolutions of either 300 or 400 DPI, depending on the exact model. I'm sure someone else can shed more light on the process for them. -Mat -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
