Run the tests yourself and let us know. When I stopped checking on the literature of new Epsons, the latest Photo versions would not require 360 dpi ( neither 300 dpi for that matter)and reports stated that the Driver would "dump" the extra resolution to just accomodate to it�s needs( the additional resolution just taking you more time to get the same print as the "dumping time" ( the spooling) increased with the extra, unnecesary resolution in the original file. As I say, I can�t talk about the new ultrachromes etc, but if I were you , I would be prepared for a nice surprise!. On the issue of interpolation, there is a very old report( back from last century, like in 1998) that discussed the issue of the "elasticity" of digital files as a real , formal characteristic of such files , providing room for interpolation as a regular procedure, being much more effective in files from cameras than from film scans. The link to the pdf document should be in the archives. Many recent tests have also confirmed the last century tests and have proven that you can even go as low as 1.6 times the LPI, this is 300/1.6=187dpi ( which would explain why Canon has set it's native resolution in it's camera files at 180 dpi) to go for Printing ( please recall I NEVER mean Epson printing, I always mean the real one). Should this be the case, then Epson Priniting can also go with either less resolution than regularly used or just be able to provide bigger outputs from the same file, although the ink spreading is an altogether different method from Real Printing and figures may differ accordingly. Tests with each combo will be useful. All I can say from own experience is that running 10D and D60 files on an Epson 9600 with the ImagePrint RIP at work , led to outputs of 40"x 50" of a fascinating quality( the RIP taking care of the interpolation), still giving major hopes to bigger outputs from the same files, since there was no detectable damage in the resulting print, perfect highlights, soft and detailed shadows,great skin tones,etc. I would not beleive it if I wouldn't see it myself. Happy New Year to all!! Jorge Parra. =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
