In my experience magnification on screen is largely irrelevant when determining optimum sharpening for print. What I do to test a particular printer/page size is produce a test image with a 1:1 pixel crop pasted repeatedly across the page, each with an increasing degree of sharpening. I then have it printed and use the resultant page to visually determine the optimum sharpening factors. My results are near optimum for a particular print size and are also consistent print to print. I've put one such test page up as an example, it is representative of an over sampled *ist D image (4024x2733px): http://home.swiftdsl.com.au/~distudio/temp/usmtest.jpg (~3MB) Over the years I've developed my own digital image pre-print procedures and solutions, sometimes they correlate with the popular "experts" methods sometimes they don't but usually they are effective :-) Cheers, Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998
