i1 Profiler Scanner module, clipping white
Creating scanner input profiles with the scanner module in i1 Profiler seems to create profiles that clip the white point. I created a Version 4 profile that clips more than a Version 2. Scanned a Colorchecker 24 and then processed in i1 Profiler. The resulting profile used in Epson Scan application clips the white patch perilously close to pure white with a Version 4 icc profile. Of course I am using the Colorsync configuration in the scanning application. The Version 2 clips less but still pushes the white patch high enough to cause potential clipping in originals that are brighter than the white patch of the Colorchecker 24. Anyone experience this?

Yes. But I'd blame the scanner for this, not the profiling software :-) I tried to tame an Epson 10000XL A3 scanner when we were having problems with our Fuji Lanovia. The Epson software made it really difficult to lock the scanner settings down — meaning that each scanning session would yield different results for the same chart even when you’d made every effort to keep the settings locked and consistent. I use custom made charts on the print material we were scanning — mostly Kodak Endura, Fuji Gloss and Fuji Super Gloss — but we’d still get variable results and clipping too. The profiles were made in Profilemaker as, unlike i1Profiler, you have the flexibility to create your own custom chart designs. I reckoned that the variation was due to slackness in the Epson’s internal pre-scan white point calibration? So, providing the scan you used to create the profile didn’t clip the white, manually editing the production scans prior to applying the profile to ensure their white doesn’t clip should give you reasonable results. -- Martin Orpen Idea Digital Imaging Ltd
