Hi I get a scanner profile (colprof) with too high DE >40. The procedure: - I create my own target with ./targen -v -d 3 -s 21 -g 21 -f 513 -c Cruse_LRFB.icc Scanner (ti1 file attached) by using a previous icc profile of the same scanner. - Create test chart with printtarg -s (cht attached) and print it with Epson printer. - I read the print with Barbieri LFP spectrophotometer and use XYZ values as ref. file (attached). - Read scanned image (attached downscaled to 30% for e-mail) with scanin -v -dipn ScanRef1.tif Scanner.cht ScannerRef-1.xyz.txt and get ti3 file (attached); diag.tif file shows patches are perfectly recognized - Create icc profile with colprof I double checked all data and it looks good to me, nevertheless the profile is unusable. Any idea what I am doing wrong? Regards Klaus Kompatscher
