This is a follow-up from previous posts. I am trying to validate a profile using the commands below: >targen -v -d2 -G -f100 iPFTest >copy iPFTest.ti1 iPFRef.ti1 >printtarg -v -r -ii1 -a1.0 -T300 -M6 -pA4 iPFTest >cctiff -v -ia -e iPF6400-Canson-Baryta-310-Argyll-2584.icc iPFTest.tif iPFTestO.tif >move /Y iPFTestO.tif iPFTest.tif >Pause Print iPFTest.tif using no color management. >chartread iPFTest >fakeread -v -Ia -l iPF6400-Canson-Baryta-310-Argyll-2584.icc iPFRef >Pause The test results will be in iPFValidate.txt >colverify -v2 -N -k -s -w -x -L iPF6400-Canson-Baryta-310-Argyll-2584.icc iPFRef.ti3 iPFTest.ti3 > >iPFValidate.txt Here is a summary of the results: Total errors (CIEDE2000): peak = 2.775012, avg = 0.717430 Worst 10% errors (CIEDE2000): peak = 2.775012, avg = 2.054905 Best 90% errors (CIEDE2000): peak = 1.440833, avg = 0.584831 avg err X 0.005690, Y 0.006274, Z 0.004678 avg err L* 0.623982, a* 0.641691, b* 0.639550 The differences seem way too high, even allowing for a max dE00 of, say, 0.6 due to scan/print error. I've tried the same test with cctiff and fakeread set to Relative and the results are no better (but no worse). If I run colverify without the -N flag, the results are off the scale (dE00 of 40+). I've checked two of the spot colors using spotread with the following results: Spot 7 (had a dE00 of 0.5 from colverify): Chartread: 25.19, -53.19, 18.86 Spotread: 25.40, -52.85, 18.65 (dELab of 0.45) Spot 4 (had a dE00 of 2.31 from colverify) Chartread: 45.18, -63.73, 36.68 Spotread: 45.25, -63.30, 36.73 (dELab of 0.44) And, finally, I've scanned the same 100-patch target twice (with a calibration in between) to see how repeatable my scanning/instrument is, and here are the results: No of test patches in worst 10% are = 10 No of test patches in best 90% are = 90 Verify results: Total errors (CIEDE2000): peak = 0.232322, avg = 0.096521 Worst 10% errors (CIEDE2000): peak = 0.232322, avg = 0.214428 Best 90% errors (CIEDE2000): peak = 0.151862, avg = 0.085107 avg err X 0.000351, Y 0.000359, Z 0.000714 avg err L* 0.041514, a* 0.047190, b* 0.149554 Very repeatable, as you can see. As a final bit of information, here is how I made the profile: targen -v -d2 -G -e8 -B8 -f2688 %PROFILENAME% printtarg -v -ii1 -a0.83 -T300 -M6 -pA4 %PROFILENAME% chartread %PROFILENAME% colprof -v -A"Canon" -M"iPF6400" -D"%PROFILENAME%" -qh -cmd -dpe -SBetaRGB.icm -O"%PROFILENAME%.icc" %PROFILENAME% So am I doing something wrong in the validation commands or the profile-making commands above?
