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?
