The problem occures on epson printer with proof manager and profile
assigned. Test image was iso coated cmyk gradients 0-100% each
Calibration was made remotely  so i only based on telephone conversation,
and differences to good reference print.
Soon  i'll get the some test strips printed on new profile to read, then
I'll get solid data,

profile was maked this way:

chartread -v -H -T0.4
colprof -v -qu -D"t1" -qm -S AdobeRGB1998.icc -cmt -dpp t1
profcheck -v2 -k -i D50 -o 1931_2 -w t1.ti3 t1.icm > t1.log

all files are  here http://www.artifot.pl/!test/

Did i made mistake somewhere?
I hope that data help to make some judgment.

Btw i saw profilemaker 5  charts a4page  that had 40x40  paches on a4 card
is it possible to get higher density sampes on page and safe to read with
standard i1pro hand ruler?
