Hi,
I'm trying to create an icc profile for my Canon printer using a DTP20 device.
In order to do that I followed to instruction in the "Typical usage Scenarios
and Examples" section on the Argyll website.
The targets were obtained by issuing the following commands
* targen -v -G -d4 -l400 -f2160 -B16 -e16 -g128 Canon
* printtarg -v -i20 -pA4 Canon
and printing the created .ps file with all color correction options turned off.
The prints were left to dry for a couple of hours and were read in using
* chartread -v -c1 -h Canon
This took quite some effort because very often communication problems occured
with the DTP20 (seems to be some initialisation issue: either it works
perfectly or it will only give communication errors after connecting the
device) but finally I did succeed.
If I then try to create an icc profile from the results using
* colprof -v -qh -i D50 -o 1931_2 -S AdobeRGB1998.icc -cmt -dpp Canon
I get the following error:
colprof: Error - gamut: vector_isect failed!
Changing several options does not make any difference.
Taking a closer look at the output of colprof, at several locations "-nan"
occur. This starts (I think) when the black point is determined because in the
output the first occurence is in the line
Black point XYZ = -nan -nan -nan, Lab = -nan -nan -nan
I have no clue what I am doing wrong. Should I use different options?
Any help is greatly appreciated!
Sander
