The ti3 file I posted is unchanged output from printread.


I have also played some more with the targen command, and I have now
managed to create the whole linearization target in one step. Earlier
I created one file for each color.
But there is a problem. I expected to get 40 patches from each c,m,y,k
and cmy, but I only get 40 from cyan.
My command is:
targen  -d 2  -D 4 -f 0 -s 0 -s 40 -g 40 -e 0 -m 0  lin-target
printtarg -v -e -ii1 -r -pA4 lin-target

The results is:
40   c
39   m
39   y
39   k
39   cmy

It drops the 0 patch on all stripes besides cyan.
==> c <==

Is this a bug, or am I misuse targen, or have wrong expectations?
