Hi,
I use collink.exe utility to linearize my printer
using device link profiles, but can`t get what i want=(
I make profile ising -o option.
You mean the -O option ?
i.e.:
collink -O test.cal test.icm
There is my .cal file listing:

When I apply resulting profile to image in Photoshop,
I expect to have these tone value increase values:
0 0
5 1
10 2
20 4
30 8
40 12
50 16
60 12
70 8
80 4
90 2
95 1
100 0
That's not what I would expect from your data, and it's not
what I get from the resulting link:

I don't know why it isn't working for you.
