Hi,
Ah great. How can I read the deltaE from the ti3 file?
you need to compare to a reference file, and use
colverify to compute delta E values.
One more important question. My argyll cmyk profiles always have a strong
noise/grid compared to
the rgb profiles. I've tried -k (z, h, kx) but it hasn't gotten any better.
What is my misttake?
This is my profiling workflow:
Typically this is caused by a strong non-linearity in the device response.
Increasing the table resolution (-q) can help a little, but the biggest
influence is the black generation. Some experiments with different
black levels may help in making the device response more controllable.
