Hello Jani!

Thanks for your reply.

When coating is applied, AxisControl will try to get to ISO targets as close as possible by opening/closing ink keys. The doubt are that there is too much of ink under coating and printing so much ink makes process very unstable. Also dot gain becomes very high.

What does ISO says about coating? Does coated sheet should hit same targets as uncoated? Even when coating makes inks less saturated?
What is your experience what do customers require?

regards,
Juris

Hello Juris.

I would suggest not print varnish on colorbar.
But if somebody has investicated different target values for printing CMYK+varnish, it could be interesting to hear.
We have made some test.. If the desaturation could be compensated by increasing density, color densities should be increased by 8-11%. It might cause invalid tvi values, and that should be compensated in prepress.
After all, the final result is not the same if you increase density on varnish job vs leaving the varnish away.
Matt varnish desaturates, and that is what it is for.
