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.
