QTR-Quadtone RIP

Thanks for your response, Paul. That info is very handy. I managed to also find a previous thread that you wrote in, describing how to determine max black and "Black Boost" in a more empirical way.

However, I'm still a little confused. The QTR manual offers a way to compensate for dot gain, yet below, you seem to be suggesting that the dot gain curve in QTR is not a very significant quality factor. 

I am trying to understand why this is the case? Is it because the black / gray curve linearization process is a method in itself for compensating for dot gain?

Or, is it more a case that dot gain on an inkjet (using inkjet paper) is so minimal that it is an insignificant issue?

Many thanks again, and apologies for my annoying questions.
