Re: Newbie here...

Thank you Howard, you are correct.  I'm glad it was a simple answer 
and I'm very appreciative.  

I have very little working knowledge in printing so I feel like I'm 
just jumping in with both feet.  I was reading the QTR manual about 
making linearized curves.  It would seem that by adjusting the values 
there, you could really create some very customizeable curve tones.  I 
was wondering if there was any kind of software tool that anyone has 
created here that might help visually approximate how playing with the 
values would change the look of the 21 step chart.  Does that make 
sense?  You would create your basic curve settings with no 
linearization values, then measure the ink densities in each step to 
baseline it, then play to see how putting in different values would 
change the curve?  Does that make sense?  If nothing is out there like 
that, I may try to work on something.

Thanks again,
Dan
