Howdy

I have linearized what I believe is a well done profile, but when I print with the linearized 
profile...the print is  darker than anticipated.  I am able to make a good print by moving the 
Gamma setting in the print settings to a lower setting ( lighter).  Of course I would like to 
have a more optimum profile not requiring this last stage adjustment.

Any ideas how to readjust my profile to be closer to correct output?  Please understand the 
linearity is fine...very smooth with no bumps or posterization.   Output is just too dark....

I am thinking that perhaps I have set the basic ink limit too high.  Any other ideas of how I 
might correct my profile?

Thanks
