Re: Lumpy Curve when profiling glossy paper

2008-08-03 by Michael T. Murphy

Here are my Epson K2 Photo Black values on the first 21 step chart.  
You can see a couple of inversions in the L values. This is at 100%.

This is where the "polishing your print with a cloth" technique comes 
in handy. I am too lazy though, I just settled for lower K values. ;>)

I think I wound up setting the ink limit at "55", and got a 21 step 
value of "9.1" at 100.  

I was really trying to open the curves up in the highlights for 
portraits though.
