Re: New linearization test image uploaded

2006-12-11 by Kevin Bradford

Greetings all,

I too did a test using Graham's test file with similar results and would
be interested in any suggestions on which direction to pursue to improve
my profile.

My setup is:  Epson R2400 / Windows / QTR / 1440 resolution UCpk, MIS
LK, LLK, EZW-Yellow ink set,  Hahnemühle Fine Art Pearl.


I printed Graham's test image after my initial linearization of the
profile for this ink/paper combination and was surprised.   The QTR
linearization seemed good and the step tablet printed smoothly as well.
But as Joost noted, I saw some slight banding on the test file spherical
images.

I was not sure how to correct for this problem so I tried changing
densities and limits in different combinations.  Since my QTR
linearization curve was virtually straight I did not make changes there.
Nothing seemed to help.  I did not try changing the dither algorithm.  
Any  ideas?

Thanks in advance,

Kevin
