Improving Dither

2005-08-26 by John Moody

Can profiles affect dither patterns in any large way? I\u2019m talking about tweaks to one profile, not profiles for different papers, inks, etc.

Soon, I will be spending significant time creating profiles for a modified UT7 set, and if there is a way to improve the dither pattern I would like to incorporate that.

I\u2019m currently printing with 2200 UC inks on EEM.

Specifically, I see sparse dark dots in the ¾ tones that I do not see when printing through the Epson driver. By sparse, I mean there are maybe 10 dots between the dark dots. Printing modes are,1440 super on QTR better speed, 1440 no-high-speed on Epson driver. QTR is far superior in every way, other than dither patterns. I would like to find a way to do better.

Best regards,

John Moody
