Using QTR on a UC 7600 and Epson Premium Semimatte paper

Using QTR on a UC 7600 and Epson Premium Semimatte paper

2006-06-08 by Laboratório de Documentação Científi

Hi all,
I'm trying to use QTR on our 7600 with UC inks to print on Epson 
Premium Semimatte paper, and I'm having some trouble setting the curves 
parameters right. Does anyone have a sugestion of a downloadable curve 
that would be suitable for this setup, or at least that would work as a 
starting point? Thanks for any help.

Hi,
I've posted this a while ago but got no reply; does anyone have a 
suggestion about a "starting point" QTR curve for using Ultrachrome 
(K2) inks on Epson Premium Semimatte with a 7600? I'm having some 
trouble adjusting the ink parameters for a 'cool' curve: the 21-step 
image prints with very non-even densities, mainly in the mid-gray tones 
(60-80%), and the 100% patch is noticeably lighter than the 95%. I 
suspect the trouble may lie on the LC/LM ink limit settings (I'm using 
a default LIMIT_LC=27, LIMIT_LM=27, LIMIT_LK=56, and the overall ink 
limit is set at 40%). A warm curve prints and is linearized OK.
Thanks for any help,

Paulo Baptista
