Re: Eboni Variable Tone updates

2016-04-03 by andrey@...

Paul R or anyone else who knows,

How does one determine the neutralizing toner settings in the .qidf file? The main lever I've been pulling is the Y limit, as the TONER_VAL_1 value doesn't seem to have much effect. I'm trying to neutralize the 5-shade Eboni 1.1 on Epson Ultra Premium Presentation Paper Matte (because it's cheap, and a good way to get the workflow down before moving to more expensive paper), and the Lab b swings are kind of big and not easily controlled when I change the Y limit. Also, I set some value, and then I print a stepwedge to see how it does. Is there a more deterministic way to do this?

From looking through the archives, it seems like changing the limit is the main way people deal with the toner.

Here's a link to 3 different measurements, all text output from the QTR-Linearize-Data app, as well as the. qidf file. All of these files are not linearized. The toner mix is the 75% dilution of the Canon blue and cyan inks at Paul's ratios.

Thanks in advance for any help!
