Re: Bronzing

I doubt that your residual bronzing is caused by or can be cured by changes to your QTR curve. Different papers need differing amounts of GO. Jon Cone once posted on the IJM forum a rough guide to GO amounts by commonly used papers.

My experience (not a lot as mostly I print K6 & K7 on matte) is that it can be hard to totally eliminate bronzing from K7. But then Epson inks are not totally immune from it either.

I have a K7 printer with over gloss. It also has the lastest HD inks from inkjet mall. I'm using Richard Boutwell's QTP software to make a profile for Harman Gloss Baryta. I am using the over gloss set at 3000. After making the profile (used a curve and linearization) and printing test images with the over gloss, I am seeing bronzing. I have not yet smoothed the profile or used QLin. Are there any remedies to eliminate the bronzing or reduce it?
Please advise.
Cheers,
John
