Yes, there are remedies. The remedy is to use the K7 curves I built for the HD inks downloadable here: https://piezography.com/downloads/piezography-community-edition <https://piezography.com/downloads/piezography-community-edition>

I made these curves using a totally different (and weird) curve builder that I built specifically for fixing bronzing along the linear slope from dark through light then I used two curves which were built for opposite curve bronzing. It gets more complicated than that but long story short, Richard’s curve creator does not have the ability to calculate bronzing corrections. You’ll notice (for example) that the Cyan (shade 2) on the HDPK master curve actually follows the PK curve and is LESS than it. The Shade 2 acts as a bronzing minimizer.

Use the HDPK master curve for your ink-set and gloss optimize with 30000 GO curve to start. If you have Piezography Professional Edition you can use the curve blender tool there to also correct for gloss bronzing by “blending” the normal PK master and HD-PK master quad together as well. This allows for bronze elimination tweaks per paper. This is totally unique to Piezography Professional Toolset and is not anywhere else.

Best,
Walker

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?
