In some test prints on Ilford Gold Fiber Silk, I’m getting some gloss differential where the quarter tones transition into the highlights. RGB values around 215. It reminds me of printing on my 9800 with P2 inks where the IGFS and other similar papers (Canson Baryta, HFA Photo Silk Baryta) needed 2 or 3 passes with GO to eliminate bronzing. It’s not as severe as a P2 print with the IGFS or its clones, but it’s there.
How does one increase the CGO applied? It was straightforward to modify the GO curves, not sure with the PiezoPro curves.
Hi Walker.
I hope everything is good. Strange times.
I have the same problem with bronzing. I’m printing on a 9900, on MediaJet Museum Natural Silk.
You can clearly see a matt surface in the darker tones.
I have replaced the LLK Section according to your instructions above and when I open the curve in QTR-CurveView I can see that the LLK curve has changed.
However, when I print I can see absolutely no change in the matt areas. ??
The paper is glossy and I’m using HDPK ink. I have tried several different paper curves but they are all giving the same result.
I’m starting to think the problem is something else.
I set the printer up last winter and I have been busy doing other stuff since then.
When I look back at the test prints I made back then, the gloss is perfect (on the same paper) , very even in all tones.
Can the gloss solution get old ? Have tried different paper batches and I can also see the problem on Hahnemuhle Fine Art Baryta.
A nossle check looks ok.
I hope you can see what I mean on the photos.
