Currently I am using Cone’s Vivid k3 on my Epson 3880, and I have been testing the ink with the Castco glossy paper. The dark shadows and the blacks have almost no detail. I will appreciate suggestions how to correct this problem.
I suggest using the Epson premium glossy profile and media setting, and also trying Perceptual intent. If that doesn’t product acceptable results, have a custom curve made for your specific printer/ink/paper combination for the best possible results.

I hope this helps, best regards~ Dana
