I recently set up a 3880 with the Piezography DN system and the neutral inks with the HD black inks. I’ve made successful digital negs and the matte prints on Canson Matte rag are all normal. Yesterday I ran a couple of prints through on Canson Platine and the print color and linearization with the supplied curves give very smooth and subtlety dimensional results. I was impressed. The problem I’m having though is extreme bronzing and extreme gloss differential between the ink surface and the paper base. The gloss enhancer tank is full and it seems to me that is being applied but if it is it’s certainly not enough. This is a one pass system right? What am I doing wrong? If I spray these prints with three heavy coats of Hahnemühle Protective Spray they are fine, but I’d rather have the option of not doing that or have to run the print back through the printer for the glop coat.
