Hi - I just installed the deluxe P2DN system on my 3880 last week. I tested with the K3 ink set before installing the flush carts, all nozzle checks were clean. After the three power clean cycles with Piezo Flush (perfect nozzle checks), I then switched over to the P2DN K6 ink set. I read, verified, and triple checked that each ink was filled and installed in the proper cart / ink position. After another three power clean cycles, I ran a couple test prints, and everything seemed to look OK. A little dark, but I expected this due to not having any of the profiled papers on hand. My main reason for switching to the P2DN system was for the DN portion of the system. As I researched each system before purcahse, I must have read the [B]New Piezpography manua[/B]l five times through… So I don’t think I missed anything in terms of workflow. I selected an image that printed well on paper, and went through the negative conversion process. Greyscale, Gama 2.2, flip horizontal, and invert. I then saved as a copy, and opened in QTR Print Tool. Verified Gama 2.2, adjusted position on the page, and clicked print. QTR K7 came up, and I went in and made the suggested selections… Selected the [B]P2M-PZDN-X800-Meth3-1_6v3.quad[/B] for curve 1(other two were left un-selected), selected 2880, Uni-directional, matte black ink, and made no further adjustments. Side note… I tried making negs on both Pictorico Ultra premium, and standard premium OHP films. When the negative printed, everything looked great. I let it dry over night, and finally went in and ran an exposure test with my UV light source (12 BLB 24" tubes). After the test, I decided 7.5 minutes would work. Ran the print through the UV and developer, and all highlights were blocked. I realized I probably jumped a little far ahead, so I went back and printed a 21 step wedge with all available density curves 1.4-1.8. On average I wasn’t able to get any tone in the highlights below 35 on the step wedge. I repeated on three different papers. Scratching my head, and feeling like the system was way too easy to use, I decided to contact print the 2/14x2/14 in camera neg. Deep blacks, and detailed mid to highlight tones, so I feel my PT/PD process is ok. So, my question is, am I missing something in the process? I feel like the printed negative looks far too much like the original print file. I know the PZDN system is completely different than any other K3 system, but the negs look nothing like the flat grey version I made before switching over. I do apologize for such a long first post here, just wanting to provide details.
