Re: Digital Negatives and new Epson printers
Very hard to say, but if the vertical marks are not there to begin with on the substrate it must be caused by the material moving over some impediment in the printer. Perhaps one of the wheels or rollers has locked up? Sandy At 12:27 PM -0500 2/21/07, SusanV wrote: Sandy, A little off topic of this thread, but your mention of pizza wheel marks reminded me.... My 1280 is causing vertical marks on the Pictorico OHP I'm using. They are not inked marks, but seem to be long scratches on the back of the film. Any idea what those are? thanks, Susan gravure blog at http://susanvossgravures.blogspot.com www.dalyvoss.com On 2/21/07, Sandy King <sanking@clemson.edu> wrote:Hi Markek, I used the very inexpensive Ultrafine OHP from PhotoWarehouse with the Epson 1400 and there was no problem at all. In fact, the Claria inks of the 1400 appear to dry a lot faster on this substrate than when printing with my Epson 2200. I have not seen any sign at all of smearing and puddling with any of the colors, nor of any pizza wheel marks. With the 3800 I used both Picorico and the Ultrafine OHP. The inks did noit smear or puddle, but there were some pizza wheel marks on the Ultrafine with some of the colors, but not on Pictorico. I think this is because some of the colors of the 3800 dry slower than others. So far I have not made any color prints with the 1400, but reviews are very good. B&W printing will be another issue, however, as so far I have been unable to print a neutral tone step wedge, though this is not relevant to my anticipated use of the printer for making digital negatives. However, I plan to use the 1400 primarily for printing digital negatives and early tests strongly suggest that it will print smoother than the 2200.

Did you see any evidence of ink smearing and puddling when printing high density with all colours? I would be more interested in hearing if it can handle both cheap and expensive transparencies. I use cheap transparencies for negatives for gum prinitng and pictorico for palladium and everything else. I currently use 2200 so it is a benchmark for me. This seems like potantially a perfect printer replacement for me as density of 1.8 is exacty what I need for Pd and I have been using curves to adjust density lower for gum. How is the quality of the color print on that 1400 printer. Are the dye inks producing really deep rich colour?
