Digital BW, The Print

I have been producing single color line film negatives on an HP 8750 Photo-smart and an EPSON 2200 for a couple of years. I have had WIDELY ERRATIC results depending on which color combination and/or density I choose to print on which brand of transparency (3M, Kodak, HP, Epson, OfficeDepot, OfficeMax, Xerox, Parrot, etc) and TYPE (glossy, satin, matte) of clear substrate I used. The EPSON has failed more often and in nearly every way - but the HP was capable of producing line film negs with qualifying results - though very short of linotronic quality. My production does not always need full density negs (limited sepia transparency is okay with my wide-latitude emulsions). I do know of silk screeners and photographers successfully using an EPSON 7700, 9700 AND 10000 for vector art and CMYK film pos's. They report full density blacks. My biggest problem has been in producing line film neg separations because the transport doesn't critically match from one print to the next - gaining or losing as much as a 32nd of an inch over 11 inches. I will be interested in the film neg solution for our recently acquired HP Z3200 - which I still need to test with my film neg technique - once I find some substrate. I produce film negs from VECTOR art (Illustrator) as well as CMYK/RGB raster (Photoshop).
