Re: digital negatives and Epson printers
I don't think you "have" to use a RIP and an all-black inkset -- but I think if it so happens that you are also making Black & White inkjet prints using this method it would make more sense than constantly changing ink carts and purging the printer, or dedicating a printer. The RIP method(s) with seven-different-tones-of-black will typically use one or more of the lightest inks in the lightest shadow areas, then combines four or more inks in the mid-tones and then again uses two or more of the blackest inks to create highest densities. Whether or not this yields better "detail" in the final print is still a subject for debate, or may not matter depending on some of other variables (read: paper or the process). In the end "a dot is a dot", if the density is made of a bunch of varying tones of black dots as opposed to a bunch of varying tones of coloured dots may be six-of-one and half-a-dozen (or K7) of the other. ~m ----- Original Message ----- From: "Erich Camerling" <e.camerling@tiscali.nl> To: <sanking@clemson.edu>; "alt- photo-process" <alt-photo-process-l@usask.ca> Sent: Monday, July 16, 2007 11:33 PM Subject: digital negatives and Epson printers > > Hi Sandy, > > Thank you very much for your answer about digital negatives (3 jul 2007) > You did advise : buy the Epson R 1800 (or 3800 or HP 9180) That is clear > but why "replace the inks with the Piezography K7 inkset" and how I have > "to dedicate to digital negatives".Is that an 1800 printer setting ? > Is there practical experience with clogging or just no-clogging over a > longer period of not using the printer (vacation !)with the K7 ink ? > That the beta-tester from Piezography reports : "WOW,no clogging" does > only mean for me that there is no clogging in the beginning . > Is it necessary to use QuadTone RIP ? > Hope you know the answers on my questions. > > Erich >
