Re: Epson 3800 vs 4800 - any advice?
Sandy, My preference for PDN, if the density is not sufficient, is to use Ink Configuration to lay down more ink. Oddly enough on the large format printers, this setting is under Paper Configuration and is called I believe Ink Density. A good reason for doing this is that once you add black to the PDN colors, you may get a color that Photoshop cannot parse into 256 tones. So, some colors are unable to render a full 256 tones—one color I tested dropped 50+ of the 256 tones. This occurs as a sort of periodic posterization in the image. All the colors used by PDN avoid this.

That is, if you print an RGB negative using all of the inks, that is what you get, or close to it. If you want to add some black to one of th PDN colors, just make another 360 ppi layer of the step tablet, fill it with black, and then blend with the colored layer to give you however much density you need. With the Epson 2200 virtually any maximum density is possible, from the 2.00 or so with Green by itself, to around 3.8 or so with black. You won't have as much range with the 3800, however. ************************************** AOL now offers free email to everyone. Find out more about what's free from AOL at http://www.aol.com.
