Getting perfect neutral prints from Epson 7600/9600 etc
2002-08-17 by thedigitaldog
Yesterday I spent the day working with the president of ColorByte (they make Image Print), Photographer Greg Gorman and the new version of the software that drives the 9600/7600 (and within two weeks) the 2200. Gorman is trying get neutral B&W using all inks (like many of you). We've built custom profiles with the Epson driver but after yesterday, I'm understanding that this isn't necessary and that the huge issues with neutrality are primarily the Epson driver. The prints we made were DEAD NUTS NEUTRAL from the entire tonal range. NO metamerism what so ever (ColorByte's special grayscale mode doesn't use any yellow ink which is the cause for metamerism). We viewed prints under a GretagMacbeth "Judge II" light box which simulates Daylight (D50), Tungsten, Cool White Florescent lights etc. The prints were perfectly neutral. The dither is superior to Epsons. The dMax was significantly better when sending identical data to the printer using Epson driver (with custom profile) verses the canned paper profiles from ColorByte. We were, needless to say, blown away. We need some profiles from ColorByte to see what can be done in color. I've seen output from Image Print to a 7600 at a recent show and they looked awesome. I'd like to wait until we've tested color with our own set of tests before commenting further. But if Image Print can print B&W images like this to our Epson's, I can't see why we will not get awesome color. The smoothness of tones is like butter. Image Print uses 8000 levels of screening (Epson we were told uses a few hundred). All this and the print times are the same as using the Epson driver. The issues with neutral prints is no longer an issue! I'm not kidding when I say that looking at output from the old printing methods verses with Image Print, it was like working with a totally new printer. This isn't the 9600 output Greg and I have been testing for the last 5 or 6 months (we did beta on the printer). The quality results are 100% superior to anything we've ever seen.
