But the human eye needs 100 or so levels to see perfectly smooth tonal transitions. The Epson 2200, for instance, claims a maximum resolution of 2880x1440, which means it can fit about 47 levels into that area using black-only. If you want to print at 300 DPI then your printer has to have high enough resolution to fit a complete tonal range into. ![]() The other problem with black-only printing is that ALL dithering schemes represent a tradeoff between color (or grayscale) resolution and spatial resolution. True but then it will have a fine pattern of black dots, which many people will find annoying and distracting. But by golly, that print will NOT have a color cast! If you do that with Epson, a "warning" box pops up telling you the world will end. I'm not familiar with Canon's printer, but if it has a separate black cartridge and the driver allows it, select Black-only ink. ![]() So despite what you say at the beginning, apparently it IS possible to get good black and white from a 7-ink system if you are willing to pay for it.īTW, the Epson "light black" ink is brown, not gray. Other people use the Imageprint RIP to fix the 2200's black and white problems but it costs over $500. Epson even sells a solution for it in the form of a $200 RIP, which some people have tried and reported good results with. The 2200's black and white metamerism is a hot topic of conversation on the Yahoo Digital Black and White printing group. Those with window cubes (i.e., daylight) commented on how it looked greenish. If you don't notice this get your eyes checked - I brought the Epson sample to work and everyone with a cube on the inside of the building (i.e., with fluorescent light) commented on how it looked pinkish. ![]() Change the light source and it goes Technicolor on you. The sample print you refer to may have no cast, but it has wicked bad metamerism! I.e., it has no cast in a specific light. The Epson 2200 has photo black, matte black (photo and matte are mutually exclusive, though), and light black.īetter look again. The B&W sample on matte paper included with the printer has no cast to it. I do have hope for my new Epson 2200, though. In bright light you use mainly the cones in your retina but you can still see a neutral grayscale. There is no way it will ever do good B&W, because it uses color inks to produce the shades.
