AKA: What is this "Epson IJ Printer 07" color profile, or what does "ICM mode" mean. Warning: My instructions here are Windows only. There's probably a way to do this on Mac, but the color settings UI is a bit different on OSX so someone who actually owns any Apple products will probably have to chime in on how to adapt this there. Also, I'm not going to try to explain how to do color management in a forum post: there are much better articles for that. This is just about the weird alternate method for color management Epson provides. A non-photo model Epson printer, like the Workforce Pro WP-4530 I just got to replace an aging laser, can still produce some great photo output if you give it good paper (even with only 4 inks). The problem is that Epson doesn't provide any ICC/ICM profiles for the various papers on these units. There is still a way to do a limited form of color managed printing however, even without the individual paper profiles. It's weird, a little half-assed, and probably not quite as accurate, but if you find yourself in need of getting accurate color out of a business printer it's probably good enough. Here's how it works: While Epson doesn't provide individual profiles for this printer and all the compatible photo papers they do provide a single profile for the printer itself. In my case here this is the file "Epson IJ Printer 07.icc". What this file seems to provide is a general ball-park colorspace to translate your colors into and a special setting in the driver applies whatever translations it needs to get the colors right for the paper you've chosen. To do this you go into the driver color settings and select "ICM mode" where usually you would choose "no color adjustment" and the driver takes it from there. Another alternative in my case is an "AdobeRGB" option that should just assume it's input is in that colorspace, and I think I remember an "sRGB" in Epson drivers years ago as well. Advantages: It's convenient. Lets you have a default color profile set in Windows that doesn't need to be changed. This makes color management in only mildy color-aware programs possible, for example Irfanview with the LCMS plugin only lets you select the monitor profile and assumed working space. It's better than guess and check, and cheaper than a Colormunki. Disadvantages: Soft-proofing is probably a little meaningless. It'll probably still show how the profile manipulates out-of-gamut colors, but it can't say anything about how your printer works with this particular paper. Gamut is probably fairly narrow say sRGB or not much bigger, I haven't dug in and tested that yet, but I'd give it good odds. If you're going to have one profile be used for multiple papers, logically, you would choose a color gamut the printer can do a good job of for all those papers. The result should be a lowest-common denominator color space. Accuracy probably suffers a little, again I don't have a colormunki to test with. With two color transformations (one in the profile, the other in the driver's ICM mode) there's probably a little bit more munging math happening to the color values. Also the transformation hasn't been tuned individually for the exact settings being used. Doesn't help you with 3rd party papers. If your printer doesn't have at least 6 inks as far as Hahnemule, Red River, or Ilford are concerned you're on your own. Even then they may only deign to provide a profile if you shelled out at least half a grand for a 19" model. Can't really improve it with a custom profile for your printer: it would favor the paper you measured on. Doesn't work at all on plain paper. Not that there really is such a thing as an ICC profile for all plain paper, but the output here isn't even remotely accurate with plain paper. You're better off with a setting like "Epson Vivid" in that case. PS: I can almost guarantee this is covered somewhere in the archives here, but a recent Google search turned up a question with no good answers on what the "Epson IJ Printer 07" profile was and how it could be used to get color management working. This approach is so counter to the normal stream of advice I though it was worth reposting. That and I might as well return with a bang. PPS: It's been a long time since I played with the "ICM mode" settings and I haven't had the time to do a lot of testing on this new printer yet. There's a very small chance I could be completely, utterly, wrong.
