I've seen lots of out-of-date, confused, and simply wrong answers to this question and have had a hard time sorting through what might be right. Here's the situation. In ColorMunki, when you are calibrating a printer, you get a print dialog box. In older versions of the Mac OS, within the print dialog there was a way to access the Page Setup window; in Mavericks, there isn't. To select any of the Epson Fine Art Papers for use on the Epson 3880, you have to access Page Setup so you can set it to use the rear feed. Since you can't get to the Page Setup from within ColorMunki, you apparently can't create a printer profile for those papers (or any papers that use one of those paper types for setup, like Hahnemühle Matte papers). I'm sure there are workarounds, but I can't find one that works. I'm assuming one of the ways would be to create a PDF and print it with photoshop and then measure it with the ColorMunki, but how to be sure about whether or not that PDF is being color managed correctly or not at all and which would be the correct approach. Any help is appreciated.
