Ok, I've been following this thread and do agree with almost everything said about Colorsync. I am a Mac person thru and thru but I just couldn't take the problems any longer between Apple, Epson, Adobe.
And then to top it off the i1 Match software has a conflict with SL. I did something I never thought I would do in a 100 years. I hooked up a pc running as a print server to my wide format printers and installed Qimage. I do everything on my Mac and then move the files to the pc and print thru Qimage. No more grey bars, blue haze, pc doesn't care if it is a V4 or V2 profile. I don't worry if the print will come out ok or not, jobs are recalled with all settings. Like I said, I can't believe I resorted to going that route but my workflow is so much better and the prints are wonderful. Yes, I love my Macs and will always be a Mac person but for now and the foreseeable future my pc print server and Qimage have taken all the stress out of printing.
