Mike, the new Profiler software from Xrite allows one to generate profiles in .icc version 2 or .icc version 4.  Xrite suggests using the newer version 4 generation.  I have Q Studio (latest update) and it does not work with the .icc version 4 profiles I generate.  .icc version 2 generated profiles do work, however.  Any chance of updating Q to work with both .icc versions?  I have tried both with Photoshop CS5-64bit and both version 2 and 4 print properly.  When using a .icc version 4 profile with Q, the print is made with a very deep cyan cast.  This cyan cast also shows in the print preview dialog for the Epson7600.  The preview dialog normaly has a bit of a magenta/red cast for proper print generation with a 7600 when the program manages color.

Thanks, Dennis
