FWIW, I have been unable to PRINT from C1 and get anything remotely color matched. If I export a TIFF and print from Lightroom, Photoshop, or Aperture, then all is well. If I print a test jpeg from C1, it looks good as well.. What has not worked at all is printing directly from a RAW file within C1. (This is on a Mac Pro with OS 10.7.4, and C1 6.x)
I'm not the only one, as I've seen this mentioned on the C1 fora, but haven't checked recently to see if it has been fixed. Ill try again when C1 7 comes out.
