I just picked up a Colormunki Photo to profile my printer. I'm using an MBP, and the first step is to profile the monitor since it has to match the printer. I've tried the process about a dozen times with various settings and versions of the software, different angles for the sensor, etc. And I very consistently get and intense brown color cast. Even their sample image looks good with the default apple profile and like crap with the Colormunki profile. Any suggestions on what I might be doing wrong, or is it possible I have a defective unit? Thanks.
