Here's my setup: 27" iMac, OSX 10.8.3, running LR4.4...connected to an iPF8100. The 8100 is running the latest f/w version and I also have the most current driver installed.
I split-tone my b&w pictures - subtle, but there's color added.
In the LR Print Job section, under Color Management, I've got my Canson Baryta profile loaded. When I bring up the print settings dialog and select the Color Matching drop-down menu, ColorSync is selected but both ColorSync and Vendor Matching are greyed out. If I go to the Main drop-down, Color Mode is set to No Color Correction, and this is greyed out. Should be good to go, no?
When I print, I'm not getting my split-tone color. Prints are coming out neutral. Any thoughts?
