Epson R2400 and Lightroom 4.2
I downloaded the latest Epson software and profiles. So, I was surprised not to see a profile for this paper. I also noticed that in the paper selection pulldown, this is not listed. There are only about 3 papers listed - gloss, lustre and semi-gloss.
Ultra Premium Presentation Paper Matte should be available as a selection when allowing the printer to manage color, even if you have photo black ink selected, unless this has changed in recent drivers. It is on p69 of the manual. Perhaps this is no longer available when photo black is selected?
When turning off color management in the driver and using LR to manage color, if the profile doesn’t appear in the drop down list of profiles in the Print module, try ‘Other…’, at the bottom of the profile list.
If the profile isn’t available in Lightroom, then check the list of installed profiles on your system. In Windows > Control Panel > Color Management > All Profiles. On a Mac, the profiles should be stored in /Library/ColorSync/Profiles. If the profiles is installed on your system but not appearing in LR, try closing and restarting LR. If that doesn’t work, try rebooting.
