I would say that UT-14 prints a neutral tone. I have experimented with changing the tone using curves and created neutral and warm tone curves for printing on glossy paper. The curves limit the amount of ebony in so that there are no problems with smearing on glossy paper. I don't normally use these on matte papers as matte papers have no problems with the ebony ink, but I don't see any reason they would not work if you wanted a warmer tone.
I posted a set of instructions for using these at http://1drv.ms/1qJPklL and the article has links to the actual .acv files that you will need to download and put into your Photoshop director.
