I am very interested in this subject and I have on and off over the years done some testing but nothing recently.
One absolute requirement: Single pass printing and single sheet (no stacking). There is no way that high resolution can be achieved in a regular printer if the paper is inserted twice.
As you all know there are two goals: UV opacity & resolution.
I started testing a few years ago with three printers, four different types of paper and each ink color. A LOT of test combinations!! I measured opacity vs. wavelength with a spectrometer and I used my resolution chart. Unfortunately I ran out of time before having time to write up the testing and data.
Here is the test chart and procedure info:
