Digital BW, The Print

This suggests it is an "overspray" ie it is applied evenly to the entire
image (or even page) rather than a filler dependent on the deposit of other
ink:

Remember also that the R800 can gloss the entire paper - outside the image
area's borders. Note the use of "fit to page" in the instructions above.

I would use either the Cyan or Magenta slot so that (assuming you are using
UC colour inks rather than quads) you still have access to LC, LM and Y for
cooling/toning.  In the 21/2200 UC curves an equal amount of LC and LM are
used to cool the LK.
