QTR-Quadtone RIP

QTRIP allows to select two sort of paper: Matte or Photo. Matte is rather obvious but what is Photo paper? It can't be Glossy Photo because glossy paper - as far as I know - is not supported by QTRIP e.g. on R800. Also my tests show that on glossy paper we may produce good prints but very easy to wipe even by a finger as gloss optimizer is not used in printing.

Together with the package two paper profiles are delivered: QTR Matte and QTR Photo. Also paper producer (e.g. Ilford) delivers it's own profiles. What profile we should use for printing? Own QTR or paper producer if available?

The photo paper option would cover glossy paper. QTR is not intended for 
use solely with the OEM inks, but also with third party inks (or even 
primarily for third part inks), so although it may be problematic to use 
the OEM inks and glossy paper on the R800, there may be other ink sets 
available for the R800 which are compatible. For some other printers, eg 
R2400 or 3880, the OEM inksets are usable with QTR and lustre or glossy 
papers (provided the appropriate black ink is in place in the R2400).
Paper producer profiles are usually intended for use with the standard 
Epson driver, not with QTR. Ideally you would produce your own custom 
curves for the papers and ink you are using, and use these together with 
the appropriate QTR ICC profile. Exactly how it all fits together varies 
significantly depending on the operating system you are using.

I use only EPSON native inks. This option is supported directly by QTRIP package.

However, I was trying hard to use glossy/semiglossy/pearl paper (Epson, Ilford) with "Photo Paper" QTRIP selection and always result was the same - good quality but very easy to wipe - very unstable - prints.
