Digital BW, The Print

Been using Lyson Print Guard on and off for some time.  It seems to 
work well on just about any surface, and with a few coats, it acts a 
bit like a gloss optimiser on ultrachrome prints.  adds to the cost 
per print, though.

One thing I have never been clear about is Printguard and 
outgassing.  If you spray a print made on glossy or semiglsoss paper 
immediately its printed, is that an end to the outgassing phenomenon, 
or would you be storing up problems for the future?
