Re: gas

I'm not too sure re the last sentence as it implies there is an oxide
in the inks of Epson?
But, I think . . think mind you . . that Epson inks in the
Ultrachrome variety VS the dye . . are
encapsulated. So, on a luster paper, which many photographers prefer
(or semimatte) due
to the greater DMax hence deeper black hence greater apparent
contrast, that on this luster
paper the inks 'sit'. Whereas on matte papers, the inks 'sink' into
the paper. The inks lying upon
the surface, minus the encapsulation, tend to off-gas. If I remember
correctly, Epson has
recommended that one allow such paper/ink combos to off-gas for a
while (maybe a couple of
weeks or more) prior to placing behind gas. So, after my long blah,
blah and more blah, here,
it is indeed not wise to put a 'fresh' print behind glass.
