I did the same with inkjet prints. Given the right kind of paper I
sort of like tritone images printed on an inkjet printer ("digi-alt
prints"). The only thing I found disturbing were the dull, sunk in
colours rendering especially the shadows somewhat flat. So I cut a
mask in the size of the image and applied a glossy fixative from a
spray can ("Marabu"). The prints came out quite nicely and because of
the mask the non-image area retained its original paper surface.
To get an even and lustrous coating it is better to apply to quite
heavy coatings. But because of the uncertain nature of the solvent I
feel hesitant to subject my laborious gum prints to this procedure.

As I said, I havent yet tried glossy acrylic dispersion as a varnish.
I would start trying with a 1:4 dilution using a soft brush on a well
settled print. I have used the matte stuff at full strength for
water-proofing a wooden board. Works well for the purpose but it
shows the brushing marks. (But then I used a rough bristle brush.)

No, the sizing absolutely withstands the wet-processes, even at
higher temperatures. For sizing I use 1:30 to 1:20. The advantages:
(1) the sizing is very simple to apply, (2) a singe coating usually
suffices, (3) it is virtually unnoticable (you need to pencil a mark
to tell which side is sized!), (4) it involves no health hazard, (5)
it effectively seals the paper (thus preventing staining) while
leaving enough textures for the gum/pigment to cling to (thus being
less prone to flocking off). Previously I used gelatine/alum for
sizing but now I much prefer the method with acrylic.
