Advice for unflat paper... Maryly Snow 12 Jul 2018 15:18 PDT

I have 2 pieces of paper with glued collage elements on them and ink etched plates.
There were 2 mild dinks, one on each sheet.

So I lightly dampened the areas in question,
put them in between thick blotters, weighted them down, let them sit for several days.

Now the mild dinks are much larger and more noticeable!

Is the only solution to put them in a damp pack, then run them through the press?
