deterioration of a misprints

I’m working with water-based mediums to fix the ink on uncoated smooth film and mylar. In this Misprint, I used a gum Arabic medium I prepared myself, and it seems to work for the first few weeks, but after changes in humidity, the piece disintegrated. In the dark tones, the ink cracked and separated from the substrate. I took this photo before the pieces broke apart and attempted to re-fix using an acrylic medium that seems to work well.
