Giclee print restoration

I’ve been asked to restore a couple of acrylic paintings by someone local. She brought the paintings over today and after looking at them I realized that they are prints on canvas. She purchased them in the late 90’s so I’m assuming the process was giclee.

There’s a bulge in the canvas and normally with a loose canvas I would spray the back with water to fix it. I’m not sure this can be done with this print.

I’m wondering if anyone has experience with fixing a printed canvas. Any thoughts would be appreciated!
