Some feedback
Hi,
Well my first attempt at gluing paper to aluminium failed dismally. I attached a piece of cot320 using a local PVA adhesive full strength straight from the bottle by rolling the adhesive onto the metal then placing and rolling the paper onto the glued surface. It went on beautifully. Nice and flat, no bubbles, perfect. I applied the first coat of gum and developed it no problem. Second coat I noticed slight lifting around the edges of the paper but nothing significant. As I developed the third coat the paper lifted completely off the paper. I used brush development for that image so the print wasn't in the water for an extended time.
Second attempt I used the same mounting method but left the glue for 24 hours to harden. I developed three coats on this image after this it was finished so I left the print in the water (in my bath) to loosen the PVA. That was three days ago. It's still underwater as I type with absolutely no indication that the thing is ever going to loosen. One slight detour to my workflow was that I exposed the completed image for 5 minutes under the UV lamps. The print darkened slightly but the long soak has restored the colour and none of the pigment has been lost from the print over the last three days.

The tests continue. Maybe a weaker solution of PVA?:confused:
