Hi all. I'll be working with some multiple printing techniques coming up soon and I wondering what the best methods are for gluing paper to aluminum sheet (or perspex or acrylic sheet and other rigid surfaces). I've searched the forum but haven't found much in detail on this. I have lots of information referring to Irving Penn bonding paper to aluminum sheet using a few different materials. Also, I've watched the videos on this PAGE which shows the printer using diluted PVAc adhesive. The problem with these videos is that they dont give any insight into how to properly remove the paper from the aluminum sheet when the printing is done. For those using PVAc adhesive to bond paper to aluminum, how do you go about seperating the paper from the aluminum when you are done printing? If not using PVAc adhesive, what adhesive are you using? I've read that one of the Penn techniques was to drymount the paper to the aluminum sheet in a dry mount press which could then be seperated from the aluminum sheet when he was done by reheating it in the press. Thoughts on this? Are those of you who are using these bonding techniques using aluminum or other rigid materials? I am in need of a rigid material that I can punch for registration purposes and aluminum seems the best option so far. Any insight? Thank you in advance for your help!
