When I started out, I was really concerned with the restoration aspect, still am. But that is really after you've become proficient at washing and laying down a poster properly. A poster can only be restored correctly when it's been laid down on the masa and canvas well.
So, what are your washing steps, and what chemicals are you going to use in the process of the wash prior to laying the poster down. You'll need a chem list for washing, and the necessary steps to make the wheat starch adhesive as well. Post your list and we can help clarify what looks good, as well as your steps.
Here is a link to find great information on the treatment of paper.
go to the section on "Conservation Treatment" I printed out about 20 chapters and read quite a bit before getting a poster wet.
So is what I laid out a basic understanding? I'm sure I'm missing stuff.
