- I forgot who posted the message about mounting pictures to foam
- core causing it to warp. I would like to know more information on this.
-
- Because I switched over to mounting my pictures on acid free foam core
- because I have several prints framed by custom print shops that have
- actually warped (the backer board where the print is glued looks like
- /\/\/\/\/\/\/\ creating an ugly picture. So I started my own framming
- and matting, using acid free foam core as a backer board.
-
- It has been my experience that a frame shop unless specially requested
- will mount the picture on regular mat board, which will warp in just a
- couple of years. The mat board is not rigid enough to remain straight
- over time. thus you must use either foam core to support the matt or a
- corregated mat to support it, or just mount the picture to the foam core
- itself. So, since the foam core is acid free why not mount the picture
- directly to it?
-
- Here is how I layer my pictures if it helps.

- ***** actual picture frame
- ===== glass
- ----- mat board, 2 layers
- """"" art work/ picture
- ..... glue (3m PMA)
- ||||| Foam core backer board
- ~~~~~ craft paper (to help seal the frame)
-
- So here is my big question?
- why not use the foam core to mount the picture to. It is much stiffer
- than mat board, thus resist warping several years down the road.
-
- And even if you do use mat board withthe special coragated backer board mat
- what is to prevent the print from warping forward (towards the glass)?
