Ben,

It is a very short summary, nothing more than the usual research 
"poster". I tried to find the real article but couldn't.  My main 
concern is the vacuum oven. That is a very rough method which heats the 
media but also dries it to unnatural levels. I have seen it used for 
roofing materials etc. I suspect that the RC polyethylene layers loose 
their flexibility fast and components of the Gudy mounting material 
create "solvent" bubbles in between the RC and the aluminium surfaces of 
both mounting board types. Both will not happen with a pure paper base 
print. If humidity would be varied instead the pure paper print may have 
more issues than the RC when mounted on aluminium. Not to mention the 
protection against abrasion.  I am not in one camp and so far have only 
used Photorag prints mounted on aluminium and DiBond.

Yesterday I did send a PR print to the lamination shop for mounting on 
aluminium, repeat job, a profile on the back of an aluminium mounted PR 
print was not glued properly and the print fell on the floor after 6 
years. No complaints about the print quality, a Z3100 product, or the 
mounting method.
