I work in a service bureau that does wide format printing.
We do wall paper on 2 different Intelicoat produsts with a Canon Ipf9000 or an Encad Pro 600e with pigmented inks.
The Intelicoat meida we use is either DMiBOP10, or Mural Pro. They come in rolls up to 60" wide. They are put up using standard adhesive and method.
Here is a link to the web page
http://www.magicinkjet.com/ search the products and you can get a data sheet that gives the specs and hanging method.
Most of our clients prefer either we print to 36" or 42" material because it is easier for them to hang.
