I have 12.5" and 8.66" in stock used on the Dedy 220mm and 320mm enrobers.
Have you tried Harold Guttman? I think you have to get a full case from him, but he deals directly with mills and he will send you samples of possible papers before you commit to a large order. His contact info:
I am jealous of your SELMI;
Mahalo, I'll give him a ring.
thanks for the info
I have a perfect enrober and buy paper rolls from them when I need to. Perfect does a lot of custom work so most likely they would be able to create what you need based on your specifications. Good luck.
Dredge this thread up for other ideas. Not really wanting to invest in a case but I'm sure shipping from Quebec (Perfect enrober here) won't be the most cost effective or expedient to Stateside.
