Jan,

cutting a film to verious formats really isnīt a big deal.
We will provide standard formats out of stock and offer special formats cut on demand.
With the cut on demand sizes it will be in a way that one box will cost almost the same as 5 boxes and after 10 or more boxes it gets almost as economical to buy this product as if it was 4x5". This reflects the actual manufactirung costs and is a very small quantity. You can then maybe team up with others and split the order if you need full plate or somthing else unusual.

Best regards,

Mirko
