This is not the only thead on this matter.
I want to print in a polyester based ra4 materiaal at home.
I know fuji offers fujiflex, ilford ilfoflex, an kodak duraflex (although they might have changed the name allready, I don't know). I believe ilfoflex is also called ilfocolor 
Does anyone, knows where to get any of these 'papers', I don't care which one. I am located in europe.
I only found one company called "calumet photo" from usa that has fujiflex but they ask 155 dollar sending. There must be someone in europe printing on a flex material right?
This is my last attempt... I hope for good ideas. Other wise I am affraid I have to go and place an 500+ dollar order at calumet...
