Hi Ernst,
I've tried some vinyl products like PhotoTex or Photo Peel Gloss but I've never heard of a Tyvek based printable media. Do you have any brand names? I'm in the US so I guess it might be different here.
Thanks.
Paul
Check Tyvek inkjet media and make sure they are not intended for (eco)solvent inks but aqueous inks. 36, 42 and 60¨ etc wide but no 44", sheets too, Dupont often mentioned.
http://www.materialconcepts.com/tyvek/banner-media/for example in the US but you have to test the image quality as there are variations in the inkjet coatings from different distributors. It has no sense to mention EU distributors, all relabeled stuff where the origin is hard to trace.
Met vriendelijke groet, Ernst
