I've been doing some Tyvek tests on several Epson, HP and Canon printers and have several prints on the roof of a local museum that are exposed to the brutal Texas sun, rain and hail. Canon sells a Tyvek that's quite affordable so I'm using theirs for the tests - but I suspect that everyone has the same Tyvek product that's simply rebranded. The durability of Canon's new x300 inks shows up but more importantly, the need for a over laminate presents itself. With all the print tests, the ones that are coated are holding up great and look like new. There are a bunch of liquid laminates and all the water based products are comparable, IMO: ClearStar Type C, Eco Print Shield and AquaCryl. Combined with the coating, the gamut is pretty darned impressive for an outdoor product. Coated, I'd say that this is a great option for fairly short term outdoor usage.
