Cheap Banner or Just a bad roll?

unsure about the banners changing colors.
I know lamination changes colors with UV burn, but never that uniformly.

Where these banners printed from the same roll or from a different lot #?


you list "Southern Utah"
that got me craving a Croshaw's Pie

 

It could be a low-cost PVC that doesn't have UV resistance.

 

Does look like a bad batch of material or you somehow managed to install directly under one of the last remaining holes in the ozone layer.

 

"That's just the banner telling you to buy a new one."
But really, don't tell the customer that.

 

That looks like bore water damage to me. I've done signs at golf clubs that turn that colour in no time because they're within range of the sprinklers, all of the other signs are still perfectly white that aren't within range of the sprinklers.
