Laminated window perf looking hazy

Hi all, my first time posting here!

We started laminating rear window vinyls to prevent rainwater from accumulating in the holes and obstructing the view.

However, when installed you can't see through it - looks super blurry like in the photo.

Any suggestions as to why this could be happening? Printer claims he used clear lamination on the vinyl.

I'm in London, so "few days in the sun" method is out of question...

 

Spoke to the printer, and he confirmed that he used a normal clear laminate, not Opti-Clear. Looks like we'll need to re-print the rear stickers and install these separately.

It was dry installation, so shouldn't have been a problem.

Thanks for your help!
