How do perforated window film stickers work?

There is enough print surface area for the image to appear solid from the outside, with a subtle opacity and then appear tinted on the inside. There are little holes in the film creating a mesh look when you look up close. The size of holes is what creates the different levels of transparency. We offer 2 types of perforated film: 50/50 or 70/30. The first number refers to the amount of printable space and the second number is the amount of open or see through space. 70/30 film has more print space and less see-through space making it harder to see through. Whereas 50/50 has less printable space and more see through space.
