Answer
For rear window graphics, we provide an email proof with a pink line to demonstrate the rear window dimensions you have provided for your vehicle. The pink line gives you an idea of how the image will look when it is installed. The pink line also allows us to show you what parts of the image will likely be cut off when you install the graphic.
With shape or exact die cut graphics, the pink line in the proof shows where your image will be cut.
As for banners with finished edges (the “Outdoor” option), occasionally text or images will get cut off by the hemming or heat welding. In those cases, we will send you a proof with a pink line that shows you where the hem line will be so that necessary adjustments can be made.
