I'm designing a vinyl decal to cover the whole back window of a Jeep Cherokee. I got the dimensions from corner to corner, but when it was printed there was a massive 'rainbow' curvature of everything, apparently due to the window having a sort of outward bow to it (which may or may not be greater at the bottom than it is at the top).
I've done a couple car decals before and haven't had a major problem, but this one has text stretching all the way across.
Starting from the flat car template in Illustrator, had to arc-warp the art -16º to even kind of approximate the areas that were cut off in the final print.
Does anyone know of a decent solution for making this kind of vinyl appear like it's going straight across a curved surface like this?
I don't understand how it could go from that to this (or how to correct for it without modeling it in 3D with UV coordinates or something crazy I don't have the tools for...?):
Edit - For clarification: I am not the person applying these decals. I'm the art director for the Barker Lounge. I live and work in a different state from the franchise that's getting this put on their car, and I don't have access to the vehicle. When we saw the results we got a guarantee that they would redo the job. But before that, I want to make sure we are providing art that won't cause this bend/arc issue...
