from a previous post:

JPEG files cannot go over 2 Gig or 65535 pixels wide or tall.

JPEG cannot go over 30,000 pixels wide or tall in Photoshop (due to some code that's proven difficult to replace).

What other formats can your commercial printer handle, to produce that adhesive image?

I would explore others, than JPEG, per Curt's stated limitations.

Good luck,

Read up on the requirements for such stuff and how people are actually gonna use it. Nobody does (car) stickers at 300dpi. I really strongly suggest you read up on that stuff and that old resolution vs. pixel dimensions vs. physical dimensions... You have only made your life difficult by creating such a humungously large file for no apaprent need...

1st you need to download superpng extension in SuperPNG

merge all your layers

change the cmyk to rgb

then save it as superpng.
