Due to Illustrator’s inability to Warp linked images and my unwillingness to suggest you embed raster images due to editability problems, we need a secondary approach for raster artwork.
Sometimes you aren’t provided a dieline, just a package sample. It’s quite possible to create curved artwork without a target dieline. You’ll need a physical sample of the package to measure. And make sure you have some string. I’ll explain later.
I received a response to a comment I left on a LinkedIn post. It was the genesis of this multi-part tutorial on Curving artwork to fit to cups or fitting a curved supplied dieline.
