How to set PSD link in illustrator to overprint?
I'm currently setting up some packaging artwork in Illustrator 2020 which requires layers to be set to overprint. On one layer, I have an image of some grass which is linked as a photoshop file. This needs to be overprinted onto the layers beneath but the option to select overprint is greyed out.
I am able to select overprint for all of the vector elements in the file. It's only the PSD link that I am unable to select overprint for.
Cheers
