Font issues when copying artwork from Illustrator to InDesign
Hi all,
I'm having some issues with artwork that I've copied from Illustrator to InDesign.
I created some exhibition banner artwork in Illustrator but the exported PDF was huge so I copied everything over to a new document in InDesign (not best practise I know, but I just needed to get it out the door!).
All of the text appeared to come over as vectors (not editable) but the printers came back to me and said that the document contains fonts that they don't have. So I've gone back in and sure enough, 'find fonts' is showing 256 fonts in the document (multiple duplicates of the same font). When I navigate to one of the instances I can't edit the text so it appears to be outlined. Here's a screenshot of the 'find fonts' window for reference.

Can anyone help me figure out what's going on please?
Thanks,
Lucy
