I've been trying to export a pdf for print and illustrator has decided to put this blue line around the artboard. I can't sent it to print like this because the blue line prints. Can't seem to get rid of it. Please help!
Thanks for reaching out and sharing the details. Could you please confirm which version of Illustrator and operating system you're using? When exporting, make sure that 'Use Document Bleed Settings' is selected in the PDF export window under Marks and Bleeds, verify that Trim Marks and Registration Marks are unchecked.
If the blue line still shows up, please share a screenshot of your export settings, so I can take a closer look and help you further.
