I need to create a 24" by 36" poster that will be printed by a company with a poster printer.
I've never created anything like this before and was wondering what program I could/would use (hopefully free) to organize the various graphs/images/text on to be able to send it to the company to be printed.
I believe the file I need to send them is a 'high res PDF' but idk how/if I can lay out the poster that way.
fg for tips/help!
