I was asked to do a Billboard design that is 10 X 22 feet for a fashion brand that I'm interning for. I do not have experience in this kind of stuff, I use AI for fashion flats and vector illustrations, I don't do print work. I did do 2 posters for the internship, but that was easy because I used a template and just added the art work, they came out beautiful!
However, this time, I was unable to find a 10 X 22 billboard AI template. How to set up the document, what numbers do I plug in and do I use inches or centimeters?
Also the images I'll be using is a 150 resolution, is that ok? Don't they need to be 300 dpi?
