Can the artwork print to the edge of the page?
Yes the artwork can run off the edge of the sheet, your file should be setup with a .125 bleed. If unsure please download our poster template.
Should I submit a .jpg file to get the best possible print quality?
Although, we could produce a poster from your .jpg it will not be the best it could be. Our suggestions to you is that you create a .pdf from the program that you originally designed the artwork in.
What is the best way for me to get my message out to my audience now that I have printed posters?
There are many great ways to get your message out. First ask your various community members if they would be okay with you putting up a poster in their business. However if that all seems daunting you could contact out postering department at firstname.lastname@example.org to discuss your options.
