 When you're happy with your poster, save it as a PDF and make an appointment with the Student Technology Center. They've got a large sized printer that can print your poster and every Western student gets one free big print. To ensure everything is visible on your poster and that it's absolutely ready, you can ask a studio assistant at the Hackerel Research and Writing Studio, which is right across from the Student Technology Center, to take a look at it, or one of the student employees at the Student Technology Center. It never hurts to have a second set of eyes on your project before you commit to using your one free big print.
