We've tried to make it as easy as possible to prepare your large sign, but you should be sure to give yourself plenty of time in case something goes wrong. Here's what you need to do:
Step 1: Download the file:
Step 2: Send the file to a local printer: Click here to find the closest Kinkos and the store's email address. Send the poster file to the store as an attachment and then give them a follow-up call (you'll get an email with the phone number once you send the file). Ask them to make the document 48 inches long. It should cost $9 for the printing and take around 2 hours. Be sure to confirm this with them while you're on the phone.
You can follow the same basic process with any other local printer. It's great to support union print shops when possible. You can find local union shops here.
Step 3 (optional): Strengthen your signs: If you're holding your event in an area that may be windy, you can try strengthening your sign with some cardboard. All you need to do is cut two strips of cardboard to be about 24 inches long and tape them to the back of your poster on each end. This will give people something to hold onto. Make sure they're not visible to people in looking at the front of the sign—you don't want to spoil your visual.
