And it looks like everyone's go-to will be ours as well. Kinko's offers some unbeatable prices on large scale printing and gives you options like printing to canvas. Since we can lay something out ourselves in Photoshop or Illustrator, we can make sure that we have enough resolution to blow the image/text up large without it becoming grainy. And since what we have in mind would stay black and white, we can even use the large scale copier they have for doing blueprints.
