I am trying to create a large banner in InDesign. The banner features lots of text as well as some graphics (tiffs) I'll be pulling in. Once it is printed, the banner will be 167.25" x 47.25". Soooo...I originally created an InDesign document that is 167.25" x 47.25", but have since realized that this may have been a mistake (Photoshop won't export tiffs at that large of a size). Should I have made the document proportionately smaller? If so, how much smaller? Is there an easy way to scale down an InDesign document? Maybe a better question would be "Could anyone give this novice a step-by-step walk-thru of what you would do to create a banner this size?" I would GREATLY appreciate it -- I'm on a time crunch.
