InDesign CS5 supports multiple page sizes within a single document! This new option allows your students to create various projects within one InDesign document by simply using the new “Page Tool”.
I’ve spoken to a number of DTP teachers who have their students design a corporate identity package as part of their curriculum.
An example assignment would look something like this:
- design an envelope,
- design matching letterhead
- design matching business cards
Prior to InDesign CS5 the students would have had to create an InDesign document for each project. Students can now simply create a single InDesign CS5 document containing three (or more) different page sizes!
