Hi Bob - I went through a bunch of the videos, but none seemed to show any sort of basic intro to DPS. I learned about how well it integrates with InDesign CS5.5, about single and multiple folios, about the basic workflow, etc. But everything seems to assume that I already have it. Can files created with DPS be used on websites or only mobile devices? Do people need apps on their mobile devices to use files created with DPS?
DPS is for mobile devices only.
DPS makes an app that people download to thier device just like any other app.
