There are 2 products here that we could be discussing.
I am not sure which you are speaking about.
Are you speaking about using Arbortext Editor, Arbortext Styler and the Arbortext Publishing Engine,
or are you speaking about Arbortext Advanced Print Publisher?
Both systems handle graphics, tables, large indexes, landscape and portrait pages and large 1000+ page documents well.
Your best bet would be to speak with a PTC sales representative, so that you can define your current applications, flow process and desired goals.
