Your definition of “document composition” will largely depend on your perspective.
A graphic designer might immediately think of Quark Express or Adobe InDesign. A desktop publisher could probably name various plug-ins to those environments or perhaps list database-publishing tools like Corel Ventura or Adobe PageMaker. If you are approaching this question from an operations, IT or print production perspective you have a much longer and more granular continuum of needs which can only be met with high volume composition software. In my work, I deal with both ends of the continuum from the graphic designer to the high-volume output specialist (see www.ArtPlusTechnology.com)
