To make it easier to bind pages and to speed up the printing process (and thus lower its cost) printing presses do not print a single page at the time. In one single go a press may print 4 pages, or 16 or even 96.
Imposition is the process of working out how to arrange the pages on the press sheet so that the pages appear in the correct order after the press sheet was folded. This used to be a manual process but nowadays it is handled by software.

Selecting an imposition application based on its popularity would however be a wrong decision.
