There's been a flurry of activity recently from Quark's Denver headquarters. Less than a month ago, Quark announced its new App Studio, a module for the Quark Publishing System that facilitates publishing to the iPad for medium and large businesses. That same day, Quark made a variation of that software--called iPad Publishing Service for QuarkXPress--available to smaller operations that do not use the enterprise publishing system.

Quark's flagship product, QuarkXPress is currently at version 8.5 and runs on Mac OS X 10.4 or higher on either PowerPC or Intel Macs.
