Last year’s Seybold Publishing Conference in San Francisco was the setting for a major battle between Quark Inc and Adobe Systems Inc, following Quark’s unsuccessful attempt to acquire Adobe, and the first demonstrations of Adobe’s K2 Quark killer application, which is now shipping as InDesign for a price tag of less than $300. Both Adobe and Quark have booked press conference facilities for this year’s show, which begins next week, along with Xerox Corp, Apple Computer Inc, Canon Inc and Eastman Kodak Co. Apple’s Steve Jobs is the keynote speaker on Tuesday morning, and Adobe’s president and chairman Charles Geschke and Quark’s chairman and chief technology officer Tim Gill will both be on the same industry panel discussing next generation tools at the Wednesday morning keynote.
