According to Macworld.co.uk, Quark is gathering the press for an official launch event for QuarkXPress 7 at the Congress Centre in London on June 2.

Quark has seen greatly increased competitive pressure from Adobe's InDesign in recent years. A recent Macworld.co.uk poll shows that consumers are split in general between the competing platforms.
