Quark has released a free book on how its Quark Xpress 7 desktop publishing system can be integrated with rival Adobe's Creative Suite 3 (CS3) design suite.

The Adobe suite includes the Indesign desktop publishing module that has been slicing into Quark's once overwhelming market share.

CS3 also includes the market-leading Photoshop image editor and Illustrator design modules, both available as standalone products and commonly used alongside Quark Xpress. So are Adobe's Flash and Dreamweaver web design products.

Adobe claims the tight integration of CS3 products as a major reason for choosing Indesign over Quark.

But Quark says Xpress 7 has "better integration with Photoshop and Illustrator tools than ever before" and its Interactive Design can output Flash files directly from Quark Xpress 7.

The Quark book, available for download here, claims that Quark Xpress 7 works with CS3 as well as Adobe's products and " offers a host of exclusive features" as well.
