Now that desktop publishing king Quark Inc is at its most vulnerable as its core Macintosh business starts to dwindle, Adobe Systems Inc is coming out fighting with a new scheme to help switch Quark users over to Adobe PageMaker more easily. As part of the new promotion, Adobe is offering a new QuarkExpress document conversion utility, along with discount pricing for users of competitive products, free technical support, and a CD ROM with product and technical information. The package comes with a tryout version of PageMaker 6.5 for Macintosh and Windows. QuarkExpress Converter 3.0, an update to version 2.01 that shipped on the PageMaker 6.5 CD-ROM, supports the conversion of single files or batches of documents created in QuarkXpress version 3.1 or later. The package is now available free for trial versions.
