Along with other performance enhancements, QuarkXPress 6.1 includes support for Mac OS® X v10.3 Panther. QuarkXPress 6.1 features improved integration with Microsoft® Excel. Users can import text, picture, and chart data directly into QuarkXPress 6.1 from an Excel workbook. An entire spreadsheet or a range of cells can be imported, and QuarkXPress 6.1 respects formatting information such as borders, colors, patterns, and backgrounds, as well as hyperlink data contained in the spreadsheet. The Edit Original XTensions module gives Mac OS users the ability to select a picture then open and edit it in a preferred image editing application. A new font mapping utility lets QuarkXPress 6.1 users create and manage rules to govern automatic font substitution. Font substitution rules can be imported and exported, so rules can be shared among multiple users. Font mapping rules can be applied to QuarkXPress projects and project templates as well as legacy documents and templates.
