QuarkXPress lets you create a wide variety of materials quickly and efficiently from within an intuitive, standards-based environment. This premier electronic page-layout application provides you with software solutions to meet your publishing needs.
Building on existing tools to facilitate digital workflow and multipurpose publishing, QuarkXPress 4.1 includes improved support for PDF, scripting, and Internet publishing. Some of the new features include PDF Import QuarkXTensions software (import pages from PDF files created with Adobe Acrobat Distiller 4.0 into QuarkXPress picture boxes and print high-resolution output, as you would any other graphic); PDF Export QuarkXTensions software (output PostScript files optimized for use with Adobe Acrobat Distiller 4.0, with the option of distilling your file immediately or saving it as a PostScript file that can be distilled later); and HTML Text Import QuarkXTensions software (import HTML text into QuarkXPress text boxes, the same as other text formats). You can also author XML content easily and efficiently; generate high-resolution image previews; use the new Scissors tool to cut text and picture boxes, lines, and text paths; use custom bleeds to specify a bleed value for each side of a document; and more.
