Preview The Beta of Markzware’s
Patented World Preflighting Standard

RIJSWIJK, The Netherlands ­ 27 March 2007 — Markzware, preflighting, and data conversion software leader, releases today, as a preview of Markzware’s patented world preflighting standard, the public beta of FlightCheck v6 with QuarkXPress 7.

Markzware’s CEO, Patrick Marchese states, "Many print and publishing workflows use and depend on FlightCheck as their comprehensive preflight solution for quality control. The FlightCheck 6 beta for the Macintosh has been issued to key accounts for testing since last November. We have found their comments very helpful. This public beta signifies that Markzware is very close to a release. We expect to ship in early to mid-April and welcome any comments and suggestions."

Markzware is delivering a widely available FlightCheck beta to allow customers an early chance to preview and test another great Markzware release.

FlightCheck 6 Features include:

Refined Interface
Includes automatic FlightPlan switching between PDF and Native files. No more setup required to tap into the FlightCheck PDF preflighting capabilities. Now when you preflight a PDF file, FlightCheck will automatically switch to the PDF rule sets. If you then preflight a native file like an InDesign or Quark job, FlightCheck will automatically switch back to the preflight rule sets for native files.

QuarkXPress 7
FlightCheck 6 is now Universal Binary compatible for Native Macintosh Intel machines and allows users to preflight QuarkXPress v7 documents from a single and central stand-alone application.

Support for Third-Party Font Applications
FlightCheck 6 supports popular Font Management Tools, such as Extensis Suitcase Fusion, InSider Software Font Agent Pro, Linotype FontExplorer and Apple Font Book.

Automatic Subfolder Creation When Collecting
This new version automatically creates Fonts and Images subfolders whenever collecting jobs for print.

Enhanced Font Searching
Users have the capability to setup customized font paths for prioritizing where fonts should be searched for first.

Enhanced Image Searching
Users have the capability to setup customized image paths for prioritizing where images should be searched for first. Additionally OPI detection for Color Central has been enhanced.

PDF Preflighting
FlightCheck 6 now offers optimized performance and accuracy with PDF (v1.6) files and offers automatic switching of preflight rules.
