DENVER – March 29, 2005 --Quark Inc. today announced its membership in the Ghent PDF Workgroup (GWG), an international assembly of graphic arts professionals established to create, test, and disseminate best practices and specifications for publishing workflows. “Ghent PDF Workgroup has done an excellent job in creating PDF output specifications for real-world production environments. The significant level of real user involvement in Ghent PDF Workgroup is the reason Quark joined. We’re dedicated to supporting industry open standards that are important to our customer,” said Jürgen Kurz, senior vice president of product development.  “As an active member of the Ghent PDF Workgroup, we look forward to communicating with representatives of the global graphic arts community — not only about today’s specifications, but also about future standards and practices that will shape the graphic arts workflows of the future.” Quark is key addition to vendor member roster Saskia Desmet, GWG executive director, said that Quark’s membership in the GWG is critical and highly appreciated. “Quark is an integral part of the publishing landscape, and no publishing consortium is complete without its participation,” she says. “Quark’s valuable input, representing its years of experience and the interests of vast numbers of PDF publishers, arms the GWG with tremendously helpful, relevant data for the world’s PDF community.” As a result of Quark’s anticipated contributions, GWG will be able to develop more comprehensive specifications and best practice guidelines — and all more rapidly.
