JDF – JDF is a comprehensive XML-based file format/proposed industry standard for end-to-end job ticket specifications combined with a message description standard and message interchange protocol. JDF is designed to streamline information exchange between different applications and systems. JDF is intended to enable the entire industry, including media, design, graphic arts, on demand and e-commerce companies to implement and work with individual workflow solutions. JDF will allow integration of heterogeneous products from diverse vendors to seamless workflow solutions. Basic Idea upon which JDF is based: To develop an open, extensible, XML-based job ticket standard, as well as mechanism that provides new business opportunities for all individuals and companies involved in the process of creating, managing and producing published documents in the new economy. Building on existing technologies of CIP3’s PPF and Adobe’s PJTF, the Job Definition Format supplies a means for printing businesses to streamline the process of producing printed material. The most prominent features of JDF are: (1)Ability to carry a print job from genesis through completion. This includes a detailed description of the creative, prepress, press, postpress and delivery processes. (2)Ability to bridge the communication gap between production and Management Information Services. This ability enables instantaneous job and device tracking as well as detailed pre- and post calculation of jobs in the graphic arts. (3)Ability to bridge the gap between the customer’s view of product and the manufacturing process by defining a process independent product view as well as a process dependent production view of a print job. (4)Ability to define and track any user defined workflow without constraints on the supported workflow models. This includes serial, parallel, overlapping and iterative processing in arbitrary combinations and over distributed locations. (5)Ability to do so (1,2,3&4) under nearly any precondition.
