jdf是一种特殊的数据格式。 The specification defines the Job Definition Format (JDF) and its counterpart, the Job Messaging Format (JMF). JDF is an extensible, XML-based format built upon the existing technologies of CIP3's Print Production Format (PPF) and Adobe's Portable Job Ticket Format (PJTF). It provides three primary benefits to the printing industry. Unlike any previous format, it has the ability to unify the pre-press, press, and post-press aspects of any printing job. It also provides the means to bridge the communication gap between production services and Management Information Systems (MIS). And finally, it is able to carry out both of these functions no matter what system architecture is already in place, and no matter what tools are being used to complete the job. In short, JDF is extremely versatile and comprehensive. JDF is an interchange data format to be used by a system of administrative and implementation-oriented components, which together produce printed products. It provides the means to describe print jobs in terms of the products eventually to be created, as well as in terms of the processes needed to create those products. The format provides a mechanism to explicitly specify the controls needed by each process, which may be specific to the devices that will execute the processes. JDF works in tandem with a counterpart format known as the Job Messaging Format, or JMF. JMF provides the means for production components of a JDF workflow to communicate with system controllers and administrative components. It relays information about the progress of JDF jobs and gives MIS the active ability to query devices about the status of processes being executed or getting ready to be executed. JMF will provide the complete job tracking functionality that is defined by IFRAtrack messaging standard. Depending on the system architecture, JMF may also provide the means to control certain aspects of these processes directly. This document describes components of JDF, both internal and external, and explains how to integrate the format components to create a viable workflow. Ancillary aspects are also introduced, such as how to convert PJTF or PPF to JDF, and how JDF relates to IFRAtrack..." jdf作为打印和印刷也的一种行业标准，它已经越来越显示出它的优势
我主要是想通过讨论，使大家学得一点新东西。当然，我的需要还是第一位的。现在，手头上有一个打印库，是读jdf格式。所以我要.....
请大家帮帮忙！我浏览过的一些资料：
