It sounds a bit ironic, the printing industry is in the communications industry, but we are painstakingly communicating the communication between our business and the production process. Bad communication often leads to additional work burden, delays in delivery cycles, and Increase production costs.
How can we facilitate the integrated communication between business and production and realize the digital workflow? JDF (job description format) and JMF (job message format) are the solutions. JDF is a format based on XML (Extensible Markup Language) and is recommended as an industry standard. Based on the existing technology of CIP3's PPF (Print Production Format) and Adobe's PJTF (Portable Work Label Format), according to the official description, JDF is available for administrative management and subsequent production execution components can be mutually The converted data format, from management to production, combines the resulting printed products.
JDF provides a way to describe a print job's production process, so this format allows the user to clearly indicate the necessary controls for each process.
JDF has three significant advantages
1. It standardizes the pre-press, print and post-press formats of any printed job;
2. It bridges the gap between production and processing services and management information services (MIS);
3. Regardless of the site structure or production method in which the print job will be completed, it can achieve both functions.
Adobe, Agfa, Heidelberg, and Manroland have jointly undertaken the initial development of JDF, but since the fall of 2001, JDF research and development work has been handed over to CIP4 organization (the successor of CIP3, the headquarters is now in Switzerland). ).
JDF version 1.0 was launched in April 2001, and the new version has been successfully developed and will be launched one after another. Regardless of the old and new, JDF developers will always ensure the convenience and compatibility of JDF, and have already adopted it. PPF and PJTF are reassuring users of the basic solution.
JDF is different
JDF is quite different from some of the standards or specifications that have emerged over the past few years. PDF and TIFF-IT are issues related to document formats. SWOP, GRACOL, and SNAP provide a guiding outline for printing features to ensure collaboration within the facility.
TIFF-IT, PDF-X and SWOP are all developed into official standards under the auspices of national or international standards groups. On the other hand, PDF and TIFF have evolved from proprietary technologies to de facto standards.
JDF is a more effective and great solution by accommodating many different standards or specifications. Be the best example of this. It is the wisdom of Adobe, Agfa, Heidelberg and Manroland, as well as CIP4, IFRA, Fraunhofer Major contributions from large groups such as IDF and PRINT Talk. The result of these joint efforts has made JDF a formal standard in a little more than a year, and this achievement is striking compared to the fact that most standards are built over the years. At the same time, it also proves that this unprecedented international cooperation is exactly what the industry needs. After only six months of approval, JDF has already played a major role in new product development. Meta as Heidelberg Dimension and Agfa's Apogee Series 3 workflows are adapted to the JDF standard. So far, not only most major printer manufacturers have applied such software in the control of ink fountain keys. In the post-press period, some nailing machines and cutting machines can also be automatically set according to CIP3 files, including folding and cutting. Automatic positioning and so on.
Can be further expanded:
Since JDF is based on the XML language, and XML is a scalable standard format that is controlled by 3W Group for many industries, JDF can be further extended for the development and exchange needs of the industry. The CIP4 Group has signed new cooperation agreements with them to further ensure the compatibility of standards.
CIP4 has more than 100 large companies, 73% of which are suppliers and the remaining 25% are applicators. During the Chicago 2001 Print Expo and the San Francisco Seybold Conference, public meetings were held to allow users to post feedback and brainstorm ideas to further eliminate inadequacies or omissions.
JDF will play an important role in achieving a fully automated printing workflow. Of course, it also needs to make individual adjustments based on the user's specific workflow requirements and the structure of the production system. For suppliers of different equipment or systems, it may take some time for them to make necessary hardware and software integration adjustments for current or future products. But in the end, JDF is not far from showing its benefits or power to achieve a fully automated workflow. For many years, the printing industry has been looking for a comprehensive solution that solves all the problems in the workflow. It seems that JDF is paving the way for this and is on the verge of success.
