Workflow - JDF

Manufacturers of hardware and software, e-commerce vendors, industry associations, and important printers are currently working together to create an efficient, fully automated end-to-end printer supply chain lock workflow.
In April 2001, before the International Press, the Printing and Postpress Processing Technology Integration and Cooperation Association (CIP4) announced the JDF1.0 operation specification. JDF is a NEW open operating standard for the printing market launched by Adobe, Agfa, Heidelberg and Mann Rolland in 1999. CIP4 is responsible for the promotion and application of this standard.
Although JDF has not been formally established as an industry standard by the American National Standards Institute (ANSI), JDF will soon become the official standard. In fact, many supporters have regarded JDF as the operating standard.
JDF is a current job ticket specification that is fully compatible with Adobe's portable work ticket format and has PDF workflow capabilities and XML automation technology capabilities.
Automating the work process The JDF standard enables automation of job and asset management, pre-inspection preparation, imposition, trapping, RIP processing, plate making, printing, and finishing and binding. Using the JDF standard, the Intent Resources language used to describe the output content can be determined without knowing the production equipment. The JDF supports general and specific descriptions. For example, the No. 1 hole adopts a three-hole reamer and simultaneously determines the shape and size on the XY coordinates. JDF also supports data ranges such as customer specifications for textbooks with a basic weight of 50-60 pounds.
JDF operating standards can benefit both printers and their customers because it simplifies the job specification process, enables print sales to accurately state the requirements, and automates many of today's disparate production processes with flexible and versatile job tickets. . What does this mean for printers? Mr. Jim Makis, Group Vice President of PrintTald (Print Forum), said: "The current press shop needs to use multiple devices to complete a job. Some devices can be connected with other devices in the workshop. But from the document production The entire system to print output is not an organic whole, and each device is like an island in the water."
Using JDF operations to connect the bridges of various "islands", the entire print production process (from customer orders to print output) is equivalent to an organic part of an end-to-end production system. In addition, JDF can also link MIS job planning and control systems with production services, which previously had no way to communicate with each other.
“The JDF can shorten the print production cycle and represent the future direction of the digital workflow from a production and sales perspective,” said Wayne Mins, senior engineering application technology manager at NexPress Solutions LLS. Of course this requires the manufacturer to JDF operation standards are used in the production process.
Show all the information Mr. Mülls said: "Why is JDF so important to NexPress? When we use digital automated workflows, we need to display all production and processing information needed to produce jobs. To reliably reproduce graphic content (using PDF, or PPML/VDX Open Variable Data Exchange Standard using PDF-based and on-demand printed personalized print markup language)."
Mr. Mins also said: "In variable data printing, a job may have thousands of customers, and each customer has different requirements for the length of print, graphic content and finishing processes. We need a digitization. This is exactly where JDF comes in. JDF stands for production control and provides an effective solution to the automatic processing of information in the production process."
Martin Bailey, Harlequin's senior technical advisor, said: "JDF can greatly improve the end-to-end operational efficiency of print production workflows and enable open systems to be perfectly combined in the entire high-efficiency, high-yield production process."
Mining application potential The PrintTalk job standard has enabled JDF's application potential to be further explored. This standard was introduced immediately after JDF.
Mr. Makis said: “The JDF solves the problem of production orders, and PrintTalk addresses the digital management of customer relationships and contact communications. The JDF operating standards relate to the number of pages, the type of paper used, the number of colors and the location of use, and binding. The type, etc. PrintTalk job criteria are related to quoting, the type of currency used, and order change matters."
The initiators of the PrintTalk job standards are companies that develop business management systems for printers and companies that provide e-commerce solutions. Their purpose is to seek a common language of communication.
The general standard has not yet been booked Mr. Makis said: "There is no general standard used to describe the printing and sales business. So we launched our own product." PrintTalk supports the use of JDF and CXML. CXML is a commercial version of XML. There are some large companies in the world that use this markup language to conduct business transactions on the Internet. Like JDF and CXML, the PrintTalk standard is free for users to use.
The influence of the digital printing production line JDF is not limited to the above-mentioned links. The UP3I, a printer pre-processing and post-processing interface, is the latest operating step for the binding job description interface for all aspects of an integrated digital printing line. The basic concept of UP3I was first proposed a few years ago by some important manufacturers, including companies such as DUPLO, Hunkeler, Oce, IBM Printing Systems, and Stralfors. The basic function of the UP3I is called "smart linking". Its role is to connect digital presses and on-line, near-line prognostic processing and processing equipment.
The Joint Working Group of JDF/CIP4 and UP3I is working hard to integrate JDF with UP3I organically, and 1.0 operating standard will soon be released. Technical demonstrations are currently in progress.
Mr. Makis said: “JDF will change the future of printing production because it can increase production efficiency and eliminate many errors. In the near future, printers will seriously consider the production equipment using JDF operation standards. In a few years we will You will see that many news reports will talk about the JDF standard.
