The printing plant has formed two very obvious trends in response to market demand and its own production process due to computerization.
- Shorter production cycles and fewer prints.
- Prints involve more different processes, from prepress, printing to postpress, from conception to delivery, forming the entire production chain.
In order to cope with these two obvious market demands, no matter where you are, no matter where you are, a more flexible, more standard and less error printing process is provided by a more automated and highly transparent production process. The workshop is a must.
It is difficult for the various parts of the former workshop to compete with the production line of the three-dimensional management team, as the automation management can provide the current status of each part and estimate the next step so that all parts of the work can closely take care of the previous step and the next step. One step of production needs.
When the goal is clear, the next step will be an electronic work order. Simply put, it communicates with each production department through the computer system, tracks and guides the status of each print in each job, and manages all the prints from receipt to delivery.
The obvious biggest problem is that the machines of different manufacturers have different degrees of electronicization in different processes. Therefore, when the whole line is integrated, it is inevitable that the third-party suppliers should coordinate with the third party to make a reasonable next step.
On the other hand, general data and production process systems (MIS, Management Information)
Systems) have one-way command and post-data analysis power, while the multi-variable strain response still maintains manual assistance, so the immediacy and predictability are very low, and most of the computer engineers who design these production software do not have print management. Cognition.
Through the efforts of the industry, we have developed our own platform for the printing industry. The JDF format defines a series of things that enable unrelated units to communicate and be managed organically on the same platform.
What is JDF?
Simply put, JDF is an industry standard recommended in XML language to guide software manufacturers and printer manufacturers in the communication system reserved for system design.
-JDF is designed to allow software and hardware to communicate.
-JDF is designed to be used throughout the entire process, from media, design, production, warehouse delivery and more.
-JDF expects each part to have two-way communication.
In fact, JDF is not the application software itself. The printing company will eventually buy the production tools containing JDF functional standards from major hardware manufacturers. However, if you want to exert its management power, you need to add a JDF-based automated process software.
Currently, PDF (Print Production Format) and PJTF (Portable Job Ticket Format) are fully compatible with JDF. Because XML has strong development and vitality, JDF itself is also an agreement with strong development potential.
JDF supports production continuity
Since each hardware manufacturer supports this agreement from the plate making to the post-processing machinery factory, the two-way communication of each component should not be a problem.
JDF can also make presets in MIS or plate making liquids to make the entire production smoother and faster.
JDF also supports color management systems.
JDF can also strengthen production management in MIS.
JDF supports valuation and cost control during production.
JDF supports valuation and cost control during production
JDF has the ability to monitor material consumption, so that you can instantly know the consumption status of various materials on the site and compare the estimated values at the time of valuation.
It can be more systematic when ordering, so that the time of downtime and the like can be shortened, and the insertion order is more flexible.
JDF also realizes online two-way quotation and receipt
JDF's powerful online functions enable XML to communicate with the MIS system on-line.
JDF also allows customers to report information online.
JDF also allows the relevant production data of the customer base to go online.
Realistic application
Imagine a magazine printing house where different magazines print at different times, and each magazine has different content such as advertisements and text editors, different drafting requirements and delivery receipts.
In Europe, there is a printing plant like the one that uses a JDF-based management production system. The electronic file automatically edits the raster process from different sources, automatically recognizes the magazine book number and then automatically rasterizes it, automatically prints and arranges the delivery system to track the confirmation of the manuscript, automatically spells the version, and arranges the printing time. After tracking and confirming, it automatically Great version, and arrange printing time, tracking post-press processing and delivery receipt verification.
Not only the production automation, but also the administrator can know the production status of each magazine and the status and status of each department in the factory in real time through the computer.
to sum up:
Because of the promotion of CTP, the next wave will be an electronic management system driven by major suppliers. Many starting points are from PDF and JDF.
The 2004 conference is a time worth paying attention to. The German exhibition has exceeded 10,000 CTPs worldwide, and the JDF 2.0 version is officially launched. Relevant software and hardware have been introduced. I believe it will be a wave after the 1997 CTP boom.
