The origin of CIP3
The original concept was developed in December 1993, the first draft of the archive format was completed in September 1994, and the prototype for testing in December made the possibility of planning realization greatly increased, so 15 companies including Adobe, Agfa, Fuji, Kodak, MANRoland, Heidelberg, Polar and other suppliers of prepress, printing and finishing operations form an alliance. In February 1995, the company officially formed the International Cooperation for Integration of Prepress Press and Postpress CIP 3, dedicated to the development and promotion of three processes of the printing process. Vertical integration. By the end of 1995, a total of 39 institutions including computers, operating systems, software, prepress, printing and finishing equipment had participated, and it was another large-scale international printing research and organization following the ICC International Color Alliance. The format developed by the alliance has been developed by the relevant manufacturers of the alliance since June 1997. In the large layer of Drupa2000 printing, it can be seen that almost all printing-related software and hardware suppliers have already supported the CIP3 specification.
Purpose of CIP3
Over the years, the printing industry has developed the CIP3 process to fully computerize the prepress, print and postpress processes, turning all data into data and reducing human error.
CIP3 agreement main achievement - PPF
In today's printing trends, diversification, short-run, accurate color requirements, cheaper prices, etc., drive the printing industry to become electronic, thus avoiding any possible human error. For example, input of ink key data, cross positioning, and paper cutting, etc., all hope to be computerized, one step in place, so PPF came into being.
PPF, Print Production Format, is a computer data protocol format that enables a common electronic data format for different work platforms, making communication more straightforward, avoiding errors and wasted time in data transfer and copying. This led to the development of a concept - CIM (Computer Integrated Print Management), a fully computerized overall management.
The most popular thing about PPF is the electronic ink drop management. In addition, the following information can be generated by the electronic plate-making process depending on the function. The 3.0 version of PPF developed in 1998 can support:
Work order management data
Key data
Cross and color management ribbon
Roller printing operation data
Cutter and origami
Delivery
Nail style
The origin of CIP4
Due to the continuous development of technology, it is necessary to join the elements of administrative management and production management. Therefore, the “3P program” was innovated in 1979. But still use the abbreviation "CIP", and add a new element "Process", the full name is International Cooperaton for Integration of Processes in Prepress Press and Postpress, the English name literal translation is "integrated prepress, printing and postpress International cooperation organizations of various processes." Because it adds one more "P", it is called "4P scheme" (CIP4).
ClP4 goal
The goal of the Alliance is to develop a common set of open work standards for print file exchange and data sharing formats, such as the "JDF" print art common format. The members of ClP4 form a dozen working groups whose role is to identify and develop new JDF files, study the needs of JDF users, and design a JDF SDK (system development tool).
Definition of JDF&JMF
JDF, Chinese translation - Job Definition Format. It is one of the CIP4 development goals. JDF is a comprehensive, XML-based file format. It is also an open standard for job format descriptions in workflows, including the Information Description Standard (JDF) and the Information Exchange Protocol (JMF). For example, when JDF performs data exchange, the state of JDF in the process can not be timely response, and JMF makes up for this deficiency, which provides a dynamic interaction mechanism.
JMF, Chinese translation - Job Messaging Format. Mainly used to send and receive information. JMF can be used by workflows and management systems (and even other devices) to request equipment or provide processing instructions. MIS uses different JMF information management workflows. For example, MIS can send JMF information to a device and instruct the device to execute a JDF node. MIS can also use JMF information to query the status and function of the device or controller. There are many forms of sending JMF information: one is Hypertext Transfer Protocol (HTTP), which is the same as a web browser. The other is through the hot folder. Most products in the future tend to adopt HTTP as a form of transmission information.
JDF goal
JDF can realize smooth information exchange between different application software and systems, and realize the full application of digital workflow. Media, design, graphic arts, personalized service and e-commerce can be integrated into the workflow; Integration to achieve a seamless workflow solution.
Four characteristics of JDF
1JDF provides a mechanism for controlling all the processing required for a print in the production process. The JDF can accommodate a description of all the processing steps necessary to complete a print, which is accomplished by interpreting each of the processing steps in the job into code. Each code, each processing step, is defined based on code input and output. An input to the process, so the whole process is defined as a hierarchical network of processes. The process is connected by the processing of the input and the response to the output. JDF has the ability to fuse the individual processes together. In this way, each step becomes a part of the whole.
2JDF provides a mechanism and a complete communication mechanism that allows production automation systems to control, track operations. This includes messages between the production system and the MIS system and the JDF Enabled process so that they can communicate in real time. In addition, JDF itself contains information about the process that can be used for job tracking.
3JDF is a vendor-independent standard. When developing the first version of JDF, it was hoped that the feature file control would be handed over to a cross-industry association, in order to ensure that all vendors can use the JDF system, and no one vendor would be weaker than other competitors. JDF is controlled by the CIP4 organization and is also an open standard.
The 4JDF process can be flexibly configured. Users can assemble their own processes as if they were building blocks according to their own needs, and can flexibly increase or decrease the equipment parts in the JDF process according to their own needs.
JDF operation
The JDF process consists of the following parts
1 Machine (Machine), is the part of the process to perform any printing process. Generally speaking, it refers to physical equipment, such as a printing machine or a folding machine. Of course, it can also be a software part of the control hardware. If a computer workstation does not have a JDF interface, then whether it is automated or manually controlled, it is considered a Machine.
2 Device (Device), the most basic function is to be able to process the information assigned by the Controller and specified by the Agent. Device must be able to execute the JDF node and activate Machine to complete the physical processing. In order to dynamically interact with the Controller, Device can support JMF. Moreover, it can be placed in the machine or externally externally, and a kind of computer terminal device is used to tell the technician how to control the corresponding machine.
3 In the process, the Agent is responsible for rewriting or creating JDF jobs. Add nodes to existing jobs and modify existing ones. The Agent can be software, automated tools, and the like. The Agent can be anything that generates JDF. Most Devices and Controllers should have the ability to modify JDF, in fact they all integrate an Agent.
4 Control device (Controller), a device driven by JDF, can monitor and monitor each other between the device and the controller and transfer the information created and modified by the Agent to the appropriate Device.
The minimum requirement for the Controller is to be able to activate the process on at least one Device, or to another Controller extension. In other words, when the Controller has no control over the object, it is not a Controller. In some cases, multiple Controllers may form a pyramid structure, and the upper level Controller controls a series of low-level Controllers. But the lowest level Controller must be able to control Device. In the case where the Controller forms a pyramid, the Controller must work with other Controllers. In order to be able to communicate with other Controllers and Devices, the Controller must support the JDF Part Exchange Protocol and JMF. At the same time, the Controller must also be able to interpret the processing rules and measure progress data, for example, the processing time and the number of planned products.
In the process, the manager of all units is the MIS system. MIS (Management Information System) is actually a top-level Controller that is responsible for command and monitoring the execution of any aspect of the process. To this end, MIS must be in contact with the actual production system. This can be done either in real time via JMF or through JDF afterwards. JDF also provides completion data for each node that will be passed to the job tracking system by the MIS system. For completed jobs, they will be passed to the job computing system by the MIS system, which will determine the cost of the entire job based on the records in the JDF.
