Standard specification throughout the printing process
What is CIP, neither hardware nor software, but a group that sets standards and regulations for printing production and management. CIP stands for Computer Integration for Printing, including the world's famous prepress equipment, printing presses, and postpresses. Processing and printing graphic software company to digital printing company, they are seen in the computer age, printing machine manufacturers, prepress equipment, especially CEPS high-end computer group page system, prepress typesetting, editing system, to Post-processing control system, often everyone develops their own computer-controlled hardware and software, and also defines their own work specifications and processes, and uses computer programs and languages that they think are appropriate. If this is infinitely developed, not only pre-printed design editing files, And the plate negatives and plate output, in the future, only the same brand can be compatible, and other brands are like chicken and duck, and then from the prepress and printing to the post-processing, using different computer languages, programs and Control logic, as well as work content and device definition, are more than old and can't interact with each other. Even if it is the same prepress equipment, but different brands have to take out the machine, they have to listen to different languages, just like the Macintosh and PC computer more than ten years ago, the two programs can not be mutually common, so the printed page file is converted. There is no chance. This situation is even more terrible in the printing machine room. If there are 6 machines, it is divided into four brands, and the plate supply source, in addition to the home plate, there are three other plates in the supply, if the traditional If the plate scanner scans the plate, it may be necessary to use two or three stencils to scan the print distribution information file and then convert it into the order of the ink distribution of each ink key, because Heidelberg has its own plate scanner. Roland also has its own, Japan's Demia sweeping machine, although the various brands have formats, but not quite correct (the scanning accuracy is only 65% accuracy) and the investment is huge, for different label printing machines, naturally This is suitable for the format language prints that the respective presses can receive in order to function. If you do not need to scan the plate, then when there is no consistent file format to standardize, different CTF film output machines and different CTP plate output machines, after the RIP is finished, the print distribution file should output the appropriate information format for different brands. This will be very troublesome when the press is in use. Therefore, a certain Japanese machine printing is arranged in advance, and the result is that the work must be transferred to the German machine. For example, the memory format of the previous tape and magnetic card cannot communicate. So Adobe, Kodak, Agfa, Fujifilm, Heidelberg, Roland, Komori, Mitsubishi and other more than 10 factories, to organize the organization of CIP 3 (Computer Integration for Prepress Printing Press Postpress), that is, to print through prepress, printing Work and post-processing, develop work orders for instructions, specifications or specifications that everyone can use, so you can not only cross-platform, cross-software, but also the types, definitions and order of materials and operations in the process. If the printing machine changes in paper, it must be made of Feida size, Feida head, wheel paper table, double sheet inspection, side gauge, front gear, printing pressure, paper conveying air kit, glazing. Unit, delivery table size, vacuum brake, upper fan and dusting, etc., there may be more to change, such as air nozzle, suction air volume or roller table position, vacuum belt, vacuum side The change in the suction volume of the gauge, etc., is a mechanical size change, there may be hundreds of places, and remote digital adjustment must be done. An eight-color machine has a change in the total ink supply volume of nearly 250 ink keys and eight ink-slot rollers. These parameters are not only pre-set before printing, but also in school calibration and school color. To make the change adjustment, when it is officially printed, it is more likely to use the wired or offline concentration scan measurement to compare the printed data with the data of the OK Sheets, and then change the ink key opening of the difference value. Adjustment, even the change in the total amount of ink should be adjusted, such equipment, if there is no CIP unified specification interface, the control will be different due to the different brands, and different information programs and format changes should be made. CIP organization, under the same definition and regulation of different brand equipment, the difference is not big, and the use of PDF files in the format of ClP 3 is naturally easy to communicate. The emergence of the CIP 3 organization is valued by many hardware device manufacturers, software development companies, and even companies such as Adobe. This is not just a unified command, program, and order, plus a program specification language. More important is the things that have been done before and the information already known in the printing project. Don't re-enter the next project. Such as customer name, phone number, address, contact person, job name, specification, color, plate making, prepress service, paper type, size, thickness, binding processing, quantity, special needs and ordering, etc., as in the back end Re-entry sometimes makes mistakes, and it takes time to deal with it. CIP 3 should be said to be able to be standardized to the back-end processing, but it has been used by many people for many years. For the folding machine, riding and binding machines, Horizon More active cooperation.
The core value of CIP 3 is to convert it into a 2400, 2540dpi dot matrix file for the output of the output machine. This kind of electronic negative film, if used in the ink key distribution area of various printing machines, is divided into regions by the mouth to the end of the screen, and then accumulates the percentage of the print distribution in each area, and prints the ink supply areas of each color version. The distribution information is provided to experienced or inexperienced printer operators for pre-setting reference of ink key opening. This is the most important accurate reference data. If there are different curves, it is necessary to select appropriate paper and ink. The curve of the printing condition is used for parameter conversion, and the direct and precise operation of each color plate and each ink key opening degree is directly performed. This information generated by the pre-press, to the operator of the printing machine, do not have to look at the printing plate to do the adjustment of each ink key area in response to the print distribution information on the CIP3/CIP4 printing plate (generally the original output file transfer 72dpi The use of the left and right file is not only the core value of CIP 3 information, but also the important application value in the new system of CIP4.
CIP4 makes management analysis perfect
In fact, CIP3, which was developed in 1993 and has three processes of pre-press, printing process and post-press processing, only processes from the front to the downstream, transmitting known information files for application. But soon Heidelberg, Manroland, Agfa and Adobe are also working on a more complete print management tracking system, and even can collect a lot of production information for the next reprint or similar work, and can be used JMF files, automatically log a lot of work materials and setting information to the MIS asset management system, and then analyze and compare them later, such as cost, profit margin, work efficiency, equipment and personnel efficiency, to further deepen management. And provide printing companies and customers in the printing of the trace, giving great convenience. The collection of these information can be tracked and reused, as well as the “processing” of the analysis. The CIP3 only attaches importance to the information flow of the work. CIP4 adds many more complete information collection, tracking, analysis, and even special instructions on the instructions. For example, the printing Lab value of the ink color, the number of instructions in different editions in the printing, etc., the CIP4 sponsoring members are overlapped in the CIP3 framework, so the official establishment in 2000, by Prepress, Printing-Press, Postpress, etc. 3P, plus The fourth P on Data Processing data processing became the new organization of CIP 4. The CIP4 organization basically provided specifications and consultation, and was not a software or hardware producer itself. CIP 4 changed the work order and work order. In the JDF file mode, the workpiece customer, name specifications, requirements and special requirements, precautions, even Lab color value concentration requirements and various post-processing parameters are also written. If the print distribution file is completed, it can also be stored together. JDF (Job Definition Format) work identification file, a set of CIP 3 data, more standardized definition and use, many files in one It is also easier to identify and use. The JDF file is changed to XML extensibility language. It is more capable of loading many new work instructions and regulations than the PDF language used by CIP3, and the XML file is also one of the same cross-platform easy-to-use languages. .
CIP4's JMF (JOb Managment Format) work management information file, providing working production parameters, and automatic communication, connection and login mechanism to the MIS asset management system, so the operator's work tracking does not have to be distracted to do the keyboard and The input of the screen data affects the operation according to the response. The JMF file is operated by each device, and the user actively logs in to the asset management MIS system, so where the work goes and when it is expected to be completed, regardless of the work department, the factory and the supervisor Even the allowed customers can access the computer system to check the progress of the workpiece in production and the expected completion time. Moreover, the reprinted workpieces can all be adjusted or set parameters in the previous production, and the production is performed under very similar conditions. As long as the CIP 3 is recorded by the tape and magnetic card recorded on the console of the printing machine, the others are rarely repeated. Use previous production information. Some non-reprinted prints can be found in the case of CIP4, and the same production parameters can be found. For example, 80P snow paper can be used for the next issue of magazines by printing the information files of 888-640mm books, as long as the print distribution is replaced. The file can be used, even the same size of the print, it can also be used to do the printer size, thickness, air volume and dozens of production parameters of the whole machine to quickly and accurately adjust, just replace the print file of the content can be, as for The back origami, binding, and cutting parameters are also of great value, thus saving a lot of production time. However, the premise is not only the dimensional change, the change of the printing pressure, but also the digital servo control device is possible to do the numerical control centralized memory and centralized digital adjustment. In addition, the air volume and other such as the ink roller timing, swing adjustment, also have to do the numerical control adjustment facilities, the same as the ink slot button if the manual adjustment with the screw, there is no possibility to do the remote button to adjust the ink control, but can not refer to The digital control of the memory card or CIP 3/CIP 4, so the premise of full CNC, the servo-power digital control of the device control is indispensable.
On the MIS asset management system, the production process and production parameters have been registered. In addition to production and reuse, there is a greater use in the future, which can be used as a cost analysis, the cost of an artifact at the valuation and the actual cost at the time of production. Do analogy, as the basis for analysis and improvement, the price is too high, too low or the production can not meet the original standards, even if the materials are not suitable, it should be frequently shut down for cleaning and wiping, or the fly can not be slow. Production and so on, then the use of such materials in the future should be included in the unpopular, or increase in price to accept production. In the production of machinery and equipment due to lack of maintenance and old production is not smooth, you can also get information from MIS printing speed, production downtime, in order to improve. The analogy of the personnel, the operational advantage of that one can be used for learning transfer. In addition to the case analysis, the production review and inspection of the whole season and the whole year are more important. With the information of MIS, how to find the right person, to find the right person, and to work in a proper and efficient way is another material that can be used. The ER management information is beyond the ERP system as the backbone, from the previous valuation system, work print establishment, to workflow management, production aging evaluation and production machine alignment, raw material order supply, production specification transmission to the completion of the workpiece The quality assessment, cost assessment and accounting establishment, plus the structure of the financial system and management system, in today's information age, more and more production information and management information combined with accounting and financial information is a Very valuable thing. There is only a system that only makes the road well, no vehicles use it for circulation, and no matter how good the road is. The ERP asset management system after MIS is different from each manufacturer, so it will take a long time to establish. Unlike the CIP 3/CIP 4 system, there is a consensus on definition and production logic. There are no different brands and Different gaps in operational use exist.
