CIP4 ink preset has unlimited potential in Chinese newspaper industry

The printing process is generally divided into several processes before printing, printing, and printing. Whether it is commercial printing, newspaper printing, or packaging and printing, the above steps are required to obtain the finished product. So, printing is a set of interconnected processes. At present, the continuous introduction of new technologies, especially the large-scale application of CTP technology, automatic printing plate replacement, automatic car wash, automatic register function, MIS enterprise management information system application in printing companies, so that people print information and print management information The delivery and the accuracy of its delivery process put forward higher requirements. With the continuous deepening of digital information reform, the exchange of print data becomes possible.

In order to facilitate the orderly and extensive linking of printing processes, the concept of printing data control was put on the agenda of many printing equipment suppliers, and CIP4 came into being. Its meaning is "prepress, printing, and postpress integrated international cooperation." The organization has developed from the CIP3 base to increase the expansion of functions for corporate management and e-commerce, achieving the full integration of printing processes, and achieving the printing factory's Job process evaluation, acceptance, scheduling, production, production process tracking, delivery arrangements, financial management and other processes of automated management. CIP4 enables digital printing process management to integrate prepress, print, and postpress processing without hindrance. With the continuous further development of digital production, printing processes will surely be more closely linked to each other, which will play a positive role in improving printing production efficiency, product quality, production efficiency, and reducing waste of consumables.

The Role of CIP4 in Newspaper Printing

From the current situation of China's newspaper printing, the digitized production of graphic and text information has entered a mature stage, and the network of information transmission has become increasingly perfect. The resulting digitized flow production and control are increasingly concerned by newspaper printing factory managers. Newspaper printing factory adopts CIP4 technology to bring convenience to work and increase economic efficiency. JDF job ticket is used to define and control the printing process, including layout size, proofing status, output settings, folding and collation information, etc.; with CIP4 The ink preset function in the printer pre-adjusts the ink transfer mechanism of the printing press; through CIP4, it monitors the whole work of the whole job, and even manages the cost and distribution through it.

CIP4 ink preset application in China newspaper industry

The printing market in China's newspaper industry is growing at a rapid rate and the market competition is becoming increasingly fierce. Enlarging the edition, increasing the color layout, and shortening the time for information transmission have become an important means for the newspaper company to develop steadily. The newspaper office is increasingly demanding for printing. In order to meet the requirements of development, newspaper printing companies have invested a lot of manpower and material resources to purchase large-scale high-speed rotary printing equipment, increase CTP systems, and expand production capacity, in order to speed up the production cycle of newspapers and improve newspaper printing quality. The use of CTP technology has shortened the plate making cycle and greatly improved the precision of overprinting; the application of high-speed printing presses has achieved efficient and accurate printing; and the CIP4 ink presetting system has been able to give full play to the advantages of CTP and new printing equipment in terms of speed and quality.

At various stages of newspaper printing, there is a considerable amount of information that needs to be repeatedly input and recalculated. Among them, ink key control is the most obvious. In the constant adjustment of ink, a large amount of paper is consumed, which has a great influence on the production cycle of newspapers. Some companies use a plate scanner to scan the sturdy upper plate, and then transfer the graphic information of the plate to the press console to realize the pre-adjustment of the ink. This method is complicated in operation and large in investment, and it takes a long time due to the generation of ink key control information by a plate scanner, and it is difficult to meet the demand for newspapers with higher timeliness requirements. CIP4 can preset the ink key of the printing machine, and the page is translated when raster processing is performed to ensure high precision, effectively improve the rationality and accuracy of the ink distribution of the printing machine, save the ink transfer time, and reduce the printing waste. Rate, reduce paper waste, improve newspaper printing quality, provide management basis for the balance of quality among multiple units. However, due to various reasons, newspaper printing companies often have the following problems in production:

1. Plate making does not meet the printing specification

2. No proofing or proofing, but proofs do not match the color of the proofs;

3. There is no reference basis for adjustment on the machine, there is no quantitative standard;

4. In the operation control process of the printing press, it is affected by the operator's human factors;

5. The printer's working condition is unstable, and the printing quality is unstable;

6. The different types of printing presses and the different quality of the operators have caused great differences in newspaper printing quality when multiple units are printing simultaneously;

7. The machine adjusts the ink volume many times and affects the production efficiency.

8. The speed of web offset printing presses for newspaper printing is long, the time for ink transfer is long, and the waste of paper and ink at the beginning of printing is very high.

9. Prepress and printing departments are independent of each other in the system, and their printing quality is problematic.

10. No related data can be followed for the overall quality management of the printing plant.

The CIP4 ink preset system not only solves the above problems, but also provides a complete solution for newspaper printing companies.

1. The ink pre-setting system is located between the pre-press printing, based on the layout information, in accordance with the CIP4 standard, and using the ink information as a link to link the pre-press printing process and realize the digital workflow management of the printing factory.

2. The ink information generated by the ink preset system can directly analyze the layout information, and the data is accurate, which truly reflects the ink coverage during the printing process of the printing plate, saves the time for the printing machine to open the printing machine, improves the production efficiency, and reduces the waste of consumables.

3. The ink presetting system considers many factors that affect the printing quality, including the printing quality problems caused by human factors, ink characteristics, paper characteristics, printing machines, etc., and formulate corresponding documents according to the specific working environment.

4. The ink preset system provides a platform for companies to adopt digital production and management processes.

Of course, the survival of CIP4 must have corresponding conditions, and quite a number of newspaper printing factories in China have already used the conditions. The networked and digitalized production mode of these newspaper printing factories has taken shape; digital front-end information collection and processing has matured, and some newspapers have adopted or will soon adopt CTP technology; press configuration has been improved, and domestic newspaper printing companies have introduced printing in recent years. Devices are configured or reserved for the CIP4 interface. The ink preset information works as follows:

1. Electronic layout, generate complete layout information;

2. Large version of the information is RIP rasterized;

3. The rasterized file is transformed by software to generate low-resolution layout information;

4. The layout information is calculated according to the structure of the printing machine and according to the sequence of the printing plate and the different areas, the ink coverage value, namely the CIP4 ink JDF file is calculated;

5. The JDF file is transmitted to the console of the press web press via a network or other storage medium.
6. The console accepts data and automatically controls the corresponding ink key for ink supply.
