Analysis of Ink Control System in Newspaper Printing

Newspaper printing has developed extremely rapidly in recent years. With the digitized workflow and the application of CTP technology, digital printing has been gradually realized, and another technical revolution has taken place in the printing field. On the other hand, the volume of newspapers is expanding, the color layout is increasing, and the time for information transmission is shortening. To improve the market competitiveness of newspapers, some new technologies and new products are concerned about the time-efficient newspaper printing industry, which can be used to improve The printing color control technology of newspaper printing effectiveness and stability, printing ink control technology, is a successful application.

·The main problems in current newspaper printing

When newspapers are printed, the operator of the printing press often fails to see the originals, and can only adjust the ink volume of the printing press by virtue of the experience of the leader. This often causes the printing ink to be inaccurate; on the other hand, due to differences in the quality of personnel, the printing presses Factors such as hardware differences between the printing presses increased the cost and the quality of the print was unstable. Companies adopting digital proofing will be better, and experienced leaders can analyze the color features of the layout according to the sample proofs and adjust the ink keys of the printing machine in advance. However, the printing production efficiency cannot be significantly improved. Moreover, the adjustment of ink keys is time-consuming and laborious. Usually, debugging is required several times to meet the requirements. However, the speed of the rotary printing press is quite high, and a large amount of waste reports will be generated during the ink adjustment process, which will waste precious time. Some printers also used the printing plate scanning method in the early stage to transmit the color separation information generated by the printing plate through the hardware scan to the printer console to complete the presetting of the ink key. However, this method is complicated to operate, wastes time, and has large investment, so it is not suitable for high-efficiency production enterprises such as newspaper printing.

Gao Shu's ink control technology is an effective solution to the problems faced by the newspaper industry, such as how to shorten the printing cycle, improve the printing quality, and reduce production waste.

·Introduction to ink control technology

The main body of the ink control technology is a CIP3 ink control software that can preset the ink keys of the printing machine. It directly reads the text data after RIP and analyzes the machine control information according to the plate size and the number of ink keys. Recording or printing on paper in the PPF file and then using the ink key presets of the printing press ensures higher accuracy and greatly improves the rationality and accuracy of ink distribution in the printing press. Using this efficient information transfer mode, it can regulate the operation of the staff, save printing preparation time, reduce waste of consumables, and improve newspaper printing quality. Changed the traditional way of working with the printing press to adjust the ink color of newspapers according to work experience. Ink control technology provides protection for companies adopting digital production and management processes. The result of ink control technology can be enjoyed regardless of whether the printer has a CIP3 information interface.

·Ink control technology implementation application process

First of all, the software receives the digitally imposed 1-bit TIFF file. According to whether the printer has a CIP3/CIP4 information interface, it has the following two functions.

(1) Print ink volume information Prints ink volume information through a windows printer. Since the direct use of CIP3 ink volume data requires a corresponding environment, especially for printing equipment that requires the configuration of CIP3/CIP4 information interfaces, it is impossible for a printing machine that does not have such an interface to enjoy the benefits of CIP3 digitization. With the ink control technology, the collar can adjust the ink key according to the standard information of the printing, so that the information can be obtained faster than the manual analysis or the plate scanner, thereby shortening the pre-press adjustment time, so that there is no CIP3/CIP4 information interface. Printing presses can also enjoy time-saving, efficient digital advantages.

(2) Produce PPF file For the printer with CIP3/CIP4 ink information interface, the system can convert the RIP post layout color information into standard PPF data, and transmit the data to the corresponding printer control system to achieve digitalization. Automatically adjust the ink volume.

·success case

Some newspaper printing houses, such as Hangzhou Daily Newspaper Group and Changsha Evening News Group, have achieved remarkable results after adopting the ink control technology introduced by Gaoshu.

(1) The production efficiency has been significantly improved, and the preparation time for printing has been shortened by 5 to 8 minutes. Due to the accurate ink area analysis data input in advance, the color of the first newspaper printed after start-up can basically meet the requirements, and then slightly adjusted. It can be officially printed at high speed.

(2) Improved print quality, especially for color newspaper printing. Because the control data of each machine unit is uniform and the color is stable, the printing quality no longer fluctuates, and the amount of newsprint is also reduced.

(3) Established a set of digitalized and standardized printing production process for newspaper printing factories, which allowed new employees to have technical training based on evidence, enabling printing control to change from experience-based to digital-controlled, to a comprehensive digital printing process. Going further and further.
