Newspaper printing has developed extremely rapidly in recent years. With the application of digital workflow and CTP technology, the pre-press digitization has gradually been realized, which has brought another technological revolution in the printing field. On the other hand, the amount of newspaper information is expanding, the color layout is increasing, and the information transmission time is shortening. In order to improve the market competitiveness of newspapers, some new technologies and new products have attracted the attention of the newspaper printing industry that pursues timeliness, which can be used to improve The printing color control technology of printing effectiveness and stability of newspaper printing, printing ink control technology, is a successful application. · The main problems of current newspaper printing When newspapers are printed, the operators of the printing press often do not see the manuscript, and can only adjust the ink volume of the printing press with the experience of the collar machine, which often causes the printing ink color to be inaccurate; on the other hand, due to the difference in personnel quality, the printing press Factors such as hardware differences have caused the increase in printing adjustment costs and unstable printing quality. Enterprises that use digital proofing will be better. Experienced leaders can analyze the color characteristics of the layout based on proofing proofs and adjust the ink keys of the printing press in advance, but they still cannot significantly improve the efficiency of printing production. In addition, the adjustment of the ink key is time-consuming and labor-intensive. It usually needs to be debugged several times to meet the requirements. The speed of the rotary printing machine is quite high, and a large amount of waste will be generated during the ink color adjustment process, and precious time will be wasted. Some printing factories also used the printing plate scanning method in the early days to transfer the color separation information generated by hardware scanning of the printing plate to the printing press console to complete the ink key presetting. However, this method is complicated to operate, wastes time, and requires a lot of investment, so it is not suitable for a high-efficiency production enterprise such as newspaper printing. The ink control technology introduced by Gaoshu is an effective solution to the problems faced by the newspaper industry, such as how to shorten the printing cycle, improve printing quality, and reduce production waste. · Ink control technology introduction The main body of the ink control technology is a CIP3 ink control software that can preset the ink keys of the printing press. It directly reads the graphic data after RIP, and analyzes the machine control information according to the size of the printing plate and the number of ink keys It is recorded in the PPF file or printed on paper, and then used for the ink key preset of the printing press, which ensures higher accuracy and greatly improves the rationality and accuracy of the ink area allocation of the printing press. Using this efficient information transfer mode can standardize the operation of staff, save printing preparation time, reduce waste of consumables, and improve newspaper printing quality. It changes the traditional way of pre-adjusting the ink color of newspapers based on the working experience by the press leader. Ink control technology provides guarantee for enterprises to adopt digital production and management processes. Regardless of whether the printing press has a CIP3 information interface, you can enjoy the results of the ink control technology. · Ink control technology implementation application process First, the software receives 1-bit TIFF files after digital imposition, and has the following two functions according to whether the printing machine has a CIP3 / CIP4 information interface. (1) Print the ink volume information through the windows printer. The direct use of CIP3 ink volume data requires a corresponding environment, especially the printing equipment needs to be equipped with CIP3 / CIP4 information interface. For printers that do not have this interface, it was impossible to enjoy the benefits of CIP3 digitization before. With ink control technology, the leader can adjust the ink key according to the printed standard information, which is faster than manual analysis or plate scanner to obtain information, thus shortening the pre-press adjustment time, making the CIP3 / CIP4 information interface Printing presses can also enjoy time-saving and efficient digital advantages. (2) Generate PPF file For the printing machine with CIP3 / CIP4 ink information interface, the system can convert the layout color information after RIP into standard PPF data, and transmit the data to the corresponding printing machine control system to realize digitalization. Automatically adjust the amount of ink. ·success case Some newspaper printing companies, such as Hangzhou Daily Newspaper Group and Changsha Evening Newspaper Group, have achieved remarkable results after adopting the ink control technology introduced by Gaoshu. (1) The production efficiency is significantly improved, and the printing preparation time is shortened by 5 to 8 minutes. Due to the accurate ink area analysis data entered in advance, the color of the first newspaper printed after startup can basically meet the requirements, and then adjusted slightly It can be officially printed at high speed. (2) The printing quality is improved, especially the color newspaper printing. Because the control data of each machine is unified, the color is stable, so that the printing quality no longer fluctuates, and the amount of newsprint is also reduced. (3) Established a set of digital and standardized printing production process for the newspaper office printing plant, making the technical training of new employees available, and changing the printing control from empirical to digital control to a comprehensive printing digital process The continuity is one step further.
