The quality of printed products is not only a concrete manifestation of the quality of corporate management, but also a concentrated reflection of the overall quality of the enterprise. Only by striving to improve the quality of printed products can we meet the requirements of continuous development and market competition, and enhance the viability of enterprises. Therefore, no matter what kind of environment, strengthening print quality management has become an eternal theme of corporate management. So, how to fundamentally improve the quality of printed products? The author believes that it is necessary to strengthen the quality source control, and to prevent the occurrence of various quality problems, we should focus on the following aspects.
Improve the corporate management system
Printing companies have both labor-intensive production characteristics and technology-intensive process characteristics, and management is particularly important. This requires the use of institutions to organize, standardize, direct and direct production. On the basis of implementing national standards and industry standards, enterprises should also formulate a complete set of quality management systems and measures according to the actual situation of the unit, from raw materials to semi-finished products, from plate making to printing, from printing to post-press processing. The process carries out the quality inspection and control of the whole process, which process has the quality problem, and the economic responsibility of the process owner is investigated, and the high sense of responsibility and self-consciousness of quality self-test and self-control are formed. In addition, those who are excellent in quality should be given certain economic rewards, and the quality and personal economic benefits should be linked. In this way, the system will be rewarded and punished, so that the quality management of the enterprise will be in a virtuous cycle. Therefore, for the printing enterprises, the establishment of quality proofing system, sampling inspection system, mutual inspection system, various procedures and rewards and punishments system is undoubtedly a better management measure for quality source control.
Strengthen staff technical training
Technical training for employees in printing production enterprises is an important measure to improve product quality. Through systematic technical training for employees, employees can improve the quality of printing technology and improve the level of operation technology and technology. This is also an important guarantee for improving product quality. The content of technical training for employees should include production process technology, practical operation technology knowledge, production safety, quality control and printing standards. Through training, the production technology level of employees will be greatly improved, and the production quality will be reduced and the product quality will be improved. The basics. The technical quality of the employees has been improved, and orderly production can be carried out according to the quality standards and production process rules, in order to effectively reduce or avoid the occurrence of various quality problems.
Choose a qualified supplier
The procurement control of raw materials of printing enterprises is to make the product quality and production efficiency have a good balance on the most economical basis. This requires enterprises to choose manufacturers with a certain scale of production, because of the production of large-scale production plants. The capabilities, process technology, product quality and production cost control are relatively good, and the product quality is relatively stable. Choosing such a supplier is conducive to improving the quality of printed products and reducing production costs. Suppliers with stable and reliable quality must be carefully evaluated by the supplier's qualifications to ensure the stable supply quality of raw materials. The evaluation of suppliers is mainly based on the trial and actual use effects of raw materials in the production of the company, such as the economics, adaptability and stability of the materials used. Suppliers who often fluctuate in the quality of raw materials and affect the normal production and quality of enterprises must be eliminated, so that effective control can be carried out from the source of quality to ensure the stability of printed products.
Develop prepress process
The production practice of the printing enterprises in Qufu City clearly shows that the pre-press process measures and procedures are well implemented, and there are fewer opportunities for printing quality problems. Therefore, it is very important to formulate a strict process before printing. According to the structural characteristics of the product, the technology of the imposition process should be closed. It is necessary to select the equipment model and the ink brand according to the characteristics of the printing, and arrange the printing color sequence scientifically. . In addition, the completed film and printing plates should be carefully checked for proof, and quality hazards should be dealt with in a timely manner to prevent quality problems.
Put the quality of raw materials off
Raw materials are the basic link of quality control in printing enterprises. Only when the quality of raw materials is good, the quality of printing can be reliably guaranteed. It is necessary to scientifically and reasonably use and manage printed raw materials to prevent quality problems.
First, according to the characteristics of the printing, select the appropriate ink type for printing, to avoid the occurrence of printing quality problems due to blindness in use, such as packaging products to prevent the occurrence of color quality problems, should choose the light fast, wear characteristics Ink. At the same time, it is necessary to pay attention to the amount of ink in stock to prevent deterioration of the backlog and affect the printing quality.
The second is to strengthen the quality control of the plate material. Because of the different quality and use effect of the plate brand, there are obvious differences in the quality of the surface layer of the PS plate. If the quality of the surface layer of the PS plate is unstable, the poor performance of the grease is so low that the printing durability is low. The emergence of dirty and other problems not only affects the quality of the product, but also reduces the production efficiency. Therefore, for the poor quality of the plate, the price can not be used.
The third is to strengthen the quality control of printed paper, scientifically and reasonably master the paper inventory time and storage conditions. In general, printing paper is put into use half a year after production, and the printing quality is relatively stable, which can reduce the chance of printing deformation, wrinkles and static electricity, and is beneficial to improve the accuracy of product overprinting. However, if the paper has accumulated overstocking time for too long, if it is more than two years, it will be prone to discoloration and brittleness. Therefore, the inventory should be reasonably maintained according to the actual production situation, and the principle of advanced use should be mastered in use. At the same time, it is necessary to scientifically store the paper, and to prevent heat, sun, anti-folding, anti-pressure and moisture-proof. The paper should be kept between 20cm and 30cm away from the ground and not less than 40cm away from the wall. The temperature can be controlled between 18 ° C and 22 ° C and the relative humidity is maintained between 60% and 70%. Make the paper quality relatively stable.
The fourth is to strengthen the quality tracking and inspection of raw materials. In the daily work, the Quality Inspection Department should conduct comprehensive quality tracking management on the use of raw materials such as ink, plate and paper, and find out the problems in a timely manner to avoid the hidden dangers caused by blind purchases. Good printing quality source.
Maintenance production equipment
As one of the production factors, printing equipment largely determines the printing quality of products. High-precision equipment is the basis for printing high-quality products. Therefore, it is necessary to carefully take care of the equipment and clean the equipment. For the roller shaft head, bearing bush, gear and the key parts of the front gauge and side gauge work, it is necessary to maintain a good lubrication state to prevent the use of wear and affect the printing quality. This is an important measure for printing quality control. In addition, daily attention should be paid to checking the operation of the equipment and finding problems can be dealt with in a timely manner.
In short, the management process of corporate printing quality is essentially the process of controlling and controlling all aspects of prepress, and only through the careful implementation of pre-press preventive measures can we prevent the occurrence of various quality problems to the maximum extent, because after all, enterprises The quality of the product is produced in a specific environment. Therefore, only by effectively strengthening the quality source control, the printing production enterprise can effectively prevent various quality problems and accidents, thereby further improving the management level of the printing production enterprises.
