It is now generally recognized that for a high-quality book, not only must it have good plate-making technology, exquisite printing effects, but also high-quality binding quality, it can complement its design and content and have a long-term Use and preserve value.
With the increasing demand for the quality and characteristics of printed publications, the situation in the past that only focused on pre-press and printing, and disregarding the binding and finishing process has changed a lot. It is now generally recognized that for a high-quality book, not only must it have good plate-making technology, exquisite printing effect, but also a high-quality binding appearance, it can complement its design and content, and have a long-lasting Use and preserve value. However, due to the wide variety of post-press processed products and complex processes, there are many factors that affect product quality, and quality management is more difficult. The author believes that the implementation of standardized and standardized production is not only the need for product production control, but also a solid foundation for large-scale production. Here, I combine my many years of experience in quality management of post-press processing to make a brief discussion on how to improve the quality of post-press processing.
Strengthen employees' quality awareness
The truly qualified products depend on the joint efforts of all employees. Only all the personnel involved in the production have improved their quality awareness and their own technical level, and they have been produced in strict accordance with the standards. Market competition is invincible. To improve the quality awareness and technical level of employees, it can be achieved through education and training.
1. Let every employee realize the importance of improving product quality, so that the quality policy formulated by the company can be implemented without compromise. To make every employee deeply realize that without quality, there will be no today's job post, and establish the concept of "quality is the post" and a strong sense of ownership among the vast number of employees.
2. Organize employees to carefully study "Quality Standards", "Quality Manual", "Job Responsibilities", etc., so that each employee knows what the quality standards of the products they produce should be, and know what kind of products are high-quality products, qualified products and For unqualified products, employees' income is directly linked to product quality through the "Quality Award and Penalty Measures".
3. Carry out technological education and encourage employees to study technology. Under the organization of the core quality department, technical training is provided to employees, and relevant captains are organized to participate in the preparation of process documents, and certain process parameters are updated and modified as necessary to make them closer to the actual situation and increase their authority. Extensive technical competition among employees among departments, and selection of advanced machine teams and advanced individuals, in order to encourage employees to pay attention to the cultivation and improvement of their technical qualities.
Quality awareness education can also be widely publicized and educated internally through meetings, in-plant briefings, study classes, and the establishment of quality feedback columns. Since the printing enterprise is a service industry, it is necessary to pay attention to customer quality information feedback, organize relevant personnel to discuss the problem in time, and propose corresponding solutions and measures. The weekly regular meeting insists on carrying out quality publicity and quality summary in order to strengthen the vertical communication of quality issues.
Quality awareness education is a long-term and arduous quality management task. Only when the quality consciousness is firmly rooted in the thoughts of each employee will there be a qualitative leap in quality. Maximizing the enthusiasm of all employees to grasp product quality and maximizing the production technology level of each employee is the ultimate goal of quality awareness education.
Strengthen process control and formulate processing plan
As a production manager of a printing enterprise, only by being familiar with the products to be processed and the existing equipment status and technical strength of the factory can we formulate a reasonable processing plan and produce good products.
1. After receiving the construction order and cleaning samples, the production management personnel must first understand the process requirements and the quality of the materials used, make a review of the wool samples and the construction order and cleaning samples, and confirm whether the established requirements of the construction order can be met during processing.
2. According to the existing equipment status and technical strength of the workshop, formulate a detailed processing plan, including processing sequence, process methods, materials, equipment and quality standards, and indicate the quality points that the product should pay attention to in each process to improve the machine The strength and effect of the Taiwanese personnel ’s self-examination, in order to better prevent the occurrence of quality accidents, stabilize and improve product quality.
3. Establish product technology and quality files. With the development of technology and market, post-press processing is also facing more and more new processes and new problems. Enterprise employees must not only be familiar with the performance of the equipment but also understand the requirements of the new process, but also make a record of various situations that occur during the processing of products with different processes and different materials, and retain them for sample storage and establish product process files. . Through the induction, sorting and summary of the process files, it provides reliable guidance for production. Carefully record the quality problems and their solutions found in the inspection, establish product quality files, find bottlenecks that affect product quality, and address them in a targeted manner to effectively avoid the same mistakes from recurring. As the first-hand information of production, product process and quality files can avoid detours in the future and realize a virtuous cycle of product quality.
Scientific scheduling and balanced production
On the surface, the commissioning work is to ensure that the production is carried out normally and the tasks are completed normally, and it seems that it has little to do with quality. In fact, otherwise, reasonable and scientific scheduling can largely guarantee the quality of products. Especially in the current situation of "short cycle and high quality", the restraint between product cycle and quality can only be solved by reasonable and scientific production scheduling arrangements.
1. For the products of the same variety, it is generally printed first and then printed later, giving the printed product a relatively long drying time to allow it to dry naturally and avoid the large amount of ink causing the printed product to become dirty; After cutting, the paper continues to expand and contract, resulting in uneven cuts, dry ink, and blistering.
2. For different products that are due at the same time, the processing and production sequence should be arranged according to the complexity of the process. For example, hardcover products and saddle stitched products that are due at the same time, you should arrange the folding of the hardcover products as much as possible to ensure that the book block has a longer binding time to allow the book case to dry naturally, so as to ensure the finalization of the finished book The shell is not warped.
3. When the production of the upper and lower processes are closely connected, scientific production scheduling can effectively avoid the phenomenon of waiting for work and rushing due to errors in production arrangements, which not only improves the efficiency, but also avoids the phenomenon of "the carrot is not washing the mud".
The improvement of post-press processing quality is of course inseparable from pre-press and printing processes. If pre-press design and printing can communicate more with post-press processes, I believe that product quality will be further improved.
