1. Responsible for the publicity and education of “quality is life” for the whole factory staff, supervising and inspecting quality standards, conducting product quality checks, establishing and improving various assessment, statistics and analysis work.
2. Strictly implement the system of “self-inspection, mutual inspection and special inspection” to deal with the quality problems that arise during the production process. The defective products must be registered and signed by the quality inspector before they can be out of the workshop to prevent the waste from flowing into the next process. The workshop will find out the reasons, take improvement measures, and do an analysis of the accident registration processing.
3. Regularly analyze and study, solve the quality problems of each process, and do a good job in implementing the work.
4. Organize various quality competitions, evaluate work, and summarize relevant quality data and materials.
5. Responsible for the review before printing and before binding, check the “standard sample” of offset printing and printing, and check the quality of the finished product.
6. Responsible for the management and inspection of the process regulations.
The importance of the signing system in quality management
The signing system is the most common quality control method in printing enterprises. The quality of a proof sheet is directly related to the quality of the whole batch of products. The quality of products directly affects the efficiency and reputation of enterprises. The qualified sample proofs undoubtedly become the quality standard of the batch of products, and become the "reference" for the self-inspection of the machine personnel. Sanya Zhicheng Color Printing Co., Ltd. strictly implements the ISO9002 quality assurance system, paying special attention to strictly implementing the signing system before starting each process, setting up a screen to prevent some unnecessary quality accidents, and the overall product quality of the company. The improvement has played a decisive role. Our main experience is as follows:
First, the company has developed a product classification system and a sample system for various products.
In order to effectively carry out production and inspection, we classify the company's products into three categories: Y grade (excellent grade), grade H (qualified grade), and grade P (common grade) (H grade and P grade are listed as General product).
Y grade: small boxes, middle boxes, cartons, color samples, color leaflets, hand-made bags, color bottle stickers, etc. of each pharmaceutical factory. Such products are the company's key products, requiring three levels of sample, the workshop director is the first level, the quality inspection department manager is the second level, and the general manager is the third level.
Class H: The instructions of each pharmaceutical factory and the four-color printing in the social printing are all such. The second-level signing is performed, the workshop director is the first level, and the quality inspection department manager is the second level.
Class P: Offset paper or coated paper in social printing is of this type. It requires a first-level signature and the quality inspection department signs the sample.
The operation department and the production department respectively indicate on the construction order form and the production work order by these methods to guide the production and inspection of each process. In the process of executing the signing system, the company not only sent the proofing products to the customers for the first batch of products printed for the first time, but also invited the customers to go to the workshop to confirm the samples and prevent unnecessary disputes.
Second, the offset printing workshop is the leader of the enterprise, and should be well signed.
The following should be noted when signing the sample in the workshop:
a. The paper type, specification and ink type used are consistent with the production work order.
b. Whether the rule line is complete and the overprint is accurate.
c. Whether the amount of ink is even and flat. If it is a network cable version, whether the dot is lost or blurred, and the angle of the cable is correct.
d. Whether the hue is consistent with the sample, the newly adjusted spot color ink must be sent to the QC department for confirmation before use.
e. Whether the position of the pattern is correct, whether it is in the paper, whether the text is correct, whether there is any missing version, missing words, typos, and lack of pen break.
f. Measure the density of the sample proofs in time and record, and write the proportion of the color sequence and the spot color ink.
g. Each batch of product revision should be carefully compared with the sample to check whether the position and pattern are correct. The new version of the product must use the imposition map to check whether the imposition is correct.
h. Self-reversed products should see if the reverse side is scratched, and whether the bite is reversed.
I. Products with die-cutting indentation should be folded on the page, the page number is correct, and so on.
The sample is signed in duplicate, and each of the quality inspection department and the production department keeps one copy and puts them into a special signature storage cabinet. The production department signs the sample as the sample of the next batch of printing, and the quality inspection department keeps the archive.
Third, the significance of the implementation of the signing system
The way of signing is different for each manufacturer. Some manufacturers are in the printing process, after the ink is flattened, two samples are taken from the sample to be sampled. We believe that this method is not serious. The quality of the product before the sample is difficult to guarantee. If it is negligent, it will result in batches. Product scrapped. We use the first sample, after printing, try to use more paper, after the ink is flat, the content has reached the company's best results before signing. Although this takes a long time, the quality can be guaranteed, and the products printed after the sample are basically genuine. At the same time, the printed copy of this batch can be used as the standard for the next printing without revision, and the next printing can be traced. If it is a mid-way sign, the color hue will be farther and farther away. What's more, the printing of the drug packaging, the life of the people, must not give the counterfeiters a chance. However, due to the quality and carelessness of the signing personnel, some mistakes will also be caused. For example, when our company prints a four-color folding business card of a company's CEO, because the signing personnel's blind pursuit of color is consistent, forget to cut the small sample and fold it. After signing the sample, it was discovered that the bite was reversed and the business card was scrapped. Therefore, the signing work is a very serious, serious and careful work, requiring the quality of the signing personnel to be high, and the foundation is solid, so as to prevent problems before they happen.
Only by strictly implementing this kind of signing method can we ensure the consistent color quality of customers before and after, and improve the visibility and competitiveness of the company.
The importance of quality inspectors in printing enterprises
1. To avoid the misuse of the management system
Each printing company's management system will have strict and clear quality policies, standards and other quality management provisions, and will be implemented as a standard for daily work to the quality inspection department, granting quality management a vote veto. However, the reality is that quality control can be artificially relaxed when there are more production tasks, urgent items, and urgently rushed to work. This is a common phenomenon when printing large quantities of books and magazines; When economic benefits conflict, conflicts will often be considered first. Under the suggestion of some kind of enterprise leadership or some form of interference, construction or ex-factory can still be continued. The quality inspection department often feels pressure to double the quality standards. Over time, the quality inspectors have also learned to observe the opinions of leaders at all levels, and the corresponding quality standards have gradually become double or multiple artificial standards, which have no harm to the future development of the enterprise.
2. Unacceptable nanny type quality management mode
In small and medium-sized printing enterprises, the quality of employees is generally not as good as the standard large enterprises. The rules and regulations are not very comprehensive, so it is easy to cause a misunderstanding. The monitoring of product quality relies on the technicians and inspectors. Not relying on all employees to work together. It is believed that a special quality inspector will be assigned to the high-quality products in each process and machine group. As long as a quality inspector is present, the quality problem can be solved and everything is safe. Printing is a systematic project. There are many production processes. The main processes of prepress, printing and postpress processing add up to more than 30. When you are busy, you have to turn the three shifts. If you use the "special person" method, how many quality should be matched? Inspector? This is unrealistic. This kind of nanny-style management also stimulates the dependence of the machine personnel, lazy inertia, does not seek advancement, does not use the brain to actively deal with various technical problems, and sometimes finds some excuses for shirking responsibility: "Quality inspectors have seen After that, it has nothing to do with me." "I won't, I have a problem to find a quality inspector to solve" and so on. With such a working atmosphere, one day the quality inspectors can't be dealt with in time, and the production of the process may be paused. It is really sad.
We should have a clear concept of quality management: quality is produced by the joint efforts of all employees, rather than relying on quality inspectors to monitor each item one by one. In the production process, the technical level, proficiency and responsibility of the first-line operators at the grassroots level are the key factors for stabilizing and improving product quality. The quality inspectors timely and effectively inspect and supervise, and promptly put forward some reasonable suggestions and measures. Make sure the quality is truly monitored. Quality control should be based on prior prevention, that is, process control, followed by data specification operation of each process, combined with self-inspection and mutual inspection of the upper and lower processes and sampling inspection by independent quality inspection department, so that the printing quality can be controlled Within the foreseeable range.
3. The quality inspector's job is not to "walk around"
Many grassroots operators and general managers unilaterally believe that the work of quality inspectors is very easy and is a good job worthy of yearning. The daily work of the quality inspector is nothing more than wide-eyed eyes, holding measuring tools in hand, walking around here in various production departments, strolling there, and swaying for a day.
On the surface, the quality inspector's work depends on the "eyes", but this "eyes" contains a lot of wisdom and skills necessary for quality inspection positions. First of all, it is necessary to have a high degree of relevant culture and technical literacy to be able to perform the quality inspection and signing of various daily printed products. Secondly, familiar with the printing process, understand the operation procedures of each process, and clarify the main causes of common quality accidents. Correction and rectification measures; in addition, dealing with sudden quality accidents is calm and decisive, dare to take responsibility and assume responsibility, and it is convincing to judge the quality accidents without ignoring the water; finally, it is also an important aspect, to be good at making good relations with people. Dealing with the operation and management personnel, we must also pay attention to the principles in the work, but also pay attention to the working methods and methods, so that others feel that the quality inspectors are helping to solve the problem, it is to send charcoal in the snow, instead of looking for people’s blacks all day long. Face judge. The quality inspectors have the ability to respond to the supervision and inspection of the quality of the printed products of the frontline personnel. When they encounter "difficulty", they can communicate with colleagues and leaders in a timely manner.
Quality control mainly starts from two aspects: one is the dataization and standardization of each process; the other is the process management and workflow management and management. The former is the implementation of operational specifications, focusing on actual data, not just listening to reports. Look at the report, you must see it. The latter is based on the data of each process, monitoring whether the workflow and the operational requirements of each process are offset and timely corrected and prevented. This requires quality inspectors to go to the production department to go around and go around in a timely manner to control and eliminate quality defects in time.
4. Quality inspection work should focus on the source of the focus
The quality inspection work should focus on the key points and grasp the source, so that the quality can be effectively controlled. This is the process control requirement. The author believes that the quality control of the entire printing process is mainly in two aspects: one is the check before the pre-press (CTP version), the more complete production process guide and complete inspection means; the second is the post-press processing products. The intensity of sampling before leaving the factory. Of course, the prerequisite for achieving key control is that each process is operated as required. If each process is only in accordance with its own ideas and is free to operate for its own convenience, it is impossible to achieve pre-control. For example, the signatures produced by the rotary printing press are not in accordance with the requirements of the whole book. The size of the folded edges of the signatures is different, the length is different, and the more terrible is that the flat pressing and bundling are not performed in time, so that the signatures are deformed and curled. . When it comes to the post-press binding production, the signatures can't be smoothly matched from the collating machine. The frequent stoppage adjustment of the signatures will result in the linkage production line not being able to produce at a constant speed. In the quality inspection work, it is necessary to be good at summing up the lessons and lessons, and to strengthen the inspection of the frequently occurring problems, which is helpful to reduce the frequent occurrence of quality accidents.
5. The quality of the quality inspector - "forbearance"
The quality inspector is an ordinary member of the company. However, his position is special. It is like an ordinary "player" in the football team and a "referee" on the field. Therefore, he should have a certain prestige to be able to Good "enforcement." The formation of quality inspectors must first rely on corporate leadership and all aspects of care, and more importantly, rely on quality inspectors to improve their quality and performance. In the event of quality problems, some leaders may not understand the facts, and will indiscriminately accuse the quality inspectors of not doing their duty, and let the quality inspection department carry the burden of “scapegoats”. At this time, “forbearance” is a calm move. It is the prestige of the quality inspectors to actively try to correct and have preventive measures. The intrinsic quality of quality inspectors is the key to establishing prestige. The working method is simple and rough, the service consciousness is poor, and the business in the first question does not know. The quality inspector who can't work independently is definitely not prestige, and sooner or later it will be eliminated.
The quality inspector's own job responsibilities determine that the quality inspector must be in charge of the work, the management, and will certainly offend many people. For the enterprise, for their own future, the quality inspectors can not do everything. The ideal person to play with, but at least to be "a useful person who can solve practical problems", must not be "useless mediocrity." In the implementation of quality management rules and regulations must be fair, just, open, not afraid to take responsibility (critical moments, dare to make a decision, come up with a feasible solution to solve the problem, even if it is not perfect or wrong, the leadership will be when you are Paying tuition fees to buy lessons, will not blame, the author has a deep understanding of this, then, the prestige of the quality inspection department will naturally be established, so that the manager is convinced, the quality inspectors will be handy when they start their work.
