Talk about how to stabilize and improve printing quality

The quality of printing is determined by three major factors: printing machinery, printing materials and operators. In the actual work, we must ensure stable quality and achieve high-quality printing. On the one hand, it is necessary to meticulously debug the printing machinery so that it is always in good condition; on the other hand, it is necessary to strictly procure printed materials. What is more important is the quality and strict management of the operators. Quality management is a long way to go, and the self-management of operators is also Very important.

1. Quality awareness

Operators’ quality awareness is the key to affecting product quality. Operators should try to avoid and reduce work errors in their work, first ensure and improve work quality, strictly meet requirements, perform due diligence, and work meticulously. Without product quality, there is no product quality. Without product quality, our quality of life cannot be guaranteed. It is very important to strengthen the staff's business skills training and quality standards learning. The combination of theoretical study and practical work gradually brings the overall business skills to continuous improvement, so that the quality consciousness is continuously strengthened in the employees' minds. It is inevitable that mistakes are made in the work. It is not terrible to make mistakes. It is good to change them if they are no longer guilty. What is terrible is that the same mistakes are made again and again, and some are still low-level mistakes. These are all caused by insufficient ideological understanding. If they are wrong, they must be changed. Wrong should be punished, quality management should be strict, rewards and punishments should be strengthened, and small mistakes must be grasped to prevent small mistakes from contributing.

2. communicate with each other

In the work, communication between the operating personnel is very necessary. Although the application of ERP helps a lot in production and quality, it is also important to communicate the language, thoughts, and emotions among the personnel. All departments should report problems in a timely manner. Timely processing can only avoid the occurrence of major accidents. Sometimes the results of one sentence and one sentence at the time of handover may be different. Each process should have more self-examination, reflection, understanding and collaboration, fewer errors, complaints, evasion and accusations, dare to take responsibility, and do not forget us As a whole, our products represent Xinhua's reputation and brand.

3. Lessons learned

The work should be summed up in a timely manner. In the printing process, many quality problems are caused by the negligence of the operators. We all know the word “black letters on white paper”. Printing is doing such work. The problem is that it is difficult to make up for and change the loss. Therefore, firstly, the construction list and proofs should be correct and correct, and the quality of the batch should be eliminated and the customer's rejection loss should be eliminated. The second is that the printing press station should strictly follow the requirements of the construction list and proofs and the quality standards. It is necessary to formulate corresponding preventive measures for the error-prone parts. Great attention is paid to the fact that the printed materials are inconsistent with the materials and the requirements are not the same. A fixed way to operate, if the operator can not be a specific analysis of specific product quality, use appropriate methods to print, you can not print high-quality products, for example, according to the color requirements of the same sheet to determine the size of the ink in each group And the proportion of the fountain solution; adjust the flowability and printing pressure of the ink according to different paper properties; sometimes it is necessary to adjust the printing sequence according to the proof requirements and the characteristics of the paper; it is necessary to print the special paper and the paper before the company does not use paper. The inks used by companies are tested for drying speed and brightness. If the effect is not ideal, replace the targeted inks in time to avoid loss. In short, the operator should be based on different quality requirements, specific analysis, treatment, flexibility and resilience, experience is constantly summed up in the work.

The normal operation of the equipment has a direct impact on the printing quality. Equipment that is sick is not a good product, and the operating status of the equipment is inseparable from the operator's reasonable adjustment and routine maintenance. Eliminating man-made damage equipment, reasonable and safe use of the equipment is what every operator must do, such as the pressure adjustment between the rollers and the pressure adjustment of the ink roller, the oil and the maintenance of the rotating parts of the bearings and equipment, and the equipment maintenance is also to reduce the printing cost. The focus of product quality assurance should be given high priority.

5. Several points should be noted in the printing process:

(1) Produce strictly in accordance with the construction sheet, sample sheet requirements and quality standards; (2) Do a good job of sampling proofreading in the printing process. Sampling a certain number of printed sheets at regular intervals to check whether the ink color is the same as the sample sheet and whether the printed matter is sticky. Dirty, dirty spots, whether the rules are the same, whether the handwriting is clear, etc., and do a good job of inspection records, if necessary, increase the frequency of sampling; (3) pay attention to ink and water balance, timely adjust the amount of water and ink; (4) do a good job equipment Maintenance work, often check the oil tank storage, when it is insufficient, should be promptly added; regular refueling of the bearing and equipment rotating parts to ensure that machinery with oil work to avoid excessive wear and tear of the machinery; often pay attention to whether the device has abnormal noise; daily cleaning equipment Paper powder and oil stains.
