CD screen printing process and corresponding points analysis four

Paste

Sticking the net is actually a very important process, and everyone should pay enough attention. Many defects in the printing process are caused by the lack of attention when sticking the net. Sticking to the net should be done in the same way that the sharpening knife does not mistakenly cut the firewood. Some areas where the photosensitive layer is often damaged during printing should be protected before the machine is put into use. The edges of the inner and outer rings of the film are the two areas that should be protected. When affixing the web, different machines should also be considered for different adjustments to the stencil of the screen. Thickness of ink also has a certain influence on the distance of the position where the edge is affixed.

Printing operation requirements and precautions

The specific work of the printing operation is relatively trivial. The scope of the operation is relatively wide, the content is also more, and the production equipment is fast. The quality control has a strong dependence on people. These objective reality forces each operator to guarantee the quality and security of the work. In order to complete their own work in a proper way, they must be fully focused, dedicated, and responsible. In fact, diligence, carefulness, dedication, and due diligence are essential qualities for doing this work. Carelessness and careless style of doing things are out of tune with the line. In terms of the specific details of operation, different people have different styles but measure the pros and cons. There is only one standard: fast, accurate, and high pass rate. Different operating styles should learn from each other, learn from each other, and try to improve their own operation level. The company will evaluate the operation level in the future. For use with quality materials.

Regardless of style, the following requirements and issues should be implemented in the printing process outlined above.

1. The operator should master the functions and operating methods of some commonly used buttons and components on the printing press.

2. When the screen is in alignment, the graphic and textual alignment should be accurate. In addition to the special effects, the entire disk heart and graphics should not be eccentric and partial.

3, The printing effect should follow the sample, but when the sample is left for the first time, the disc whose printing effect tends to be stable should be selected, and the specification, model, and deployment method of the material used for proofing shall be marked in detail on the sample disc.

4. When adjusting the oil, records should be made, and the proportioning amount and the materials used should be recorded in detail in the oil-adjusting record book or sample plate labeling paper. This can provide convenience for repeated production. When adjusting the oil, the amount should be estimated based on the quantity of the order so as not to waste the ink.

5. Check the hygienic conditions of the large turntable and the base of the printing press before starting the printing process and do the timely processing. Any irregularities on the big turntable for any reason will cause serious damage to the doctor blade and screen. If the undried ink on the pedestal is not treated in time, it may cause ink spots on several hundred genuine information surfaces.

6, when the material should be used to blow off the dust on the disc. Because the top surface of the top plate of each dish and the bottom surface of the information surface are most likely to get dusty, it is important to blow.

7. In the current staffing situation, the operator should reasonably allocate the time spent on each work due to the need to take into consideration the feeding, sampling inspection, packaging, refueling inspections, etc. to avoid misconduct, and to detect defects in time. . To reduce the defective scrap rate to a minimum.

8. Packing and packing should be carried out according to the company's and customer's requirements. See the packing standard for specific conditions.

9. After the test of positional printing, all test plates on the machine should be cleaned to be genuine. If it is necessary to re-align the screen-changing version, the genuine unloading should be transferred back to the tote.

10, in order to prevent the mixed dish in the boot before the production of genuine products to deal with the feeding area, cutting area, defective material storage column, packing station and other areas of the trial printing plate thoroughly cleaned.

11. In order to prevent the mixed dish from being printed, it is only possible to use the position of the disc that has been marked with a marking stroke to test. The sample plate used for the plate should be marked on the printed surface with a marker pen "like".

12. In order to prevent Zhang Guan Li from officially printing authentic products, it is necessary to check carefully whether the printed content is consistent with the content of the bare disc. You should develop the habit of looking at the mother-of-message markings on the information surface when loading materials. DVD discs are not easy to distinguish between the information surface and the printing surface before printing, and it is necessary to distinguish the pros and cons when looking at the master code.

13. Do not stand or sit on the packaged disc. In order to avoid causing scratches on the disc.

14. When handling packed discs, they should be handled with care, and they must not be thrown or thrown at random so as to avoid cracking and scratching of the discs. And the highest stacking time can not be stacked.

15. Be sure to pay attention to safety first when operating machinery and equipment.
