Screen printing is a common printing method. To obtain high-quality printing results, you need to pay attention to the operating details of each process. Let's find out today, how can we improve the accuracy of screen printing?

1. The printed screen frame material has a great impact on the final effect. When printing, you need to choose a high-quality print material. Commonly, there are hard alloy aluminum materials such as LY12 and LF2.

2. Nylon wire mesh and polyester wire mesh are currently used in relatively large quantities, and have different characteristics. After the nylon mesh is heated, it will have a certain deformation and uneven tension, which will adversely affect the printing effect. The polyester screen has good heat resistance and can maintain good stability after being heated. When printing, you need to choose the right material according to the actual needs.

3. Screen stretcher is very important in screen printing. The tension of the stretched net needs to be adjusted. If the tension exceeds the tolerance range, it will easily cause the screen to become brittle or broken.

4. During the printing process, it is also necessary to prevent the stretched net from slackening, and to avoid the uneven printing quality.

5. During the printing process, strict control of equipment and scraping pressure is also required.

6. The printing materials used for screen printing need to have good chemical stability and suitable drying speed.

7. The hardness of the scraper should be controlled between A60 ~ 80, which can reduce the distortion of the pattern. In addition, it is necessary to accurately grasp the angle. It should be greater than about 20 °.
