Automatic screen printing machine is a kind of high-precision printing equipment, which can be used to print various materials and products. In carrying out the printing process, how to ensure the printing quality is very important. The following will discuss from some key factors.
First of all, the mechanical structure and control system of automatic screen printing machine is one of the key factors affecting the printing quality. The mechanical structure should be designed to be stable and precise, and have the appropriate printing speed and strength adjustment function. At the same time, the control system needs to have high-precision position control capability, which can accurately control the position and moving speed of the printing head to ensure the clarity and accuracy of the printing pattern.
Secondly, the quality and characteristics of screen printing ink is also one of the important factors affecting printing quality. When choosing screen printing ink, you need to consider its performance in terms of color stability, adhesion and durability, and choose the right ink according to different printing materials and product types. Meanwhile, the viscosity and fluidity of the ink also have an impact on the printing results and need to be reasonably regulated and controlled.
In addition, the quality of the printing plate and screen will also affect the printing quality. The printing plate is the carrier of the pattern, which needs to have certain flatness, hardness and abrasion resistance. The screen, on the other hand, is the key component for transferring the ink to the printing material, and its mesh size and shape have an important impact on the printing effect. Therefore, making and selecting high-quality printing plates and screens can improve the printing quality of screen printing machines.
In addition, the control of the on-site environment is also an important factor affecting the printing quality. For example, the control of temperature and humidity can affect the fluidity and drying speed of the ink, and it is necessary to maintain a suitable temperature and humidity range. In addition, purification of the printing area and static control can also reduce the impact of dust and fibers on printing quality.
In addition, the technical level and experience of the operator is also one of the key factors to ensure the printing quality. Operators need to be familiar with the operating principles and operating procedures of the screen printing machine, and be able to adjust and control according to the actual situation. At the same time, operators need to have good observation and judgment, timely detection and solution of problems in the printing process, to avoid defective products.
Quality control and testing is also an important means to ensure the quality of printing. Through the establishment of reasonable testing points and indicators, and regular testing and recording, can be timely detection and correction of quality problems in the printing process. For example, human eye observation and optical microscope and other means can be used to test the quality of printed materials, but also through the colorimeter and other instruments to measure and judge the color and color difference of printed materials.
To summarize, the key factors to ensure the printing quality of automatic screen printing machine include the design of mechanical structure and control system, the selection and control of screen printing ink, the quality of printing plate and screen, the control of the site environment, the experience and technical level of the operator, and quality control and testing. Only by ensuring good quality control and management in all aspects can the printing quality of automatic screen printing machine be guaranteed to a certain extent.
