In the screen printing industry, accurately selecting the appropriate CCD screen printing machine model and configuration based on the complexity of the printed pattern is the key to ensuring printing quality and production efficiency.
Firstly, it is necessary to assess the complexity of the printed pattern. Simple patterns usually have simple lines and single colors, and have relatively low requirements for the accuracy and functionality of screen printing machines; Complex patterns may include fine lines, tiny text, multi-color overprinting, and gradient effects, which require screen printing machines to have higher precision and more functions.
For printing simple patterns, the basic CCD screen printing machine can meet the needs. This type of screen printing machine usually has a conventional positioning accuracy, such as ± 0.1mm, which can achieve basic visual positioning function and ensure accurate pattern printing position. In terms of configuration, ordinary scraper systems, such as rubber scrapers with moderate hardness, combined with conventional ink supply systems, can ensure uniform ink coating and achieve stable printing effects. The screen selection is also relatively broad, generally a mesh size screen is sufficient.
When faced with patterns of moderate complexity, such as those with thin lines and a small amount of multi-color overlay requirements, it is necessary to choose a screen printing machine with higher positioning accuracy, such as models with an accuracy of ± 0.05mm. In terms of configuration, a more sensitive CCD visual recognition system should be equipped to quickly and accurately identify the positioning marks on the substrate. The scraper can be made of higher quality materials, such as polyurethane scraper, to ensure more uniform and stable wiping of ink during the printing process. At the same time, the ink supply system should have better flow control functions to meet the precise supply of ink of different colors.
For highly complex patterns, such as high-precision electronic circuit board printing, top-level CCD screen printing machines must be selected. The positioning accuracy of this type of screen printing machine can reach ± 0.01mm or even higher, equipped with advanced image recognition algorithms and high-speed processing chips, which can complete the positioning and calibration of complex patterns in a very short time. The scraper system needs to have automatic pressure adjustment and multi angle adjustment functions to ensure the best printing state when printing fine lines and complex surfaces. The ink supply system should achieve fully automated and high-precision control, precise to the supply amount of each drop of ink. In addition, it is necessary to equip high-precision screen tension control system and advanced screen cleaning equipment to ensure the stability and cleanliness of the screen, thereby ensuring the consistency and stability of printing quality.
In short, selecting the appropriate CCD screen printing machine model and configuration based on the complexity of the printed pattern requires comprehensive consideration of multiple key factors such as accuracy, visual recognition system, scraper, ink supply, etc. Only in this way can efficient and high-quality printing production be achieved.
