The automatic screen printing machine uses the basic concept that a part of the screen mesh of the screen plate can penetrate the ink and a part of the non-text screen can not penetrate the ink. To exceed the actual effect of good printing, we must manipulate the pressure of screen printing. So how to control the pressure in the printing of automatic screen printing machine?

In screen printing, suitable and well-balanced printing pressure is the key to ensure high-quality screen printing. If the printing pressure is too low, the printing plate can not touch the printing process and the printing cannot be performed, resulting in the situation that the printed text is not detailed and the ink thickness is uneven. Common printing failures such as blurred printing patterns, severe damage to screens and doctor blades. If the printing pressure is uneven, a large number of common printed matter failures will occur. Therefore, manipulating the elements that jeopardize the printing pressure and improving the unevenness of the printing pressure has become the main problem to be dealt with by the screen printing process.

The effect of the printing pressure of the automatic screen printing machine is to ensure that the screen and the printing process surface have sufficient line contact, and the lower the condition, the better. Due to the greater pressure, although the scraper is in good contact with the screen, the flattening level of the wire mesh and the level of the scraper inserted into the mesh are high, so the amount of ink transfer is small, and the deformation of the scraper will also be greater The situation of oil filling causes great harm, and will also expand the deformation of the screen, and the sliding friction between the scraper and the screen will also increase, which not only increases the friction of the wire mesh, but also jeopardizes the line scraping rate of printing .

In the entire process of screen printing, the scraper and the screen are in contact with each other and cause pressure, then the scraper will be damaged after being applied frequently. At the same time, the application will inevitably impact the scenery, so the scraper will show scars, and the scraping blade will damage the copying effect; therefore, before copying, you need to check the vertical, sharpness and shortcomings of the scraper sealant wound.

After the blade is damaged, it needs to be repaired and then applied. The repair is divided into technical repair and mechanical equipment repair. Generally speaking, the skill of sharpening will damage the effectiveness of sharpening due to the unfocused focus point and pressure of the scraper. In order to ensure the vertical edge of the blade, you can generally paste sanding paper on a flat wood board and follow In the milling direction, a wall panel standing upright with the milling plate is set up. The scraper blades of mechanical equipment grinding are well-proportioned and solid, which is better than skill grinding. In practice manufacturing, the scraped blade should also be inquired.

The scraping pressure of the rubber scraper has an immediate contact with the delivery of the ink. The greater the scraping pressure, the greater the amount of ink delivery. The spread of the mill causes the expansion of the business network, and the print mark is not clear when the optimism is not optimistic; the pressure of the scraping The smaller, the smaller the amount of ink delivered, which will show that the business network is not clear or the impression is not detailed.
