Welcome to the Xianghuai Website.We are mainly engaged in designing and manufacturing flexographic printing machines.

In the process of printing with a flexographic printing machine, in order to ensure good printing results, it is very important to adjust it reasonably. How do we effectively adjust the flexographic printing machine during the actual printing process? What? Let's take a look at it together.

1. Scratch preparation:At present, soft and hard is a moderate polyurethane oil-resistant rubber fire-resistant silicone rubber scraper.The scraper hardness is calculated in Shore hardness. Generally divided into four grades, 40-45 degrees for low hardness scraper, 50-55 degrees for soft hardness scraper, 60-65 degrees for medium hardness scraper, 70-75 degrees for hard scraper. The printing platform should use a large-sized squeegee with a thickness of 10-12 mm.The length of the squeegee depends on the size of the frame, and is generally 20-30 mm wider than the sides of the figure.

2. Upper version:Find a good rule line and determine the mesh distance. The network distance is generally required to be accurate. In order to achieve good overprinting accuracy, the mesh distance should be set lower, about 3-4mm, the small net frame is set to 2-3mm, and the large format can be set higher, 5-6mm. The parameters of the grid spacing are determined according to the size of the screen and the tightness of the stretcher.

Therefore, the adjustment work of the flexographic printing machine can ensure the quality of the flexographic printing machine more effectively, so as to meet the printing demand of people.
