Everyone should be familiar with this device, although it is rarely used in our real life, but there are still many applications in the industry, because the range of applications is still very wide, but the method of operation is still If you need professional training, then let's follow Licheng Flat Screen Printer Factory to know what factors should be paid attention to when applying roll-to-roll open rotary screen printing machine?
1. The key points of the thickness of the ink layer and the occlusion rate when printing on the roll-to-roll open rotary screen printer
If the product ink thickness of the roll-to-roll rotary screen printer is good, and the coverage rate is good, the thick mesh and the mesh with large holes should be selected (that is, HD grade)
Second, roll-to-roll open rotary screen printing machine printing consumables storage standards
When printing on an open rotary screen printer or printing consumables, the temperature should be stored in a dry room to prevent ultraviolet light or strong light from being irradiated and placed flat on a clean plan.
3. The characteristics of ink printing on open rotary screen printing machine
Before printing on an open rotary screen printing machine, a screen suitable for the printing ink should be selected according to the characteristics of the printing ink.
4. Open-type rotary screen printing machine should select the screen material according to the surface of the printing process before printing
Curved surface or uneven surface should use polyester mesh with good ductility, the surface with strong absorption should select the screen with large amount of ink; the smooth surface should use high support force screen; the smooth surface should use low mesh Net; the surface of the insulating layer must be used to eliminate static wire mesh.
Fifth, the open rotary screen printing machine has a clear and good image resolution before printing:
The wire diameter is thin, the mesh number is high and the resolution is high. If the wire diameter is thick, the resolution is low when the mesh size is low. But it is not that the higher the mesh number is, the higher the ink amount is too high. The ink output caused by the ink printing is not enough, causing the mark to be damaged or damaged. In addition, under the same screen mesh number, pay attention to the harm of the wire diameter. The total width of the finest wire frame or service outlets that can be reproduced by the two types of screens are: L>2d+w, d is The wire diameter, W is the total width of the hole punching. When d>W, the total area of the wire punching hole is small, which jeopardizes the circulation of the printing ink, resulting in the serration of the wire or service network or the damage or damage of the imprint. If the mesh number is too high, the printing result will be the same as the screen.
The open rotary screen printing machine should clarify the ink printing process based on the raw materials to ensure the quality of the products printed by the open rotary screen printing machine. Although the product quality of ink printing has a certain relationship with the Open Type Rotary Screen Printing Machine, it is more related to the raw materials and ink printing process.
