Screen printing requirements for screen
Screen printing plate making, printing process, screen performance has the following basic requirements: 1.High tensile resistance.Tensile strength refers to the wire mesh by tension, resistance to damage (fracture).In addition, the screen moisture after the strength of the change should be smal...Read more -
Stretch mesh
Stretch mesh It is best to use pneumatic stretch and mesh machine, the quality requirements of stretch and mesh are as follows: 1. The tension of tension net is suitable and uniform (1) the use of pneumatic tension network when the tension requirements must be left to stand for 3-6 hours before t...Read more -
Screen version of the production process
Generally speaking, screen plate production due to the use of different photosensitive materials, its production process is also different, but no matter what kind of process, screen plate production process must be the following steps: screen and screen frame selection, pull net, wash net, coati...Read more -
Screen material selection
Currently the most used nylon mesh and polyester mesh.Nylon wire mesh heat resistance is poor, heat is easy to produce thermoplastic deformation, so that the tension is not uniform, affecting the quality of screen printing.Bonded wire mesh or screen template production is not suitable for high te...Read more -
How to control the pressure in screen printing?
Answer: the effect of pressure is to ensure network edition and printing surface full line contact, under the premise the as small as possible. Because of the pressure, the greater the scraper, though a good contact with the screen, but the mesh flattening and scraper embedded net hole degree is ...Read more -

The process of screen printing
Stretching net It is better to use pneumatic tension mesh machine. The quality requirements of tension mesh are as follows: 1. Proper and even tension (1) When using the pneumatic tension mesh, it must be kept for 3-6 hours before applying the mesh glue; (2) The stretched net shall be placed ...Read more -
Problems and countermeasures related to accuracy in plate making process
Problems and countermeasures related to accuracy in plate making process The reasons that affect the accuracy of plate making are generally summarized as follows: 1. Wire mesh, including the type of wire mesh used, the height of mesh, the fineness of wire diameter, the size of the opening area of...Read more -
Faults and causes of direct plate making
1. The loss of the sensitive film in the development cannot make the plate. (1) Under exposure. (2) The dosage of photosensitizer is insufficient or invalid, and the sensitivity is reduced. 2. The whole image produces light gray. (1) The working place of coating and drying process of photographic...Read more -
The process of screen printing
The quality of the printed matter is determined by the quality of the printing screen. How to make a high-quality printing screen is a direct issue for the printing enterprises to consider. Now let’s understand the process of screen printing. Generally speaking, the production process of sc...Read more -
Common problems and causes in screen printing
There is no ink on the surface of substrate (uneven ink leakage), the reason is: 1. The mesh number of the screen is too high, and the ink permeability is poor. 2. The sensitive film is too thick and the ink permeability is poor. . 3. There are scars on the blade of the rubber scrap...Read more -
Plastic screen printing
1. The screen printed PVC of PVC plastics was put into industrial production in 1931. PVC plastics have the advantages of bright color, not easy to crack, acid resistance, alkali resistance and low price. However, because of the toxicity of some auxiliary materials, PVC products are not suitable ...Read more
