screen printing polyester mesh
Ordinary polyester mesh: woven from ordinary polyester fibers.Advantages: A.High tensile strength, able to withstand high tension B.Good wear resistance, can withstand printing ink pigments and squeegee on the screen wear.C.High light resistance, in natural room temperature light.Long storage per...Read more -
Problems and solutions in screen printing process
Printing plate development is difficult. Causes: (1) too long exposure time. (2) after scraping, stored for a long time. (3) excessive drying temperature causes thermal crosslinking. (4) the photosensitive adhesive has been exposed. (5) when the bottom plate and film contact is not solid. (6) fai...Read more -

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 -
