Silk screen printing supplies introduction:
1, screen printing supplies selection
Nylon mesh, polyester mesh, stainless steel wire mesh, nickel-plated polyester mesh, plain weave, twill weave, semi-twisted weave, full twist weave. When the white screen is exposed, it is easy to cause diffuse reflection, and the golden, red and amber colors absorb ultraviolet rays, which can prevent halo.

When the net is stretched, the net frame is cleaned first, and the stretch net can be manually, mechanically or pneumatically applied, and then bonded and trimmed after stretching. Stretching net requires proper tension of the screen, uniform and stable, consistent filament, avoiding diagonal pulling, and the warp and weft are parallel.
3, printing consumables screen directly plate making
First, the photoresist is coated on the screen, and the computer controlled laser of the prepress system is imaged on the screen to make a screen version. This plate making method uses a special photosensitive adhesive, and the ultraviolet light wave range is narrow, and the laser exposure system is expensive. The inkjet imaging system first applies a photoresist on the screen, and the prepress system computer-controlled inkjet system sprays the light-blocking ink onto the photosensitive layer of the image, and then the ultraviolet light is fully exposed. The image is not sensitized, the photoresist is washed away; the blank portion is photohardened. This method can be used with ordinary photosensitive glue without losing the details of the image.
