What about the key points for selecting flour mesh?...

Bolting cloth can be used in CMYK works. The plate making processes are as follows when using bolting cloth.

Stretching stencil → washing net 1 → drying → scraping photosensitive glue → drying → drying net → washing net 2 → drying → screen making success

1. stretch stencil, welding square frame with square steel, using mesh mesh Stretched on the frame, the mesh number of the screen printing mesh can be selected according to the needs, but generally use 250 objects more, the number of meshes is too small, the quality of screen printing is low, the number of meshes is too much, the ink is required to be good. The ink is not good enough to have a mesh number, which will affect the ink, which also causes poor printing quality. The stretcher should be stretched and the mesh stretched too loose to finish the screen printing normally. A good screen version will have a degree of relaxation and good flexibility.

2. wash the net 1, clean the mesh, wash away dust and impurities.

3. drying, can be dried under the sun, can also be blown dry with a hair dryer, or baked with baking equipment, pay attention to temperature when baking, carefully damage the mesh.

4. scraping photosensitive adhesive [2], the photosensitive adhesive used here is generally a single-liquid type photosensitive adhesive, which is added with a photosensitizer, will be solidified after exposure to ultraviolet light, forming a dense solid colloid. Therefore, when the photoresist is scraped, it should be carried out in a closed room to prevent the sunlight from being irradiated, and an incandescent lamp can be installed in the room to illuminate.

5. drying, this drying is different from the last time, this drying must be done indoors, to avoid contact with ultraviolet light.

6. drying net, drying the net requires a four-sealed airtight, UV lamp installed at the bottom, a box on the top of the glass. Place the film on the glass, cover the film that needs to be dried with a mesh cloth, press it with a heavy object, and then turn on the ultraviolet lamp, and illuminate the appropriate time. It should be noted here that when turning on the ultraviolet light, people should stay away from the drying net to avoid the damage of strong ultraviolet rays.

7. Washing net 2, the purpose of this washing net is to wash away the unhardened photosensitive glue that is not irradiated by ultraviolet rays, so that a dense mesh having a graphic shape is formed on the stencil.

8. Dry the stencil again. This time, because it has been dried, it can be placed in the sun.
