The printing mesh is stained with dirt. What should we do?
How much dirt does the printing mesh have on your sales process? What should we do?
Mesh is heavily stained in the process of manufacturing, selling, and netting. Therefore, it must be cleaned with a degreaser before printing to obtain a perfect plate.
Second, the type of degreaser
1. Caustic soda: Nylon, Tedron, stainless steel and other mesh fabrics can be treated with 5% caustic soda solution. 2. Cleaners: Neutral detergents on the market can also be used to treat nylon, Tedron, stainless steel and other mesh fabrics. 3. Degreaser: Degreaser specially used by Screen Printing Materials Co., Ltd. is a preferred degreasing agent.
The surface of the mesh cloth is treated with a special roughening agent for surface roughening, and the main purpose thereof is to make the emulsion or the photosensitive film easy to adhere during the plate making, and to enhance the adhesive or the printing durability of the plate grinding. The emulsions or indirect films currently used have been improved much more than before. Therefore, most printing practitioners have opposed the handling of the coarsening of the mesh. The objection is that the printing durability and precision will have adverse effects after the coarsening of the mesh. Metal mesh or plating mesh should not be roughened.
1. When viewing the mesh of the frame, place it on the light table platform, or pick up the screen to face the light and see the condition of the weaving with the naked eye or the magnifying glass and the mesh. 2. Degreasing: After the mesh is wetted, the water is slightly drained, then the degreaser is poured, and the degreaser is used to draw a circle, and the brush is evenly brushed on both sides of the mesh for about three minutes. 3. After degreasing, rinse thoroughly with water with a spray gun to avoid residual degreasing agent. If it is alkaline, add 3% ice vinegar to neutralize, and then rinse with water.
1. If the net cloth is found to be damaged when it is inspected, it should be abandoned or re-opened according to the degree of damage. If it is a small part missing.
Make a mark and avoid the pattern when making plates. 2. Whether the degreasing is completely judged: if the degreasing is complete, the water will be drenched on the board, and the water will be evenly distributed when the water is drooping. If the degreasing is not complete, some parts will be drained. 3. In order to avoid damage, the general plate making does not need to be roughened, and stainless steel should not be roughened.
