What Is The Reason For The Color Discoloration Of The Screen Printer Equipment After Printing?

What is the reason for the color discoloration of the screen printing machine after printing? Nowadays, the screen printing machine has been widely used in our country. On the one hand, the use of the screen printing machine can speed up the production efficiency to a certain extent and achieve better economic benefits. On the other hand, it is more conducive to spreading some knowledge. Sometimes the products printed by the screen printing machinery and equipment will have the problem of color fading. What is the cause of this? The following is an introduction:

1. Materials such as glass and ceramics must be sintered at a high temperature after printing, as long as the temperature treatment is appropriate, the adhesion will be good.

2. Insufficient adhesion of the ink itself causes the ink film to not be firmly fixed.

3. If the printing material is polyethylene strands, the surface must be flame treated before printing, which can improve the adhesion of the ink during printing; if the printing material is a metal material, it must be degreasing and dust removal before printing. After printing, it is dried according to the ink used. If the drying treatment is improper, the ink film will peel off. Generally, textiles must be processed with silicon to make the material waterproof, so that poor ink adhesion will not easily occur during printing.

4. Degreasing and pre-printing inspection of the printing materials before printing. When grease, adhesive, dust and other substances are attached to the surface of the substrate, it will cause poor adhesion between the ink and the substrate.

5. Improper selection of dilution solvent.
