Solving The Problem Of Stenter's Discoloration

What is the reason for the color fade after Stenter printing? Nowadays, screen printing machines are widely used in our country. On the one hand, the use of screen printing machines can speed up production power 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 silk-screen printing machinery and equipment will fade. What is the reason?

  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. Assuming that the printing material is polyethylene stock, the appearance must be flame treated before printing, which can improve the adhesion function 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 in accordance with the ink used. If the drying treatment is improper, the ink film will peel off. Generally, the printing material is textiles, which must be processed with silicon to make the material waterproof, so that poor ink adhesion will not easily occur during printing.
  4. Check the degreasing and pre-printing treatment of the printing material before printing. When the surface of the substrate adheres to grease, adhesives, dust and other substances, it will cause poor adhesion between the ink and the substrate.
  5. Improper selection of dilution solvent.

The above is all the reasons for the color fade after the Flat Screen Printing Machine is printed. We will use more advanced technology and skills to make the screen printing process more accurate, faster, and more automated.
