There are many people who use screen printing, and they often encounter discoloration. How can it be stronger if it fades?
Using high-quality screen printing, the resulting product can achieve bright colors and accurate overprint. This is a very small number of technical issues. Let's talk about solving the screen printing without fading. This is determined by the process of screen printing and the inks you use.
First, we clean up the printed side of the substrate. I would like to ask, if there are dust and other debris on the surface, why does the screen printing ink have adhesion, and how can it not fade?
Second, use professional ink printing. Ensure
excellent adhesion. Use PP ink for PP profiles. Before printing, use PP water. ABS uses ABS ink.
Third, the product must be degreased before printing. Because its surface is covered with a layer of grease, the ink will not be fastened.
Fourth, one of the printed products is not very smooth and hard. Not as good. Glass screen printing, metal screen printing, etc., we first need to choose the corresponding ink, and then add a curing agent, so that the screen printing ink adhesion is very strong.
Many friends will say why the patterns I printed fade. This is because the screen printing screen you use and your printing method may be wrong. But sometimes it is dropped for some other reasons. Maybe your screen quality is not very good. So be sure to choose a regular screen printing screen.
