The wide application of UV flatbed in various industries is favored by many customers, but UV flatbeds sometimes show peeling and ink shedding when printing glass and ceramic tiles. What is the specific cause? Here are a few reasons why Xiaobian will give you a summary after consulting with the technical staff:
1: The ink chemical reaction is not complete. Due to the long-term exposure to humid air, the ink is oxidized and chemical reaction causes the tiles and glass to fall off and peel.
2: The characteristics of glass and ceramic tiles themselves. When the air humidity exceeds 65%, the moisture will make the surface of the glass tile wet. If the printing is not performed, the printed pattern will be deteriorated due to the moisture, which will cause the adhesion of the ink to deteriorate, causing the peeling and peeling of the tile and the glass. ;
3: Coating factor. Before printing, we have to make the coating of the article uniform, not only the partial coating;
4: varnish treatment. After we have finished printing the glass and tiles, we should dry them in time and spray them with varnish. This can both protect and improve printing results;
These are some of the factors related to ink shedding and peeling. As long as we can pay attention to these reasons before printing, the printed items can prevent this from happening.
