Three methods to improve the ink adhesion of UV flatbed
The UV ink of a UV tablet can print on any surface, but the adhesion of various materials is different. Plates such as wood and leather have better adhesion. After the image is printed, it is not easy to peel off. However, for materials such as glass and ceramic tiles, the adhesion of the pictures will be a little worse. No matter how good, then fine prints, if you encounter rain, acid, alkaline and other objective factors, it will appear faded, if it is off, it is useless, then how to improve the UV tablet ink adhesion, the following music color UV tablet Machine manufacturers share three tips for everyone:
First, the coating: coating a substance between the ink and the substrate, which can produce the adhesion of the pigment ink, so that it can be tightly attached to the surface of the substrate, and it is not easy to fall off. Improve the seismic and compressive properties of the pattern;
The second is ink: first buy ink as much as possible to choose the original ink, this can ensure the quality of the ink, if you use some mixed ink, bad products on the world. Not only can not guarantee the adaptability of the printed pattern, but seriously affect the image quality of the pattern;
The third is varnish: varnish is a protective layer covering the surface of the pattern. It not only improves the appreciation of the substrate, but also makes it brighter and brighter. Moreover, the pattern has the function of waterproofing and sun protection. Of course, a good pattern can also adapt the case to a strong acid, strong alkali, low temperature environment.
