Today , let’s talk about screen printing and uv printing. What’s commons and differences between them ?
Glass screen printing works by using a screen to transfer ink to the glass. UV printing, also known as UV curing printing, is a printing process that uses UV light to instantly solidify or dry ink. The printing principle is similar to that of an ordinary inkjet printer. And how about the uv printing ? Let’s talk about thiis.
differences between screen printing and UV printing
Screen printing can only print one color at a time. If we need to print multiple colors, we need to create multiple screens to print different colors separately.
UV printing can print multiple colors at one time.
Screen printing cannot print gradient colors.
UV printing can print bright and beautiful colors, and can print gradient colors in one go.
Finally, let’s talk about adhesion. When screen printing, we add a curing agent to make the ink better adsorbed on the glass surface. It won’t fall off without scraping it with a sharp tool.
Although UV printing sprays a coating similar to a curing agent on the glass surface, it is easy to peel off, so we apply a layer of varnish after printing to insulate and protect the color.
