On the closures of jars, not only pad printing is applied, but also silk-screen printing. Silk-screen printing does not obscure the color and beautiful surface of the closure, as often happens with the label. The closures have a matte or glossy surface, so using silk-screen printing you emphasize the beauty of this surface.
When creating a design, pay attention to its placement: some closures may have an injection point in the center of the surface. Avoid placing the design in this point, as it couldn’t be printed on the hole.
