Does anyone know how the advertising logo on the transparent umbrella is printed? Is it printed by screen printing technology?

It is screen printed, and thermal transfer can also be used. However, most of the silk-screen products can be printed before the finished umbrella, which is a batch, or printed after the finished umbrella. These products are used by scattered customers for publicity and advertising. After the finished umbrella is printed, you need to make a relative workbench, otherwise it will be difficult to print.
