Abstract
A heat transfer process on to a stainless steel cup with a dark surface involves a stainless steel dark surface treatment layer arranged on a base layer of the outer circular surface of the cup body. The stainless steel dark surface treatment layer is sequentially arranged as at least one wire screen printing layer, a resin layer, and a thermal transfer image layer. The is one or several screen printing layers on the dark rough surface to fill up the rough pits on the dark surface to form a smooth surface and then a thermal transfer resin coating is applied, followed by heat transfer printing. A colorful personalized product can thus be produced from the cup.
