Sublimation printing on to dark surfaces
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.
1. A cup on to which an image is thermally transferred, comprising:
a base layer extending around an outer peripheral surface of a cup body;
a darkened color surface treatment layer disposed on the base layer;
a screen printing layer disposed on the darkened color surface treatment layer;
a resin layer disposed on the screen printing layer; and
a thermal transfer layer that accepts the image.
2. The cup of claim 1 , wherein the darkened color surface treatment layer, the screen printing layer, the resin layer, and the thermal transfer layer covers a subset area of the outer peripheral surface of the cup body.
3. The cup of claim 1 , wherein base layer of the cup is stainless steel.
4. The cup of claim 1 , wherein the screen printing layer is colored white.
5. The cup of claim 4 , wherein the screen printing layer includes two separate layers.
6. The cup of claim 1 , wherein the screen printing layer is at least one area encircling an entirety of the outer peripheral surface of the cup body.
7. The cup of claim 1 , wherein the screen printing layer is at least one area encircling less than an entirety of the outer peripheral surface of the cup body.
8. The cup of claim 1 , wherein a subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is circular.
9. The cup of claim 1 , wherein a subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is elliptical.
10. The cup of claim 1 , a subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is polygonal.
11. The cup of claim 10 , wherein a shape of the subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is a square.
12. The cup of claim 10 , wherein a shape of the subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is a rectangle.
13. The cup of claim 10 , wherein a shape of the subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is a triangle.
14. The cup of claim 10 , wherein a shape of the subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is a trapezoid.
15. The cup of claim 10 , wherein a shape of the subset area of the outer peripheral surface of the cup corresponding to the screen printing layer is a star.
16. The cup of claim 15 , wherein the star shape of the subset area of the outer peripheral surface of the cup is five-pointed.
17. The cup of claim 15 , wherein the star shape of the subset area of the outer peripheral surface of the cup is six-pointed.
