1. Direct printing: it can be printed directly on the cup by pad printing or curved surface printing machine. The technology is suitable for simple pattern and small batch production. Baking depends on the choice of coating.
2. Water transfer printing: first print on the water transfer machine, and then screen printing and spray printing. Then put the printed water transfer paper into the water, separate the pattern from the paper, transfer the pattern to the cup and bake the finished product.
