Thermal transfer printing technology for thermos cups is a printing process that transfers patterns onto the surface of thermos cups. Heat transfer printing technology is widely used in the decoration of thermos cups due to its high efficiency, долговечность, and diversity. The following is an introduction to its related features.
1. Principle
By printing sublimation transfer ink onto paper or plastic film, and then overlapping the printed image and text on the paper or film with a thermos cup and heating and pressing it together, the dye on the paper or film will sublime in a gaseous state, penetrate into the molecular structure on the surface of the thermos cup, and form a brightly colored image after condensation.
2. Operation process
Firstly, the printing paper process involves printing the pattern to be transferred onto a polyvinyl butyral film. Следующий, use the sticker paper, prepare the corresponding product mold, print and cover with oil, and after drying, stick the sticker paper onto the product. Then bake the flower paper at a high temperature of 520-600 degrees Celsius to obtain the finished product.
3. Характеристики
(1) Преимущества: The transfer image has bright colors, rich layers, and effects comparable to printing. It can present complex effects such as gradient and blending, and can create multi colored patterns in one go without the need for color matching. Easy to operate, with fewer production processes and higher efficiency.
(2) Disadvantages: The process is relatively complicated, the scrap rate is high, and it requires labor. It can only achieve a flat effect and cannot meet the requirements of relief technology. The material requirements for the product itself are relatively high, and some heat-resistant products are not suitable for heat transfer printing. If the transfer printing technology is not up to standard or if it is used for a long time, the pattern may peel off.
