Embodiment Construction
[0018] The thermal transfer printing process on the metal sheet includes the following steps:
[0019] 1) Use thermal transfer ink to offset graphics and text on uncoated paper. The paper can use 70g double-adhesive paper. Thermal transfer ink has thermal sublimation performance. After reaching a specific temperature and time, the ink molecules will volatilize and transfer. onto the substrate;
[0020] 2) Contact the printing surface of the paper with the coating surface of the metal plate provided with the coating, and use the heating element of the heat press machine to heat the metal plate evenly; the metal plate here can be aluminum plate, copper plate or iron plate, etc. The coating set on the board is PE polyester paint, which can absorb ink molecules very well, and can be fused with ink molecules to form firm and vivid pictures and texts after fusion; the heat press machine adopts Zhengke automatic Four-station heat press machine, when the heating element of the heat p...

The invention belongs to the field of printing technology, and particularly relates to a thermal transfer process on a metal plate. The thermal transfer process comprises the following steps that: 1) images and texts are offset-printed on uncoated paper by use of thermal transfer ink; 2) the printing surface of the paper is in contact with the coating surface of the metal plate with a coating, and the metal plate is uniformly heated by use of a heating element of a pyrograph machine; and 3) after the heating is finished, as the thermal sublimation performance of the thermal transfer ink, the images and texts printed on the paper are transferred to the coating surface of the metal plate, and the operation is over. The thermal transfer process provided by the invention makes up the shortcomings of the traditional thermal transfer process, and restores patterns with vivid colors on the metal plate; and moreover, due to the specific surface treatment of the metal plate, the patterns are firmly attached, and the color does not change easily, thus the metal plate is a material which is very practical in the field of home improvement. More focuses are placed on the environment friendliness and durability of materials in the existing field of home improvement, and the metal plate is utilized almost everywhere; and as the metal plate is firm, durable, nonflammable and environment-friendly, the metal plate becomes more and more popular.
Description
technical field [0001] The invention belongs to the technical field of printing, and particularly relates to a thermal transfer printing process on a metal plate. Background technique [0002] At present, thermal transfer technology is mostly used in clothing, toys and other fields.
