Thermal transfer technology has not been popularized and used in China for a long time, and it is also a new type of process that has only been used in the production of signage graphics in recent years. Why is the graphic production process of thermal transfer and water transfer used in the production of signage graphics? On the one hand, the quality requirements for high-quality signage graphics are getting higher and higher. In addition, the application of new technologies in the production of signage is also the development of science and technology, which brings new development opportunities for the signage industry.
Generally, the production process of large outdoor metal signs can be divided into three major processes: skeleton welding, surface processing, and graphic production. The so-called graphic production refers to the production of the layout information of the sign, which is the main way to transmit the information of the sign. Strive for simplicity and accuracy. Generally, the two most commonly used graphic production methods for sign manufacturers are screen printing or UV printing. These two sign graphic production processes have their own advantages and disadvantages. For example, UV printing is generally used to make small plane logo graphics, while silk screen printing In theory, screen printing is not limited by the size and shape of the signboard. Secondly, the whole process of UV printing signage graphics and text is completed by machine, which is highly efficient, while screen printing requires plate making, which is basically completed manually throughout the entire process, which is inefficient. However, the common disadvantage of the two is that the color and accuracy of the graphic information is low, and it is not suitable for the production of signage graphic information with rich colors and high picture accuracy. And thermal transfer technology also solves this problem.
