What is the clothing gilding in the print?



In the clothing printing, bronzing paper and hot stamping gold paste can be simply understood as bronzing is a small branch of the printing process. They are a post-process of fabric and leather surface treatment. For details, you can go to Dongguan Zijiang Textile to see There are a lot of hot stamping pictures on it. Hot stamping is mainly to achieve the effect of sparkling in the sun, which is not possible with general flat printing. Daily bronzing pattern and printing knowledge
The printing is divided into digital printing, which is also our common large direct-injection printing, and the pre-requisite group of common flat nets and rotary nets is made into a screen version, and the pattern on the screen is printed on the cloth or leather. . The principle of bronzing is similar to this. Simply speaking, the pattern is prefabricated on a plate (commonly intaglio), by applying glue on the plate, and then transferring the gold on the bronzing paper to the cloth according to the pattern of the plate. Just called bronzing, the simple is to understand this.

Digital toner hot stamping is prone to incomplete hot stamping, overprinting machine is not complete solution

    1. The plate is damaged or deformed, which is one of the important reasons for the incompleteness of the digital toner laser printing. Therefore, if the plate is found to be damaged, the plate should be repaired or replaced immediately. The plate is deformed so that the plate does not withstand the applied stamping pressure. The plate should be replaced and the pressure adjusted.

      2. If the gilding paper is cut and conveyed, the gilding paper will be too small when the horizontal cutting is cut or the deviation will be caused when the cutting is performed. The gilding paper will not match the printing plate, and some of the graphic will be exposed. And caused incompleteness. In order to prevent such problems, it should be neat and flat when cutting the hot stamping paper, and the margin size should be appropriately increased.

      3. The improper transfer speed and tightness of the bronzing paper will also cause such a malfunction. The bronzing paper receiving device is loosely displaced, or the winding core and the reel are loosened, the unwinding speed changes, and the tightness of the bronzing paper changes, causing the image position to deviate, resulting in graphic defects. At this time, the winding and unwinding position should be adjusted. If the hot stamping paper is too tight, the pressure of the winding roller and the pulling force of the winding roller should be properly adjusted to ensure proper speed tightness.

      4. The printing plate part moves and falls at the position of the bottom plate, and the pad of the embossing mechanism shifts, so that the normal hot stamping pressure changes, and the unevenness will cause the digital toner to print the hot stamping part of the image. Imprinting is incomplete, such as too light pressure, can increase the pressure.
