new idea for printing

Hot first and then printing is a new idea in the tobacco label design and printing industry.
The application of the process is very high requirements on anodized aluminum, the key to the process is anodized aluminum hot stamping must be firm, when printing anodized aluminum must not be printing ink back down.
Pull back not only affects the quality of the cigarette, and pull back down the anodized aluminum will soon pile up in the blanket, light will cause the loss of image dot, heavy will cause the local image can not be printed, with the operation of the machine, anodized aluminum powder will also be transferred to the ink roller system, accelerate the wear of the ink roller.
Therefore, this process should be based on the characteristics of printing paper, the selection of appropriate anodized aluminum, to ensure that anodized aluminum can be firmly attached to the surface of the paper.

In addition to the production of the bronzing position to achieve accurate, smooth surface, pressure balance, uniform, not foaming, not paste, and other requirements, but also the special requirements of the bronzing pattern edge can not have obvious indentation, bronzing anodized aluminum in the hot stamping surface to have good adhesion, as well as no obvious scratches and scratches and other phenomena.
As we all know, the stamping process is actually a paper heating and compression process.
For the white card, glass card, especially to pay attention to the protection of semi-finished products, the production process to minimize the deformation of the paper of all kinds of adverse factors, so the smooth process after the bronzing and product pass rate has a great help.
