Because the hot stamping pressure is correspondingly higher than the printing pressure, in order to avoid burrs on the edges of anodized aluminum due to the compression deformation of packaging, the packaging pad (pad) should be made of medium-hard materials with small deformation coefficient and good flatness, so as to ensure the hot stamping effect and make the quality of batch products consistent.

Matters needing attention in color printing

In the process of color plate making, if the screen angle is not arranged correctly, it will affect the printing color effect, and in serious cases, it will also produce turtle veins. Four-color plate-making printing is mainly composed of three primary colors: yellow, magenta and cyan, which show the ever-changing colors in the picture, while the black version only aggravates the dark tone and plays a skeleton role.

In terms of color rendering performance, among the four colors of yellow, magenta, cyan and black, yellow has the weakest visual perception, followed by magenta and cyan, and black has the strongest visual perception. Because people's eyes are particularly sensitive to the dot angle of 45, they feel worse about the dot angle of 0 or 90, and the dot angle of15 or 75 is normal for human eyes.
