The basic elements that affect the printing quality of tin coating steel boxes are as follows:
1. The tin on the surface of the tin coating steel raw material is uneven, which will cause the color of the tin coating steel printing to appear different shades, and will also cause uneven corrosion resistance, which will have a certain impact on the use value of the product. Therefore, electrolytic tin plated steel with poor tin plating will directly affect product quality.
2. Exposure will have a certain impact on quality. In the process of printing the PS plate, the distance between the intensity of the light source and the plate material, and the intensity of the light source will have a greater impact on the electrolytic tin plated steel printed pattern.
3. During electrolytic tin plated steel printing, the dots are prone to appear empty, especially the dots in the high-gloss area. Therefore, the viscosity of the printing ink is higher than that of the printing paper ink, and the fluidity of the printing ink is less than that of the printing ink. The tinning metal sheet does not absorb water and will not penetrate, so the amount of water supply should be slightly
