[Tinplate surface hardness test]
We know that the strength of the surface strength of a tinplate can be related to the thickness of the material and the hardness of the material used in the can. One factor alone is that it cannot judge the bearing capacity of the tank surface.
Both white porcelain and white ink are made of a white background on the color pattern. Because the tinplate material is essentially different from the paper, the tinplate must be white-finished before printing. The difference between white porcelain and white ink is that white porcelain has no iron permeability, which makes the color pattern more clear, bright and full; while white ink has iron permeability, which can highlight the metal texture and texture.
Four-color printing is the color achieved by CMYK four basic printing color stacking nets. From the printing effect, the network cable is more obvious, the surface is relatively rough and not full enough; the spot color is prepared by the printing ink blending engineer according to the special color color card. Carry out the printing process. From the printing effect, the color of the spot color printing is more full and bright, and from the perspective of printing cost, the spot color printing is higher than the four color printing.
