1) Lithographic printing process of tinplate cans:The biggest feature of lithographic printing is that the printed pattern (the part that adheres to the ink) and the non-printed pattern are on the same plane. Lithographic printing is to print the ink on the rubber cylinder, and then from the pressure cylinder to the tinplate. Because the printing plate will not directly contact the tinplate ink and will not smudge, it is very suitable for high-quality printing. Even if the tinplate is not smooth, there is a chance to overcome it.
2) The bronzing process of tinplate cans:
After heating the tinplate, the post-processing technology of stamping the pattern on the tinplate through the tin foil is popular and widely used because of its bright visual performance.
3) The letterpress printing process of tinplate cans:
Letterpress printing means that the graphic part of the printing plate is higher than the non-graphic part. The ink on the ink roller can only be transferred to the graphic part of the printing plate, and the non-graphic part has no ink, thus completing the printing of the printed matter. A traditional printing technique that emboss the tinplate after the movable type engraving plate of the tinplate is rolled with ink. The pressure on the tinplate can be adjusted according to the needs, forming a rather deep three-dimensional impression.
4) Inkless embossing process of tinplate cans:
The tinplate does not need to be heated, tin foil, and ink-free; it is a processing technology that is directly imprinted on the tinplate with pressure, which is suitable for presenting the original texture of the tinplate or expressing it in a minimalist style.
5) UV printing process of tinplate cans:
It is printed by special ink that dries when exposed to UV light. It is suitable for tinplates that are not easy to dry, or other flat materials such as aluminum products and wood boards.
6) Screen printing process of tinplate cans:
Screen printing is a method of hollowing out the print on the printing plate and allowing the ink to transfer through the mesh. When the substrate is made of tinplate, aluminum plate, plastic and other materials, or curved surfaces such as boxes, cans, or special printing needs such as floating surface effects, screen printing is mostly used.
7) Lithographic printing process of tinplate cans:
Lithographic printing is a relatively mature printing process at present. It is a fast and stable mass printing technology for mass printing tinplate cans. It is a very good and economical choice in the case of a large number of printings.
8) Screen printing process of tinplate cans:
Screen printing is a traditional process of printing with a screen made of nylon thread. In metal printing, only one color or several colors can be used for registration printing. Because it is a semi-manual production, if there are overlapping colors The situation is not suitable for productions with high-precision requirements.
9) Screen printing process of tinplate cans
For screen printing on the surface of tinplate cans, the surface must be pre-treated. The pretreatment process of the surface of tinplate cans is also called pre-press processing. There are many ways to pre-treat the surface of tinplate cans, such as degreasing, polishing, wire drawing, oxidation, sand surface treatment, painting and so on. These processes can be used individually or in combination according to the different requirements of the product and the underlying material to achieve the desired effect.
