In addition to a certain degree of water resistance, tinplate printing color inks also need their special requirements.

In order to improve the adhesion of the printing ink, the tinplate needs to be whitened before printing. White is the primary color of all pictures, with high brightness. After adding other high-energy hues, the brightness of each hue can be increased to form a color gradation.

Tinplate printing belongs to the category of metal printing in special printing. It is named after tinplate as the substrate and is a kind of special printing. Tin plate printing has its particularity in printing process, printing materials and equipment structure.

In order to further implement the continuity of efficiency management incentives and create a production atmosphere of “you catch up with me” for each team, on September 3, the leaders of the factory, Mr. Wu and Mr Chen, commended the outstanding team in August and awarded bonus for the outstanding team staff in August.

The coating on the inner surface of the can is to use a roller coater to print a suitable coating on the smooth surface of the tinplate into a uniform and controllable thickness before the tinplate is cut into a can body blank. The coating machine can independently carry out coating operations through its own feeding device, or it can be matched with the iron printing machine to form a printing coating line.

tinplate printing ink has properties such as impact resistance, strong adhesion, heat resistance, light resistance, and good drying properties

In addition to the printing ability of normal printing inks, tinplate printing inks also have properties such as impact resistance, strong adhesion, and high temperature resistance

The composition of tinplate printing ink is similar to ordinary ink. It is mainly composed of pigments, binders, fillers and auxiliary agents. However, because the surface of tinplate is smooth and its absorption is poor, it must be different from ordinary offset printing inks. In addition to the printing ability of general offset printing inks, tinplate printing inks also have properties such as impact resistance, strong adhesion, heat resistance, light resistance, and cooking resistance.

In tinplate printing, in order to improve the adaptability of post-printing and improve the gloss of the appearance and text of tinplate products, the printing ink should be glazed before the printing ink is completely dried to form a uniform and smooth coating film to avoid bleeding. . Coating varnish can not only improve the gloss, but also enhance the flexibility, impact strength, abrasion resistance and adhesion of the surface of the ink layer. In addition, the coating film formed after the varnish is cured at high temperature isolates the ink coating from the outside world and protects tinplate products from physical and chemical substances.

Coatings are mainly composed of film-forming substances, pigments, driers, auxiliaries, solvents, etc., and can be divided into three types of coatings: inner coating, outer coating and varnish from the coating method and function. It protects the ink layer and increases the brightness of the image to make the product have a good metallic color. At the same time, coatings such as food cans can effectively prevent the contents from being chemically and biologically contaminated, reduce the possibility of leaking the cans, protect the original flavor and color of food, extend the storage time, and make the contents easy to pour out of the containers.
