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.

Tinplate tea can printing has special requirements for inks,especial for the white printing ink for the tea can and food can,tinplate tea can printing ink has good adhesion and corresponding mechanical functions.

The plate making method of tinplate printing is the same as that of paper printing, but there are special requirements for the characteristics of printing tinplate.

The inspection of finished printed tinplate products is divided into two types: conventional physical and chemical inspection and special requirements inspection.

Tinplate printing belongs to the category of metal printing,is one kind of special printing. Tinplate printing has its special features in printing technology.

Tinplate has a wide range of applications, from packaging materials for food and beverages to grease cans, chemical cans and other miscellaneous cans. The advantages and characteristics of tinplate provide good protection of the contents in physical and chemical properties.
