Small Knowledge Of Tin Can Printing

In my understanding, a tin can is a packaging product with strong rigidity, good sealing, good texture, and an atmospheric appearance. In Tiktok before, a partner asked me, "Why is tinplate?" In fact, tinplate is a can making material, also known as tinned iron. It is corrosion resistant, which can well avoid rust, extend the service life and maintain a beautiful appearance.
Tin cans are usually printed. Printing not only adds color to the cans, but also makes your product packaging stand out in the market, attracting consumers' attention at first glance. The printing process of tin cans is quite complex and requires high requirements. Today, I will briefly introduce its printing process to you.
Firstly, the color ink used for tin can printing has certain water resistance, and there are other special requirements. Due to the impermeability of moisture and solvents on the surface of tinplate, it needs to be baked and dried, so its ink should be heat cured. The requirements for the coloring power and durability of pigments are high. In addition to the basic properties of general offset printing inks, iron printing inks should also have characteristics such as heat resistance, strong ink film adhesion, impact resistance, good hardness, cooking resistance, and light resistance according to the characteristics of iron printing.
In the production of printing iron, the drying of ink is a complex physicochemical reaction process. There are many factors that affect drying, so in order to control the drying speed of ink and ensure product quality, it is necessary to grasp the physical and chemical mechanisms in ink drying, namely the various factors that affect the drying speed, in order to effectively carry out fast iron printing operations. The drying speed of ink has become the main content of ink drying, so what are the hazards of ink drying too fast?
1. It can reduce the normal transmission performance of ink and affect the normal production process;
2. It can cause the imprint to become blurry, the ink color to fade, and the surface of the printing plate and ink roller to become dry, hindering the transfer of ink;
3. It can expand the dry layer of the printing plate image and text outward.
