In my perception, round metal tin cans are a rigid, well-sealed, textured and atmospheric looking packaging product. Previously, a customer asked me, "Why is it called tin cans?" In fact, tinplate is a can-making material, also known as tin-plated iron, corrosion-resistant, can be very good to avoid tin cans will rust, extend the service life and keep the appearance of beautiful.   customized metal tin cans are generally printed. Printing not only allows tin cans to increase the sense of color but also will make your product packaging in the market dazzling, at first glance to attract the consumer's eye. The tin can printing process is quite complex and demanding, so today I would like to introduce to you a brief description of its printing process.   First of all, custom printed tin cans printing color ink is to possess a certain degree of water resistance, in addition to other special requirements. As the tin surface does not permeate water and solvent, the need to dry after baking, so its ink should be heat-curing type. The pigment coloring power and durability requirements are high, printing iron ink in addition to the basic performance of general offset ink, according to the characteristics of the printed iron should also feature heat resistance, strong ink film adhesion, impact resistance, good hardness, resistance to cooking and light resistance.   In the production of printing tinplate, the drying of ink is a complex physicochemical reaction process. Many factors affect the drying, so to control the drying speed of the ink, to ensure product quality, we must master the drying of ink in the physical and chemical mechanism that affects the drying speed of the factors, in order to effectively carry out the speed of printing iron work. The drying speed of ink has become the main content of ink drying, then, what is the harm of ink drying too fast?   1.Which can reduce the normal transfer performance of the ink and affect the normal production. 2.It can cause the print to be false, the ink color is light, the printing plate, ink roller surface ink dry knot, so that the transfer of the next ink is blocked. 3.You can make the printing plate graphics dry knot layer to expand outward.
