Characteristics of Tin Sheets Lithographic Printing:
Tin Sheets Lithographic Printing belongs to the category of metal printing,is one kind of special printing. Tin Sheets Lithographic Printing has its special features in printing technology, printing materials and printing equipment structure.
1. Due to the special physical and chemical properties of tin sheet and the reprocessing performance of tinplate printed matter, its printing process is greatly different from ordinary offset printing.Tin Sheets Lithographic process is as follows:
Coating before printing-Printing-coating after printed-Processing.
2. Special requirements for printing ink:
(1) Has good adhesion and mechanical properties
Because Tin Sheets Lithographic products are eventually made into food cans, toys, metal photo frames, and barrels and paint cans, they need to be cut, bent, and stretched. Therefore, printing inks are required to have good adhesion to tin sheet and corresponding machinery performance. In order to improve the adhesion of the printing ink, the tin sheet needs to be white-primed before printing.
(2) Requirements for white ink
The tin sheet surface is silver-white (or yellow) with metallic luster. Before printing the color graphics, the surface needs to be printed white. Due to the limitation of the ink covering ability, it usually takes 2-3 times to print white, and its whiteness can reach 75%. Whiteness is an important indicator of the quality of printed tinplate products. Printed white ink has a good binding force with the primer, does not turn yellow after high temperature baking, and does not discolor after high temperature resistance. Applying a primer to tinplate can increase the adhesion to tinplate and have a good combination with white ink.
(3) Requirements for color ink
lithographic printing color inks, in addition to having a certain degree of water resistance, also need their special requirements. As the tinplate surface does not penetrate water and solvents, it needs to be baked and dried, so its ink should be heat-curable. The pigment is required to have higher tinting strength and durability. In addition to the basic properties of general offset printing inks, iron printing inks should also have the characteristics of heat resistance, strong ink film adhesion, impact resistance, good rigidity, cooking resistance and light resistance according to the characteristics of printing iron.
(4) Drying process of ink
In the production of tin sheets printed, the drying of the ink is a complicated physical and chemical reaction process. There are many factors that affect drying, so to control the drying speed of the ink and ensure the quality of the product, the physical and chemical mechanism in the ink drying, that is, the factors that affect the drying speed, must be mastered in order to effectively perform the fast iron printing operation.
3. Special structure of printing equipment
Due to the different substrates, the auxiliary structure of the tin sheet printer is also different from the offset printing machine. Because tin sheet is insoluble in water and does not adsorb solvents, the printing ink needs to be baked at high temperature to cure the solvent volatile conjunctiva. Iron printing process equipment should be equipped with iron printing drying room. Printed iron automatic line is generally about 52 meters in length, which has the characteristics of precision and hugeness.
