Description

Technical Field

[0001] The utility model relates to the technical field of rubber surface printing, in particular to a rubber surface printing device. Background Art

[0002] Offset printing is a printing method that transfers the ink on the rubber surface to the paper surface through a roller-type rubber stamp. Since the rubber surface is flat and has no concave patterns, the patterns and patterns on the printed paper are also flat and have no three-dimensional effect. Offset printing is mainly based on the immiscible characteristics of oil and water. During the printing process, the selective adsorption of ink and water on the printing plate is used to make the image part adhere to ink and the non-image part adhere to water, thereby realizing the printing of the image. Specifically, the printing plate of offset printing usually consists of an oleophilic image part and a hydrophilic non-image part. Before printing, the printing plate will undergo a series of treatments so that the image part has the ability to absorb ink, while the non-image part has the ability to absorb water. In this way, on the printing press, when the printing plate comes into contact with ink and water, the ink will selectively adhere to the image part, while the water will selectively adhere to the non-image part. Subsequently, the printing plate comes into contact with the paper, and through the action of pressure, the ink of the image part is transferred to the paper to form the desired printed product.
