Background
The printing plate is a printing image-text carrier for transferring ink to printing stock, and can be divided into four types of relief printing plate, intaglio printing plate, lithographic printing plate and porous printing plate. Among them, lithographic printing, also called offset printing, often uses a printing plate composed of two layers arranged one above the other, and forms a printing area and a non-printing area on the surface of the printing plate by laser patterning by energy incident on picture information.
Currently, the offset printing method generally employs the following printing method: a matte concave-convex part is made on the surface of an aluminum plate material, a printing plate is formed by forming a line part and a non-line part on the concave-convex part, an inking roller is used for inking a printing plate cylinder, and then ink on a printing plate surface is transferred to a printed matter between pressing cylinders through a transfer cylinder for printing.
In addition, the waterless offset printing method, in which a printing plate is formed and printed by using a non-image line portion made of a silicone rubber having a property of repelling ink instead of water, is also a printing method commonly used in the offset printing method. In this waterless offset printing process, a silicone rubber is adhered to a film, and the silicone rubber is exposed and exposed on a mask and a negative film, so that the portion where the silicone rubber is peeled off becomes an ink-adhered line-defining portion, and the portion where the silicone rubber remains becomes a non-line-defining portion.
However, the reliability of the metal layer material of the offset printing plate in the market is generally low, the temperature is high, the pasting failure can occur, and the dirt removal of the offset printing plate after the offset printing plate is dirty is difficult.
Therefore, it is an urgent problem to provide a heat and wear resistant flexographic printing plate having a long service life.
