Abstract

The invention provides an environment-friendly energy-saving CTP (computer to plate) lithographic printing material, and relates to the field of printing materials. The environment-friendly energy-saving CTP lithographic printing material is prepared by the following steps: S1, preparing a plate base; S2, preparing an imaging solution; S3, preparing an auxiliary agent; S4, mixing and stirring theprepared imaging solution and the auxiliary agent, then adding a bacteriostatic agent and a tackifier into a mixed solution, and uniformly mixing to obtain a coating solution; S5, immediately using the prepared mixed solution, placing the coating solution on the upper surface of the plate base, injecting into a mold, fixing the mold, and then slowly injecting the coating solution into the mold, wherein the thickness of the coating solution is controlled to be 1-1.5 g / m < 2 >; and S6, stamping the mold by using a stamping machine, and introducing natural wind into the mold in the stamping process. Through a reasonable manufacturing process of a CTP printing plate material, the purpose of environmental protection can be achieved in the production process of the CTP printing plate material, and the production rate can be increased, so that the yield requirement and the use requirement of a product are met.

Description

technical field [0001] The invention relates to the technical field of printing materials, in particular to an environment-friendly and energy-saving CTP lithographic printing material. Background technique [0002] The CTP printing plate is an aluminum substrate. There are many types of CTP printing plates, which can generally be divided into heat-sensitive type, silver salt type, photopolymerization type and treatment-free type. The CTP printing plate is controlled by a computer, and then through the computer The control of laser scanning seedling imaging has very high requirements on the appearance of CTP plates when used, otherwise it will lead to later use processes. [0003] At present, CTP printing plates have been widely used as environmentally friendly materials. With the increase in usage, the production requirements for CTP printing plates are also increasing. However, in the traditional production process, environmental protection CTP printing plates are required...
