Abstract

The invention provides an environment-friendly special printing technology for reducing waste water, and relates to the technical field of printing. The environment-friendly special printing technology comprises the following steps of preparation of a degreasing agent, printing of a plate material, cleaning of printing ink, degreasing cleaning and water washing. The environment-friendly special printing technology overcomes the defects in the prior art, the degreasing efficiency of the degreasing agent is greatly improved, so that the cleaning efficiency of the plate material is improved, theplate material is subjected to degreasing cleaning and water washing in sequence in a spraying mode, not only can the plate material be cleaned comprehensively, but also the use of a degreasing agentand water can be effectively reduced, so that the generation of waste water is reduced, the water resources are saved, and the environment-friendly and energy-saving effects are achieved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an environmentally friendly special printing process for reducing waste water generation. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. [0003] During the printing process of various printed products, a large amount of printing wastewater will be generated. For example, plate printing, because there will be residues such as ink and dust during the printing process, these residues will affect the printing effect of the plate, and then affect the quality of the printed product. Therefore, the plate needs to be rinsed after printing to ...
