The weight percentages are: ethyl acetate 50%-70%, ethanol 30%-50%; (3) the alcohol-soluble ink to be environmentally friendly After the solid-liquid mixed state, the object to be printed is pressed down into the water according to the position of the calligraphy and painting pattern floating on the horizontal surface; the purpose is to provide a simple process, no pollution to the environment, and can be on the surface of complex and varied products. Printing and calligraphy pictures alcohol-soluble ink coating film printing process and application. Sovereign Items 1. Alcohol-soluble ink coating film printing process, which is characterized by the following steps: (1) using a gravure printing process, using environmentally friendly alcohol-soluble inks to print calligraphy and painting patterns on instant polyvinyl alcohol films; (2) steps (1) The instant polyvinyl alcohol film obtained is laid on the surface of the water with the printed pattern facing upwards. After the instant polyvinyl alcohol film is softened and dissolved, the activated reducing agent is evenly sprayed on the instant polyvinyl alcohol. On the film, the activated reducing agent is composed of ethyl acetate and ethanol in percentages by weight: ethyl acetate 50%-70%, ethanol 30%-50%; (3) the alcohol-soluble ink to be environmentally friendly becomes a solid-liquid mixture. After the state, the object to be printed is pressed down into the water according to the position of the calligraphy and painting pattern floating on the horizontal surface.
