Problems solved by technology

Because the viscosity of prepolymers in UV inks is generally very high, active diluents need to be added to dilute them, and the diluents used in acrylate compounds have different degrees of skin irritation and toxicity, so they do not meet the needs of environmental protection

Embodiment 1

[0030] A printing sheet is used as the printing base material, and the material of the sheet can be paper, wood or other substrates suitable for surface printing. Follow the steps below to print on both sides:

[0031] (1) Clean the front and back sides of the thin plate to be printed, and then spray a layer of ink spacer on the front and back sides of the thin plate;

[0032] (2) Dry the printing sheet sprayed with ink spacer with hot air to solidify the ink spacer into a film;

[0033] (3) Place the dried printed sheet in a microwave processor for microwave curing;

[0034] (4) Prepare environmentally friendly ink, transfer the microwave-cured printing substrate to the printing equipment, and spray the environmentally friendly ink on the front and back sides of the printing substrate after positioning;

[0035] (5) Place the printed sheet coated with environmentally friendly ink in a hollow drying box for hollow drying treatment to complete double-sided printing.

Abstract

The invention discloses a green double-sided printing method. By using an ink spacer liquid prepared from tripropylene glycol diacrylate, cetearyl ethyl hexanoate, sodium alginate aqueous solution, glycerine, and a dispersant, the After the isolation film is formed on the front and back sides of the printing sheet, it can effectively prevent the printing ink from penetrating between the front and back printing sheets and maintain the stability of the printed pattern. Simultaneously, the present invention has adopted the environmental protection ink that is formulated with styrene-acrylic resin, acetyl tributyl citrate, 2,6-di-tert-butyl-p-cresol, hydroxyethyl cellulose, polyvinyl alcohol, has avoided the dilution in ink The harm caused by harmful ingredients such as chemicals to the human body and the environment. Moreover, microwave curing and other means are adopted in the preparation process of the present invention, so that the ink spacer liquid can be further firmly combined with the printing sheet after drying, so as to maintain the stability of the spacer layer.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a green double-sided printing method. Background technique [0002] Green printing refers to the use of environmentally friendly materials and processes, the printing process produces less pollution, saves resources and energy, and is easy to recycle and recycle printed materials after they are discarded. It can be naturally degraded and has little impact on the ecological environment. Green printing requires coordination with the environment, including the use of environmentally friendly printing materials, a clean printing production process, the safety of printed materials for users, and the recycling and recycling of printed materials. That is to say, the entire life cycle of printed matter from raw material selection, production, use, recycling, etc. should meet environmental protection requirements. [0003] Double-sided printing usually refers to printing patterns or tex...
