Toyo Ink Manufacturing Co., Ltd. of Japan introduced an EB (electron beam) curing ink that does not contain a photoinitiator. The ink can achieve high-speed multi-color printing, compared with the general ink, the pigment concentration is 2.5 times higher, curing without the use of photoinitiator, can rely on electron beam irradiation, instant and the substrate and dry. Rewind after printing, suitable for PET, PP, PE, PS and other thin film printing.
In the past, in the gravure printing of composite flexible packaging materials, in order to reduce the volatilization of organic solvents in gravure inks or other packaging inks, UV curing inks and UV varnish have been advocated. However, since the drying performance of the UV-curable ink restricts the printing efficiency, and the photopolymerization initiator is used in the UV ink, the cost is increased. The EB curing ink introduced by Japan Toyo not only solves the problem of instantaneous drying, but also has a lower cost.
