In light led as UV-curable offset ink

The present invention discloses an LED light source of UV-curable offset ink, as parts by weight: 20 to 30 parts of the pigment, the radiation curable resin 55 to 75 parts, 1 to 7 parts photoinitiator, 0 to 3 parts of wax, 0.1 to 5 parts reactive diluents, 0.5 to 4 parts adjuvant. UV-LED light-curing inks according to the present invention has the following characteristics: The ink for offset printing, curing energy consumed when only about one quarter of the ordinary ultraviolet lamp, greatly reducing CO2 emissions; etc do not produce ozone. This ink cure speed of 40-200m / min under printing conditions was dried completely, and clear lines. After the curing performance (adhesion, abrasion, chemical resistance, etc.) meet the demand for printing securities.
