Abstract

The invention discloses a UV offset printing frosted ink, and a preparation method thereof. the UV offset printing frosted ink is composed of, by weight, 40 to 70 parts of a high molecular resin binder, 15 to 30 parts of wax powder, 10 to 30 parts of an active diluents, 5 to 10 parts of a photoinitiator, and 1 to 5 parts of a dispersant. The UV offset printing frosted ink contains no volatile solvent; the VOC content is capable of satisfying requirements in tobacco industry environmental protection standards; screen printing steps are reduced; production efficiency is increased; production cost is reduced; printing printability is excellent; and excellent offset printing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a UV offset printing ink which is printed on tobacco packaging and has a matte effect and a preparation method thereof. Background technique [0002] At present, the matte effect has been widely used in UV screen printing inks, but it cannot be effectively applied in UV offset printing inks due to many limitations of printing technology and printing equipment. UV offset printing ink has saturated ink color, bright printing color, high printing efficiency, non-toxic and environmental protection. It is an environmentally friendly ink developed vigorously in my country in recent years. It is widely used in cigarette packs, wine boxes, gift boxes and other exquisite printed products. field. [0003] At present, the matte effect of cigarette pack printing generally adopts to print a layer of UV offset printing ink first, and then print UV silk screen matte ink to achieve the des...
