At present, the matt oil of the conventional UV offset printing ink fountain loses the matte effect in the area where the printed matter has the matte oil of the UV offset printing ink fountain after printing UV coating varnish, and the printed matter can only be returned to the printing machine for separate printing after UV coating and varnish UV offset printing ink fountain dull oil has brought great troubles to ink manufacturers and printing manufacturers. At present, there is an urgent need for printing conventional UV coating varnish or conventional UV reverse varnish. UV offset printing ink fountain matte oil to maintain matte effect

Abstract
The invention discloses UV offset printing ink fountain matte varnish as well as a preparation method and application thereof, and relates to the technical field of UV offset printing ink. The UV offset printing ink fountain matte varnish comprises the following components in parts by weight: 40-50 parts of a polymerizable oligomer, 20-30 parts of a reactive diluent, 10-20 parts of matting powder, 5-15 parts of a light initiator and 1-10 parts of an additive, the polymerizable oligomer is prepared from rosin modified acrylic resin and urethane acrylate; the reactive diluent comprises at least one of an acrylate bifunctional monomer and a trifunctional monomer. The components of the ink are selected, so that the ink can be applied to printed matters, and after being covered with UV coating gloss oil or UV reverse gloss oil, the ink can still keep a good matte effect and has good wear resistance, and the durability of the matte effect can be ensured.
Description
technical field [0001] The invention relates to the technical field of UV offset printing inks, in particular to a UV offset printing ink fountain dummy oil and a preparation method and application thereof. Background technique [0002] The main function of the ink fountain matte printing process is to protect the surface of the printed matter from being stained and scratched, and to obtain different printing effects on the printed matter. Matte and bright light can appear on the same page at the same time, increasing the aesthetic feeling and improving the appreciation of the printed matter. value. Ink manufacturers around the world have launched their UV offset printing ink fountain matt oil, because most of the UV offset printing process requires an additional UV coating glazing or UV coating reverse glazing process after ink fountain ink printing. At present, the matt oil of the conventional UV offset printing ink fountain loses the matte effect in the area where the pr...
