Printing process for realizing matte effect through lithography and flexography

The invention relates to a printing process for realizing a matte effect through lithography and flexography and belongs to the field of packaging and printing processes. The traditional offset printing press is generally provided with an online glazing unit with a flexography method; an initially dried or completely dried ink undercoat layer with lower surface tension is printed on a printing stock by using an offset printing process; and then an ink layer, of which the surface tension is 0.004-0.01 N/m larger than that of the undercoat layer, is printed on the undercoat layer by using the flexography method; when flexography ink is printed to the surface of the ink on the undercoat layer, the flexography ink layer is retracted because the surface tension of the flexography ink layer is larger than that of the undercoat layer, so that an obvious matte texture can be obtained after the flexography ink is cured. By controlling the surface tension difference between the undercoat layer and the wet flexography ink, the shrinkage degree of the flexography ink is controlled; and through the adjustments such as inking quantity adjustment and color adjustment, the thickness, color and matte sense of the whole matte effect can be rapidly adjusted.
