Abstract

The invention belongs to the technical field of inkjet printing, and in particular relates to a kraft paper natural color high-definition color saturation printing method, comprising the following steps: S100: providing water-based varnish, and adding polyvinylpyrrolidone to the water-based varnish; S200: kraft paper after The paper feeding unit is transported into the pre-printing unit, and the water-based varnish is printed on the kraft paper through the pre-printing unit, so that a water-based varnish layer is formed on the surface of the kraft paper; S300: sending the kraft paper to an inkjet printer In the above step, inkjet printing is performed on the kraft paper by the inkjet printer, and a printing pattern is formed on the water-based varnish layer; S400: Send the inkjet printed kraft paper to a delivery unit for recycling. The method of the invention can enhance the high optical density and color saturation of ink printing, and the printing surface is smoother; secondly, the initial investment is less, and the later maintenance cost is lower; in addition, the existence of the water-based varnish layer increases the waterproof ability of the kraft paper.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to a kraft paper natural color high-definition color saturation printing method. Background technique [0002] At present, the ink used for kraft paper inkjet printing mostly adopts dye type, because the dye exists in the state of a single molecule in the ink, the dye type ink has the advantages of convenient preparation, low cost, complete color spectrum, and is not easy to block the nozzle, but the dye ink The stability of dye ink is poor, and dye ink is very picky about printing media and materials, and often requires special media support to achieve printed products with high color saturation. For dark porous materials such as kraft paper, the ink will quickly penetrate into the pores of the substrate, resulting in a low optical density of the surface, making the color dark and unsaturated. Although white ink has been used on the market to increase color sat...
