Abstract

The invention discloses a gravure printing process for a paper packing box, and additionally further discloses a gravure printing device for the paper packing box. The gravure printing process comprises the steps that ink is prepared, and the surface of a printing plate is fully coated with the prepared ink; the printing plate fully coated with the ink is subjected to ink scraping and ink discharging treatment; paper used for the paper packing box is printed through the printing plate subjected to ink scraping treatment; the printed paper is dried; and the paper is coiled. Various materials which can improve viscosity and raw materials with the fragrant smell are added during ink printing, thus the clarity of the ink in the printing process is better, the bad smell does not exist any more,and toxic substance volatilization does not exist as well. The medium-frequency induction heating mode is adopted in the printing process, heating temperature control is more stable, and thus the effect after printing is better; and the working procedures of ink scraping and ink discharging are adopted, thus the situation that an ink scraper carries the ink to be re-dripped on a blank part of thesurface of the printing plate is avoided, and the gravure printing quality is further improved.

Description

technical field [0001] The invention relates to the technical field of packaging box printing, in particular to a paper packaging box gravure printing process and printing equipment thereof. Background technique [0002] Intaglio printing (Intaglio printmaking) is to make the entire surface of the printing plate be covered with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only stays in the cells of the graphic part, and then in the larger Under the action of high pressure, the ink is transferred to the surface of the substrate to obtain printed matter. Gravure printing belongs to direct printing. The graphic part of the printing plate is concave, and the degree of depression varies with the level of the image, and the blank part of the printing plate is raised and on the same plane. [0003] Although the squeegee in the gravure printing equipment for traditional paper packaging boxes can scrape off the ink on the blank...
