Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the examples, so that those skilled in the art can better understand the present invention, but the present invention is not limited to the following examples.

[0028] A method for reducing volatile organic compound residues in gravure printing cigarette packs. In the usual gravure printing process steps, it also includes reducing the depth of the solid plate mesh, adjusting the ink solvent ratio, increasing the drying temperature of each color group during the printing process, and increasing the ventilation. Quantity and the process of post-processing of finished products.

[0029] In the preferred disclosed example of the present invention, the step of reducing the depth of the solid plate's cells is to reduce the plate-making depth of the solid gravure printing from 40 to 60 U by 5 to 6 U.

[0030] In the preferred disclosed example of the present invention, the process of adjusting the ink...

Abstract

The invention belongs to the technical field of environment-friendly printing, and relates to a method capable of reducing volatile organic compound residue, in particular to a method for reducing volatile organic compound residue during cigarette packet gravure. According to the method for reducing volatile organic compound residue during cigarette packet gravure, field version ink cell depth reduction, ink solvent ratio adjusting, color cell drying temperature rising in the printing process, exhaust amount increasing and finishing of a finished product are included; through the above procedure treatment, the product can meet the quality need of solvent residue standard in the YQ 69 cigarette strip and box packaging paper safety sanitation need, it can be ensured that a final product is qualified and delivered, the requirement that under the condition that the raw material or process is abnormal, the sanitation safety index exceeds the standard, the finished product delivery has the solution scheme is met, and the promptness of delivery required on the market can be met.

Description

technical field [0001] The invention belongs to the technical field of environmental protection printing, and relates to a method for reducing residues of volatile organic compounds, in particular to a method for reducing residues of volatile organic compounds in gravure printing cigarette packs. Background technique [0002] Gravure printing is a plate-making technique in which an image is engraved from a surface in depressions. Generally speaking, a copper or zinc plate is used as the surface of the engraving, and the recessed part can be etched, engraved, copper engraving or mezzotint metal plate making method, and Collographs can be printed according to the gravure plate. To print a gravure plate, the surface is covered with ink, which is then wiped from the surface with tartham or newspaper, leaving only the depressions. Wet paper is placed on top of the printing plate, and the printing plate and paper are pressed through the printing press, which transfers the ink fro...
