Manufacturing method of high-level colour laser printing paper

Abstract

The invention discloses a manufacturing method of high-level colour laser printing paper. According to the manufacturing method, softwood pulp and hardwood pulp are used, and the processing steps of beating, blending, auxiliary material adding, papermaking of wet paper sheets, front drying, sizing, after drying, press polishing and finishing are respectively performed, wherein the ratio of the softwood pulp to hardwood pulp is (5-20):(80-95) in percentage by weight; after the pulp is beaten, the freeness of the softwood pulp is 280-320 ml and the freeness of the hardwood pulp is 380-420 ml; during surface sizing, an enzyme prepared on site is converted into starch; the high-level color laser printing paper has the definite quantity of 100g/m<2>, and the main indexes are as follows: moisture accounts for 4.5 to 5.5 percent, the tensile strength is equal to or greater than 5.0 KN/m, the stiffness is 150 mN, the bulk is larger than or equal to 1.15 cm<3>/g, the ash content is less than or equal to 20 percent, the smoothness average value is larger than or equal to 70 S, and the surface absorption weight is smaller than 35 g/m<2>. The manufacturing method provided by the invention has the advantages that the product quality stiffness is high, the dimensional stability is excellent, the passing-machine performance is excellent, the paper cleanliness is high, the smoothness is high, the transfer printing capability is high, the color saturation of a printed product is good, and images are vivid.

Description

technical field [0001] The invention relates to a method for manufacturing high-grade color laser printing paper, belonging to the technical field of papermaking. Background technique [0002] Color laser printing paper is the printing paper used for color laser printers. It is different from ordinary monochrome laser printing. This printing method uses black, yellow, magenta, and cyan four-color printing, and relies on the toner cartridge to sensitize four times. The toner is transferred to the transfer toner cartridge, and the transfer toner cartridge transfers the graphics to the printing paper to achieve the result of outputting color graphics. [0003] When the existing traditional laser printing paper is used for color printing, there is a problem that the degree of color reproduction is not high, especially when printing photo files, the color expression is weak, because high-end color laser printer paper needs to be used to produce high-end effects Drawings, bidding...

AI Technical Summary

Problems solved by technology

[0003]When the existing traditional laser printing paper is used for color printing, there is a problem that the degree of color reproduction is not high, especially when printing photo files, the color expression is weak , As the high-end color laser printer paper needs to be used to make high-end renderings, bidding documents, and exquisite brochures, traditional laser printing paper cannot meet the requirements

At the same time, high-end color laser printers have higher requirements on paper performance, and traditional laser printing paper is prone to paper jams during use

In addition, the paper used for high-end color laser printers must have little wear on the printing equipment, and traditional laser printing paper cannot meet the requirements
