Problems solved by technology

[0002] In the existing printing process, the common problem of printing with water-based high-gloss varnish on gray-backed white cardboard is that due to the relatively low price of gray-backed white cardboard, less wood pulp components are used in the paper production process, and some A large part is added with straw pulp or other relatively low-cost things. The paper produced has high water absorption and poor moisture retention. The amount changes rapidly with the humidity in the air, and the air in the paper is relatively more

Embodiment 1

[0012] The invention is a printing process of water-based high-gloss varnish on low-quality paper. The printing process includes reducing the film-forming agent component in water-based high-gloss varnish from 35% by weight to 27%, and reducing the water-based high-gloss varnish to 27%. The particles in the varnish are made into nanoscale, and 1% by weight of water-based wax slurry with a particle size of 3 to 5 microns is added to the water-based high-gloss varnish.

[0013] The preferred technical solution is that the water-based high-gloss varnish is a liquid acrylic resin, and the liquid acrylic resin is mainly composed of a non-film-forming agent, a film-forming agent and a small amount of additives.

[0014] A further preferred technical solution is that the water-based wax slurry is liquid polyethylene and / or polypropylene.

Embodiment 2

[0016] The invention is a printing process of water-based high-gloss varnish on low-quality paper. The printing process includes reducing the film-forming agent component in water-based high-gloss varnish from 40% by weight to 32%, and reducing the water-based high-gloss varnish to 32% by weight. The particles in the varnish are made into nanoscale, and 3% by weight of water-based wax slurry with a particle size of 3-5 microns is added to the water-based high-gloss varnish.

[0017] The preferred technical solution is that the water-based high-gloss varnish is a liquid acrylic resin, and the liquid acrylic resin is mainly composed of a non-film-forming agent, a film-forming agent and a small amount of additives.

[0018] A further preferred technical solution is that the water-based wax slurry is liquid polyethylene and / or polypropylene.

Embodiment 3

[0020] The invention relates to a printing process of water-based high-gloss varnish on low-quality paper. The printing process includes reducing the film-forming agent component in the water-based high-gloss varnish from 37% to 40% by weight to 29%. The particles in the water-based high-gloss varnish are made into nanoscale, and 2.5% by weight of water-based wax slurry with a particle size of 3 to 5 microns is added to the water-based high-gloss varnish.

[0021] The preferred technical solution is that the water-based high-gloss varnish is a liquid acrylic resin, and the liquid acrylic resin is mainly composed of a non-film-forming agent, a film-forming agent and a small amount of additives.

[0022] A further preferred technical solution is that the water-based wax slurry is liquid polyethylene and / or polypropylene.

Abstract

The invention discloses a printing technology of water-based glazed gloss oil on low-quality paper. The printing technology comprises the following steps: reducing a film-forming agent component in the water-based glazed gloss oil to 27-32% from 35-40%; fabricating particulate matters in the water-based glazed gloss oil into nanoscales; adding water-based wax slurry of which the weight percent is 1-3% and the granularity is 3-5 microns to the water-based glazed gloss oil. The water-based glazed gloss oil is applicable to printing on the low-quality paper by improving the components and the proportions of the water-based glazed gloss oil and adding the water-based wax slurry of which the weight percent is 1-3% and the granularity is 3-5 microns, so that the printed product is smooth and level in surface, and the technical problem that small salient points are easily formed when the water-based glazed gloss oil is printed on the low-quality paper is solved.

Description

technical field [0001] The invention relates to a printing process, in particular to a printing process using water-based high-gloss varnish on low-quality paper. Background technique [0002] In the existing printing process, the common problem of printing with water-based high-gloss varnish on gray-backed white cardboard is that due to the relatively low price of gray-backed white cardboard, less wood pulp components are used in the paper production process, and some A large part is added with straw pulp or other relatively low-cost things. The paper produced has high water absorption and poor moisture retention. The amount changes rapidly with the humidity in the air, and the air in the paper is relatively large. In the printing process, if the product is not multi-color full-page printing, there will be prominent small dots on the surface after the product is printed with varnish, just like goosebumps. If it is full-page multi-color printing, it will generally not appe...
