Abstract

The invention discloses coated paper suitable for a high-speed ink-jet printer and a production method thereof. The coated paper suitable for a high-speed ink-jet printer comprises a base material, wherein one side or both sides of the base material is/are coated with an ink absorption coating, and the ink absorption coating comprises polymer microspheres, inorganic powder filler and pigment ink fixing agent and adhesive for pigment ink. The production method of coated paper comprises the following steps of preparing coating liquid of the ink absorption coating, wherein the coating liquid comprises polymer microspheres, inorganic powder filler and pigment ink fixing agent and adhesive for pigment ink; coating one side or both sides of the base material with the ink absorption coating, wherein the coating weight of the ink absorption coating is 10-30gsm. The coated paper disclosed by the invention is suitable for being directly printed with high-speed ink-jet printing equipment using pigment type ink, high-definition images and texts can be provided, and the printed product has excellent scraping resistance.

Description

[technical field] [0001] The invention relates to coated paper, in particular to a coated paper suitable for high-speed inkjet printing machines and a manufacturing method thereof. [Background technique] [0002] High-speed digital printing machines based on inkjet technology have developed rapidly in the market, and their printing speed can reach a maximum of 200 m / min. The ink used in many inkjet printing machines is water-based ink, and the water content in the ink exceeds 80%, or even exceeds 90%. Due to the high printing speed, how to dry the printed image quickly is a big challenge. In order to achieve high-speed printing, this type of printing machine will set up a high-temperature drying area after the printing area, so that the printed matter can be dried quickly for subsequent operations such as winding, cutting, and packaging. [0003] In printing production, in order to improve the color effect of printed matter, coated paper with a smooth coating on the surfac...
