Problems solved by technology

In recent years, although photo-grade inkjet printing paper (commonly known as digital photo paper) has been introduced on the market, it is limited to two types of high-gloss and matt paper. Double offset paper, due to the material, particle size and production method used in the ink-absorbing layer of the high-gloss paper, the gloss of the high-gloss paper produced is too high, the printed image is too bright, the color is not natural enough, and the image is not realistic enough ; and the surface of the ink-absorbing layer of matt paper is too thick, causing light to scatter towards the surroundings, the gloss is poor, and the image is dull. These two kinds of paper do not have the effect of coated paper, and the printing consumption is the largest in the world and the effect is the best. Good ones are coated papers. However, there is no ink-jet printing paper with this copper plate effect in the domestic market at present, and the demand for this printing paper is increasingly strong in the market. For this reason, the inventor has been continuously working on it for many years Research and exploration, and have achieved the following results

Abstract

The invention is concerned with the mercerizative inking printing paper, especially the inking printing paper with art printing paper effect, the characteristics is: adds nanometer grade silicon dioxide that the grain diameter is 5nm to 30nm and the micron grade silicon dioxide that the grain diameter is 1um to 15um, produces the mercerizative inking printing paper that the printing effect is the artprinting paper effect and precedes highlight printing paper and sub-photochromic printing paper by assorting soften calendering dressing technics and adjusting the proportion of the nanometer grade and micron grade silicon dioxide.

Description

technical field [0001] The invention relates to an ink-jet printing paper and a manufacturing method thereof, in particular to a photo-grade mercerized ink-jet printing paper. Background technique [0002] At present, all design works of printing factories and advertising companies need to go through the process of trial printing and printing samples, that is, artwork works need to go through the production of backing paper→plate making→printing, often for one or two samples, it is necessary to complete a whole set of procedures, Its unit cost is dozens or hundreds of times that of the final product. In recent years, although photo-grade inkjet printing paper (commonly known as digital photo paper) has been introduced on the market, it is limited to two types of high-gloss and matt paper. Double offset paper, due to the material, particle size and production method used in the ink-absorbing layer of the high-gloss paper, the gloss of the high-gloss paper produced is too hig...
