Preparation process of color ink-jet printing photographic paper

Abstract

The invention discloses a preparation process of a color ink-jet printing photographic paper. The process includes the steps of: (1) photographic paper surface treatment, (2) ink absorption layer preparation, and (3) gloss layer preparation. The invention perform reasonable optimization treatment on the existing printing photographic paper preparation technology, eliminates the prime paint coatingprocedure in the original technology, lowers the process complexity, and reduces adding of chemical paints. The preparation process provided by the invention is conducive to lowering the processing cost and reducing the paper thickness, and under the cooperation of the steps together, and the finally prepared printing photographic paper has enhanced ink absorption, glossiness, light resistance, folding resistance and the like, and good comprehensive usage quality, thus having substantial market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of printing photo paper manufacturing, and in particular relates to a preparation process of color inkjet printing photo paper. Background technique [0002] Inkjet printing has the advantages of easy colorization and digital control, and is favored by users who pursue personal colors. With the increase in the number of domestic inkjet printers, the demand for high-quality coated inkjet printing paper has increased. Most of the color inkjet printing photo papers on the market in our country are mainly imported from abroad, and the existing domestic production and theoretical research are relatively poor. The production process of the existing color inkjet printing photo paper is mostly: first coat a layer of primer on the surface of the photo paper, then coat a layer of ink-absorbing layer coating on the primer coating, and finally coat the ink-absorbing layer coating on the ink-absorbing layer coating.

Problems solved by technology

[0002] Inkjet printing has the advantages of easy colorization and digital control, and is favored by users who pursue personal colors. With the increase in the number of domestic inkjet printers, the demand for high-quality coated inkjet printing paper has increased. At present, the color inkjet printing photo paper on the market in our country is mainly imported from abroad, and the existing domestic production and theoretical research are relatively poor.

The production process of the existing color inkjet printing photo paper is mostly: first coat a layer of primer on the surface of the photo paper, then coat a layer of ink-absorbing layer coating on the primer coating, and finally coat the ink-absorbing layer coating on the ink-absorbing layer coating. A layer of glossy coating, wherein the primer is mainly to enhance the fixed adsorption effect of the ink-absorbing layer coating on the photo paper substrate; Color brightness, clarity, saturation, detail level and color reproduction, etc.) are closely related, and the important factor affecting the quality of the ink-absorbing layer coating is the absorption filler in the coating. At present, nano-alumina and nano-silicon dioxide are mostly used as Absorbing fillers, but most of the existing nano-fillers have problems such as easy aggregation and uneven dispersion, which in turn affect the dispersion uniformity and absorption stability of the ink, and most of the existing research on nano-fillers is to improve its ink absorption. Ink absorption and gloss performance are in a trade-off relationship in the traditional sense, and it is rare to see a method that can effectively enhance the above-mentioned comprehensive quality; the gloss layer coating is mainly to enhance the color gloss of photo paper, etc.

It can be seen that the processing technology of the existing photo paper is relatively complicated, and there are many types of coatings used, which is not conducive to the reduction of processing costs
