Description

Myopia-preventing ink printing process

Technical Field

The invention relates to the technical field of printing, in particular to a myopia-preventing ink printing process.

Background

Paper is the most common article in our daily life, and is in contact with paper when reading books and newspapers, or writing and drawing. Paper is also not available in industrial, agricultural and defense industry. Today, it is simply unthinkable without paper. Paper is a powerful tool and material in communicating ideas, propagating culture, developing scientific technology and production. Reviewing the history, the important substance is invented by people of ancient Chinese laborers. The paper making technology, compass, gunpowder and printing technology are also called as four inventions of ancient Chinese science and technology, and are excellent contributions of Chinese people to the development of world scientific culture.

Paper making is an important invention for ancient Chinese workers. The parts have two forms of mechanism and manual operation. The mechanism is continuously carried out on a paper machine, paper pulp suitable for paper quality is diluted to certain concentration by water, and is primarily dewatered on a net part of the paper machine to form wet paper sheets, and the wet paper sheets are pressed and dewatered and then dried to form paper, wherein the paper is a sheet-shaped fiber product used for writing, printing, drawing or packaging and the like. The plant fiber pulp is produced with water suspension of plant fiber, and through the combination of crossing on net, initial dewatering, compression and stoving.

The existing myopia-preventing printing is to print transverse and longitudinal coatings on paper generally, the coatings are single, and ink is easy to fade. Accordingly, one skilled in the art provides an anti-myopia ink printing process to solve the problems set forth in the background above.

5) and ink mixing: mixing dye, tannic acid, gallic acid, ferrous sulfate, stabilizer, corrosion inhibitor, antiseptic, wetting agent and solvent sufficiently to prepare ink;

6) and confirming information before printing: determining the distribution of ink color, the size of ink amount, the presetting of a water supply system, the printing speed and the size of a gauge;

7) and printing: printing a finished product by a printer, wherein the ink line pattern layer is a crossed oblique line to form a triangular structure, the line width of the adjacent parallel oblique lines is 0.1-1.0 mm, and the distance between the crossed oblique lines is consistent;

8) and binding: and binding the printed paper sheets.

Compared with the prior art, the invention has the beneficial effects that:

1. in the invention, tannic acid, gallic acid and ferrous sulfate are combined with each other to generate ferrous tannic acid and ferrous gallate, and the ferrous tannic acid and the ferrous gallate are oxidized to become insoluble high-valence iron, namely ferric tannate and ferric gallate, so that the water resistance and the blackening property are enhanced, and the ink is water-resistant, black and lasting in color.

2. In the invention, the triangular graphic coating is printed on the original paper, which can stimulate the nervous system, cerebral cortex and retina tissue in eyes of a human body, attract the attention of students, prevent the eyes from being always in a focusing state and prevent the blood pressure of the eyes from being in a high state, reduce the fatigue of the eyes and further achieve the effect of protecting the eyes.
