A printed matter with special functional properties

Abstract

The invention discloses a printed matter with special functional properties. The printed matter is added with substances with special functional properties in the fountain solution used in the printing process. The invention has the advantages of simple operation, economical application, adding ingredients with special functionalities into the fountain solution, convenient formula adjustment, low production cost, rich varieties, and obtaining a health-care function, color-changing function, and improved reading interest. kinds of prints.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional printing, in particular to a printed matter with special functional characteristics. Background technique [0002] Printing is one of the four great inventions in ancient my country. Long before Cai Lun invented paper in the first year of the Eastern Han Dynasty (105), at the end of the Spring and Autumn Period and the Warring States Period, the stencil printing technique of hollow-out printing with negative patterns on silk fabrics had been invented. At the end of the Sui Dynasty and the beginning of the Tang Dynasty, that is, in the early 7th century AD, woodblock printing was invented. In the Northern Song Dynasty, Bi Sheng, a printing master, adopted movable type printing (1041), creating a new era of movable type printing on paper in the printing history of our country. In the following nearly 1,000 years of development, printing has experienced technological changes such as gravure ...

Problems solved by technology

[0003] In order to improve the readability and interest of printed matter, new functional printed matter is gradually produced. For example, patent application 200810034754.3 proposes a printing process for making perfume paper, which is mainly achieved by adding essence to ink during the printing process. However, this method needs to intervene from the production source of ink and paper in the preparation, the development and production cycle is long, the formula is complicated, it is not easy to adjust at any time, the production cost is high, the variety is not rich enough, the one-time formula, the output is huge, and cannot satisfy the niche. new needs of social consumption such as globalization, diversification, and rapidity; patent application 200610111654.7 proposes another method for making long-lasting fragrance printed matter, which mainly prints or coats fragrances on the surface of printed matter by UV curing, and light-cures to add fragrance When the agent is exposed to light, it undergoes a polymerization reaction, and it can be cured on the surface of the printed matter in an instant to form a printed matter with a lasting fragrance. The cured printed matter forms a colorless and transparent film on the surface, which will not affect the quality of the printed matter

This method must ensure sufficient coating amount and good powder spraying measures, otherwise, there will be failures such as smudging and sticking of printed products caused by wet pressing and drying in general oily glazing, and the printed image must have a heavier tone, and the printed image The area must have a large area so that the surface of the paper can be printed with a light-curable flavoring agent that is sufficient to exert a fragrance effect. In addition, after the photo-curing flavoring agent is mixed into the printing ink, it will affect the adaptability of printing, reduce the printing quality, and easily occur. printing failure
