Description
Technical Field
The utility model relates to the field of package printing, in particular to mirror silver paper.
Background
At present, most of high-grade cigarettes and cosmetic packaging printed matters in the market are printed by using silver paperboard or silver coated paper with strong metal sense as a printing stock, so that the attractiveness and grade of the printed matters are improved, and meanwhile, the packaged products are gorgeous and noble.
The traditional silver paperboard or silver coated paper is paper formed by loading aluminum materials on the surface of a paper base in a vacuum state in a direct composite aluminum spraying or transfer printing mode, and the paper has the characteristics of good smoothness, high smoothness, strong metallic feeling, bright appearance and the like, so that a printed product has strong visual impact, and the surface mirror effect of the paper can well improve the packaging grade of the product. The mirror silver paper of the traditional technology has the following defects although the overall grade is higher:
firstly, the value of most aluminum layers is wasted: in order to show the effect layering sense of the packaging printed matter, the aluminum layer which is required to show the metal sense is usually only a small part, most of the aluminum layer is covered by the thick ink layer, the value of most of the aluminum layer is wasted, and the value of aluminum serving as a metal material is higher.
Secondly, because the silver paperboard or silver coated paper needs to be processed for the second time on the paper base in the manufacturing process, the traditional silver paper has high manufacturing cost (about twice the price of the common white paperboard), and simultaneously, a large amount of energy consumption is brought in the manufacturing process, so that the requirements of future international environmental protection development are not met.
Thirdly, printing adaptability is poor. The traditional silver paperboard or silver coated paper has poor printing ink absorption and drying property due to the surface of the metal aluminum layer, and various printing quality problems such as poor drying and the like are easily generated.

The utility model has at least one of the following beneficial effects:
1) The cost is reduced. The printing of the whole effect of the mirror surface silver can be independently carried out on the part of the paper which is required to show the metallic luster, and the part of the excessive aluminum layer of the original traditional silver paperboard or silver coated paper is not required to be covered by white ink.
2) The production and manufacturing cost is reduced, the energy is saved, the consumption is reduced, and the production cost of each small printed matter can be expected to be saved by 0.03 yuan.
3) The printing adaptability is good. The online gravure high-speed production can avoid the printing quality problems of explosion, falling off and the like of the traditional silver paperboard aluminum layer, and the dot reduction is also superior to that of the common silver paperboard.
4) The utility model can be realized by a single paper gravure mode or an online gravure mode, and the universality of printing production is excellent. If the on-line gravure printing mode is selected, the printing, refraction, concave-convex, indentation, rolling cutting (slitting) and other procedures can be synchronously performed in linkage with the original printing equipment in the production process, so that the production efficiency is greatly improved.
5) Because the silver ink layer is not a single metal aluminum foil of the traditional silver paperboard, but a mixed carrier of resin and metal silver ink, the surface resin of the silver ink layer has better affinity and permeability with printing ink, so that the adhesive force and the drying rate of the ink can be improved, and various printing quality problems such as poor drying and the like are solved.
