Problems solved by technology

When using gold cardboard as the substrate to print barcodes, after the white bars are overprinted on the gold cardboard, they will turn yellow under the influence of the hue of the gold cardboard, which will reduce the difference between the white bars and the black bars, resulting in a barcode level that is too low

preparation example Construction

[0046] The invention provides a method for preparing imitation gold cardboard, which uses gravure printing to transfer a gold imitation gravure ink composition to the surface of silver cardboard, and obtains the imitation gold cardboard after drying and curing.

[0047] The present invention uses silver cardboard as a raw material to prepare imitation gold cardboard with the effect of gold cardboard. The silver cardboard is a kind of matte paper, and the present invention does not have any restrictions on its source. Paper will do.

[0048] In the present invention, gravure printing is used to transfer the imitation gold gravure ink composition to the surface of the silver cardboard. The gold imitation gravure ink composition is a gravure ink composition prepared according to the hue of the standard sample, which is consistent with the surface color of the standard sample. The golden-like gravure ink composition provided by the present invention can be the golden-like gravure...

Abstract

The invention provides a preparation method of gold imitated card paper. According to the preparation method provided by the invention, gravure printing is adopted for transferring gold imitated gravure ink composition onto the surface of a silver card paper, and drying and curing are carried out, so that the gold imitated card paper is obtained. When the gold imitated card paper is taken as a printing stock during printing, the gold imitated card paper is not influenced by a printing process, hue of the gold imitated card paper is consistent with the hue of standard sample manuscript gold card paper, stable hue of the gold imitated card paper can be guaranteed, and a printing technology of the gold imitated card paper is simple. The invention also provides a bar code printing method. According to the bar code printing method provided by the invention, the gold imitated gravure ink composition is printed on the surface of the sliver card paper except a region in which a bar code is required to be printed, so that the region in which the bar code is required to be printed can not contain the gold imitated gravure ink composition and is in the colour of the silver card paper; and white gravure ink is overprinted in the region in which the bar code is required to be printed, and sign contrast between black bars is increased, so that the grade standard of the bar code is met.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a preparation method of imitation gold cardboard, a barcode printing method and a packaging product processing method. Background technique [0002] In the packaging industry, in order to meet the needs of consumers for decorative effects, especially for some high-end products, printing technicians will use aluminized paper as the printing carrier of packaging products. This kind of aluminized paper has a thin layer of aluminum on the surface, which will Let the product have a metallic texture, making the printed matter look luxurious and popular with consumers. Especially on cigarette packaging paper, a layer of golden yellow pigment is coated on the aluminized paper to make the surface appear golden effect, which is commonly known as gold cardboard, which can improve the grade of cigarette packaging. [0003] However, when technicians use gold cardboard as the sub...
