Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can practice the invention with reference to the description.
A cardboard silver-coated printing process for cigarette packets, comprising the steps of:
1) engraving a gravure plate by laser, wherein the plate depth is between 30 and 35 mu m; the width of the opening of the gravure plate is controlled to be between 60 and 100 mu m, and the density of the dot of the gravure printing is controlled to be 3 to 5.
2) Preparing gravure silver ink;
the gravure silver ink comprises the following components in parts by weight:
the viscosity of the hexanediol diacrylate is 3000-5000, the viscosity of the lignin modified phenolic resin is 10000-30000, the particle size of the hexanediol diacrylate and the lignin modified phenolic resin is far smaller than that of the titanium dioxide coated silver powder, and the hexanediol diacrylate and the lignin modified phenolic resin are matched with each other by adopting two resins with different viscosities, so that the hexanediol diacrylate and the lignin modified phenolic resin are prevented from generating negative influence on the overall fluidity of the silver ink, and the silver ink is enabled to obtain good fluidity; the re-solubility refers to the re-dissolving capacity of the ink when encountering a solvent after the ink is dried, and the ink with weak re-solubility is easy to cause the faults of plate drying and plate blocking. To improve the re-solubility of the ink, the choice of suitable resins should be considered. The resin for the silver ink is prepared by matching hexanediol diacrylate with better redissolution capacity and lignin modified phenolic resin with better redissolution capacity, so that the problems of plate drying and plate blocking are solved, and after the silver ink is dried into a film, the ink film shows good water resistance and solvent resistance. When the plate is washed, the plate can be cleaned by adopting ethyl ester.
The gamma-mercaptopropyl trimethoxysilane is used as a modifier of the titanium dioxide coated silver powder, so that the compatibility of the titanium dioxide coated silver powder in a system is improved; the butyl methacrylate has low viscosity and good solubility, and is used for adjusting the viscosity of the ink to ensure that the ink has proper rheological property and printing testability; the N, N' -methylene bisacrylamide and the hexanediol diacrylate are matched to form a stable cross-linked network structure, so that the time for completely curing the curing system is shortened; wherein the antifogging agent is calcium stearate; the wetting leveling defoaming agent is an amino polyether modified organic silicon defoaming agent; the wettability and the thermal stability of the silver ink are improved by adding the N-dodecyl-beta-aminopropionic acid, so that the printing quality is improved.

55-80% of titanium dioxide coated silver powder with the particle size of 1-3 mu m.
Wherein the silver powder is formed by mixing 80 mass percent of granular aluminum powder and 20 mass percent of nano silicon. By adopting the titanium dioxide coated silver powder with two specifications, the titanium dioxide coated silver powder is orderly arranged, so that the internal structure is uniform, the product performance is stable, and the viscosity can be effectively reduced.
3) Transferring the silver ink to the surface of the white cardboard by adopting gravure printing; the prepared silver ink in the step 2) is adopted to print the ground color, the silver ink has the surface characteristic of metal, the glossiness is good, the defect of poor surface glossiness of the white cardboard is overcome, and the effect only printed on the silver cardboard can be printed on the white cardboard; after the silver paste is used for printing the ground color, the surface is printed with a layer of high-brightness yellow ink again, so that the ivory board has the golden gloss effect.
4) Transferring the DNA anti-counterfeiting ink to white cardboard coated with silver bottom by adopting gravure printing; the character printing adopts DNA anti-counterfeiting ink, so that the cigarette case has unique anti-counterfeiting identity authentication and has the characteristics of easy identification and difficult imitation.
5) Overprinting UV colored ink on white cardboard covered with DNA anti-counterfeiting ink by adopting gravure printing; the printing process is characterized in that four-color printing of high-brightness yellow, blue, black and transparent blue is carried out on a multicolor intaglio printing machine, transparent printing ink with good transparency is selected for pattern printing, although the transparent printing ink is overprinted on a silver substrate, the bright color of a printed product can still be ensured, the metal glossiness is high, and the production efficiency is high.
6) And printing UV gloss oil on the white cardboard covered with the UV colorful ink by adopting gravure printing, and protecting the surface of a printed product from being damaged by adopting the UV gloss oil, so that the surface smoothness is improved, and the subsequent processing is facilitated. The main components of the UV gloss oil are photosensitive resin, reactive diluent, photoinitiator and auxiliary agent, and the UV gloss oil has the advantages of high curing speed, high film brightness, firmness and heat resistance of a dried film surface, capability of enabling the surface of a printed product to be very bright and smooth, good refraction effect, strong main body feeling of pictures and texts, more bright color and high-grade printing quality.
The printing color sequence is as follows: silver, highlight yellow, DNA anti-counterfeiting ink, blue, black, transparent blue and water-based gloss oil. Firstly, silver paste is transferred to the surface of the white cardboard, so that the glossiness of the white cardboard is improved; secondly, high-brightness yellow ink printing is carried out, so that the white cardboard has a metallic luster effect; completing character printing of the cigarette case again, wherein the character printing adopts DNA anti-counterfeiting ink; then, the cigarette label pattern is printed, and the pattern printing adopts transparent ink with good transparency, so that although the transparent ink is overprinted on a silver substrate, the printed product still can be ensured to be bright in color and high in metal glossiness; and finally, the UV gloss oil is adopted to protect the surface of the printed product from being damaged, so that the surface smoothness is improved, and the subsequent processing is facilitated.
