The invention relates to a silver-
coating printing process for a
paperboard of a cigarette case. The silver-
coating printing process comprises the following steps: (1) a
laser engraving gravure printing plate is adopted; (2)
silver ink for gravure printing is prepared; (3) the
silver ink is transferred to the surface of the white
paperboard by adopting gravure printing; (4)
DNA anti-counterfeitingink is overprinted onto the white
paperboard coated with a silver base by adopting gravure printing; (5) color ink is overprinted onto the white paperboard coated with the
DNA anti-counterfeiting inkby adopting gravure printing; and (6) UV curable
varnish is printed on the white paperboard by adopting gravure printing. The
silver ink prepared in the silver-
coating printing process provided by the invention is good in silver
powder leveling property, strong in
adhesive force, high in glossiness, and suitable for the large-area
silver paste solution printing operation of a gravure printing
machine; through
DNA anti-counterfeiting ink printing, the anti-counterfeiting effect of the cigarette case is improved; and accordingly, the cigarette case has a unique anti-counterfeiting identity forauthentication as well as the characteristics of being easy to identify and difficult to copy.
