The invention discloses a multifunctional micro-nano structure color film production device and a work method. The multifunctional micro-nano structure color film production device comprises an unreeling device which unreels a plastic film, a drawing device which draws the plastic film so as to convey the plastic film forward, an intaglio printing device which performs image-text printing on the plastic film, a first drying oven heating system which performs printing ink drying on the plastic film, a scraper coating device which coats the surface of the plastic film with a resin layer, a second drying oven heating system which performs resin layer drying on the plastic film, a micro-nano structure impressing device which performs micro-nano structure image impressing, a cooling device which performs cooling on the plastic film, a coiling device which coils the plastic film and a bridge crossing guide roller which guides feeding of the film, wherein the intaglio printing device and themicro-nano structure impressing device realize printing image-text and micro-nano structure image-text overprinting. The multifunctional micro-nano structure color film production device can realize production of a micro-nano structure color film, and can does not use printing ink for printing at all or only use a small amount of environmentally-friendly ink for the printing.
