The temperature of the water vapor spraying can be set to be less than 50 ℃, the humidity is 30-80%, and the mist amount of the spraying device is 3-18 kg/h. The thickness of the sprayed water vapor layer is 10um. And evaporating and drying the water vapor after the imprinting and curing are finished. The thickness of the water vapor layer is very thin, so that the micro-nano structure deep imprinting replication is not influenced, but the isolation effect can be realized, and the problem of difficult demolding is well solved. In addition, in the embodiment, the release agent is filled in the die pressing process, and a separate coating process is not needed, so that the process flow can be simplified, the equipment length can be shortened, and the production efficiency can be improved. The UV curing means may be irradiation with an ultraviolet curing lamp 13.

In other embodiments, the fourth step is not limited to metal deposition to form a plating layer, and different manners may also be adopted according to needs, for example, color ink is filled in the micro-nano structure to form a color layer. Or the step four is not provided, namely metal deposition is not carried out, and the surface composite substrate with the micro-nano structure is directly arranged on the UV resin coating. The composite substrate in the fifth step is not limited to glue, and other different modes can be adopted.
