## Background
FIELD OF THE INVENTION
The present invent relates to a method of making a laser water transfer printing film which includes a release layer for facilitating a separation of a PET film from a PVA film easily so as to use the PET film repeatedly.
BACKGROUND OF THE INVENTION
Convention method of making water transfer printing film contains steps of: coating an adhesive agent on a PET (polyethylene terephthalate) film, drying the adhesive agent, rolling a PVA (polyvinyl alcohol) film to the PET film, adhering and heating the PET film and the PVA film so that an ink layer on the PET film is printed on the PVA film. However, the ink layer is damaged easily when being printed to the PVA film. In addition, the ink layer has a lacquer coated thereon, but dusts attach on the lacquer easily. Furthermore, after printing the PET film on the PVA film, the PET film is discarded or burned, thus wasting the PET film.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a method of making a laser water transfer printing film which includes a release layer for facilitating a separation of a PET film from a PVA film easily so as to use the PET film repeatedly.
Further object of the present invention is to provide a method of making a laser water transfer printing film which obtains a thickness of the PVA film within 20 to 50 micron so as to vary metal lusters.
Another object of the present invention is to provide a method of making a laser water transfer printing film which coats a gold reservoir on the release layer to prevent an ink layer from damage in a transfer printing process.
To obtain the above objective, a method of making a laser water transfer printing film provided by the present invention contains steps of:
providing a substrate material, wherein the substrate material is a PET film rolled;
coating a release layer on one side surface of the PET film by ways of a first coating apparatus, wherein the release layer has a gold reservoir coated thereon;
semi-solidifying the gold reservoir by using a heat solidifying apparatus;
printing an ink layer on the gold reservoir by ways of a printing device;
implanting a message layer on the ink layer by means of an implanting device;
embossing geometric patterns on the message layer by using a rolling device so as to form embossed patterns on the message layer;
plating the metal layer on the embossed patterns;
coating a PVA solution on the metal layer by ways of a second coating device and drying the PVA solution by means of a drying device so as to form a PVA film on the metal layer;
separating the PET film from the PVA film by using a releasing device and then rolling the PET film which has separated from the PVA film.
Preferably, the message layer is made of any one of graphite and electricity conductive material so as to conduct electricity to the metal layer.
Preferably, the metal layer is plated on the embossed patterns in any one of a sputtering manner, a vacuum evaporating manner, and a plating manner.
Preferably, the metal layer has one surface for refracting lights.
