    [0019] The following embodiment describes in details a method for producing a secure identification document according to the invention. Please refer to Fig. 1. The method comprises: S101. Etching holder's identity information by laser
    [0020] Holder's identity information is etched on the substrate of the data surface by laser; the holder's identity information comprises a black-and-white image and text information; the black-and-white image comprises a portrait of the holder, and the text information comprises: the holder's name, document number and other text information related to the holder's identity. Due to the high energy of laser, the area of the substrate surface etched can have a change in color, or even a change in surface depth; holder's identity information is etched on the substrate in a destructive manner, so it is difficult to falsify the identify information. S102. Overlaying and printing a color image
    [0021] Printing a color image on the black-and-white image with color ink, and making the color image and the black-and-white image align and coincide with each other to form a personalized data surface. In this embodiment, by overlaying and printing a color image on the black-and-white image, the portrait on the secure identification document is more aesthetic; since the black-and-white image is consistent with the color image, it will not match the color image falsified, resulting in a poor visual effect of holder's portrait. This is convenient for people to identify whether the secure identification document has been falsified or not. S103. Printing a transparent protective layer
    [0022] A transparent protective layer is printed on the upper surface of the personalized data surface by using a transparent varnish, and the protective layer covers the color image. Since the transparent protective layer covers the color image, it can protect the color image and effectively prevent falling of the color portrait due to daily use.
    [0023] In order to better explain the invention, the method for producing the color secure identification document of the invention is described in details with another embodiment below. Please refer to Fig. 2. The method comprises: S201. Etching holder's identity information by laser
    [0024] The holder's identity information is etched by the laser on the substrate of a data surface; the substrate comprises polyvinyl chloride (PVC) and polycarbonate (PC), and the holder's identity information comprises the black-and-white image and text information; the black-and-white image comprises the portrait of the holder, and the text information comprises the holder's name, the document number, and other text related to the identity of the holder. Due to the high energy of the laser, the region of the substrate surface etched can have a change in color, or even a change in surface depth; the holder's identity information is etched on the substrate in a destructive manner, so it is difficult to falsify the identify information. S202. Overlaying and printing the color image
    [0025] Printing a color image on the black-and-white image with color ink, and making the color image and the black-and-white image align and coincide with each other; and printing color text on the black-and-white text information with color ink, and making the color text and the black-and-white text information align and coincide with each other to obtain a personalized data surface. The color ink comprises color resin ink or offset rotary ink. In this embodiment, by overlaying and printing a color image on the black-and-white image, the portrait on the secure identification document is more aesthetic; since the black-and-white image is consistent with the color image, it will not match the color image falsified, resulting in a poor visual effect of holder's portrait. This is convenient for people to identify whether the document has been falsified or not. S203. Generating an optically variable mark
    [0026] The first anti-counterfeiting mark is printed on the personalized data surface with optically variable ink; the first anti-counterfeiting mark consists of a graphic and/or text, specifically comprising the graphic and/or text related to the holder's identity information, or comprising graphic and/or text not related to the holder's identity information; for example, the holder's portrait or initials or other information (e.g. a trademark or a name of document issuing authority) can be used as the first anti-counterfeiting mark, which is not defined herein; and the number of the first anti-counterfeiting mark is more than one.
    [0027] The first anti-counterfeiting mark is sequentially changed in color and cured, so that the optically variable mark is generated on the personalized data surface. Specifically, the color changing process can be realized by gas, electricity, light, or pressure, which is to change the arrangement of liquid crystals. Then, the optically variable mark is rapidly cured by an UV curing agent or ultraviolet light.
    [0028] Viewed from the front or from the side, the optically variable ink shows two different colors with the change of the viewing angle, with strong optical variability, great color difference, and obvious characteristics. The optically variable ink can be recognized without any equipment, he color angle effect cannot be reproduced with any high-definition scanner, color copier and other equipment, and the printing feature cannot be emulated with any other ink and printing method, showing good anti-counterfeiting reliability. Therefore, optically variable ink has been designated for currency and securities with the strictest anti-counterfeiting requirements in many countries in the world. In this embodiment, the optically variable mark printed with the optically variable ink is provided, which is more conducive to counterfeit prevention of secure identification document. S204. Printing the protective layer and the second anti-counterfeiting marks
    [0029] A transparent protective layer is printed on the upper surface of the personalized data surface with a transparent varnish, and the protective layer completely or partially covers the color image; since the transparent protective layer is digitally generated on the upper surface of the personalized data surface, the contour and content of the protective layer can be set according to the needs of the document issuance. Second anti-counterfeiting marks are formed in the transparent protective layer while the transparent protective layer is printed; specifically, when the transparent protective layer is printed, the contour of the transparent protective layer is printed as a predetermined graphic and/or text, making the transparent protective layer the second anti-counterfeiting mark; for example, the transparent protective layer is printed in the form of a seal to cover the color image; or when the transparent protection layer is printed, increase or reduce the printing thickness of the predetermined region in the protective layer, so that the second anti-counterfeiting mark with the graphic and / or the text is formed in the predetermined region; and the number of the second anti-counterfeiting mark can be one or more than two; wherein when the number of the second anti-counterfeiting mark is more than two, the second anti-counterfeiting marks are evenly distributed in the transparent protective layer. Since the transparent protective layer covers the color image, the transparent protective layer shall be destroyed before the color image is falsified; because the transparent protective layer is provided with the second anti-counterfeiting mark, when the transparent protective layer is destroyed, part of the content of the second anti-counterfeiting mark is inevitably lost, which is convenient for people to identify whether the content of the document has been falsified; the transparent varnish comprises resin, linseed oil or turpentine; the second anti-counterfeiting mark consists of graphic and/or text, and the content of the second anti-counterfeiting mark can be the same as or different from the content of the first anti-counterfeiting mark.
    [0030] The invention greatly enhances the anti-counterfeiting ability of the secure identification document by overlaying and printing the color portrait and setting the first and second anti-counterfeiting marks.
