S101. Etching Holder's Identity Information by Laser
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. Printing Color Portrait in the Blank Space
A color ink is used to print the color portrait in the blank space of the substrate to obtain a personalized data surface; the color portrait is an enlargement of the black-and-white portrait in equal proportion; in this embodiment, the color portrait which is an enlargement of the black-and-white portrait in equal proportion is printed in the blank space of the substrate; since the color portrait is directly printed in the region without laser etching, the color portrait will not overlay the black-and-white identity information, and the black-and-white identity information does not affect the color of the color portrait, the color portrait is therefore more vivid; and since the black-and-white portrait is consistent with the color portrait, it will not match the color portrait falsified. In this embodiment, the color portrait can be verified by the smaller black-and-white portrait, which effectively enhances the anti-counterfeiting feature of the secure identification document.
S103. Printing a Transparent Protective Layer
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 portrait. Since the transparent protective layer covers the color portrait, it can protect the color portrait and effectively prevent falling of the color portrait due to daily use.
In order to better explain the invention, the method for producing the secure identification document of the present invention is described in details with another embodiment below. Please refer to
S201. Etching Holder's Identity Information by Laser
The holder's identity information is etched by laser on the substrate of the data surface; the substrate comprises polyvinyl chloride (PVC) or polycarbonate (PC), and the holder's identity information comprises the black-and-white portrait and the text information; wherein the black-and-white portrait 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 that has been etched can have a change in color, or even a change in surface depth; the laser etches the holder's identity information on the substrate in a destructive manner, so it is difficult to falsify the identify information.
S202. Printing the Color Portrait in the Blank Space
Color portrait is printed with color ink in the blank space of the substrate to obtain the personalized data surface; the color portrait is an enlargement of the black-and-white portrait in equal proportion; wherein, the color ink comprises color resin ink or offset rotary ink; in this embodiment, the color portrait which is an enlargement of the black-and-white portrait in equal proportion is printed in the blank space of the substrate; since the color portrait is directly printed in the region without laser etching, the color portrait will not overlay the black-and-white identity information, and the black-and-white identity information does not affect the color of the color portrait, the color portrait is therefore more vivid; and since the black-and-white portrait is consistent with the color portrait, it will not match the color portrait falsified. In this embodiment, the color portrait can be verified by the smaller black-and-white portrait, which effectively enhances the anti-counterfeiting feature of the secure identification document.
S203. Generating an Optically Variable Mark
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 marks is more than one.
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, changing the arrangement of liquid crystals. Then, the optically variable mark is rapidly cured by an UV curing agent or ultraviolet light.
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, the 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 Mark
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 portrait; and the 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 a second anti-counterfeiting mark; for example, the transparent protective layer is printed in the form of a seal to cover the color portrait; or when the transparent protection layer is printed, the printing thickness of the predetermined region in the protective layer is increased or reduced, 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 marks can be one or more than two; wherein when the number of the second anti-counterfeiting marks 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 portrait, the transparent protective layer shall be destroyed before the color portrait 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.
The invention greatly enhances the anti-counterfeiting feature of the secure identification document by overlaying and printing the color portrait and setting the first and second anti-counterfeiting marks.
