Embodiment 1

[0042] An embodiment of the present application provides a method for printing an anti-counterfeiting image, including:

[0043] S101. Acquire a YMCK image of a target image.

[0044] YMCK image (also known as CMYK image, printing four-color mode image) is a color registration mode used in color printing. Using the principle of color mixing of three primary colors of color materials, plus black ink, a total of four colors are mixed and superimposed to form the so-called "full-color image". print". The four standard colors are: Y: Yellow = yellow; M: Magenta = magenta, also known as 'magenta'; C: Cyan = cyan, also known as 'sky blue' or 'blue'; K: blacK = black. In the embodiment of the present application, the YMCK image of the target image is used as the basis of the printed anti-counterfeit image, which can ensure that the printed anti-counterfeit image has stronger color contrast, more vivid image color, good imaging, high image clarity, and is easy to be corresponding A...

Embodiment 2

[0067] In the second aspect, based on the anti-counterfeiting image printing method described in Embodiment 1 of the present application, the embodiment of the present application also provides an anti-counterfeiting image printing device, such as figure 2 as shown, figure 2 It is a schematic structural diagram of an anti-counterfeiting image printing device 20 provided in Embodiment 2 of the present application. The anti-counterfeiting image printing device 20 includes:

[0068] Obtaining module 201, for obtaining the YMCK image of target image;

[0069] The first extraction module 202 is used to extract the YMC channel three-color imaging pixels in the YMCK image to generate the first processed image of the target image;

[0070] The second extraction module 203 is configured to extract K-channel monochrome imaging pixels in the YMCK image to generate a second processed image of the target image;

[0071] A determining module 204, configured to determine a first target p...

Embodiment 3

[0081] The embodiment of the present application also provides a computer storage medium on which a computer program is stored. When the program is executed by a processor, the method for printing an anti-counterfeit image as described in any one of the above-mentioned embodiments of the present application is realized. The anti-counterfeit image Printing methods include but are not limited to:

[0082]Get the YMCK image of the target image;

[0083] Extract the YMC channel three-color imaging pixel in the YMCK image to generate the first processed image of the target image;

[0084] Extract the K channel monochromatic imaging pixel in the YMCK image to generate the second processed image of the target image;

[0085] determining a first target printing position of the first processed image and a second target printing position of the second processed image;

[0086] The first processed image is printed on the first target printing position, and the second processed image is...

Abstract

The invention provides a printing method and device of an anti-fake image and a related product. The printing method of the anti-fake image comprises the steps that a YMCK image of a target image is acquired; extracting YMC channel three-color imaging pixels in the YMCK image, generating a first processing image of the target image, extracting K channel single-color imaging pixels in the YMCK image, generating a second processing image of the target image, and determining a first target printing position of the first processing image and a second target printing position of the second processing image; and printing the first processed image on the first target printing position, and printing the second processed image on the second target printing position to generate an anti-counterfeiting image. According to the anti-fake image printing method, the YMC color image and the K color image are extracted, the anti-fake image is generated in the printing mode, printing of the corresponding positions of different color channel pixels of the target image is achieved, the technical threshold is high, the definition of the anti-fake image is high, and the anti-fake performance is good.

Description

technical field [0001] The present application relates to the field of printing technology, and in particular to an anti-counterfeiting image printing method, device, and related equipment. Background technique [0002] With the development of society, various smart cards, such as work permits, medical insurance and social security cards, membership cards and other smart cards, are more and more used in people's daily life. Carrying a large number of users' personal information, therefore, the non-reproducibility and security requirements of smart cards are very high. At present, in order to prevent smart cards from being copied and forged, anti-counterfeiting images are often printed on the surface of smart cards to ensure the authenticity of smart cards. sex and safety. However, at present, the anti-counterfeiting images set on the surface of smart cards in the industry are mainly generated by simple overlay printing using the printing process of RGB three-color channels....
