Description of the invention: [Technical field to which the invention belongs] The present invention belongs to the technical field of avoiding color file copying by gray scale, and specifically refers to a method of using color color registration technology to prevent the file from being copied by gray scale. Modules and their methods to achieve the effect of document confidentiality. [Prior Art] In recent years, with the advancement of technology, the energy of R&D, design and manufacturing of industrial products is getting higher and higher, and the competition among peers is becoming more and more fierce. Therefore, for various R&D and design within the company. Secrecy work with documents such as manufacturing has also become more and more important, and various security technologies have been continuously developed, such as encryption technology for electronic documents. As for the confidentiality of paper documents, there is currently no effective confidentiality other than watermarking. The way, therefore, can only proceed from the entry and exit control of documents, but this practice often causes inconvenience and troubles for staff to carry out research and development, design and manufacturing, and even affects the progress and success opportunities of R&D, design and manufacturing; ❹ But in fact, In terms of chromatics, human eyes have receptors for short (s), medium (M), and long (L) wavelengths of light [called cone cells]. So in principle, three parameters describe the color perception. Any particular method of associating three numbers [or tristimulus values] for each color is called a color space; the CIE 1931 color space is one of such color spaces. But the CIE XYZ color space is special because it is based on the direct measurement of human color vision and serves as the basis for defining many other color spaces. The CIEXYZ color space was derived from a series of experiments conducted by W. David Wright (Wright 1928) and John Guild (Guild 1931) in the late 1920s 3 201020811. Their experimental results are incorporated into the CIE RGB color space. The CIE XYZ color space is derived from it. In the CIE XYZ color space, the tristimulus values are not the s, Μ, and L stimuli of the human eye, but a set of tristimulus values called χ, γ, and Ζ, which are roughly red, green, and blue, respectively. And use the CIE 1931 ΧΥΖ color matching function to calculate. Two sources of light mixed by different wavelengths of light can exhibit the same color. Hering proposed a "opposing color theory", which mainly has a specific range of opposite colors in any color of the light spectrum, that is, if any color is the background color, it appears to be in the background color. The opposite color on the screen will not be effectively displayed when it is copied by gray scale. In other words, if the "opposite color doctrine" can be applied to the confidentiality of documents, it is believed that the paper documents can obtain the required confidentiality requirements, and now some practitioners use this technology to sell pre-formed papers with specific background colors. Then print the contents of its opposite color on the paper to prevent the file from being copied by grayscale. However, in fact, the user's selection of the color of the content is inappropriate, and the effect of the protection is not obvious. What's more, because the color of the background color is fixed, the color of the internal color is relatively limited, which can not meet the different color requirements of the user, which affects the confidential work. In view of this, the inventor still deeply explores the problems faced by the aforementioned paper documents, and based on the general paper confidentiality requirements to avoid the need to be copied again, actively seeks solutions, and continues to study hard. And development, and finally succeeded in creating a funeral module and method for preventing the file from being copied by gray scale using color color registration technology to overcome the problem that existing documents are easily copied. 201020811 [Summary content]
