Description
Technical field
The present invention relates to a kind of anti-copy paper and preparation method thereof.
Background technology
Paper is the important carrier that information is propagated, and " in black and white " is widely used in every field as a kind of means of retaining evidence or logging machine confidential information.Continuous development along with science and technology; Also at full speed the developing of reprography for paper document; The high-quality copier that is occurred at present can access and original paper and approaching copy thereof; Almost can reach the stage of mixing the spurious with the genuine, this just makes that whether classified papers and documentary evidence etc. are that the file that original paper has a strict demand is faced with problem how to distinguish original paper and copy to file.In addition, in the routine office work field, copier is the most indispensable auxiliary equipment in the business automation equipment, also is the office equipment that the most vast clerical workforce can both touch easily therefore.Though being widely used of copier improved office efficiency greatly, because the instrument that makes things convenient for that the popularity of its use colony that faces also makes copier become divulges a secret, steals secret information.Because, owing to copier can be contacted and used easily, so the confidential document data is easy in transmittance process owing to being caused out of control by duplicating.Therefore, the situation that avoid confidential document to be duplicated easily and cause divulging a secret, steal secret information takes place, and except strengthening the management and control to copier, making confidential document itself have anti-copy function also is a direction that is worth further investigation.
A kind of method that makes paper itself have anti-copy function in the prior art is on the paper substrate body, to form the more shallow shading-duplication preventing that can not hinder normal reading of gray scale.The component of said shading-duplication preventing generally comprises background patterns district and caution literal field; Wherein warn general employing of literal field and be used as warning shading like character strings such as " the illegal duplicating ", " forbidding duplicating ", " COPY "; The way of prior art is to adopt the smallest point that can read than duplicator (also to be; The read-out resolution smallest point of duplicator) want big point to come to form background patterns at paper surface; Adopt the also little point of smallest point that can read to form above-mentioned then as caution character strings such as " the illegal duplicating ", then two kinds of patterns are mixed, just can make the reader find above-mentioned caution character string from paper surface easily through setting suitable gray scale like this than duplicator; And when this paper is duplicated; Can't read the caution literal of caution literal field because duplicator is merely able to read the point in the background patterns district, therefore the caution literal will display with the form of blank on copy, thereby can distinguish original paper and copy.
Yet; The point that available technology adopting has different sizes to give paper anti-function of duplicating at paper surface formation background area and caution literal field; But in actual production such situation can often appear; When using Chinese to be used as warning the literal use, the concealment effect of caution literal is also bad, can be easy to identify from paper.Discover; The main cause that produces this problem is that the special construction by Chinese character itself causes, because the Hanzi structure more complicated, the stroke of single Chinese character often presents the situation that density differs on distributing; For example " answer " word; Its stroke be distributed as that the middle part is closeer relatively, periphery is lax relatively, so prior art often will compare comparatively dense owing to intensive stroke causes forming this regional site using stroke to distribute closeer Chinese character when being used as warning literal; Will be easy to make the caution literal of formation to come out like this, make the caution literal lose the ability of hiding from the background patterns saliency.Therefore; Prior art in use Chinese character as caution during literal; Usually need adjust repeatedly and avoid above-mentioned situation to take place, can prolong the production process that anti-copy paper is opened so undoubtedly, and then cause a series of unfavorable factors such as production cost rising the distribution of site.
