Seal, seal manufacturing process and seal impression identification method

Abstract

The invention discloses a seal, a seal manufacturing process and a seal impression identification method, and relates to how to form an identification mark in a seal engraving manufacturing method, transfer the identification mark to the seal impression and achieve the anti-counterfeiting of the seal impression. It is mainly characterized in that stripes or pits with a certain depth are formed onthe surface of a seal blank by a seal blank manufacturer, and characters are carved on the seal blank by an engraving factory, so that the stripes or pits are intersected with character strokes, and the stripes or pits at the intersection are reserved at the related strokes of the characters and are used for identifying and preventing counterfeiting. According to the seal, the seal manufacturing process and the seal impression identification method, the seal can be simply and automatically engraved by a machine, and the seal impression can provide sufficient random anti-counterfeiting marks for accurate identification.

Description

technical field [0001] The invention belongs to a seal and its production and use identification, and relates to how to form an identification mark in the production method of seal engraving, especially a method for identifying the authenticity of the seal text in use. Background technique [0002] Traditionally, seals are made by manual engraving. Due to different engraving personnel, and because the same engraving personnel have different engraving strength and character spacing at different times, the font, font size, font distribution and character spacing of each seal are different. It can show its own characteristics, and the seal is not easy to be counterfeited, especially with the development of electronic equipment and network technology, people can compare the original seal and the current seal at any time, making the phenomenon of seal counterfeiting Obtain effective containment, but, there is need a large amount of skill personnel in artificial engraving making s...

Problems solved by technology

[0002] Traditionally, seals are made by manual engraving. Due to different engraving personnel, and because the same engraving personnel have different engraving strength and character spacing at different times, the font, font size, font distribution and character spacing of each seal are different. It can show its own characteristics, and the seal is not easy to be counterfeited, especially with the development of electronic equipment and network technology, people can compare the original seal and the current seal at any time, making the phenomenon of seal counterfeiting It has been effectively curbed, but artificial engraving and making of seals requires a large number of skilled personnel, and there is a problem that it takes a lot of time

[0003] At present, engraving is a special industry that requires qualifications and must be registered with the public security department before it can be opened to the outside world. Due to the constraints of the number of technicians and production time, the industry has adopted computer-controlled machinery to engrave seals, that is, the machine engraves seals on the stamp base. Engraving the name, the authenticity of this kind of seal can only be identified by font, font size, font distribution and word spacing, etc. However, this practice has great defects in reality, and it is difficult to form a unique seal on the seal. As far as the existing technical means are concerned, due to the limited number of fonts, the font size, font distribution, and word spacing can all be adjusted by the machine, and criminals can completely select the font, font size, and font based on the obtained seal. Distribution and kerning to imitate a seal, and imitate the printed text produced by the seal, so as to deceive people with fake ones

[0004] In the prior art, although the means of suppressing characters on the lead has appeared, and the identification is carried out by the intersection of the characters and the random lines of impurities in the lead, it can only achieve the effect of identifying the lead, and the seal and the lead The only difference is that firstly, the stamp is not metal lead, even if it is made of lead material, it is impossible for the imprint produced by lead to transfer its texture to the printed text, and it is impossible to produce marks on the printed text. The material does not have natural texture, and the text is engraved on the stamp, and the text itself cannot produce random marks
