Thus, when step (25) is executed, the stamp only keeps the stripes or the concave points on some strokes of the characters, and the other part of the stamp blank does not have the stripes or the concave points, so that the stamp and the stamp are relatively complete and beautiful.
Thus, a method for automatically identifying the authenticity of the seal impression by means of an electronic device is obtained.
In this way, in the seal making process and the identification method of the seal stamp text, because the print blank stripes or pits can be made by the print blank manufacturer and supplied to the engraving factory in batch, and then the engraving factory engraves characters on the print blank with the stripes or pits provided by the print blank manufacturer, the reference positions of the print blank are difficult to be consistent in the two processes, and the position and the direction of the intersection of the stripes or pits and the character strokes are random, so that the print blank can be used as an identification mark for anti-counterfeiting.
The obtained seal, the seal making process and the identification method of the seal stamp are characterized in that the strip or the concave point of the stamp blank is provided with a concave part with width, in the subsequent engraving of the characters, the part outside the characters on the stamp blank is dug out to enable the characters to be protruded, meanwhile, at the intersection of the strip or the concave point and the characters, partial concave parts of the strip or the concave point can be still reserved on the related strokes of the characters, although the strip, the concave point and the characters can not have randomness, due to the randomness of the engraving positions of the characters, the intersection positions of the strip or the concave point and the characters can have randomness, and the positions and the directions of the partial concave parts can be embodied in the seal stamp texts used in the future, particularly the structure, the strokes and the strokes of the characters in the seal stamp texts, the positions where the strip or the concave point are more easily displayed, thereby being used as the basis of the identification of people by naked eyes or machines, can form the anti-counterfeiting mark of the seal impression.
Because the stripes or the concave points and the name characters are crossed at a plurality of positions, residual partial concave parts can be reserved at a plurality of positions, and the residual partial concave parts can be used as the basis for identification together, so that the anti-counterfeiting accuracy of the seal imprint is greatly improved.
The invention of the seal imprint identification method enables the seal to be simply engraved by adopting machinery, and the seal imprints of the seals can provide sufficient random anti-counterfeiting marks so as to be more accurately identified.
The identification method of the seal stamp of the invention has the advantages that the stripes or the pits only remain in the character strokes, and therefore, the corresponding positions can be quickly and accurately found during the data comparison, and the identification method has the advantage of quicker comparison.
In addition, the width of the stripe or the diameter of the concave point is 0.24-0.3 mm, so that the printed text can be ensured to have enough clear gaps or blank points, and meanwhile, the character strokes can be ensured not to be interrupted so as to influence the accurate meaning of the characters.
