Description

A kind of composite stereo mould literary composition security stamp

The utility model relates to a kind of composite stereo mould literary composition security stamp, is used for the affirmation hereof of administration, enterprises and institutions and personal identification.

At present, anti-counterfeit of seals mainly with the printing ink of special formulation as false proof means, yet the false proof one side of printing ink can not change the plane attribute of seal literary composition, still can be taken a picture easily or scan method for platemaking and duplicate; On the other hand, the sales range of special formulation printing ink is uncontrollable, so its antifalse effect is also undesirable; As my last utility application " a kind of 3 D antiforge automatic stamp making ", the Yin Qiyin face has outstanding draw point, in use can cause to the destruction of the paper of being impressed with to the injury of human body, therefore still has weak point.

The purpose of this utility model is to overcome the defective of above-mentioned seal scheme, realizes the anti-counterfeit of seals purpose.

A kind of composite stereo mould literary composition security stamp, its surface structure is made up of seal handle, die basis and die, and its feature also is, the three-dimensional text and the symbol of useful chemical attack on the seal face of its die, manually method such as engraving or laser engraving formation.Literal that these are three-dimensional and symbol are outstanding or be depressed in seal face mould literary composition and frame, on Mo Wen and frame plane base, are combined to form compound three-dimensional characters cut in relief or characters cut in intaglio mould literary composition with the former.

When impressing with a kind of composite stereo mould literary composition security stamp of the present utility model, following specific characteristic will appear in its seal literary composition:

1 will be because of being extruded attenuation (color shoals) at the printing ink at the three-dimensional characters cut in relief place of Yin Wen, and leave over corresponding indentation trace on paper, and the vestige that printing ink is piled up (darkening) will appear in the characters cut in relief edge.

The 2 three-dimensional characters cut in intaglio place printing ink at Yin Wen will too much thicken projection because of inking.

3 above-mentioned yin, yang three-dimensional texts and symbol both can find by the ink colors depth difference of seal literary composition, also can find by beating due to the sidelight shade, also can be by observing the reflection ray capacity variance discovery of seal literary composition.

The person can't duplicate above-mentioned vestige with photomechanical production or scanning method for platemaking to adopt the utility model to make the falsification of seal, or promptly uses additive method to forge, and also can improve greatly and forge cost and difficulty; Simultaneously, seal appraiser or even ordinary person can only just can make authenticity with naked eyes not by instrument.

Below in conjunction with accompanying drawing, describe with regard to most preferred embodiment of the present utility model:
