Description
Technical field
The utility model is related to anti-counterfeit package printing technology, specifically discloses a kind of holographic version of space wire drawing texture.
Background technology
Antiforge laser holographic is that graph text information is made into false proof figure using laser holographic plate-making technology and moulding replication technology
Picture.At present, achievable plate-making technology has：It is dot matrix dynamic radiance, disposable special laser film, 3D optical shrinks background, colorful
Optics Random etc..Laser anti-counterfeit pattern is usually that user is observed by naked eyes, or checks interior by microscopy apparatus
Portion cuts blocks for printing feature, so as to discern the false from the genuine.Because the color lump coding in hologram is particular design, even if same equipment also is difficult to
Identical holographic mother is made, therefore laser holographic plate-making technology is widely used in anti-counterfeit package printing industry, widely uses
Technique for applying be that transfer will be made directly to hologram on paper product, be widely used in ticket, trade mark and credit card.Same masterplate
It is the same to suppress the label come, but masterplate influenceed by various parameters and environmental condition in a photolithographic process, unlikely
Identical two pieces of masterplates are made, so as to play antiforge function.With the swift and violent hair of computer technology and laser plate-making technology
Exhibition, fake producer also possesses the technology of some duplication anti-counterfeit printings；Meanwhile, with modern product package development, anti-counterfeit printing row
Industry proposes higher requirement to the book size of hologram, wants to continue to lift up the antifalse effect of laser anti-counterfeit image and printing is suitable
, there is sizable difficulty in many aspects such as technology, equipment, costs in Ying Xing.
The content of the invention
Based on this, it is necessary to which, for prior art problem there is provided a kind of holographic version of space wire drawing texture, the holographic version has
Reliable antiforge function and stronger printing adaptability.
To solve prior art problem, the utility model discloses a kind of holographic version of space wire drawing texture, and holographic version is provided with
For the embossment reproduction image of moulding replication, embossment reproduction image includes the pixel with space wire drawing texture, and pixel is by rule
Arrangement form has the diffraction block region for determining direction, and some diffraction block regions with different diffraction angle constitute holographic single
Member, several holographic cells make cycle seamless arrangement in transverse direction and longitudinal direction.
Further, pixel is square.
Further, the area of single pixel point is 0.01mm2。
Further, 254 pixels are distributed in per inch embossment reproduction image.
Further, the size of holographic cell is 40mm × 40mm.
Further, holographic version is the nickel version being made of nickel material electroforming.
Further, embossment reproduction image is formed by digital hologram litho machine engraving.
The beneficial effects of the utility model are：The holographic version of a kind of space wire drawing texture of the present utility model, has some
The holographic cell of different diffraction angle makees cycle seamless arrangement, and coherent periodic spatial wire drawing grain effect is presented in holographic version,
Embossment reproduction image is attractive in appearance, the space of a whole page is seamless, printing adaptability is strong, can obtain that antifalse effect is good, anti-counterfeiting characteristic high with low cost
Holographic version.

Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be further appreciated that, below
The utility model is described in further detail with embodiment with reference to accompanying drawing.
Fig. 1 is referred to Fig. 2：
A kind of holographic version of space wire drawing texture, holographic version is provided with the embossment reproduction image for moulding replication, passes through number
Holographic lithography machine engraving is formed, and embossment reproduction image includes the pixel with space wire drawing texture.Digital hologram litho machine is included
Laser 11, beam shaping device 12, the first imaging len 13, aperture 14, the second imaging len 15, holographic light-sensitive version 16
With digital holographic lithography machine control system 17；The narrow laser beam 21 that laser 11 is produced passes through the light beam that is installed on electric rotating machine
Reshaper 12, forms the first divergent laser beam 22, and the first divergent laser beam 22 is assembled by the first imaging len 13 formation first
Laser beam 23, the first convergent laser beam 23 forms the second divergent laser beam 24, second by the shaping filter of square aperture diaphragm 14
Divergent laser beam 24 forms high-quality second convergent laser beam 25 by the second imaging len 15, and the second convergent laser beam 25 exists
A small hole real image 26 is formed in the latex plane of holographic light-sensitive plate 16, the pixel with space wire drawing texture is formed after exposure
Point.It is preferred that, pixel is set to square, and the area of single pixel point is 0.01mm2, vertically and horizontally go up per inch embossment
254 pixels are dispersed with reproduction image.
Pixel has different angle of diffraction, and RGB gray values, digital hologram photoetching are set by digital hologram litho machine
Machine control system 17 is according to the RGB gray values preset are to the electric rotating machine of beam shaping device 12 and fix holographic light-sensitive version 16
Two-dimentional precision displacement platform stepper motor send three determination angle commands, finally make the rotation of the second convergent laser beam 25
The angle of diffraction of angle and pixel is corresponded, and forms some pixels with different diffraction angle.
