Description

The holographic version of texture is stepped on by a kind of U.S.A

Technical field

The utility model is related to anti-counterfeit package printing technology, specifically discloses a kind of U.S.A and steps on the holographic version of 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 step on the holographic version of texture there is provided a kind of U.S.A for prior art problem, the holographic version has reliable Antiforge function and stronger printing adaptability.

To solve prior art problem, the utility model discloses a kind of U.S.A and steps on the holographic version of texture, and holographic version, which is provided with, to be used for The embossment reproduction image of moulding replication, embossment reproduction image includes stepping on the pixel of texture with U.S.A, and pixel is arranged regularly to be formed With the diffraction block region for determining direction, some diffraction block regions with different diffraction angle constitute holographic cell, several Holographic cell makees cycle seamless arrangement in transverse direction and longitudinal direction.

Further, pixel is square.

Further, the area of single pixel point is 0.0025mm²。

Further, 508 pixels are distributed in per inch embossment reproduction image.

Further, the size of holographic cell is 24.2mm × 24.2mm.

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 texture is stepped on by a kind of U.S.A of the present utility model, has difference by some The holographic cell of angle of diffraction makees cycle seamless arrangement, and holographic version is presented coherent periodicity U.S.A and steps on grain effect, and embossment reproduces As the attractive in appearance, space of a whole page is seamless, printing adaptability is strong, the holographic version that antifalse effect is good, anti-counterfeiting characteristic is high can be obtained with low cost.

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：

The holographic version of texture is stepped on by a kind of U.S.A, and holographic version is provided with the embossment reproduction image for moulding replication, passes through digital hologram Litho machine engraving is formed, and embossment reproduction image includes stepping on the pixel of texture with U.S.A, and texture is stepped in space rhombus staggered effect by U.S.A. Digital hologram litho machine is imaged comprising laser 11, beam shaping device 12, the first imaging len 13, aperture 14, second Lens 15, holographic light-sensitive version 16 and digital holographic lithography machine control system 17；The narrow laser beam 21 that laser 11 is produced passes through peace Loaded on the beam shaping 12 on electric rotating machine, form the first divergent laser beam 22, the first divergent laser beam 22 by first into As the first convergent laser beam 23 of formation of lens 13, the first convergent laser beam 23 is formed by the shaping filter of square aperture diaphragm 14 Second divergent laser beam 24, the second divergent laser beam 24 forms high-quality second convergent laser beam by the second imaging len 15 25, the second convergent laser beam 25 forms a small hole real image 26 in the latex plane of holographic light-sensitive plate 16, is formed after exposure The pixel of texture is stepped on U.S.A.It is preferred that, pixel is set to square, and the area of single pixel point is 0.0025mm², it is vertical and 508 pixels are dispersed with horizontal direction in per inch embossment 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.

The pixel for stepping on texture with U.S.A is arranged regularly to form the diffraction block region with direction is determined, some to have not Diffraction block region with angle of diffraction with respective shape and position is constituted holographic cell.The pixel geometry of default holographic cell 27 Sequence, digital hologram photoetching machine control system 17 is according to the pixel geometry sequence of the holographic cell 27 preset, to fixed holographic The two-dimentional precision displacement platform stepper motor of light sensitive plate 16 sends displacement commands, and control laser 11 realizes that individual element point is seamless Different-time exposure, record steps on the holographic cell 27 of texture with seamless U.S.A in holographic light-sensitive version 16, and the diamond-shaped pattern of texture is stepped on by U.S.A Case is interlaced to make dynamic change, and distribution has spatial depth, and on a direction of observation, the Deep Canvas that texture is stepped on by U.S.A is notable. The size of holographic cell 27 is typically set to 24.2mm × 24.2mm.

Several holographic cells 27 make cycle seamless arrangement in transverse direction and longitudinal direction, are answered by carrying out electroforming to holographic cell 27 System, general to be replicated using nickel metal plating, holographic version is presented coherent periodicity U.S.A and steps on texture embossment reproduction image, finally gives big Holographic version is stepped on by the seamless U.S.A of breadth.It is preferred that, holographic version book size is not less than 650mm × 820mm.

Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed, But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
