Description
Technical field
The present invention relates to stereoscopic print technical field, especially relate to a kind of bore hole stereoscopic print and preparation method thereof.
Background technology
Owing to there being certain distance between the eyes of people, between right and left eyes and object, shape forms an angle, and the object causing right and left eyes to see exists nuance, produces parallax, and this parallax reflects and just creates space multistory sense in brain.The grating stereo printing optical effect by grating, makes the right and left eyes of people see two different points of view figures of same object, and then merges at brain, and produce the depth image with parallax stereoeffect.
The stereo display technique of microlens array grating proposed as far back as 1908, but the rigorous being limited to microlens array process technology is high, and the difficulty that processes of earlier picture optics synthesis and be difficult to realize.In phase late 1920s, several scientists propose Lenticular screen.At present stereosopic printing false proof with the most use be exactly column mirror grating stereo antiforge technology.
But, only exist horizontal parallax from the stereoscopic print being made up of column mirror grating, there is not vertical parallax, say, that beholder can only see stereoeffect in the horizontal direction, the most then can't see stereoeffect, this is the defect that column mirror grating technology itself is existing.
Summary of the invention
It is an object of the invention to provide a kind of bore hole stereoscopic print, the stereoscopic print made to solve column mirror grating technology of the prior art does not sees the technical problem of stereoeffect in vertical direction.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
The bore hole stereoscopic print that the present invention provides; including: clear sheet; the front of described clear sheet is provided with micro-lens arrays layer, and the back side of described clear sheet is provided with micro-picture and text array layer and macrograph pattern layer, and the back side of described macrograph pattern layer is provided with protective layer；Wherein, described micro-lens arrays layer includes the lenticule of the segment shape of some array arrangements, described micro-picture and text array layer includes micro-picture and text of some array arrangements, described micro-lens arrays layer coordinates to produce three-dimensional stereo effect with described micro-picture and text array layer, described microlens array and described micro-picture and text array are rectangular array, the extended line direction often arranging micro-picture and text in described micro-picture and text array layer is 45 ° with the length direction angle of described micro-picture and text array layer, the angular range often arranged in described micro-lens arrays layer between described lenticular extended line direction and the length direction of described microlens array is 0 °-10 °.
Preferably, the distance between described lenticule adjacent in described microlens array is X, and the distance between described micro-picture and text adjacent in described micro-picture and text array is X ± 10%X.
Preferably, described micro-lens arrays layer is formed by the printing of 3D printing type by transparent UV curable ink.
Preferably, the thickness range of described clear sheet is 0.2mm-1mm.
Preferably, described clear sheet is made up of PET, polypropylene or polyvinyl chloride.
Preferably, described protective layer is printed by field printing mode by white UV curable ink and is formed.
Preferably, described lenticular diameter range is 60 μm-500 μm.
Preferably, described micro-picture and text array is printed by field printing mode by spot color UV curable ink and is formed, described micro-picture and text generally circular in shape, and a diameter of 60 μm-500 μm.
Preferably, described macrograph pattern layer includes colour or the pattern of black and white printed by UV curable ink.
Relative to prior art, bore hole stereoscopic print of the present invention has the advantage that
The bore hole stereoscopic print that the present invention provides provides the benefit that: provide a kind of simpler production one bore hole stereoscopic print by the way of printing, printing, manufacture craft is simple, there is not the cross-interference issue that post lens stereoscopic print of the prior art in press occurs, and the bore hole stereoscopic print image of present invention offer is clear, omnibearing stereo effect is notable, all be can watch stereoeffect in the horizontal direction with vertical direction by bore hole；Can be applicable to the fields such as entertainment card, toy, novel package, to strengthen the sight of corresponding product, interest.
Simultaneously because the micro-picture and text in the bore hole stereoscopic print of present invention offer cannot obtain with tradition copy method, when therefore the bore hole stereoscopic print that the present invention provides being applied to stereosopic printing anti-counterfeit field, the antifalse effect of this bore hole stereoscopic print is good, technically reliable, and market application foreground is wide.
Another object of the present invention is to propose the preparation method of a kind of bore hole stereoscopic print, the stereoscopic print made to solve column mirror grating technology of the prior art does not sees the technical problem of stereoeffect in vertical direction.
