Degree is 24-100um, is mainly determined according to the thickness of focal plane imaging, is applied according to market, focal plane imaging thickness is generally
15-100um。
The graph text information layer 3 is to use made of UV resin, is bilayer or multilayer structure, and each layer includes picture and text
Information area, background area and ink layer, the relatively described background area in graph text information region are concave, the ink layer
The negative area being covered on where the graph text information region, to prevent the prominent substrate of ink layer that ink is caused to fall off or shell
From.
Institute is further, and the UV resin of the graph text information layer 3 can be ultraviolet using acrylic compounds identical with lens jacket 1
Light-cured resin, can also use different UV resins, and the selection of UV resin is mainly according to the size of product lenticule and final
Depending on thickness requirement, lenticule is smaller, and required UV resin viscosity is lower, and wellability is better, for example, lenticule diameter in 40 um
It is below, BH120 (100cps/25 DEG C) UV resin of new material Science and Technology Ltd. is thought using Nanjing wrestle；When lenticule
Diameter is greater than 40um, using 1551S (1200cps/25 DEG C) UV resin of TaiWan, China De Yuan group.
When making graph text information layer 3, UV resin is injected after micro- picture and text template to the lower surface for being bonded in the substrate layer 2,
It is formed by UV illumination curing, sloughs micro- picture and text template, then pass through such as flexo, silk screen, intaglio plate, the printers such as relief printing plate using ink
Skill accurately wipes graph text information region, is coloured, and so that graph text information region is had ink and is highlighted, after ink solidification
Next layer of bonding can be carried out, and so on, so as not to it is fuzzy.
Further, the graph text information region of 3 each layers of the graph text information layer can using same color ink into
Row coloring, the ink that different colours can also be used are coloured.It should be noted that the graph text information region when each layer uses
When the ink of different colours is coloured, the color of answering comparative selection degree big is in order to avoid interfere with each other, as first layer uses warm colour
Ink, the second layer use cool colour color ink.
Further, the rule such as the graph text information on the graph text information layer 3 and the lenticule on lens jacket 1 is arranged, such as
Shown in Fig. 4, each layer of graph text information, which can synchronize, to be arranged on the vertical line of lenticule focus place, because there is depth imaging
Difference, observer can observe that the graph text information of upper and lower level moves downward upwards respectively, to generate visual difference；It can also be as
Where Fig. 5, dislocation shown in fig. 6 are arranged in lenticule focus around vertical line, the arrangement spacing R1 of graph text information A, B, C,
R2, R3 can be the same (i.e. R1=R2=R3), although R1=R2=R3 is consistent in planar dimension, their imaging is
In longitudinal (i.e. product thickness direction), there is certain micro- spacing on longitudinal direction, so causing the mistake in focal plane imaging rule
Position, R1, R2, R3 can also be finely tuned, for example the graph text information A repetition arrangement spacing R2 of first layer is big by 0.25 ‰-relative to R1
When 1 ‰, such graph text information A are observed through lens jacket 1, floating effect can be shown, correspondingly, the picture and text on the second layer are believed
It ceases B and repeats arrangement spacing R3 to be small by 0.25 ‰ -1 ‰ relative to R1, when such graph text information B is observed through lens jacket 1, can show
Sinking effect is shown, so the arrangement spacing of the graph text information on graph text information layer 3 can need to only guarantee a picture and text with can be different
The rule distribution of the corresponding lenticule of information.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
