In the distortion of Fig. 4 (e), oval-shaped intaglio layer 24 is centered on by surrounding edge boundary region 58 in addition, and it is printed with the highlight color covering surfaces.For example, the line pattern 60 of borderline region 58 has the angle direction of subregion 46, and is printed with the live width b of 100 μ m and the line interval a of 90 μ m.Advantageously, background layer 22 and intaglio layer 24 are aimed at mutually, and the border of background layer 22 is covered by surrounding edge boundary region 58.Possible alignment change between background layer 22 and intaglio layer 24 is hidden by borderline region the observer.
The distortion of Fig. 4 (f) is similar to the deformation design of Fig. 4 (e), and just the line pattern 60 of surrounding edge boundary region 58 has with first type surface and comprises line pattern 42 and 44 different angle directions in the subregion 46 of information.In the exemplary embodiment, for example, the angle direction of borderline region 58 center lines is 0 °.Shown in Fig. 4 (a), subregion 46 is provided with positive boundary contour.
Another distortion of Fig. 4 (g) only is different from the distortion of Fig. 4 (e) by the wide especially information of negative boundary contour 52, it gives lay special stress on to the subregion 46 that comprises information.
Should be appreciated that, every kind of distortion of the intaglio layer among Fig. 4 can with the distortion combination of each background layer 22 among Fig. 3.
(a)-(c) expression is by the sectional view of the intaglio layer 24 of different live width b and line interval a ratio among Fig. 5.In this article, the intaglio layer needn't adopt consistent ratio at whole surface area, but each embodiment of Fig. 5 (a)-(c) can appear at the different subregions of intaglio layer.
In the embodiment of Fig. 5 (a), a is just less times greater than live width b at interval for line, and for example, live width is 100 μ m, and line is 110 μ m at interval.Like this, intaglio printing inks is applied on the whole surface, still, and the thickness of concrete quite big variation.Thereby it is out of question to visually see line, and still, it is very dark that whole surface appears to.The colour switching effect of liquid crystal layer 30 is very outstanding in the zone of this intaglio layer.
At the embodiment at interval of wide line shown in Fig. 5 (b), for example, line is spaced apart 160 μ m, and live width is 130 μ m.In the interval 62 that does not have printing-ink, can see the background layer 22 or the banknote substrate 20 that in Fig. 5 (b), do not have expression.Thereby single line even clearer to human eye, the overall impression on surface is brighter.Like this, the effect of liquid crystal layer 30 is more weak than the embodiment of Fig. 5 (a).
At last, the zone of single line overlap in Fig. 5 (c) expression intaglio layer 24, that is, line interval a is less than live width b.For example, live width b is 130 μ m, and line a at interval can only have 110 μ m.In this article, live width depends on non-overlapped line 64 (in Fig. 5 (c) shown in the dotted line).By this overlapping, realize the surface coverage of very high peace.This embodiment of intaglio layer is particularly suitable for the surrounding edge boundary region, and such as the borderline region among Fig. 4 58, wherein the main border of background layer 22 will be hidden.
(a) among Fig. 6 and (b) expression two more complicated exemplary embodiments of the present invention, wherein in exploded view clearly the diagram be arranged on another layer top the layer.Safety element 70 among Fig. 6 (a) has whole surface color background layer 72, on whole surface color background layer 72 intaglio layer 74 is set.Intaglio layer 74 comprises the fine structure of being made up of the parallel lines of different angles direction, and what the parallel lines of these different angles directions formed numeric string " 10 " shape comprises information subregion 76.Each subregion 76 is surrounded by negative boundary contour.
The surrounding edge boundary region 80 of intaglio layer 74 is with high surface coverage printing, makes the observer not see to be positioned at the border of the background layer 72 below the borderline region 80.
Apply liquid crystal layer 82 on background layer 72 and intaglio layer 74, its colour switching effect is especially outstanding in the non-gap of intaglio layer 74 dark areas.On the contrary, in gap 78, the colored impression of background layer 72 is started to control to make and is used.In the outside of intaglio layer 78, liquid crystal layer 82 is located immediately at above the bright bank-note paper, makes the colour switching effect of the liquid crystal pigment in fact can't see there.
Another exemplary embodiment of Fig. 6 (b) expression security element according the invention 90, wherein color background layer 92 is printed on the shape of an information, is the shape of zebra head in this article.Intaglio layer 94 comprises an information in addition in its fine structure, that is, and and numeric string " 10 ".On two-layer, apply whole surperficial liquid crystal layer 96 again.
Because notch board printed layers 94 is very close to each other in this exemplary embodiment, the optics impression is darker than the situation of the intaglio layer 74 in the exemplary embodiment of Fig. 6 (a).Yet, can clearly see color and the design of zebra 92 by the interval between the parallel lines of intaglio layer 94.
