1) determine to intend forming the white watermark effect, such as Figure 10, the white watermark design sketch is the Chinese character " coin " that watermark recovery B presents.
2) can provide certain area to be put in design original text position in the finished product, intuitively represent the form of the pattern A of basic unit and the form of watermark recovery B.
3) intend with direct mask-making technology (Fig. 8), determine gravure printing machine and gravure China ink, the live width of miniature figure line is decided to be 0.04mm-0.12mm, height greater than 0.01mm.
4) design width of cloth gray-scale map or a binary map in basic unit, utilize form and aspect to change the shape that miniature figure line arrangement of elements is become the pattern A of basic unit, copy miniature figure line among the pattern A of basic unit to watermark recovery B layer, colourless element part (lines or colourless reticulate pattern or without color lump etc. will be added in the miniature figure line on the watermark recovery B layer, coloured and colourless element accounting example is 3: 1), direction is 0 °, guarantees simultaneously the complete of miniature figure.Structure such as Figure 10, local enlarging section C among Figure 10 show shape by the parallax in the live width of adjusting the miniature figure line element in the miniature figure line array of elements and/or miniature figure line element part, size, density, angle, highly, in the color at least one can bring visual difference, thereby so that the content revealing of basic unit's pattern or watermark recovery goes out level.In the practice, the adjustment of the visual effect of figure line can by false proof software (for example drawing the Layout+ of (Jura) company as Hungary is excellent, the softwares such as Fortuna of the dotrix department of Ai Kefa (Agfa) company) to the shape of the live width of miniature figure line element and/or the part of the parallax in the miniature figure line element, size, density, angle, highly, color automatically adjusts and realizes.
(2) plate-making:
It is 60 °-63 ° of laser angles that direct plate-making three-dimensional data is set, and the degree of depth is 0.01mm-0.10mm (two-layer depth difference is more than the 0.04mm), hold China ink layer 0.01mm, 0 ° of angle, carved gravure master or forme.Recessed master through after operation turn over the plating forme after processing can be for printing, gravure can directly be printed after later operation processing.
(3) printing:
Adopt gravure printing, make the white watermark anti-counterfeiting pattern, and in basic unit's pattern and watermark recovery, show stereovision, thereby play antifalse effect better.
Embodiment 5 and embodiment 6 utilize unobstructed, the different principle of the inside and outside height of watermark to form respectively two embodiment black, white watermark pattern, and referring to Figure 11-17, in this embodiment, the pattern A of basic unit is the landscape pattern, and watermark recovery B is literal " CBPMC ".
Embodiment 5: simulating black watermark effect (film printing down mode)
As shown in figure 11, form the pattern A of basic unit at the first film F1, the pattern A of basic unit is rendered as gravure cutting with landscape, personage etc., is formed by the combination of the multiple miniature figure line element (M1 among the figure, M2, M3 etc.) that comprises little line segment and straight line.Miniature figure line element M 1 is oblique grid wider among the figure, and miniature figure line element M 2 is oblique grid (plagioclase bar) narrower among the figure, and miniature figure line element M 3 is the pattern part of the roughly Wall bricks shape among the figure.
As described in Figure 12, on the second film F2, form watermark recovery B (being about to described watermark recovery place part entirely to deceive formal output to the second film) with complete black form.Watermark recovery is the watermark layer pattern and character " CBPMC " shown in Figure 13, and the part outside the upper literal of the second film F2 forms net.In the specific implementation, obvious for guaranteeing the watermark shape, can suitably enlarge watermark recovery.
As described in Figure 13, form the watermark recovery B of the written form corresponding with the second film at the 3rd film F3, the part at the literal place forms net.
In the specific implementation, can increase many films between the second film and the 3rd film, output content is: watermark recovery place part is complete black form, partially transparent beyond the described watermark recovery.
Making master (is mother matrix, can be used for making forme) or during forme, utilize first the first film F1 in master or forme, to make landscape, recycle the second film F2 and make it to have predetermined altitude by the printing down corrosion described basic unit of intensification pattern in master or forme, but do not deepen wherein the part corresponding to watermark recovery, and then utilize the 3rd film F3 in master or forme, to make described watermark recovery by the printing down corrosion, so that be higher than landscape part (height that for example makes the residing aspect ratio of literal degree of depth basic unit pattern greater than 20um more than) at word segment on master or the forme, master or forme side are Fig. 7, thereby form the Heisui River seal effect that word segment is higher than the landscape part when printing, printing effect as shown in figure 14.
In addition, as a kind of easier mode, in practice, also basic unit's pattern and watermark recovery all can be outputed on first film, and a separate mesh sheet is outputed to the second film.
In this case, when making master or forme, in master or forme, make described basic unit pattern and watermark recovery according to described the first film by the printing down corrosion first, and then in forme, deepen the part of described basic unit pattern and watermark recovery according to described the second film by printing down corrosion, and make it to keep complete.
Embodiment 6: simulation white watermark effect (film printing down mode)
As the same manner as in Example 5, form the pattern A of basic unit at the first film F1 (seeing Figure 11).Emphasize watermark recovery B at the second film F2 (seeing Figure 16), the part screening beyond the watermark recovery.Form watermark recovery B, the part screening at watermark recovery place at the 3rd film F3 (seeing Figure 15).In the specific implementation, obvious for guaranteeing the watermark shape, can suitably enlarge watermark recovery.
As different from Example 5, when making master or forme, after making basic unit's pattern according to the first film F1, utilize first the 3rd film F3 to make literal, recycle the second film F2 and make landscape, so that be lower than landscape part (the residing height of the aspect ratio literal degree of depth that for example makes basic unit's pattern greater than 20um more than) at word segment on the forme, master or forme side are Fig. 3, thereby form the white watermark effect that word segment is lower than the landscape part when printing, printing effect as shown in figure 17.
In addition, as a kind of easier mode, in practice, also basic unit's pattern and watermark recovery all can be outputed on first film, and a separate mesh sheet is outputed to the second film.
In this case, when making master or forme, in master or forme, make described basic unit pattern and watermark recovery according to described the first film by the printing down corrosion first, and then in forme, deepen the part of described basic unit pattern and watermark recovery according to described the second film by printing down corrosion, and make it to keep complete.
Can know, embodiment 5 and 6 also can adopt direct mask-making technology.For example, to form the white watermark effect shown in the embodiment as example, when adopting direct plate-making mode, can the degree of depth inside and outside the literal be set by the figure requirement, for example, the degree of depth of word segment (watermark recovery B) is set to 5um-40um, and the degree of depth of landscape part (the pattern A of basic unit) is set to 60um-80um.Like this, can be deeper than the landscape part by the word segment of direct platemaking equipment output on master or forme, the forme side is Fig. 3, thereby is lower than the landscape part at the money formation word segment of printing, thereby presents white watermark printing effect as shown in figure 17.
Being the preferred embodiments of the present invention only below, is not that for a person skilled in the art, the present invention can have various modifications and variations for restriction the present invention.All any modifications of making within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
