Detailed description of the invention
In the present invention, for human eye, lens coding 1 will be called by supplementary means with regard to unrecognizable conceal subject 3.In addition, in Fig. 5-5e and Figure 11-15, illustrate lens coding 1.After this application of the decoding film being configured to lens-shaped film 20, theme 3 is visible for human eye.Theme 3 can be single theme 4 of such as single letter, or the theme 3 that jointly can be made up of multiple single theme 4, a such as word.
Fig. 1 a shows alphabetical K in common standard character figure, but but greatly amplifies.Be in the embodiment making single theme 4 (in this case alphabetical K) be difficult to identify of this application and description, with single background line grid 5, the background of single theme 4 filled completely according to Fig. 1 b.Single background line 5a remains dark colour, forms straight line and arranged in parallel.They all have identical line strength b, and adjacent single background line 5a is until single motif area has identical distance between centers of tracks d each other all the time.Single theme 4 is given prominence to from single background line grid 5.Single theme 4 own coverlet theme line grid 6 is filled completely.Single theme line grid 6 has the single theme line 6a be installed in parallel with each other, and they also have identical distance between centers of tracks d each other simultaneously, and this identical distance between centers of tracks d is as the lines 5a of single background line grid 5.Single single theme line 6a of theme line grid 6 and the line 5a of single background line grid 5 are along its total length having identical to each other and constant separately line strength b.But single theme line grid 6 staggers with half distance between centers of tracks 2/d compared to single background line grid 5 in the vertical direction of line 5a, the 6a with two grids 5,6.Distance between centers of tracks d is single background line grid 5 and the average headway of the adjacent lines of single theme line grid 6, and it is consistent in whole alphabetical printed words scope.
Letter in Fig. 1 a is called the standard character of standard font.Character in Fig. 1 b is called the lens-shaped letter 7 of lens-shaped font.
Lens-shaped letter 7 (in this case alphabetical K) still can identify for human eye very well according in the size of Fig. 1 b, but when lens-shaped letter 7 reduces further, it can thicken fast.If distance between centers of tracks d reduces relative to the resolution ratio of human eye, then single theme 4 of lens-shaped letter 7 just no longer identifiable design in Figure 1b.The resolution ratio of eyes is approximately 80 μm in the distance of 25cm.Following distance between centers of tracks d and line strength b selected in character for lens-shaped font, and namely line width is at 42 μm ± 10 μm, and be preferably 42 μm or less, similarly, distance between centers of tracks is at 170 μm ± 10 μm.Therefore, line width and distance between centers of tracks close to resolution of eye, so can only very difficulty identify.
In order to make to be hidden in single theme 4 in lens-shaped letter 7 can with eye recognition out, will the decoding film of lens-shaped film 20 form be used.Lens-shaped film 20 is placed on above lens-shaped letter 7.Fig. 2 summary illustrates described setting.Lens-shaped film 20 have be set parallel to each other, in whole Fig. 2 perpendicular to the banded lens-shaped lens 21 that extend on the length direction L of the lens-shaped film 20 of display surface trend, they have the arc line shaped of lens sample in the cross section perpendicular to length direction L according to Fig. 2.Can banded lens-shaped lens 21 be introduced in the lens-shaped film 20 for visible ray substantially transparent, thus when being placed on lens-shaped letter 7 by lens-shaped film 20, lenticular lenses 21 is approximately separated by with the size of lens-shaped lens 21 focal length and the lens-shaped letter 7 printed from the teeth outwards.
Fig. 2 illustrates the line strength b of the line according to Fig. 1 b.The line strength b of each single theme line 6a and single background line 5a is identical in whole line length and for every bar line 5a, 6a.Line strength b is 42 identical to 85 identical, preferred b=42 μ=and, therefore it is lower than the resolution ratio of eyes.In the present embodiment, the distance between centers of tracks d=170 of adjacent single theme line 6a is in eye.Fig. 2 b illustrates five single theme line 6a and of single theme 4 and moves in parallel d/2=85 in single single background line 5a of m relative to single theme line 6a.
Lens-shaped film 20 has 150lpi (OK/inch) at this, and the lens cycle of this and 170 μ 7 matches, and obtains distance between centers of tracks d=170 phase thus.Only can there is single theme line 6a according to conciliation or only can there is background line 5a under lens-shaped lens 21 thus.There is single theme line 6a for 21 times in lens-shaped lens in fig. 2.The spacing of single background line 5a and single theme line 6a is d/2=85 coupling according to Fig. 2.
If in the present embodiment with 600dpi printer print wire 5a, 6a, it is wide that each point has the point of about 42 points, thus not only the line strength b of single theme line 6a but also single background line 5a should be respectively b=42 institute so that b=85 so.
When being observed lens-shaped letter 7 by lens-shaped film 20, the background line 5a of observer's (not shown) only visible single background line grid 5 under the adjustment that lens-shaped film 20 is correct, or single theme line 6a of only visible single theme line grid 6.The correct adjustment of the lens-shaped film 20 on the lens-shaped letter 7 printed in the plane realizes by rotating lens-shaped film 20 on lens-shaped letter 7 simply.
Fig. 3 a schematically illustrates the lens-shaped film 20 on lens-shaped letter 7.The distance between centers of tracks d of the lens of lens-shaped film 20 both also matched with the distance between centers of tracks of theme line grid 6a with background line grid 5a.Show the lens-shaped lens 21 of lens-shaped film 20 in fig. 3 a by a dotted line.But also can not find out the effect of lens-shaped film 20 in fig. 3 a.
Shown picture is that observer provides the truth be placed on by lens-shaped film 20 on lens-shaped letter 7 in fig 3b.Observer only can see the single theme line 6a be located immediately at below lens-shaped lens 21 when correct adjustment lens-shaped film 20.Single background line 5a remains on hidden state by lens-shaped film 20.By the effect of lens-shaped film 20, between single theme 4 and background, create the contrast significantly improved compared to lens-shaped letter 7, thus single theme 4 is discernible for observer.
Fig. 4 a and 4b all show lens-shaped letter 7, is lens-shaped font in fig .4, in fig. 4b for revealing process lens-shaped font.
The further obfuscation of single theme 4 " K " identifiability is obviously shown in the direct relative position of lens-shaped letter 7 with the lens-shaped letter of revealing process.Relative to the lens-shaped letter 7 according to Fig. 4 a, on lens-shaped letter 7, be placed with random dot pattern.Selection random dot pattern like this, namely puts and have different length on the length direction L of single theme line 6a and single background line 5a, and is set to contact with line 5a, 6a separately.
Fig. 5 a to 5e illustrates the photo of lens coding 1 with the form of four lens-shaped letters 7 printed continuously.Single theme 4 forms alphabetical K here respectively.Can also produce such theme 3, selecting during other letters can be significant word, coding or like this.
Single lens-shaped letter 7 is applicable as the letter of lens-shaped font, is preferably font (Font), preferred TrueType font (.ttf).Lens-shaped font can store easily or copy as other fonts (Arial, Calibri etc.) on business computer or printer.Because the letter of lens-shaped letter 7 as lens-shaped font is used, so can with very simple, economical and timesaving mode prints the almost each arbitrary lens coding with different lexicographic order and numerical order.
Single background line grid 5 and single theme line grid 6 of the single lens-shaped letter 7 of lens-shaped font are identical, thus when printing multiple lens-shaped letter 7 continuously according to Fig. 5, single background line 5a of single background line grid 5 for single single background line 5a just in time dislocation-free and cross in single background line 5a of adjacent lenticular shape letter 7 with identical line strength b.Single theme line 6a of single theme 4 equally just in time crosses in single theme line 6a of adjacent lenticular shape letter 7 on its imagination extended line.The word, coding etc. that are made up of the lens-shaped letter 7 printed successively can be identified thus by an adjustment lens-shaped film 20.
Fig. 5 b illustrates in Fig. 5 one that has in the thick lens-shaped letter 7 of d/4 line, and wherein d still conforms to the lens cycle at this, namely conforms to the spacing of the lens-shaped lens 21 of lens-shaped film 20.
Fig. 5 c illustrates in Fig. 5 the lens-shaped letter 7 with overlapping random dot pattern.
Fig. 5 d illustrates in Fig. 5 b the lens-shaped letter 7 with the overlapping random dot pattern being different from Fig. 5 c.
Fig. 5 e illustrates in Fig. 5 b to have and is less than the thick letter of d/4 line.This illustrates particularly by overlapping with random dot pattern of lens-shaped letter 7, even if for the identifiability of human eye in the state of obviously amplifying according to Fig. 5 c and 5d, compared to Fig. 5 b and 5e or reduction.
Fig. 6 illustrates the alphanumeric arrangement that Fig. 5 to 5d has the good lens-shaped film 20 of adjustment.Lens-shaped film 20 is placed on the lens coding 1 that is made up of four lens-shaped letters 7 and on three single lens-shaped letters 7, and through adjustment.The identifiability of four single themes 4 " K " in Fig. 5 will be significantly improved by lens-shaped film 20.In fact, the single theme 4 " K " in Fig. 5 original size only or almost can not can not be identified with human eye.Fig. 5 c and 5d shows by lens-shaped letter 7 and the superposing of random dot pattern, although be hidden in background by darker for theme 3, but can reduce the cost of identifiability with lens-shaped film 20 after decoding.As Fig. 5 c and 5d to have in the situation covering lens-shaped film 20 the contrast shown, identifiability highly depends on the type of selected random dot pattern here.
The symbol that Fig. 7 to 10 shows these standard characters be stored in traditional computer such as such as Arial, Calibri etc. with explanatory view first in the figure 7 presents.Single letter is generally stored as font at this.Font is typically configured to the font based on vector, such as, be TrueType font,
general down take .ttf as EOF.Font (i.e. the summation of single letter and numeral and bitmap) can store in principle, but there will be convergent-divergent problem.In contrast, be the file based on vector by the single letter of TrueType font and stored digital, thus when mitigation and amplification letter, produce when namely printing with 11 pounds, 12 pounds, 14 pounds etc. and there is no smooth edges
or the printed drawings picture of sawtooth.The meticulous lines of such as serif and so on are especially suitable for printing as TrueType font storage, and for the break-even displaying of milli and the letter and number printing arbitrary dimension.
In addition, in order to improve the print quality of printed drawings picture, most of printer has the image editing function be integrated in driving or hardware.Described image editing function is difficult to or can not closes completely.In order to avoid the lines that Built-in Image editting function is level and smooth meticulous especially, lens-shaped letter 7 is converted to font.Even very little font size, when printing lens-shaped letter 7 also and do not rely on the resolution ratio of printer and obtain good printing effect equally.Lens-shaped letter 7 is converted into font especially can also show change absolute coding with enough speed, and is that series printing is ready.Be converted into font also for seamlessly forming lens-shaped letter 7 successively on same height.In the printed drawings picture of letter, there will not be dislocation, this requires the follow-up adjustment of decoding film 20.
Fig. 8 illustrates the single lens-shaped letter 7 of lens-shaped font in explanatory view.The concept of font is also relevant with numeral, additional character at this.
Fig. 9 display has the lens-shaped letter 7 of Fig. 8 lens-shaped font of overlapping random dot pattern.
Figure 10 display has the lens-shaped letter 7 of Fig. 8 lens-shaped font of overlapping random sectional hole patterns.Overlapping not by means of only with random dot pattern of each lens-shaped letter 7, also by the overlapping identifiability reducing single lens-shaped letter 7 further with random sectional hole patterns.
Figure 11 to 15 shows the different embodiments of safety label 41.Each safety label 41 has lens coding 1, and it has multiple lens-shaped letter 7 formed by theme 3.Figure 11 shows three adjacent safety labels 41 separately respectively with lens coding 1 schematically shown, and its theme is being unrecognizable for human eye.
Figure 12 display has the safety label 41 in the Figure 11 covering the rear lens-shaped film 20 of calibration.The absolute coding of single safety label 41 is discernible.In the present embodiment, coding is serial number, realizes checking by reading sequence number 40.
Figure 13 display covers the safety label 41 of lens-shaped film 20, and wherein, absolute coding is visible.According in the embodiment of Figure 13, absolute coding is random and rare, and that is, the sequence number 40 only having some to determine is effective.Effective sequence number 40 will be stored in database, thus when verifying product, read lens coding 1 to recognize sequence number 40, and compared by the sequence number in itself and database by lens-shaped film 20.When the sequence number 40 identified stores in a database, so product then turns out to be very.Otherwise it is related to fakement, therefore have the additional safe practice except the safety label 41 of Figure 12.
That Figure 14 display has a random equally and rare coding and be coated with the safety label 41 of lens-shaped film 20, wherein, sequence number 40 is hidden in lens coding 1, and is printed on safety label 41 using form expressly as sequence number 42.Realize checking by the sequence number 40 of sequence number 42 relatively expressly and lens coding 1.
Figure 15 display has lens coding 1 and is coated with the safety label 41 of lens-shaped film 20 equally.The absolute coding of lens coding 1 is visible 20 times at lens-shaped film.Absolute coding is random equally.Some of only encoding determine that sequence number 40 is effective.Ordered sequence numbers 40 is stored in database.Other additional codings are printed on safety label 41 with form expressly.This coding is also random and rare.The sequence number 42 more only determined is effective, is also stored in a database.The combination of these two codings also stores in a database in addition.By realizing verifying with comparing of database.
