Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described, but embodiment of the present invention is illustrative, instead of determinate.
Fig. 1 is a kind of flow chart being embedded with the variable information printing data generating method of the word character library of information.
As is shown in fig. 1: the variable information printing data generating method being embedded with the word of information is made up of four steps.
First, in the step reading printing position information, read and comprise tax reciept, commodity sign is in the interior information will printing the relevant variable information printing position of the printing images of variable information or data.The printing images of printing variable information, is generally the printing images that will be realized by common non-variable information printing-flow.Before printing variable information, this printing images is completed for printing by common non-variable information, anti-electric point that will propose below, and anti-printing of scratching the camouflage color dot matrix of picture also will complete in this operation.
When printing variable information, the variable information printing position in the view data of common non-variable information printing, the relative position between printed data will in the form of images, or the form of data is imported in the composing system of variable information printing machine.
Here, be not limited only to the printing images of tax reciept, commodity sign, every all printing images printing variable information that need all can be included.
Secondly, in the step reading variable information code, read customer-furnished variable information code data, these data are generally 12 decimal datas, the main number representing tax reciept, the attribute of commodity, build date, manufacturing location, permitting sale place, and the specific information of user etc., variable information can also be encrypted by computer.
Here be not limited to the variable information of numeral, also can be Chinese character, Roman capitals or symbol etc., can comprise all words.
Next, in the text transform step being embedded with information, according to the numerical value of variable information, from in the word character library of the information that is embedded be arranged in advance operating system, read the character image of the information that is embedded with, by this image configurations on fixed printing position, generate a printed data for above-mentioned variable information.
Finally, judge whether the process of all variable information codes all completes; Otherwise return second step; That the generation being embedded with the variable information printed data of the word of information completes.Because the word being embedded with information occurs with the form of character library, code-spraying printer or printer can process according to the form of word, therefore will be installed in code-spraying printer or printer above by the whole printed data after 4 step process, just can realize the variable information printing of the word of the information that is embedded with at a high speed.
The word being embedded with information can carry out the printing of variable information in the composing system of code-spraying printer or printer by the word of the information that is embedded with of character library form, can also by the mode of virtual printer, on the driver of printer, the driver of a virtual printer is installed, the driver of this virtual printer is connected code-spraying printer or printer by program, a printing images just can be obtained from the driver of code-spraying printer or printer, in this printing images, according on the position that user specifies, the character image of the be embedded with information relevant to variable information is sticked, then, be sent to code-spraying printer or printer enforcement printing again or print, repeat above-mentioned operating process, finally just can realize the printing to whole variable information or printing.
The printing being embedded with the variable information of the word of information can also adopt the method covering printing (Overly Print), namely on the position that user specifies, by the overall printing image that the character image of the be embedded with information relevant to variable information sticks, be placed in the code-spraying printer or internal memory specified by printer having and cover printing functionality, code-spraying printer or printer are automatically by this printing images and tax reciept, the packing of product or label printing image carry out covering printing, repeat above-mentioned operating process, finally just can realize the printing to whole variable information or printing.
The printing of variable information can also adopt the method for directly printing, namely by program at same tax reciept, the variable information printing position of the printing images of the packing of product or label, often add variable information data, and on the character image position of the be embedded with information relevant to variable information, the view data often sticking the word of a be embedded with information relevant to variable information is just sent to code-spraying printer or printer, implements printing or prints, until the printing of whole variable information or be completed for printing.
Fig. 2 is a kind of flow chart being embedded with the recognition methods of the variable information printing images of the word of information.
As shown in Figure 2: a kind of recognition methods being embedded with the variable information printing images of the word of information is made up of three steps.
First, be embedded with in the step of the character image of information in reading, by comprising scanner, CCD, CMOS reads at any one interior imageing sensor with the form of character library, the character image of the form of view data or the printed information that is embedded with on print media of the form of vector data.
Here, the receptible spectral characteristic of sensor, and the spectral characteristic of illumination can be ultrared, can be luminous ray, also can be ultraviolet light.Can be a kind of spectral characteristic, also can be the spectral characteristic of plural number.
The above-mentioned computer graphical code showed with the written form being embedded with information is with the form of character library, image format, and wherein a kind of form of vector form shows.
Finally, be embedded with in the step of the literal value of information in display or output, display or output are embedded with the code value of the word of information.Whether user is consistent with the data on tax reciept or antifalsification label by observing the data after being embedded with the character identifier identification of information, thus just can differentiate whether this tax reciept or antifalsification label are real.
Identifier is when identification is embedded with the word of information, general employing infrared illumination, infrared imaging sensor carries out identifying, main consideration adopts the ink of carbon containing or ink powder or transparent infrared ray absorbing ink etc. to print to the word being embedded with information, these printed materials are utilized to have characteristic to infrared ray absorbing, and the characteristic of CMY Color pair infrared ray projection, thus, the word being embedded with information can be imbedded in coloured image.When adopting thermal printer printing, due to not carbon containing in the image that thermal printer prints out, therefore can not identify with infrared ray identifier, the image recognizer of visible ray therefore can be adopted to identify.In order to carry out the application of higher levels of false proof invisible-bar-number, can also the ink of different spectrum or ink powder be taked respectively to print from positioning datum point the information point being embedded with the word of information.When identifying, taking the alternately illumination of different spectrum, respectively information point and positioning datum point being extracted out and carrying out entirety and identify.
The character library realizing being embedded with the word of information in the literature by increasing some dot matrix that the present invention proposes, the distribution of its dot matrix can consider have following several distribution to realize.
Information imbeds the schematic diagram that dot matrix is the different many bit informations of directional spreding logger computer by dot matrix, as shown in Figure 3: the dot matrix be embedded with in the word of information that site 301 is made up of information point 302 and 303, different information is represented according to the different directions that information point 302 and 303 is formed.
In figure 3, figure a can represent information 0, and figure b can represent information 1, and figure c can represent information 2, and figure d can represent information 3.Be embedded with the word a of information, b, c, d obviously can regard as by different directions and different Electromagnetic Wave Propagation directions, and different Mechanics Vector results realizes computer many bit informations record.
Fig. 4 schematic diagram that to be the dot matrix be embedded with in the word of information be by the different many bit informations of graphic recording computer.In the diagram, figure a can represent information 0, and figure b can represent information 1, and figure c can represent information 2, and figure d can represent information 3.
Fig. 5 is the dot matrix be embedded with in the word of information is by the schematic diagram of concentrated site with the word of the information that is embedded with of disperseing site to form.As shown in Figure 5, all printing points in a site are formed the example that a dot matrix concentrated site a formed and the spaced point b having at least a site disperseed to form form the fine roots can imbedding information.Concentrated site a is set as the value of information " 1 ", and dispersion site b is set as the value of information " 0 ".On the contrary, concentrated site a can be set as the value of information " 0 ", dispersion site b is set as the value of information " 1 ".
In addition, in order to form standard dot pattern, as shown in Figure 5, the high H of point 501 of concentrated site a
50as the diameter value of two printing points (the minimum printable size of printer), the width W of the point 501 of concentrated site a
50as the diameter value of a printing points.The point 502 of dispersion site b only plays the effect of shading gray scale homogenization, is not used in identification, the height H of the point 502 of dispersion site
51with width W
51all as the diameter value of a printing points.The height of site is H
52, width is W
52.
As shown in Figure 5, concentrated site a can be regarded as amplitude modulation mode and AM screen, dispersion site b is regarded as mode of frequency regulation and FM screen.Namely recorded information can be carried out according to the different dot pattern of modulation system.
In addition, because concentrated site a can be regarded as low frequency number site, dispersion site b regards high-frequency number site as, so concentrated site a and dispersion site b are according to the composition recorded information of different frequency number.
And then concentrate the gray value of each site of site a large, the gray value of each site of dispersion site b is little, thus alternatively concentrate site a and dispersion site b be for a point different gray values carry out recorded information.
In other words, concentrate the size of the point of site a large, the size of each point of dispersion site b is little, so concentrated site a and dispersion site b carrys out recorded information according to the dot pattern varied in size.
About above content, a lot of meanss of interpretation can also be had.If but identical with above dot pattern, all belong within scope of the present invention.
To be the dot matrix be embedded with in the word of information be Fig. 6 by information point realizes the schematic diagram of computer many bit informations record according to the result of different positions and phase-modulation.As shown in Figure 6: figure (a) can represent information 0, figure (b) can represent information 1, figure (c) can represent that information 2 and figure (d) can represent information 3, and figure (e) and figure f can represent positioning datum information.
In addition, Fig. 7 is the given word site 701 being embedded with information shown in Fig. 6, by a that the some transmitting signal of the physical phase-modulation of the difference of information point 702 (PM) is formed, the schematic diagram of the result of b, c and d tetra-kinds of outs of phase modulation (PM).
The derivation of the Mathematical Modeling of the dot pattern be made up of phase-modulation shown in Fig. 6 and Fig. 7 is as follows.
If the function of the dot pattern be made up of the square lattice of interval T is ζ (x, y), then ζ (x, y) be standardized after result as follows:
Here, the signal response function for the dot pattern of phase-modulation is:
η(x-i×T，y-j×T)＝η(m×T，n×T)
The level m be standardized, and the centre coordinate value of the point of vertical n-th dot pattern is
(m × T, n × T), the displacement function of each relative centre coordinate (m × T, n × T) of dot pattern is [ε (m, n), δ (m, n)] in addition, and so, the set D of dot pattern is as follows:
η(m×T，n×T)＝η{ε(m，n)×T，δ(m，n)×T}+η{[1-ε(m，n)]×T，[1-δ(m，n)]×T}+…+η{[∞-ε(m，n)]×T，[∞-δ(m，n)]×T}+η{[1+ε(m，n)]×T，[1+δ(m，n)]×T}+…+η{[∞+ε(m，n)]×T，[∞+δ(m，n)]×T}
Namely
{[m×T+ε(m，n)×T]，[n×T+δ(m，n)×T]}∈D
Thus, input and signal is replied function η { [i+ ε (m, n)] × T, the phase-shifted amount ζ after [j+ δ (m, n)] × T} brings into
m-i, n-joutput signal be:
Here, control ε (m, n) and (m, n), just can realize for the transmitting signal { phase-modulation of ζ m, n}.

Figure 15 is the schematic diagram of the word of the information that is embedded with realized by different colours method on stroke.As shown in figure 15: 1500 is examples of the word of the information that is embedded with realized by stroke bar code method, on the stroke being located at word 1501 namely 1502 to 1509 8 stroke positions on, k kind color can be coated, the information of (k-1) × 8 bit can be represented.In like manner, on the stroke being located at word 1501 in fig .15 namely 1502 to 1509 8 stroke positions on, the different gray scales of control k kind stroke, can represent the information of (k-1) × 8 bit equally.
Imbed information in the literature, also by digging the method for the method representation information of circle in strokes of characters, by the end points at strokes of characters, crosspoint, object that the information of realization imbeds etc. is carried out processing in the place such as joining, but, said method there will be processing method for different words, imbeds the difference of information content etc., is not therefore suitable for the requirement imbedding identical information for a word, here, just do not describe one by one.
Figure 16 is the schematic diagram that the color region utilizing RGB color space and CMYK color space to convert realizes anti-counterfeit printing.The color space that general scanner uses is RGB form, and the color space that printing machine uses is CMYK form.As shown in figure 16: if color selecting is in the color region of RGB/CMYK, the image gone out printed by it can be copied faithfully by scanner and print out, and namely this color region is reproducible region.Again as shown in figure 13: if select the image gone out printed by RGB color region or CMYK color region can not be copied faithfully by scanner.Utilize such principle can realize the effect of anti-counterfeit printing.Such as, be embedded with the color selecting K version of the word of information, the image become by CMY tri-colour cell can be printed on the word being embedded with information, and for example the color of image of fruit CMY tri-colour cell one-tenth is darker, the actual composition with black, but due in the color of image that becomes by CMY tri-colour cell not containing carbon, be transmission to infrared ray, therefore do not affect the recognition of the word of the information that is embedded with of K version.But, if above-mentioned image is copied by scanner, printed by the image that goes out, the originally color of image with the composition of black of CMY tri-colour cell one-tenth, will be reflected in K version when point version, clash with the word of the original information that is embedded with in K version, therefore correctly can not read the word of the information that is embedded with in K version, thus reach false proof effect.
Figure 17 is the schematic diagram of the word of the information that is embedded with security feature.As shown in figure 17: 1701, for being embedded with the word of information, are provided with information dot matrix 1703 around word 1702, and camouflage color dot matrix 1704, dot matrix 1705 is located.According to the RGB color space of Figure 16 and the conversion characteristics of CMYK color space, if reader is ultrared, then information dot matrix 1703 black and the K version of carbon containing, or the transparent ink printing to infrared ray absorbing, the Dark grey printing to infrared transmitting that camouflage color dot matrix 1704 mixes with CMY.When reading with IR-reader, information dot matrix 1703 is visual dot matrix, can clearly be read, and camouflage color dot matrix 1704 is not visible dot matrix, can not be read by IR-reader.When the word 1701 being embedded with information is read into RGB electronic image by high accuracy scanner, information dot matrix 1703 and camouflage color dot matrix 1704 are read as a kind of color, all be divided into K version by the information dot matrix 1703 after CMYK point of version with camouflage color dot matrix 1704, the word printed out just loses information.Thus serve the effect of anti-scanning anti-copying.As the form of word character library, the printing with the word of the information that is embedded with of security feature of Figure 17, needs use two character libraries, and namely Figure 11 is a character library, camouflage color dot matrix uses another character library, carries out the word with the information that is embedded with of security feature that twice printing synthesizes Figure 17 respectively.
Figure 18 is the schematic diagram that another kind has the word of the information that is embedded with of security feature.As shown in figure 18: 1801, for being embedded with the word of information, are provided with information dot matrix 1803 around word 1802, and following at word 1802, the right is provided with 10 location dot matrix 1804, and the location dot matrix stain of reality represents.Relative 10 the location dot matrix 1804 of information dot matrix 1803, can be arranged on the position of drawing a circle of 0 to 9, can represent 0 to 9 information respectively.Here, information dot matrix 1803, on the position of 5, can represent numerical value 5.RGB color space according to Figure 16 and the conversion characteristics of CMYK color space, by information dot matrix 1803 black ink of carbon containing or ink powder printing, 10 location dot matrix 1804 are with to the black ink of infrared transmitting or ink powder printing.As the form of word character library, the another kind of Figure 18 has the printing of the word of the information that is embedded with of security feature, also use two character libraries are needed, namely Figure 11 is a character library, camouflage color dot matrix uses another character library, carries out the word that another kind that twice printing synthesize Figure 18 has the information that is embedded with of security feature respectively.
When identifying that the another kind shown in Figure 18 has the word of the information that is embedded with of security feature, by the switching of infrared illumination and visible illumination, read the information dot matrix 1803 under infrared illumination respectively, and the location dot matrix under visible illumination, under normal circumstances, information dot matrix is point version printing under an image with location dot matrix, therefore, strict positioning relation is maintained between information dot matrix and location dot matrix, when illegal person reads by the scanner of infrared camera and visible ray the word that the another kind shown in Figure 18 has the information that is embedded with of security feature respectively, and copy the word 1805 of the imitated information that is embedded with, cause is the image read under different equipment, the information point 1807 of the surrounding of the word 1806 after imitated, and the positioning relation between anchor point 1808 is just destroyed, therefore reader is easy to judge that the word 1805 of the imitated information that is embedded with is false.
Here, the switching not only can using infrared ray and visible ray is read, infrared ray and ultraviolet, and visible ray and ultraviolet etc. all can realize above-mentioned effect.The illumination of reader and the spectral characteristic of imageing sensor not only can adopt two kinds three kinds even manyly also can.Not only utilize ink or the absorption of ink powder to certain spectrum and the characteristic of transmission, ink or ink powder also can be utilized the fluorescent characteristic of certain spectrum, light-reflecting property, polarized light property etc.
