An implementation process of this method:
1), get screening forme computer data, be the part enlarged drawing of screening forme computer data one edition as I, Fig. 2, Fig. 3, Fig. 4, Fig. 5 of Fig. 1.Screening forme computer data can be the screening forme data that describe in words, as data such as PS, EPS.
2), specify the position that on screening forme computer data, to bury data message, as 1. 2. 3. 4. 5. indication position of the I of Fig. 1; Burying the position of data message can directly be specified by the user, also can specify by algorithm, the position that need bury data message can be on a version, if multiple printing, the position of data message is buried in appointment can be on many editions, if printed matter needs C, M, Y, K four editions to print, the user can specify the position of burying data message on any one edition, also can be on any two editions assigned address; Also can be at any three editions assigned addresses; Also can be at four version assigned addresses; Bury the position of data message and also can calculate by algorithm, as Fig. 6, X=X
0+ (POS%3) * 100, Y=Y
0+ (int) (POS/3) * 80, wherein POS is which position that is used to bury data message, X, Y are the coordinate of which position, X
0, Y
0Be side-play amount, (int) for rounding, the adjacent transverse location interval of data message is buried in 100 expressions, and the every row of 3 expressions is specified 3 positions, and the every capable lengthwise position of 80 expressions at interval.As be used to bury first position POS=0 of data message, calculate X=X
0+ (0%3) * 100=X
0, Y=Y
0+ (int) (0/3) * 80=Y
0, i.e. the POS1 position of Fig. 6; Bury second position POS=1 of data message, calculate position X=X
0+ (1%3) * 100=X
0+ 100, Y=Y
0+ (int) (1/3) * 80=Y
0, i.e. the POS2 position of Fig. 6; Bury the 3rd position POS=2 of data message, calculate the position at X=X
0+ (2%3) * 100=X
0+ 200, Y=Y
0+ (int) (2/3) * 80=Y
0, i.e. the POS3 position of Fig. 6; Bury the 4th position POS=3 of data message, calculate the position at X=X
0+ (3%3) * 100=X
0, Y=Y
0+ (int) (3/3) * 80=Y
0+ 80, i.e. the POS4 position of Fig. 6; The 4th position of promptly burying data message is since second row ... in a word, the user specifies the position of burying data message to be specified or to be calculated or the part position is specified by the user with algorithm by the user on each edition, part is calculated by algorithm, but the user specifies or need note with the position of burying data message that algorithm is calculated, positional information is provided during for identification, all bury the position of data message and the information of this place, position version calls position version data group this record for we, and one group of data wherein are called position version coordinate.As the I of Fig. 1 1. 2. 3. 4. 5. indication position version data group be (x1, y1,1) (x2, y2,1) (x3, y3,1) (x4, y4,1) (x5, y5,1), x1 in the position version coordinate here, y1; X2, y2... represents the position, 1 in the version coordinate of position is illustrated on No. 1 version; If many editions, the symbol of the version that the user can own desired location version coordinate place represents with C that as the C version M version is represented or the like with M;
3), the data of representing with the form that changes the user specifies or algorithm is calculated position or near the site it of burying data message.Suppose that the user has set form 1,2, the 3...N of N kind site, the user can change into form 2 representatives to the form of a certain assigned address site and bury 5 of data message, for example change into 7... that form 4 representative buries data message, as Fig. 1 II originally form for the circle solid dot, 1. locate to change over the empty forms registration according to 0,2. locate to change over gauze point expression data 1,3. locate to change over the site that has random noise point and represent data 2,4. locate to change over several sites on every side and remove some sites, increase a site in this position again and represent data 3; 5. locate to change over the triangle site represent data 4... therefore as Fig. 1 I change over that to represent to bury the data message that data 01234... buries if desired as Fig. 1 II be that 32410... represents as the some form of 4. locating of Fig. 1 II in first position usefulness of user's appointment so; Second position is with representing as the some form of 3. locating of Fig. 1 II; The 3rd position is with representing as the some form of 5. locating of Fig. 1 II; The 4th position is with representing as the some form of 2. locating of Fig. 1 II ... also can represent the different data of imbedding at the some homomorphosis of specifying the diverse location place to change over, key is seen the rule of user representing data, such as: user's definition rule is to change over the empty forms registration according to 9 in the site of first position, change over the empty forms registration according to 3 in the site of second position, changing over the data that the empty forms registration imbeds so if desired according to 7... in the site of the 3rd position is that 937... changes into blank in first site, position of position data group so; Blank is changed in site, second position; Blank is changed in the 3rd site, position ... we expand the position version coordinate item in the version data group of position once, expand to (X, Y, BN, T2, NUM, EMBEDPOS), X wherein, Y represents to specify the position coordinates that buries data message, and BN represents to specify the position coordinates that buries data message on which version, and T2 represents the form after the change of the position coordinates place that specifies or calculate or near site, NUM is which numeral that the site represents to bury data when changing into T2, and EMBEDPOS is the position of NUM numeral in burying data message.We (X, Y, BN, T2, NUM EMBEDPOS) is called expanding location version coordinate, the array of being made up of all expanding location version coordinates is an expanding location version coordinate array.Therefore the user according to the data of burying data message, these data in burying data message the position and the embedding location that the user specifies or algorithm is determined determine expanding location version coordinate array, in screening forme computer data, imbed the site form of the data message correspondence that needs bury then according to expanding location version coordinate array, so promptly obtained each edition of the data message that buries.Each edition gone out the film, printing down, print or print to undertake the printing of becomes printed matter on the medium.Expanding location version coordinate X, the result of the site form of Y place or near change can not change local gray scale substantially, though as 2. having changed shape among Fig. 1 I, the II, local gray scale is constant substantially, makes last print quality constant substantially; Also the result of the site that can change changes local gray scale, as among Fig. 1 I, the II 1. by there being the site to change over no site, print quality is changed to some extent.
4), to the identification of the data message of the printed matter that buries data message.At first with apparatus for picking-up image printed matter is absorbed image, the expanding location version coordinate array when originally imbedding data message according to the user is discerned absorbing into image, is about to the X of BN version, and the T2 of Y position identifies and be construed to digital NUM.All NUM have discerned the back and according to expanding location version coordinate array NUM have been put into the EMBEDPOS position and just can be reduced into the data message originally imbedded.
5) though above scheme is to be the scheme that AM screening forme computer data buries computer data information by amplitude modulation, this method is applicable to that also frequency modulation is that the information of the screening forme computer data that mixes of FM or AM, FM is buried simultaneously.
Below we are bright for instance:
Suppose that we have 8 data 87654321 will imbed chromatograp, suppose Fig. 2,3,4,5 for we need bury four editions of data, we specify in and bury two data 87 on Fig. 2 version, and 1 position is point on Fig. 2 version
According to 8,8 in first position of burying data message, 2 position is point on Fig. 2 version with blank substitution list registration
Represent data 7,7 in second position of burying data message, so at the expanding location version coordinate of C version be ((Cx1, Cy1, C,
, 8,1), (Cx2, Cy2, C,
7,2)) on Fig. 3 version, bury 3 data 654, the version expanding location version coordinate be ((Kx1, Ky1, K, →-, 6,3), (Kx2, Ky2, K, →, 5,4), (Kx3, Ky3, K, →, 4,5)), in like manner on Fig. 4 K version, bury 1 data 3, the expanding location version coordinate of Fig. 4 K version is (Mx1, My1, M
, 3,6) on Fig. 5 version, bury two data 21, the expanding location version coordinate of version be ((Yx1, Yy1, Y,
, 2,7), (Yx2, Yy2, Y,
, 1,8)); Cx, Cy; Kx, Ky; Mx, My; Yx, Yy represent each edition position coordinates, according to expanding location version coordinate array ((Cx1, Cy1, C, →, 8,1), (Cx2, Cy2, C,
, 7,2)) ((Kx1, Ky1, K, →-, 6,3), (Kx2, Ky2, K, →, 5,4), (Kx3, Ky3, K, →, 4,5)), (Mx1, My1, M,
, 3,6), ((Yx1, Yy1, Y,
, 2,7), (Yx2, Yy2, Y,
, 1,8)) change original Fig. 2,3,4,5 each edition data, obtain Fig. 7,8,9,10 each edition data, go out film sheet then, printing down is printed to such an extent that printed matter is our needed printed matter.During identification, printed matter is scanned into image, finds the position of burying data message, legacy data is restored in conjunction with expanding location version coordinate array.
