Description

The method of making implicit pattern during printed matter plate-making

Technical field

The plate-making picture that the present invention relates to printed matter is handled, and makes implicit pattern when especially relating to printed matter plate-making or method of encrypting on printed matter.

Background technology

Adopt site or netting twine to form in the existing printing technology and show various patterns as base unit; And colored printing generally is to make up or adopt special look by the site (or netting twine) of C, M, Y, four kinds of colors of K; Show shades of colour and pattern; The difference angle of C, M, three kinds of colors of K is 30 degree, and the Y version can differ 15 degree on one of them angle of C, M, K.The standard angle of C, M, Y, four kinds of colors of K: C is that 75 degree, M are that 45 degree, K are that 15 degree, Y are 90 degree during general now the printing, except the Y version, and C, M, the equal changeable angle of K.This characteristic of printing technology capable of using with the plate-making of plate-making software the time, is made implicit pattern (literal or image) and encryption on image to be printed.The method that image is transferred to the site, makes implicit pattern is arranged in the prior art, make the printed matter that has implicit pattern or encryption, can be equipped with testing tool, be used as and encrypt and security purposes.But, because there is the site regular, as long as obtained printed matter; Understand dot density, just can make a testing tool, find out the pattern of being hidden one by one; Do according to above or other method then hiding, just can be pirate, so; This area has the people of equivalent technology to make again and adds implicit pattern, crack and piracy, so the method antifalse effect of background technology is good inadequately.And such printed matter sees that the significant degree of implicit pattern can only reach 50% after adding testing tool, and is clear inadequately, and National People's Congress's activation of twenty-twenty vision is differentiated, and it is fuzzy that people older or that have defective vision seems to feel.Shown in Fig. 3 A, be the printed matter that is manufactured with implicit pattern of background technology, the enlarged image of when not adding testing tool, seeing is the enlarged image of when Fig. 3 A has added testing tool, seeing shown in Fig. 3 B, " just " word among the figure is false proof hiding pattern.

Summary of the invention

The method of making implicit pattern when the technical matters that the present invention will solve provides the plate-making of a kind of printed matter, the printed matter that further obtains after this method plate-making add behind the relevant detection instrument can be very obviously be clear that implicit pattern and as encrypting, be difficult for being cracked during anti-fake effect and pirate.

For solving the problems of the technologies described above, the method that the present invention makes implicit pattern when providing a kind of printed matter to make a plate is characterized in that, comprises the steps:

Step 1: in image processing software, the main document of need printing is carried out split tunnel, C, M, Y, K passage form independently the graphic file correspondence and count C version, M version, Y version, K version;

Step 2. transfer isolated C version, M version, Y version, K version the netting twine of 150～200 straight line/inches to respectively, the cable angle that need insert the version of treating hidden file is 45 degree; And transfer grayscale mode to, then corresponding version is gone in the hidden file distortion displacement of treating of correspondence;

Step 3. each domain of treating hidden file be will insert again and pattern bitmap, storage file looked like to transfer to;

Step 4. newly-built plate-making file in software for composing, insert each edition file that step 3 obtains, and repeatedly seal is set, storage file, i.e. plate-making is accomplished, and has obtained inserting the graphic file to be printed of implicit pattern.

Before said step 1, also in turn include the following steps:

(1) elder generation opens the master file that needs printing and need be hidden at least one hidden file in the said master file in image processing software; Newly-built passage under master file again; Count covert channel; The number of said covert channel is identical with the number of treating hidden file, then hidden file is copied into newly-built passage correspondingly, and moves to predetermined separately stowed position respectively;

(2) the fuzzy one by one or virtualization with each covert channel, and the image of each hidden file is rotated corresponding angle according to the angle of need implicit pattern; Be stored as the unique file measure-alike with master file---treat hidden file;

(3) with each said covert channel deletion;

Then master file is become pixel more than the 800dpi under the constant prerequisite of size; Around the master file image, keep to the side to add an auxiliary wire frame most, the color of said auxiliary wire frame is CMYK 50%～100%.

Said hidden file is 3, and first hidden file is predetermined hidden file of inserting the C version in step (2), and the angle of its rotation is+30 degree; Second hidden file is predetermined hidden file of inserting the K version in step (2), and the angle of its rotation is-30 degree; When transferring isolated each edition to netting twine respectively in the said step 2, the angle that C version, M version, three mass-tones of K version transfer netting twine to is 45 degree, and the angle that the Y version transfers netting twine to is 90 °.

Adopt Photoshop 7.0 or above software, in said step 2, isolated C version, M version, Y version, K version transferred to respectively after the netting twine, operate in C version, M version, Y version, K version respectively:

Carry out following concrete operations on the said M version successively:

" image " on click tools hurdle → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " screen density ": 175 straight line/inches, " angle ": 45 degree, " shape ": straight line → " confirming ".Being pattern bitmap now, is to encrypt, and must change GTG, and concrete operations are to click " image " → " pattern " → " gray scale " → " size ": 1 → " confirming ";

Concealed encrypted: " filter " → " distortion " → " displacement " on a. click tools hurdle; Horizontal proportion (1) %, vertical scale (1) %; → " confirming " → choosing the file of formerly preserving conceals M.psd → " opening "; The M version be shown as just hide partly to the right, move down between netting twine and netting twine, accomplish the pattern of C version to hide; Pattern transfers bitmap to: click " image " → " pattern " → " bitmap " → " output ": 1200 pixel/inch, " use ": diffusion colour combination → " confirming ", save as the .GIF formatted file then, and count " main M.GIF " file for standby;

Carry out following concrete operations on the said K version successively:

" image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " counterclockwise " → " confirming ";

Click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " screen density ": 175 straight line/inches, " angle ": 45 degree, " shape ": straight line → " confirming "; Transfer grayscale mode then to, size is 1;

Concealed encrypted: click tools hurdle " filter " → " distortion " → " displacement "; Horizontal proportion 1%, vertical scale-1%; → " confirming " → choosing the file of formerly preserving conceals K.psd → " opening "; The K version shows to institute just to be hidden partly to the right, moves down between netting twine and netting twine, second pattern of completion hiding.

" image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " clockwise " → " confirming "; Unnecessary space occurs now, utilize crop tool, cut out the redundance beyond the said auxiliary wire frame and go; Transfer the K version to pattern bitmap again: click tools hurdle " image " → " pattern " → " bitmap "; → " output ": 1200 (pixel/inch); " use ": diffusion colour combination → " confirming ", save as the .GIF formatted file, count " main K.GIF " file for standby;

Carry out following concrete operations on the said C version successively:

" image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " clockwise " → " confirming ";

Click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → frequency 175, straight line/inch, " angle ": 45, " shape ": straight line → " confirming "; Transfer grayscale mode then to, size: 1;

Concealed encrypted: click tools hurdle " filter " → " distortion " → " displacement "; Horizontal proportion (1) %, vertical scale (1) %; → " confirming " → choosing the file of formerly preserving conceals C.psd → " opening "; The C version show to institute hide partly to the right, mobile just between netting twine and netting twine down, accomplish the hiding of the 3rd pattern;

To file be gone back to level: " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " counterclockwise " → " confirming "; Unnecessary space occurs now, utilize crop tool, cut out the redundance beyond the said auxiliary wire frame and go; Transfer the C version to pattern bitmap again: click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch); " use ": diffusion colour combination → " confirming "; Save as the .GIF formatted file, count " main C.GIF " file for standby;

Carry out following concrete operations on the Y version successively:

Click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " frequency ": 175 line/inches, " angle ": 90, " shape ": straight line → " confirming "; Be bitmap now, save as the .GIF formatted file, count " main Y.GIF " file for standby.

This method also comprises makes supporting verification tool: new files in image processing software; Gray scale; Background color 50% look is designated as the detection file, and the size that detects file is identical with said main document with pixel size; And the image that will detect file is converted into and is used for the 45 degree netting twines that the corresponding version frequency of implicit pattern matches, and preserves checking file.

Simultaneously, the method that the present invention makes implicit pattern when also providing another kind of printed matter to make a plate comprises the steps:

Step 1. in image processing software, the image of main document to be printed is carried out the identical pre-determined number and the torsional deformation of predetermined angular with the image of treating hidden file in identical select location and scope correspondence;

Step 2. with the main document split tunnel, the independent drawing file correspondence that C, M, Y, K passage form is counted C version, M version, Y version, K version;

Step 3. transfer isolated C version, M version, Y version, K domain picture the netting twine of 150～200 straight line/inches to respectively, the cable angle that need insert the version of treating hidden file is 45 degree; And transfer grayscale mode to, then corresponding version, storage file are respectively gone in the corresponding one by one distortion displacement of hidden file of treating that correspondence was twisted;

Step 4. make the instruments of inspection: new files in image processing software; Gray scale, background color 50% look is designated as the detection file; The number that detects file is identical with the number of treating hidden file; Size is identical with main document with pixel size, and with each detect document image be converted into be used for the corresponding version frequency of implicit pattern identical 45 spend netting twines, preserve each checking file;

Step 5. it is a CMYK four look files that the C version that (1) obtains step 3, M version, Y version, K version unique file reconfigure;

(2) newly-built check passage and under the document, the number of check passage is identical with said checking file number, and corresponding one by one copy of each checking file image pasted on the said check passage;

(3) reduce distortion then; Promptly; The image of the image of C version, M version, Y version, K version and each sense channel is carried out the torsional deformation of select location identical with step 1 and scope, the number of times identical with step 1, the predetermined angular opposite with step 1 respectively, thereby the image and the hidden image of main document is reduced to image to be printed;

Step 6. the main document that step 5 reduction is obtained carries out split tunnel, obtains independently checking file of C version, M version, Y version, K version unique file and each;

Step 7. the image of each unique file that step 6 is obtained transfers pattern bitmap, storage file respectively to;

Step 8. newly-built plate-making file in software for composing, insert C version, M version, Y version, K version unique file that step 7 obtains, and repeatedly seal is set, storage file, i.e. plate-making is accomplished, and has obtained inserting the graphic file to be printed of implicit pattern and distortion netting twine.

After said step 7, carry out step 9: a newly-built plate-making file in software for composing, insert each checking file that step 7 obtains, in-line sequences, and color settings is gone into K100%, promptly obtains treating out the testing tool graphic file of the film.

The method of said step 1 is:

(1) elder generation opens the main document that needs printing and need be hidden in the hidden file in the said main document in image processing software; Newly-built passage under main document again; Be designated as covert channel; The number of said covert channel is identical with the number of treating hidden file, then hidden file is copied into newly-built passage correspondingly, and moves to predetermined separately stowed position respectively;

(2) again at the newly-built passage of main document; Be designated as the distortion passage, select frame to choose different positions and scope with square at each distortion passage, and fixing constituency; Be used for limiting the position and the scope of distortion netting twine, the number of said distortion passage is identical with the number of pending distortion;

(3) under the prerequisite that keeps size constancy, the main document pixel size is changed greater than 800dpi into storage file;

(4) under the described position and scope of respectively twisting passage and being limited of step (2), the main document image that step (3) is obtained carries out the distortion of each different angles;

In said step 1 (4) afterwards, before the said step 2 split tunnel, around main document, keep to the side to add an auxiliary wire frame most earlier, the color of said auxiliary wire frame is CMYK 50%～100%; After said step 2, the pixel size of the unique file that each covert channel is formed changes 100-300dpi into, fuzzy one by one or virtualization, and the image canvas of each hidden file is done corresponding rotation according to the angle of need implicit pattern; Be stored as the unique file measure-alike with master file---treat hidden file.

The implementation method of said step 5 (1) is: the main document that opening steps one (3) storage obtains, keep C, M, Y, K and each distortion passage, and delete each covert channel; The corresponding one by one copy of the netting twine formula image of the C that then step 3 is obtained, M, Y, each edition of K file pastes on the C, M, Y, K passage of the main document that step 1 (3) obtains, replaces original CMYK image, has realized that promptly it is a CMYK four look files that C version, M version, Y version, K version after distortion and the netting twineization reconfigures;

Said step 5 (2) afterwards, step 5 (3) before, the position beyond the main document painting canvas epigraph draws telltale mark, makes under this main document all corresponding telltale mark that forms in all passages.

The method for making of netting twine multi-angle implicit pattern of the present invention; By image processing software Photoshop, it is hiding to utilize the netting twine dislocation to make, the density of netting twine and cable angle in the first still image; Use the dislocation instrument again, with carrying out the dislocation of hiding picture or literal.Set type with Illustrator of software for composing or CorelDraw after accomplishing, export the film (comprising testing tool) then, print or work out a draft (can not use printings such as number or ink-jet).With the naked eye can't see the pattern of being hidden on the printed matter, also have no vestige, just can know and see the image of being hidden significantly and on printed matter, add a film (testing tool).Shown in Fig. 4 A; Be that the netting twine that utilizes of the present invention is made the printed matter that implicit pattern is arranged that the multi-angle implicit pattern obtains; The enlarged image of when not adding testing tool, seeing; Be the enlarged image of seeing when on Fig. 4 A, having added the relevant detection instrument shown in Fig. 4 B, " just " word among the figure is false proof hiding pattern.

Because of colored printing is made up of C, M, Y, K four looks (4C); And four looks respectively have the angle of every look; Image and depth level are made up of the size of site or netting twine, but the netting twine of each angle of this concealing technology (1C) do one and hide, hide so can do three at same position; As add three special looks that netting twine is arranged, hide just can do six at same position.The pattern of hiding is through the processing of blur tool, and there is transition at the edge of institute's hidden image, the submissive nature that becomes, and it is stiff can not make.And the edge of hidden image is shifted suddenly in the prior art, and is very stiff, can see the vestige at hidden image edge.The present invention also is difficult for cracking than the method for anti-counterfeit of background technology more.Printing and encryption and false proof usefulness as implicit pattern can not increase printing cost, detect very easily yet, do not influence design colours.Yet the anti-fake product that this method is processed also has the chance that is cracked.

Simultaneously, the present invention also provides and has utilized the distortion netting twine to make implicit pattern, optionally chooses one or more square constituencies (size is regardless of) in the place that hiding scope is arranged; Utilize instruments such as distortion, rotation, make the netting twine torsional deformation (testing tool synchronous processing) in the constituency again, the rule of netting twine promptly changes to some extent; Can repeat to do repeatedly, each constituency is different, and available similar and different instrument carries out; The constituency number of times the more, the chance that can crack is fewer.This implicit pattern can not be seen hidden image clearly with general netting twine testing tool, even can't see.Because as to see hidden image, the netting twine of testing tool will twist synchronously.As will crack, to accurately find the constituency scope earlier, also will accurately know the strong and weak number of degrees of distortion and know is to adopt which distortion instrument; This is unusual difficulty, have only very small probability can miss by chance in target, just be that the wright repeats to do repeatedly even tens of inferior; And the constituency is not of uniform size, utilizes each distortion instrument and different strong and weak numerical value again respectively, even the file that I make; If file is lost, I also am difficult to make again.We can say that the hidden file made from the distortion netting twine is unique, finger mould and DNA like the people make the cracker that There is no way to begin, and this has just further remedied the deficiency that still might be cracked in the making of netting twine multi-angle implicit pattern.Shown in Fig. 5 A, be that the present invention utilizes the distortion netting twine to make the printed matter that implicit pattern is arranged that the multi-angle implicit pattern obtains, the enlarged image of when not adding testing tool, seeing; Be the enlarged image of seeing when on Fig. 5 A, having added existing common testing tool shown in Fig. 5 B, visiblely can't discern implicit pattern; Be the enlarged image of seeing when on Fig. 5 A, having added the testing tool of the supporting synchronous distortion of the present invention shown in Fig. 5 C, " just " word among the figure is false proof hiding pattern.

The present invention makes implicit pattern through the plate-making before printing, and the file that it is good that the technician will make a plate is issued printery before printing just passable, and printery need not to know whether implicit pattern is arranged, and can not increase printing cost.

The printed matter that the inventive method Plate making printing obtains; Do not add testing tool and can't see hidden image; So need the suitable testing tool of plate-making, the film of plate-making output can be used as basic detection method, hides the implicit pattern that makes for multi-angle; Several kinds of available detection methods below also having, precision sweep appearance scanning capable of using have added hiding printed matter and have done following the detection:

1. do an emulation testing tool on computers earlier and amplify on the apparent apparent screen of several times, overlap the image synchronization amplification that has scanned on the emulation testing tool, also can see hidden image;

2. on the projection plate, stamp the testing tool that amplifies several times earlier, the image synchronization that will scan again amplification is incident upon on the projection plate, also can see hidden image;

3. utilize printer, on printer paper, be printed on the testing tool that amplifies several times in advance, the image synchronization that will scan again amplification is printed on the printer paper, also can see hidden image.

Adopt the file that obtains after the implicit pattern method plate-making of the present invention; Can be used in aspects such as paper printing, silk-screen, moth quarter (for example plastics, metal etc.), computer sculpture, laser engraving, embossing; Applicable to various product; For example cigarette case, wine box, medicine box, electronic product box, minaudiere, DVD box/VCD box, regular software box, Games Software box, or the like; It is false proof to be used for member card, cash certificate, admission ticket, ticket, lottery ticket etc., also can be used to play, hiding answer of reference book and detective story, campaign etc.Also can be used as logistics management, the word of for example hiding can be Beijing (representative is sold in Beijing), Heilungkiang (representative is sold in Heilungkiang) or the like.The word of hiding can be Beijing 111224 (representative is release sale on Dec 24th, 2011 in Beijing).Top management can be removed to offer an explanation product through eyeglass and is distributed in each town, each city, each province.

Embodiment

Embodiment 1

A. make the multi-angle implicit pattern in the graphic file to be printed

Choose PaintShop do not have mandatory, can reach requirement just can, for example the Illustrator that uses always of those skilled in the art and Photoshop7.0 or more than.File before the printing is forms such as .ai .cdr .GIF .jpg .psd.Make the basic demand of file process: before main document to be printed transfers netting twine to; Must be under the prerequisite of size constancy change original resolution into 1200dpi (resolving range more than 800dpi all can), pattern file resolution to be hidden is adjusted into 300dpi (resolving range more than 100dpi all can), has only dark or the most shallow look (for example literal class) like pattern; Must blur (Gaussian Blur; Numerical value intensity 1 pixel or more than), if the image of portrait or photograph and so on does not have only uneven color; Look between excessively extremely shallow deeply in addition, the periphery must virtualization.Stowed position need meet certain condition, under 10%-90% netting twine basis, produces effect, and wherein the effect with the 40%-60% netting twine is the most obvious.Netting twine must be miter angle or-miter angle.The position color of being hidden can not be too dark, and near-black for example also can not be too colored, otherwise promptly enable to manifest hiding thing but can not see clearly.

Below be the concrete making step of three implicit patterns of colored printing CMYK plate-making:

In the present embodiment, main image file to be printed is that Illustrator software is set type, called after " ABC.ai ", and accomplishing size is that 121mm height * 126mm is wide, and pixel is 300dpi, and pattern CMYK is this document unloading main document .GIF; The pattern of hiding three palpuses with Illustrator software again (literal or image) is ready to, and pixel is 300dpi, and unloading is the .GIF form, the called after first hidden file .GIF, the second hidden file .GIF, the 3rd hidden file .GIF.Open Photoshop 7.0 softwares then, begin to make:

1. open the main document .GIF and the first hidden file .GIF, the second hidden file .GIF, the 3rd hidden file .GIF; At newly-built three passages of main document; For ease of address; Count covert channel; On second covert channel that first hidden file .GIF copy is pasted on first covert channel of main document, second hidden file .GIF copy pastes main document, the 3rd hidden file .GIF copy pastes on the 3rd covert channel of main document, and move to respectively on the position that the image of main document is fit to hide.

2. adopt Gaussian Blur (intensity: 1.0) to three covert channels respectively; Save as 3 independently .psd formatted files then respectively; The latent C.psd of called after, latent M.psd, latent K.psd notice that the picture size of these three files must conform to main document picture size respectively.Subsequent use+30 ° of preservations of the image canvas of latent C.psd file rotation again, subsequent use-30 ° of preservations of the image canvas of latent K.psd file rotation.

3. with three of main document newly-built covert channel deletions; And the image of the former 300dpi of being become pixel 1200dpi (more than the 800dpi all can) under the constant prerequisite of size; And keep to the side to add an auxiliary wire frame (as gyration cut out usefulness at last) around the image most; The color of auxiliary wire frame be CMYK 100% (auxiliary wire frame color be 50%～100% all can, numerical value is high more clear more).

4. with the main document split tunnel, obtain C version, M version, Y version, K version.

Following steps 5-7 transfers C, M, K version to angle identical netting twine respectively, is preferably with 45 ° to be as the criterion, and the Y version can directly be changeed 90 ° of netting twines.And twist displacement in C, M, K version and go into the pattern that corresponding need are hidden.

5. begin to make the M version now, on the M version of separating, operate:

(1) clicks " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " screen density ": 175 straight line/inches, " angle ": 45 degree, " shape ": straight line → " confirming ".Being pattern bitmap now, is to encrypt, and must change gray scale, and concrete operations are to click " image " → " pattern " → " gray scale " → " size ": 1 → " confirming ".Wherein, no matter be that C version, M version, Y version are identical with K version netting twine " frequency ", " frequency " scope can be 150-200 straight line/inch.

(2) beginning is concealed encrypted, also is topmost step:

A. " filter " → " distortion " → " displacement " on the click tools hurdle; Horizontal proportion (1) %, vertical scale (1) %; → " confirming " → choosing the file of formerly preserving conceals M.psd → " opening "; The M version be shown as just hide partly to the right, move down between netting twine and netting twine, as shown in Figure 1.Accomplishing first hides.

B. pattern transfers bitmap to, clicks " image " → " pattern " → " bitmap " → " output ": 1200 pixel/inch, " use ": diffusion colour combination → " confirming " saves as " main M.GIF " file for standby then.

6. begin to make the K version now, on the K version of separating, operate:

(1) the K version is 75 degree; And latent K file has rotated-30 ° in step 2; Because carry out concealed encrypted angle must be 45 °; So need be with-30 ° (45 °-75 °=-30 °) of K version rotation, " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, counterclockwise → " confirming ".

(2) refer again to the step making K version that step 5 is made the M version." image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " screen density ": 175 straight line/inches, " angle ": 45 degree, " shape ": straight line → " confirming ".Transfer bitmap to grayscale mode (size: 1) then.The netting twine that concealed encrypted image needs is 45 ° or-45 °, just is 45 degree now.

(3) beginning is concealed encrypted, also is topmost step.

Click " filter " → " distortion " → " displacement "; Horizontal proportion (1) %, vertical scale (1) %; The latent K.psd of the file that → " confirming " → choose formerly preserved → open, the K version show to institute hide partly to the right, following mobile just between netting twine and netting twine, as shown in Figure 2.Accomplishing second hides.

(4) rotate-30 ° because of the K version, must K version file have been gone back to level now: " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, clockwise → " confirming ".Unnecessary space occurs now, utilize crop tool, cut out the redundance beyond the added auxiliary wire frame of step 3 and go.Transfer the K version to pattern bitmap again: click tools hurdle " image " → " pattern " → " bitmap ", → " output ": 1200 (pixel/inch), " use ": diffusion colour combination → " confirming " stores and called after " main K.GIF " file for standby.

7. begin to make the C version now, on the C version of separating, operate.

(1) C version angle is 15 °; And latent C file has rotated in step 2+30 °; Because carry out concealed encrypted angle must be 45 °; So need be with 30 ° (45 °-15 °=30 °) of C version rotation, " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " clockwise " → " confirming ".

(2) refer again to the program making C version that step 5 is made the M version.Click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → frequency 175, straight line/inch, " angle ": 45, " shape ": straight line → " confirming ".Transfer bitmap to grayscale mode (size: 1) then.The netting twine that concealed encrypted image needs is 45 ° or-45 °, just is 45 ° now.

(3) beginning is concealed encrypted, also is topmost step:

Click tools hurdle " filter " → " distortion " → " displacement "; Horizontal proportion (1) %, vertical scale (1) %; → " confirming " → choosing the file of formerly preserving conceals C.psd → " opening "; The C version show to institute hide partly to the right, mobile just between netting twine and netting twine down, accomplish the 3rd hiding.

(4) because of the C version rotated+30 °, must file be gone back to level now." image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, counterclockwise → " confirming ".Now, unnecessary space occurred around the image, utilized crop tool, cut out the redundance beyond the added auxiliary wire frame of step 3 and go.Transfer the C version to pattern bitmap again: click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": diffusion colour combination → " confirming " stores and called after " main C.GIF " file for standby.

8. begin to make the Y version now

Click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " frequency ": 175 line/inches, " angle ": 90, " shape ": straight line → " confirming ".Be bitmap now.The file for standby of storage and called after " main Y.GIF " form.

9. set type:

Utilize Illustrator software to set type: a newly-built file, insert above-mentioned " the main C.tvif " that completes, " main M.GIF ", " main Y.GIF ", " main K.GIF " file, main Y.GIF file color settings is Y100%; Set repeatedly seal again, main C.GIF file color settings is C100%, sets repeatedly seal again; Main M.GIF file color settings is M100%, sets repeatedly seal again, and main K.GIF file color settings is K100%; Set repeatedly seal again, choose C again, M; Y, about four shelves of K are set, about placed in the middle.Storage and called after " multi-angle is hidden o k.ai ", the graphic file to be printed that promptly obtains making a plate and accomplish has wherein been hidden three patterns at 45 degree, 15 degree and 75 degree, can be the printed matter encryption that prints and false proof.

B. make supporting verification tool:

The printed matter that the inventive method Plate making printing obtains; Do not add testing tool and can't see hidden image; Add suitable testing tool and just can be clear that the image of being hidden; The color of testing tool generally can be selected black, because manifest the most clearly, and also available C look, M look or other darker special look.

In order to verify the implicit pattern in the printed matter, need to make supporting verification tool, step is following:

(1) open Photoshop software, newly-built one new file 90 * 50mm, gray scale, 1200dpi, background color are 50%.The size of verification tool is not limit, and is advisable to carry easily, can be the same with printing figure big according to conveniently processing of use yet.

(2) click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " frequency " 175 straight line/inches, " angle ": 45, " shape ": straight line → " confirming ".Preserve file, called after " 157 detect ", form is .GIF, accomplishes.

" frequency " scope can be 175-200 straight line/inch, must be identical with the frequency of each edition file.

The exportable film of this document makes to detect usefulness, notes can not dwindling or amplify with 100% output.

After printed matter and testing tool (film) print off; The method of inspection is: because the testing tool netting twine is 45 degree; Directly be placed on and made the implicit pattern that just can see the M version on the hiding printed matter; Change the implicit pattern that 30 degree can be seen the K version to testing tool clockwise again, change the implicit pattern that 60 degree can be seen the C version to testing tool counterclockwise again.

Embodiment 2

Make implicit pattern with the distortion netting twine in the graphic file to be printed

The basic demand of the preparation of main document and hidden file and making file process is similar with embodiment 1, repeats no more.Be ready to main document .GIF and three hidden file first hidden file .GIF, the second hidden file .GIF, the 3rd hidden file .GIF.Open Photoshop 7.0 softwares then, begin to make:

1. open the main document .GIF and the first hidden file .GIF, the second hidden file .GIF, the 3rd hidden file .GIF; Passage at newly-built 3 the copy implicit patterns of main document .GIF; Be convenient address; Can be described as covert channel; First hidden file .GIF copy is pasted on first covert channel of main document, second hidden file .GIF copy pastes on second covert channel, the 3rd hidden file .GIF copy pastes on the 3rd covert channel, and move to respectively on the position that the image of main document is fit to hide.

2. at newly-built again 4 passages of main document .GIF; For convenient address, can be described as the distortion passage, count distortion passage 1, distortion passage 2, distortion passage 3, distortion passage 4, each distortion passage and select frame to choose different positions and scope with square; And fixing constituency; Fixedly the concrete operations in constituency can be to click " selection " → " storage constituency " → name at toolbar, and " confirming " just increased a passage, is used for limiting the position and the scope of distortion netting twine.(to do distortion several times, then will be at the distortion passage of newly-built corresponding several definite distortion positions of main document and scope.)

3. under the situation that keeps size constancy, change the main document pixel size into 1200dpi, the called after master twists .GIF, and is subsequent use.

4. distortion:

" main distortion .GIF " under the file, choose distortion passage 1, the C M Y K look of click-through window, click tools hurdle " filter " → " distortion " → " rotation distortion " → " angle " :+8 → definite.Click 3 covert channels then, repeat same step, windup-degree is 8 degree.

Choose distortion passage 2 then, the C M Y K look of click-through window repeats same step, and windup-degree is+15, clicks 3 covert channels then, repeats same step, and windup-degree is+15 degree.

Choose distortion passage 3 then, the C M Y K look of click-through window repeats same step, and windup-degree is+10, clicks 3 covert channels then, repeats same step, and windup-degree is+10 degree.

Choose distortion passage 4 then, the C M Y K look of click-through window repeats same step, and windup-degree is+20, clicks 3 covert channels then, repeats same step, and windup-degree is+20 degree.

This has just accomplished the distortion step.

5. with the deletion of four distortion passages; Around main document, keep to the side to add an auxiliary wire frame most.To the main document split tunnel, seven unique files occur then, wherein 4 is C version, M version, Y version, K version, and other 3 is that covert channel forms.

Elder generation changes the pixel size of the unique file that three covert channels form into 300dpi by 1200dpi; And fuzzy respectively---Gaussian Blur (intensity: 1.0); Store respectively and called after: turn round latent C.psd, turn round latent M.psd, turn round latent K.psd; Form is .psd, turns round latent C.psd file rotation and stores for+30 ° again.Turning round latent K file rotation stores for-30 ° again.

6. begin to make the M version now, on the M version of separating, operate:

(1) click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch); " use ": halftone screen → " confirming " → " frequency ": 175 line/inches; " angle ": 45, " shape ": straight line → " confirming ".This just is converted into the M version netting twine pattern of 45 ° of angles.Be pattern bitmap now, can not carry out concealed encryptedly, must will change gray scale earlier: click tools hurdle " image " → " pattern " → " gray scale " → " size ": 1 → " confirming ".

(2) beginning hidden image also is topmost step:

" filter " → " distortion " → " displacement " on the click tools hurdle; Horizontal proportion (1) %, vertical scale (1) %; → " confirming " → choose the file of formerly preserving to turn round latent M.psd → " opening "; The M version be shown as just hide partly to the right, move down between netting twine and netting twine, accomplish first to hide, store and called after " the main C.GIF that turns round ".

7. begin to make the K version now, on the K version of separating, operate:

(1) K version angle should be 75 °; Because carry out concealed encrypted angle, it must be 45 °, so transfer-30 ° (45 °-75 °=-30 °) to; " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " counterclockwise " → " confirming ".

(2) refer again to the step making K version that step 6 is made the M version: " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → " screen density ": 175 straight line/inches, " angle ": 45 degree, " shape ": straight line → " confirming ".Be bitmap now, transfer grayscale mode (size: 1) earlier to.The netting twine that concealed encrypted image needs is 45 ° or-45 °, just is 45 ° now.

(3) beginning is concealed encrypted, also is topmost step:

Click " filter " → " distortion " → " displacement "; Horizontal proportion (1) %, vertical scale (1) %; The file that → " confirming " → choose formerly preserved is turned round latent K.psd → open, the K version show to institute hide partly to the right, mobile just between netting twine and netting twine down, accomplish second hiding.

(4) rotate-30 ° because of the K version, must K version file have been gone back to level now: " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " clockwise " → " confirming ".Unnecessary space occurs now, utilize crop tool, cut out the redundance beyond the added wire frame of step 5 and go.Store and called after " the main K.GIF that turns round ".

8. begin to make the C version now, on the C version of separating, operate:

(1) C version angle should be 15 °; Because carry out concealed encrypted angle must be 45 °; So transfer 30 ° (45 °-15 °=30 °) to, " image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " clockwise " → " confirming ".

(2) with reference to the procedure operation of M version in the step 6: click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch), " use ": halftone screen → " confirming " → frequency 175, straight line/inch, " angle ": 45, " shape ": straight line → " confirming ".Be bitmap now, transfer grayscale mode (size: 1) earlier to.The netting twine that concealed encrypted image needs is 45 ° or-45 °, just is 45 ° now.

(3) beginning is concealed encrypted, also is topmost step:

Click " filter " → " distortion " → " displacement "; Horizontal proportion (1) %, vertical scale (1) %; → " confirming " → choose the file of formerly preserving to turn round latent C.psd → " opening "; The C version show to institute hide partly to the right, mobile just between netting twine and netting twine down, accomplish the 3rd hiding.

(4) because of the C version rotated+30 °, must file be gone back to level now." image " on click tools hurdle → " Rotate Canvas " → " arbitrarily angled " → " angle ": 30, " counterclockwise " → " confirming ".Unnecessary space occurs now, utilize crop tool, cut out the redundance beyond the added wire frame of step 5 and go, file stores and called after " the main C.GIF that turns round ".

9. begin to make the Y version now, on the Y version of separating, operate:

Click tools hurdle " image " → " pattern " → " bitmap " → " output ": 1200 (pixel/inch); " use ": halftone screen → " confirming " → " frequency ": 175 line/inches; " angle ": 90; " shape ": straight line → " confirming ", file stores and called after " the main Y.GIF that turns round ".

10. when making a plate, makes by printed matter according to claim 9 the method for implicit pattern; It is characterized in that; The implementation method of said step 5 (1) is: the main document that opening steps one (3) storage obtains, keep C, M, Y, K and each distortion passage, and delete each covert channel; The corresponding one by one copy of the netting twine formula image of the C that then step 3 is obtained, M, Y, each edition of K file pastes on the C, M, Y, K passage of the main document that step 1 (3) obtains, replaces original CMYK image, has realized that promptly it is a CMYK four look files that C version, M version, Y version, K version after distortion and the netting twineization reconfigures;

Said step 5 (2) afterwards, step 5 (3) before, the position beyond the main document painting canvas epigraph draws telltale mark, makes under this main document all corresponding telltale mark that forms in all passages.
