Abstract

Leakage of information from a high-quality copy created by reading out data from a storage device is inhibited. A printing apparatus ( 110 ) and a multi-function peripheral ( 120 ) which is connected to a network ( 130 ) store images each corresponding to an identification information. These apparatuses extract an identification information from a document for which a unique identification information is formed, and search a storage device for an image containing an identification information which coincides with the unique identification information. The apparatuses acquire the found image, form copy-forgery-inhibited-pattern image information on the image, and print.

Description

Image processing apparatus and control method thereof

Technical field

The present invention relates to have from storage device and read the image corresponding and the image processing apparatus and the control method thereof of the function of printing with reading original copy.

Background technology

In the past, utilized that photocopier etc. is optically read to be printed on printed matter on the paper by copy function with image, generated view data.Different therewith, exist in to utilize in printed matter that printer makes and the view data and embed identical identification id, the view data that has embedded this identification id is stored in temporarily in the storage device of the equipment that connects by network, then, duplicate when utilizing the printed matter that printer makes in indication, retrieve view data of being stored and the technology of printing (for example opening flat 10-308868 communique) with reference to the spy according to the identification id of printed matter.Like this, even if utilize the image quality of the printed matter that printer makes to worsen, when this printed matter is duplicated in indication, the printed matter of exportable high image quality still.

In addition, in recent years, along with the raising of awareness of safety, the management method of printing export also receives publicity.As the technology that is directed to this, (shading printing) technology that the known reproduction that has utilization to duplicate (scanning) limits.This technology is to synthesize and be formed on output with the technology on the paper having embedded the shading image of character strings such as " COPY " and content images.In addition, when duplicating this export, character strings such as " COPY " of embedding can be appeared in one's mind on duplicate and (for example holds the 2001-324898 communique with reference to the spy).

This printed matter exported after shading image and the content images of having synthesized is carried out the people who duplicates and obtain duplicate and seen that this character string just can take into account information and outflowed, perhaps recognize important information and can not be carried to outside the company.Therefore, shading is a kind ofly to consider human psychology and anti-information outflows in the technology of possible trouble, also is the technology that has guaranteed certain fail safe.

Below, describe shading image in detail.In shading image, embedded the character strings such as " COPY " that the people looks and can not find out.On the other hand, by duplicating on the duplicate that this shading image obtains, the character string of this embedding is appeared in one's mind out.Therefore, synthesized and be formed on output behind such shading image and the original image and can easily distinguish mutually with its duplicate with the file on the paper (below be called original).In addition, because character strings such as " COPY " reveals to come in the duplicate come-up, duplicating person is hesitated in the use of duplicate.

This shading image is made of two zones.Zone is the zone of " residual " on the duplicate when being replicated, and another zone is " disappearance " (or " comparing thin out with above-mentioned residual region ") zone.In addition, the reflection density in these two zones is basic identical on original.Therefore, for human eye, can not differentiate character strings such as having embedded " C ".Here so-called " residual " mean that the image on the original correctly is rendered on the duplicate, and so-called " disappearance " means that the image on the original is not rendered on the duplicate.In addition, reflection density is measured by reflection of the concentration.

Below the zone of " residual " on the duplicate is called " sub-image portion ", (or " comparing thin out with above-mentioned the residual region ") zone of " disappearance " on the duplicate is called " background portion ".

Figure 21 is the figure of the lattice point state of expression shading image.Among the figure, lattice point is a sub-image portion by the zone of centralized configuration, and lattice point is a background portion by the zone of decentralized configuration.Lattice point in these two zones handles by different sites respectively or different dithering process generates.For example, the lattice point of sub-image portion is handled by the site of low line number and is generated, and the lattice point of background portion is handled by the site of high line number and is generated.Perhaps, the lattice point of sub-image portion uses lattice point concentrated dither matrix to be generated, and the lattice point of background portion uses lattice point decentralized dither matrix to be generated.

But,, thereby have capacity limit because the reproduction of photocopier depends on input resolution and the output resolution ratio that photocopier has.Therefore, lattice point in the sub-image portion of shading image is formed greater than the reproducible lattice point of photocopier, and the lattice point of background portion is formed under the situation less than reproducible lattice point, generally is difficult to reproduce the lattice point of the background portion of the image that has reproduced sub-image portion lattice point on duplicate.The result compares with background portion on duplicate, and sub-image portion is reproduced denselyer.After, will appear out the video pictureization that is called in sight in one's mind by make sub-image portion on duplicate, reproduce character string of making embedding etc. denselyer than background portion.

Among Figure 21 2101 and 2102 is figure of this video pictureization of expression.This figure is conceptive to be shown concentrated lattice point (big lattice point) and is rendered on the duplicate and disperses lattice point (little lattice point) correctly not to be rendered to situation on the duplicate.

In addition, shading image is not limited to said structure, also can constitute to manifest (video pictureization) human discernible character strings such as " COPY ", mark or pattern etc. on duplicate.In addition, even if on duplicate, represent character strings such as " COPY ", think that also this shading image can achieve the goal with hollow state.At this moment, certain zone with " COPY " is called background portion.More than the explanation of shading image is finished.

But, as mentioned above, duplicate additionally when the printed matter of identifying information is arranged in indication, can read the image corresponding from storage device, the duplicate of output high image quality with it.But, in distribution during this duplicate, have that the duplicate of holding this distribution goes out to duplicate and the problem that makes the secure context of information outflow.

Summary of the invention

The present invention considers that these situations make, and according to the present invention, purpose provides a kind of image processing apparatus and control method thereof that suppresses information from the behavior of reading the high image quality duplicate outflow of making from storage device.

For addressing the above problem, image processing apparatus of the present invention has following structure:

In step S403, printing control unit 211 is carried out the selection on storage purpose ground, and the selection on this storage purpose ground is meant the storage device of the original image of selecting the storing image data form.Fig. 5 is the flow chart that the details of processing is selected on the storage purpose ground among the description of step S403.Describe this processing below in detail.

In step S501, in printing control unit 211 decision makers self in the printing equipment 110 whether storage (ROM, HDD etc.) is arranged.In the result of determination of step S501 is to have in the device self under the situation of storage (being), enters step S502.On the other hand, in device self, do not have to enter step S504 under the situation of storage (denying).

In step S502, printing control unit 211 is calculated the size of data of the view data that the original image data according to the intermediate language form generate, by the vacant capacity of this size of data and storage area relatively, judgement could be stored in the original image data in the storage in the device self with image data format.In addition, the size of data of the view data that generates according to intermediate data 214 is decided by number, resolution, tonal gradation number.For example, resolution is that 600dpi, tonal gradation are that the size of data of the monochromatic data of 1bpp (position every pixel) is about 4MB * number of pages.In addition, also can carry out the judgement of this step to use the size of data after arbitrarily encoding method is encoded to data.

Result of determination at step S502 is under the situation about can store in device self (being), enters step S503.On the other hand, be judged to be that (denying) enters step S504 under the situation that can not carry out the storage in the device self.In step S504, retrieve the processing of the storage in this device device in addition.

Fig. 6 is the flow chart of the details handled of the memory scan that carries out of description of step S504.Describe this processing below in detail.In step S601, printing control unit 211 generates grouped data shown in Figure 9.Then, data sending part 212 not specific multiple arrangement on network 130 sends this grouped data.To send grouped data to not specific multiple arrangement below and be called broadcasting.In this grouped data, record and narrate the address that expression sends the address of destination (printing equipment 110) in 901, record and narrate the address of expression transmission source address in 902, record and narrate the order of expression " memory scan " in 903.In addition, memory scan is handled and is not limited to said method.

In step S602, whether printing control unit 211 investigation reply the broadcasting that step S601 carries out.Consequently having under the situation of replying (is) to enter step S603, (denys) to enter step S604 under the situation of not replying.The following describes 120 pairs of above-mentioned broadcastings of compounding machine the situation of replying is arranged.

In step S603, printing control unit 221 investigation are as whether storing the original image data among the HDD124 in the compounding machine 120 of the device of replying.This processing is the identical processing of determination processing of the step S502 in the flow chart with Fig. 5.When carrying out this processing, printing control unit 221 need receive the size of data of original image data or original image data through network 130 from printing equipment 110.In addition, about this determination processing, also can not in compounding machine 120, in printing equipment 110, carry out.

In step S603, the printing control unit 221 in compounding machine 120 is judged and can be installed under the stored original image data conditions (being) at this, enters step S605.In step S605, printing control unit 221 generates grouped data shown in Figure 10.Then, send grouped data through data sending part 222 and communication interface part 126 to printing equipment 110.After grouped data sends end, enter step S505.In the grouped data shown in Figure 10, record and narrate in 1001 and send destination-address (address of compounding machine 120), record and narrate transmission source address (address of printing equipment 110) in 1002, record and narrate order (order of expression search result storage) in 1003, record and narrate storage (catalogue of storage device) in 1004, record and narrate size (vacant capacity of storage device) in 1005.After above processing finishes, enter step S505.In addition, also can not in compounding machine 120, in printing equipment 110, carry out the processing of this generation grouped data.In this case, do not need to send grouped data.

On the other hand, the printing control unit 221 in step S603 is judged to be compounding machine 120 can not be installed under the stored original image data conditions (denying) at this, moves to step S602 once more.

In step S604, the printing control unit 211 in the printing equipment 110 judge in memory scan processing etc., whether take place overtime.(be) to be judged to be to store consequently, finish memory scan and handle, enter step S505 having taken place under the overtime situation.On the other hand, (deny) to enter step S602 not taking place under the overtime situation.

In step S505, can the result that the printing control unit 211 in the printing equipment 110 is handled according to above-mentioned memory scan judges with the original image storage in certain memory.And then (be) to enter step S503 under situation about can store, (deny) to enter step S506 under situation about can not store.

Printing control unit 211 among the step S503 in the printing equipment 110 generates stored information according to the result of step S502 and step S505.In this is handled, generate grouped data shown in Figure 10.In this grouped data shown in Figure 10, record and narrate to send destination-address (as the address of the compounding machine 120 of the device that can store the original image data) in 1001, record and narrate transmission source address (as the address of the printing equipment 110 that carries out the device that PDL handles) in 1002.1003,1004,1005 as mentioned above, omits its explanation.In addition, having generated as shown in figure 10 under the situation of grouped data, do not need to generate once more.Above processing enters step S404 after finishing.

In step S404, renderer 215 is carried out to draw and is handled.Draw to handle and be meant that the original image data of intermediate language form are carried out bitmap to be launched, and generates the processing of the original image data of image data format.

In step S405, printing control unit 211 is judged the storage of whether carrying out the view data that generated.This judgement is based on the storage selection result of step S403 and carries out.(be) to enter step S406 under situation about can store.On the other hand, (deny) to enter step S407 under situation about can not store.That is, under storable situation, storing image data in the memory that is determined is carried out printing treatment simultaneously in step S407.

Fig. 7 is the flow chart of the details of the stores processor among the description of step S406.Describe this processing below in detail.In step S701, printing control unit 211 obtains the information in the grouped data from grouped data shown in Figure 10.Below this information is called stored information.

In step S702, printing control unit 211 generates identification id, makes it the processing that is associated with the original image data.This identification id is also referred to as identifying information.In addition, this identifying information and identification id have the information that is used to specify stored original image data and storage purpose ground.Particularly, for example comprise the IP address of compounding machine 120 and be stored in the directory information etc. of the original image data in the storage device in the compounding machine 120.In addition, also can comprise as the address of the printing equipment 110 that carries out the device that PDL handles etc.

In step S703, printing control unit 211 is sent the instruction of transmission and storage identification id and original image data.The instruction of this transmission and storage is to send according to the stored information that obtains at step S701.More specifically say, send original image data and identification ids from printing equipment 110 to compounding machine 120 as the device of storing the original image data through network 130.Then, these original image data of storage in the storage device in compounding machine 120.It more than is the details of the stores processor among the step S406.

After the above-mentioned stores processor, in step S407, synthetic in the regulation zone on the original image data is the identification id image that the basis generates with the identification id, and these composograph data are delivered to Printer Engine 125 and are formed on output with on the paper.In the building-up process of these two data, the identification id image that generates according to identification id is so long as can be identified and can obtain the identification id image of identifying information and get final product when the replication processes of back.For example, can adopt one dimension or various forms such as two-dimensional bar, eletric watermark.The synthetic method of these view data is not limited to any method so long as can obtain the synthetic method of identifying information get final product from the identification id image.

Illustrated above by printing equipment 110 carry out that storage among the step S403 select to be handled and the stores processor of step S406 in identification id generate the situation of processing, but the present invention is not limited to this.For example, can substitute printing equipment 110 by master computer 100 carries out.

The explanation that more than is through with the PDL among the step S301 is handled the following describes the replication processes among the step S302.In the explanation replication process, with in above-mentioned PDL handles, the situation that the original image data are stored in the storage device in the compounding machine 120 is that example describes.

Fig. 8 is the flow chart of the details of the replication processes among the description of step S302.Be described in detail in the situation that the paper original copy that is output in the above-mentioned PDL processing is placed on the document board that is connected in any compounding machine on the network and indicates the replication processes of duplicating below.The compounding machine of carrying out replication processes has and compounding machine 120 essentially identical structures shown in Figure 2.For example, the printing control unit of compounding machine of carrying out replication processes is identical with the printing control unit of compounding machine 120 shown in Figure 2, and the printing control unit of therefore carrying out the compounding machine of replication processes also is endowed label 221.

In step S801, the scanner (not shown) of compounding machine reads the paper original copy, generates paper original image data.

In step S802, printing control unit 221 judges in the paper original image data whether have the identification id image.(be) to enter step S803, and (deny) to enter step S807 under the situation that does not have the identification id image under the situation that has the identification id image.

In step S803, storage (step S803) is extracted in printing control unit 221 requests.In the process that request is extracted, at first, from the identification id image, obtain address, as the catalogue of the interior storage device of the compounding machine 120 of the device of storing image data etc. as the compounding machine 120 of the device of handling storing image data by above-mentioned PDL.Then, according to these information, generate grouped data for example shown in Figure 11.Below under the situation that shows as the identifying information of obtaining image, expression has for example obtained the information that the identification id image that is included in the above-mentioned image is had.Under the situation that shows as the identifying information that to obtain image and identification id, represent to comprise in this image the state that identifying information and this identifying information can be obtained by devices such as for example compounding machines 120.In addition, showing as under the situation that image recognition information and identification id disappear, representing not comprise in this image and comprise identifying information in identifying information or this image but state that this identifying information can not be obtained by devices such as for example compounding machines 120.

Grouped data shown in Figure 11 is the example of the grouped data of generation.This grouped data is recorded and narrated in 1101 and is sent destination-address (as the address of the compounding machine 120 of the device of storage original image data).Record and narrate transmission source address (as the address of the printing equipment 110 that carries out the device that above-mentioned PDL handles) in 1102.Record and narrate order (order of storage is extracted in the expression request) in 1103.Record and narrate storage (catalogue of storage device) in 1104.Record and narrate filename (filenames of original image data) in 1105.

Grouped data shown in Figure 12 is the example of the grouped data returned from the equipment that receives grouped data shown in Figure 11.This grouped data is is also recorded and narrated the data format 1206 of original image data except that the information that grouped data shown in Figure 1 has.

In step S803, printing control unit 221 also sends grouped data shown in Figure 11 through network 130 to the address of the compounding machine 120 of the device of conduct storage original image data.Thus, in the time can communicating, extract request, return grouped data shown in Figure 12 to this device for storage with the device on storage purpose ground.At storage purpose ground device and carrying out under the corresponding to situation of device of replication processes, needn't send grouped datas through network 130, obtain the original image data of being stored in the memory of this device and get final product.Under the situation that can not communicate with the device on storage purpose ground, in grouped data shown in Figure 12, record and narrate for NULL and with it as return information.

In step S804, printing control unit 221 judges according to the order in the grouped data shown in Figure 12 1203 whether the original image data are present in the regulation storage.In result of determination is (to have the original image data) (being) under the extractible situation, enters step S805, and under situation about can not extract (no original image data) (denying), enters step S807.

In step S805, printing control unit 221 is extracted original image data etc. according to grouped data shown in Figure 12 from the storage device as the compounding machine 120 of the device on storage purpose ground.Figure 15 is the flow chart of the details of this processing of explanation.Describe this processing below in detail.In step S1501,, from the device on storage purpose ground, extract view data according to the address of 1201 in the grouped data shown in Figure 12.In step S1502, printing control unit 221 is stored these original image data in HDD124.After finishing, above processing enters step S806.In this step S806, the view data that extracts is formed on output with on the paper by Printer Engine 125.In the view data that is extracted not is under the situation of image data format but intermediate data format, needs certainly to carry out to draw before forming image to handle.

And in step S804, be judged to be under the situation that does not have view data (deny), same with common replication processes, the view data that will scan in step S801 is deployed among the HDD124 of Fig. 1, and the view data that will launch by Printer Engine 125 outputs to (step S807) on the paper.

Like this, by read image and printing output from storage device corresponding to the identifying information in the original copy that is scanned, can export from the PDL data format and draw the high resolution image come, but not the export that generates based on the view data that obtains by scan manuscript.Even if having that original copy is stained, an artificial hand-written information etc., by above-mentioned processing, also can not existed stained and hand-written information, with the same export of original.

More than be system configuration and handling process as prerequisite.The characteristic that describes in detail below in the embodiment of the present invention is handled.

Figure 17 possesses from storage device to take out the image corresponding with scan manuscript and the system construction drawing of the print system of the function of printing.As shown in figure 17, this print system is connected to each other master computer 1701, printing equipment 1702, compounding machine 1703,1705 through networks such as LAN 1704.Master computer 1701 in the print system shown in Figure 17, printing equipment 1702, compounding machine 1703,1705 master computer 100, printing equipment 110, the compounding machine 120 with the print system that uses Fig. 1 and Fig. 2 explanation respectively are identical.

Figure 22 is the basic flow sheet that is used to illustrate the printing treatment process of this print system.Use this basic flow sheet explanation processing procedure below.In print system shown in Figure 17, at step S2201, master computer 1701 generates the PDL data by carrying out drive processes, and sends to printing equipment 1702.Then in step S2202 according to these PDL data, printing equipment 1702 is carried out PDL and is handled, and makes printed matter.Afterwards, in step S2203, the printed matter of making is carried out replication processes.

Use the details of drive processes of the flowchart text step S2201 of Figure 18 below.

In step S1801, the user sets whether read printing utilizing master computer 1701 to generate on the basis of original image data by unshowned driver picture.Then, (being) enters step S1802 under the situation of reading the printing setting by this step S1801, and (denys) to enter step S1803 under situation about not setting.Here read printing be meant on the basis that above-mentioned identification id is synthesized in the original image data, print in, with the original image storage in any storage device.As described later, the paper original copy that is read out printing is retrieved corresponding view data according to identification id from storage device when the compounding machine by this print system duplicates, and this view data is formed on output with on the paper.

In step S1802, the printer driver 202 in the master computer 1701 generates the shading image data.These shading image data enter step S1803 after generating the processing end.Illustrated that below the shading image data that generate in the present embodiment are the situation of image data format, but the present invention is not limited to this, also can be intermediate data format.

In step S1803, printer driver 202 generates the PDL data according to original image data and shading image data.In step S1801, do not read when printing is set and only generate the PDL data according to the original image data.

In step S1804, printer driver 202 sends the PDL data through communication interface part 105 and network 130 to printing equipment 1702.Above processing enters step S2202 after finishing.

Carrying out PDL in step S2202 handles.Do not read at step S1801 under the situation of printing setting, the same with common printer, carry out conventional action of printing.That is, generate intermediate language data, regeneration view data according to the PDL data that received.Then, this view data carried out image processing after, form image in output on paper.On the other hand, in step S1801, read under the situation of printing setting, handle same flow process by the PDL above-mentioned and handle with utilizing Fig. 4.Therefore, the PDL in the present embodiment handles and uses Fig. 4 simple declaration.

In step S401, printing equipment 1702 is received in the PDL data that generate in the master computer 1701 by data reception portion 210 through communication interface part 116.

In step S402, the PDL explanation portion 213 in the printing equipment 1702 receives the PDL data from data reception portion 210, and generates the intermediate language data 214 that is made of shading image data and original image data according to these PDL data.

In step S403, the printing control unit 211 in the printing equipment 1702 is carried out the selection on storage purpose ground (storage purpose ground), generates grouped data shown in Figure 10.The selection on this storage purpose ground is meant the storage device of selecting storage original image data and shading image data.This storage purpose ground is selected to handle and is carried out according to above-mentioned flow chart shown in Figure 5, has illustrated in the above but handle details, therefore is omitted.In above-mentioned selection is handled, relatively select storage purpose ground according to the memory capacity of the size of data of original image data and storage device, but in the present embodiment, relatively select storage purpose ground according to the memory capacity of the additive value of the size of data of the size of data of original image data and shading image data and storage device.

In step S404, the renderer 214 in the printing equipment 1702 is carried out to draw and is handled.Drafting is handled the original image data and the shading image data that are meant middle language data form and is carried out the bitmap expansion, generates the original image data of image data format and the processing of shading image data.

In step S405, the printing control unit 211 in the printing equipment 1702 is judged the original image data and the shading image data of whether storing the image data format that is generated.This judgement is carried out based on the storage selection result of step S403.And, (be) to enter step S406 under situation about can store.On the other hand, (deny) to enter step S407 under situation about can not store.

In step S406, the printing control unit 211 in the printing equipment 1702 obtains stored information from the grouped data shown in Figure 10 that generates at step S403, and the designated store destination.Then, after filename being appended on shading image data and the original image data, be stored to the storage purpose ground of appointment.In addition, in this step S406, shading image data and original image data can be synthesized back storage, also can not synthesize and just stored explicitly.This point is like this too for second embodiment.Stored image appearance is the correspondence image corresponding with identifying information and identification id.In this step S406, the printing control unit 211 in the printing equipment 1702 also generates identification id as view data.As mentioned above, this identification id comprises stored information.

In step S407, the printing control unit 211 in the printing equipment 1702 generate the identification id view data according to identification id, after the identification id view data that generated and original image data synthesize, send to the interior Printer Engine 125 of this printing equipment 1702.By Printer Engine 125, the composograph data are formed on output with on the paper, make the paper original copy.

In step S2203, carry out replication processes.This replication processes is undertaken by the identical flow process of replication processes above-mentioned with using Fig. 8.About the replication processes of present embodiment, use this Fig. 8 simple declaration thus.The following describes on the document board that the paper original copy that will make in above-mentioned PDL handles is placed on compounding machine 1705 and duplicate the details of the replication processes of indication.

In step S801, the scanner 127 of compounding machine 1705 reads the paper original copy, generates paper original image data.

In step S802, the printing control unit 221 in the compounding machine 1705 judges in the paper original image data whether have identification id.Existing under the situation of identification id (is) to enter step S803, and (denys) to enter step S807 under the situation that does not have identification id.

In step S803, storage is extracted in printing control unit 221 requests in the compounding machine 1705.In the process of the request of extracting, generate stored information according to identification id.Then, generate grouped data shown in Figure 11 according to stored information.As mentioned above, record and narrate stored information in this grouped data shown in Figure 11.About this stored information and grouped data shown in Figure 11 then as mentioned above, explanation is omitted.

In this step S803, the printing control unit 221 in the compounding machine 1705 and then to compounding machine 1703 transmissions grouped data shown in Figure 11 as the device on storage purpose ground.Thus, under the situation that can communicate, extract request, return grouped data shown in Figure 12 to compounding machine 1705 at storage with compounding machine 1703 as the device on storage purpose ground.In this grouped data shown in Figure 12, as mentioned above, record and narrate the order (whether original image data and shading image data are present in the storage device) that the return value of request is extracted in stored information and expression storage.

In step S804, according to the order in the grouped data shown in Figure 12 1203, the printing control unit 221 in the compounding machine 1705 judges whether original image data and shading image data are present in the storage of regulation.In result of determination is (to have view data) under the extractible situation (being) enters step S805, enters step S807 under the situation that can not extract (no view data) (denying).

In step S805, the printing control unit 221 in the compounding machine 1705 is read original image data and shading image data according to grouped data shown in Figure 12 from storage purpose ground device.

In step S806, after 2 view data that the printing control unit 221 in the compounding machine 1705 will be read are synthesized, send in the Printer Engine 125.By Printer Engine 125, this view data is formed on output with on the paper.And in step S406, shading image data and original image data have been synthesized under the situation of storage unconnectedly, needn't synthesize in this step S806.For the original image data after synthetic with the shading image data, no longer synthetic identification id view data.This situation in embodiment 2 too.

On the other hand, in step S804, be judged as under the situation that does not have view data and (deny), same with common replication processes, the view data that will scan in step S801 is deployed among the HDD124 of Fig. 1, and the view data that will launch by Printer Engine 125 outputs to (step S807) on the paper.

The situation of carrying out the generation of shading image data in master computer 1701 more than has been described, but the present invention is not limited to this.For example, also can in the printing equipment 110 that receives the PDL data, carry out.In this too for other embodiment.When being to generate the shading image data in the printing equipment 110, do not need the processing of the step S1802 in the step S2201.Nor must in the step S1803 in the step S2201, generate the PDL data according to original image data and shading image data, as long as generate the PDL data according to the original image data.

Step S1804 in the step S2201 is as long as send the PDL data of this generation to printing equipment 110.And, alternately, for example not only after drawing processing, generate the original image data of image data format among the step S404 in step S2202, also need to generate the shading image data.In addition, the generation of shading image data also can be in master computer 1701, not in printing equipment 1702, and carries out in compounding machine 1705.At this moment, do not need the processing of the step S1802 in the step S2201.

Among the step S1803 in step S2201, do not need to generate the PDL data, but as long as generate the PDL data according to the original image data according to original image data and shading image data.Among the step S1804 in step S2201, as long as send the PDL data of this generation to printing equipment 110.In addition, the processing of step S2202, promptly shading image and original image are associated.The original image that storage is not associated with shading image in storage device.And, alternately, for example processing in the step S2203, be in the replication processes, need to generate the shading image data.Specifically, for example judging in step S804 whether the original image data are present in the storage of regulation, is can extract (having view data) under the situation of (being) to enter step S805 in result of determination.

Then, in step S805, when reading the original image data, storage purpose ground device generating the shading image data.Then, among the step S806, after printing control unit 221 synthetic original image data of being read in the compounding machine 1705 and the shading image data that generated, be sent in the Printer Engine 125, make this view data be formed on output with on the paper.

As mentioned above, in first embodiment, when the paper original copy that has added identification id is duplicated in indication, from storage device, read the image corresponding, the shading image data are synthesized to laggard line output on this image with this paper original copy.Perhaps from storage device, read the composograph that has synthesized the shading image corresponding in advance and export this composograph with the paper original copy.Therefore, even if duplicate the export that obtains with common photocopier, diversionary character strings such as " COPY " can be reproduced out for human eye with discerning.Thus, can suppress to cause the behavior of information outflow owing to the duplicate of reading the high image quality of making from storage device.Because therefore additional identification ID not in this export can not be that the printing of reading from storage device is carried out on the basis with this export.Thereby with what kind of photocopier duplicating, the export that obtains all can show diversionary literal.The effect of the above-mentioned inhibition information outflow of so further raising.

Because native system has above effect, even if therefore distribution is read the duplicate of the high image quality of making from storage device, also can suppress this people who is distributed is that the basis makes the information outflow with duplicate.

＜embodiment 2 〉

In the foregoing description 1, on the paper original copy of making by the PDL processing, added identification id, in the export of making, added shading by the replication processes of this paper original copy.

Different therewith, in the present embodiment, the structure of additional identification ID and shading on the paper original copy of making by the PDL processing be described.

The difference (step S407) that is conceived to the processing that processing that embodiment 2 carries out and embodiment 1 carry out below describes.

In the step S407 of embodiment 1, after identification id view data that will generate according to identification id and original image data are synthesized, these composograph data are formed on output with on the paper, and make the paper original copy.

And in the present embodiment, among this step S407, after synthetic identification id view data, original image data and the shading image data, these composograph data are formed on output with on the paper according to the identification id generation, make the paper original copy.

As mentioned above, the export of the high image quality of making after the PDL of present embodiment 2 handles is the printed matter that has added shading image and identification id image.

Thus, except that the effect of embodiment 1, also has the effect that suppresses to cause the behavior of information outflow from the export of this high image quality itself.

When this paper original copy is carried out replication processes, similarly to Example 1, make the duplicate that has added shading image.

＜embodiment 3 〉

In the system of the prerequisite that becomes embodiment 1, handle on the paper original copy make by PDL and only to have added identification id.And, when this paper original copy is carried out replication processes, make duplicate by from storage device, reading image.In this duplicate, add identification id is arranged.

In embodiment 2, on the paper original copy of making by the PDL processing, identification id and shading have been added.And, when this paper original copy is carried out replication processes, make duplicate by from storage device, reading image.Only add on this duplicate shading image is arranged.

Different therewith, in embodiment 3, the changeable shading image that after having added identification id on the paper original copy of making by the PDL processing, whether adds again of user.When replication processes has been added the paper original copy of shading image, make duplicate by from storage device, reading image.Only added shading image on this duplicate.On the other hand, when replication processes is not added the paper original copy of shading image, make duplicate by from storage device, reading image.Only add on this duplicate identification id is arranged.

In embodiment 1 and embodiment 2, the image that is stored in when PDL handles in the storage device only is associated with identifying information.And in embodiment 3, the image that is stored in when PDL handles in the storage device not only is associated with identifying information, but also synthesizes.Therefore, carry out the processing do not carried out among embodiment 1 and the embodiment 2 again.It is as described below that this handles details.

Figure 17 possesses from storage device to read the image corresponding with scan manuscript and the schematic diagram of the structure of the print system of the function of printing.As shown in figure 17, this print system interconnects master computer 1701, printing equipment (printer) 1702, compounding machine 1703,1705 through the network 1704 of LAN etc.In addition, each device specifics in the print system shown in Figure 17 respectively with the master computer 100 of the print system that uses Fig. 1 and Fig. 2 explanation, printing equipment 110 is identical with compounding machine 120.

About basic, the processing procedure of after storage device is read image corresponding to scan manuscript, printing (below cry read printing) in the print system of foundation present embodiment, at first in master computer 1701, implement drive processes (step S2201), then in printing equipment 1702, implement PDL and handle (step S2301), in compounding machine 1705, implement replication processes (step S2203) afterwards.

Here the flow process of the drive processes of description of step S2201.

The user sets whether read printing by driver picture shown in Figure 16 after utilizing master computer 1701 to generate the original image data.The following describes driver picture shown in Figure 16.1600 expression driver picture integral body, the setting regions of the printer that 1601 expressions are printed, the setting regions of 1602 expression printing treatment.In the setting regions 1601 of printer, have a plurality of printers (for example printing equipment 1702) that are used to select to be connected in network 1704 scroll key 1603, print the performance button 1604 of the detailed setting of machine.

Read to have in the setting regions 1602 of printing treatment to be used for making and read printing functionality and effectively read the shading of setting button 1605, shading being additional to the original image data and set button 1606.Set under the invalid situation of button 1605 reading, shading is set button 1606 must be invalid.Reading under the setting button 1605 effective situations, shading is set button 1606 and can be set at effective or invalid.Reading under the setting button 1605 effective situations, identification id is output after being attached on the original image data.Set under the button 1606 effective situations at shading, the shading image data are output after being affixed on the original image data.

Read set button 1605 effectively and shading set under the button 1606 effective situations, export the paper original copy that has added shading image and identification id.When afterwards this paper original copy being carried out replication processes, make duplicate by from storage device, reading image.On this duplicate, only add shading image is arranged.

On the other hand, set button 1605 effectively and shading is set under the invalid situation of button 1606 reading, output has only added the paper original copy of identification id.Make duplicate by from storage device, reading image when afterwards this paper original copy being carried out replication processes.Only add on this duplicate identification id is arranged.

Figure 23 be explanation according to present embodiment, externally generate the flow chart of the process of PDL data in the equipment.At first, in print system as shown in figure 17, take a decision as to whether the setting (step S2301) of reading printing treatment.(be) to judge whether the shading function is effective setting (step S2302) under the situation of consequently reading printing treatment.(being) enters step S2303 under the effective situation of shading function consequently, generates shading information.(denying) enters step S2304 under the invalid situation of shading function.

The shading function is described here.The shading function is the function that the restriction of the lattice point reproduction when utilizing photocopier etc. to duplicate (reading by general scanner) original copy is made, be following image processing function: form the at first sight not eye-catching inhibition pattern that duplicates, for the image that duplicates, suppress (specific) image that pattern forms can clear visual form appearing in one's mind out as duplicating.Among Figure 21, image 2101 is the shading images before duplicating, and image 2102 is by duplicating the image that shading image obtains.In the example shown in Figure 21, the whole appearance of image 2101 (little lattice point part) disappears by duplicating, and only has the appearance (a little bigger part) of " C " in the image to left behind as the image (image 2102) after duplicating.Utilize this point, be used for functions such as anti-tamper more.The establishing method of this shading function can adopt various methodologies, reads original copy by scanner and duplicates and can be used for preventing that the method for duplicating from getting final product so long as expressed, and does not limit its method.

Figure 19 illustrates that the shading information of carrying out generates the flow chart of the details of handling in step S2303.That is, at first, generate shading image data (step S1901).Then as shown in figure 13, the shading image data that will in step S1901, generate be divided into the shading image data 1 that are equivalent to read printing information zone (identification id is in the back by additional zone) and with in addition regional suitable shading image data 2 (step S1902).After above processing finishes, enter step S2304.When showing as the shading image suitable, express length and above-mentioned zone shading image about equally on the both direction in length and breadth with above-mentioned zone.Figure 13 is expression shading information area and the figure that reads an example in printing information zone.

After in step S2303, generating shading information, be created on the application software of moving on the external equipment of master computer 1701 grades, and generate PDL data (step S2304) by the printer driver of current use.In PDL data that step S2304 generates because of in step S2301 and step S2302, whether reading printing functionality and shading function setting for effective different.

At first, to read printing in step S2301 is set at effectively, in step S2302 be (below be called complete effectively set) under the effective situation, comprise original image data, shading image data 1 and shading image data 2 in these PDL data the shading function setting.Be called the additional attribute information of shading and after being generated, also be associated with these PDL data.

On the other hand, will read printing and be set at effectively in step S2301, in step S2302 be (below be called only read printing functionality effectively set) with the shading function setting under the invalid situation, only comprises the original image data in these PDL data.The attribute information of so-called shading non-add also is associated with these original image data after being generated.

On the other hand, will read printing and be set at invalidly in step S2301, in step S2302 be (below be called completely without imitating set) with the shading function setting under the invalid situation, only comprises the original image data in these PDL data.And these original image data do not have related with it attribute information.

Then, be sent in PDL data (step S2305) that step S2304 generate through network 1704 to printing equipment 1702 from master computer 1701 sides such as external equipment such as grade.Afterwards, return the step S401 of processing of the flow chart of above-mentioned Fig. 4, in printing equipment 1702, be received in the PDL data that step S1804 sends.

In step S2301 be that the PDL that carries out under the invalid situation handles (receiving the processing of PDL data to the output printed matter from printing equipment 1702) and to become embodiment 1 described roughly the same as the processing the basic system with the shading function setting.With the image that is stored in storage purpose ground as different being of the processing in the basic system is the view data of the band identification id that obtains by synthetic identification id view data and original image data, and related adding has attribute information in the view data of the band identification id of this storage.

The following describes printing equipment 1702 receives the PDL data and exports printed matter processing before.

At first, be under the full situation about effectively setting, in the printing equipment 1702 at first as the explanation of the order of Fig. 4, the PDL data conversion that will be generated by master computer 1701 external equipments such as grade is an intermediate language data, carry out having illustrated in the flow chart of Fig. 5 that the image storage purpose ground of its details selects to handle, be judged to be under the situation that in printing equipment 1702 (this device), does not have storage, carry out having illustrated in the flow chart of Fig. 6 that the memory scan of its details handles, carry out having illustrated in the flow chart of Fig. 7 the stores processor of its details, carry out the shading image printing.About this processing, describe in detail below.

Before carrying out stores processor, need to generate the identification id view data.In addition, need synthetic original image data, shading image data 2 and identification id view data.As synthetic method, for example enumerate the method for on the original image data, synthesizing shading image data 2 and original image data respectively.In addition, synthetic method of the present invention is not limited to this, can be the synthetic method that illustrates among the step S407 of second embodiment.But, use which kind of synthetic method as opinion, as the step S407 explanation of second embodiment, all need to synthesize so that identification id can be discerned in the replication processes of back.After above processing finishes, in these composograph data of storage, print.When storing, the composograph data are associated with shading image data 2 and with associated attributes information in the above-mentioned PDL data.The picture format that is substituted in the stores processor to be stored also can be to synthesize, draws preceding intermediate language form as the composograph data after drawing.In this case, become the view data that shading image data 1, shading image data 2, identification id view data and original image data etc. are not synthesized.Therefore, when carrying out the replication processes of back, read under the situation of processing, need to export after synthetic these view data.About adding of identification id view data, also can carry out in master computer 1701 sides.

Like this, the image that is printed in printing equipment 1702 is also additional in addition shading image data 2 in the zone that has added the identification id view data, but because the image of printing directly receives printing from master computer 1701 here, so the image of the character string of shading image at first sight not eye-catching (or visual can not identification) state.

Then, only reading under the effective situation about setting of printing, at first, in the printing equipment 1702 at first as the explanation of the order of Fig. 4, the PDL data conversion that will generate in master computer 1701 external equipments such as grade is an intermediate language data, carries out having illustrated in the flow chart of Fig. 5 that the image storage purpose ground of its details selects to handle.Be judged to be under the situation that in printing equipment 1702 (this device), does not have storage, carrying out having illustrated in the flow chart of Fig. 6 that the memory scan of its details handles.Afterwards, carry out in the flow chart of Fig. 7 the stores processor of its details being described, and print.About this processing, its details is described below.

Before carrying out stores processor, need to generate the identification id view data.In addition, need synthetic original image data and identification id view data.After above processing finishes, in these composograph data of storage, print.When storing, need be associated with PDL data associated attributes information.Being substituted in the picture format stored in the stores processor as the composograph data after drawing, can be to synthesize, draws preceding intermediate language form.At this moment, become the view data that identification id view data and original image data etc. are not synthesized.Therefore, when the replication processes of back, read under the situation of processing, need to export after synthetic these view data.About adding of identification id view data, also can carry out in master computer 1701 sides.Like this, the image that is printed at printing equipment 1702 has added the identification id view data, and not additional shading image data.

Then, in printing equipment 1702, at first carry out common printing treatment according to the PDL data that in master computer 1701 external equipments such as grade, generate completely without imitating under the situation about setting.In above processing, the PDL processing of step S202 finishes among Fig. 3.

Then, enter step S2203 and carry out replication processes.Figure 20 is the flow chart of the details of the replication processes that compounding machine 1704 carries out among the description of step S2203.

At first, use scanner 127 scan manuscripts shown in Figure 2, the result of scanning is stored in the temporary realm (step S2001) of RAM123 or HDD124 as storage device shown in Figure 1.

Then, judge in the paper original copy that in step S2001, scans whether stored information (step S2002) is arranged.In decision process, judge in the view data that obtains by scanning paper original copy whether added identification id.Under the situation of consequently having added identification id, have promptly that (being) enters step S2003 under the situation of stored information, and under the situation of additional identification ID not, do not have promptly that (denying) enters step S2008 under the situation of stored information.

In step S2002, have under the situation of stored information (being), store the request of extracting (step S2003).The information that the request of extracting is used according to the information acquisition that comprises in the identification id uses grouped data shown in Figure 11 to carry out.

Then, extract the result who asks according to the storage of step S2003 and investigate whether store view data (step S2004).(being) enters step S2005 under the situation that consequently can extract (promptly storing view data), and (denying) enters step S2008 under the situation of (promptly not storing image data) can not extracting.

Then, judge with corresponding to the view data of identification id, promptly the view data associated attributes information in the storage device of being stored in be shading additional also be non-shading additional (step S2005).(being) enters step S2006 under the additional situation of shading consequently being judged to be.Under the situation that is judged to be non-shading additional (denying), enter step S2009.

Follow the details of description of step S2006.Promptly, the represented equipment in address of the storage purpose ground equipment from Figure 12 shown in 1201 carries out the extraction (step S1501) of view data, through the communication interface part 126 of Fig. 1 with this image data storage in the temporary realm (step S1502) of the HDD124 of this device.Before in storing HDD124 into, at the identification id view data part in this view data, as shown in figure 14, with shading image data 1 overwrite.Thus, can not carry out by the export after this replication processes, use and utilize identification id to read the printing of the function of original copy from storage device.Afterwards, output to (step S2007) on the paper after by Printer Engine 125 view data of storing among the HDD124 being transformed to vision signal.Figure 14 conceptually represents to utilize shading image to cover the figure that reads the printing information zone in the original copy that obtains by replication processes.
