Description

  The present invention relates to a data processing for creating print data and a print processing system for performing printing by adapting a print processing based on the print data to a print medium.

  In a print processing system that performs printing on a print medium, a printing apparatus (for example, a printer) that is responsible for print processing on the print medium is different from a data processing apparatus that is responsible for data creation processing for creating print data to be given to the printer. There are many cases. For example, in general, data processing is performed on a computer to generate print data, and a printer that is communicably connected to the computer receives the print data and executes the print processing.

  For example, in the technique described in Patent Document 1, print data created on a computer is given to a printing apparatus that holds a plurality of sheets of different sizes and types. At this time, in the computer, print data is created by color matching using an ICC (International Color Consortium) profile according to the characteristics of the selected paper, and the printer operation settings such as paper feed conditions are also in accordance with the paper. It is said.

  The above prior art relates to a printer driver that is mounted on a computer and has both a function of creating print data and a function of remotely controlling the operation of the printer. However, in this type of print processing system, there is a case where the data processing apparatus does not have a function of directly controlling detailed operation conditions of the printing apparatus. For example, RIP (raster image processor) software or hardware that specially creates bit map expanded print data does not necessarily have a function of grasping the state of a printing apparatus.

  In such a case, in order to complete printing and obtain a print product with good quality, the target print media must match between the data processing apparatus and the printing apparatus. However, in these apparatuses, since the settings for adapting to the print media are performed individually, it is not guaranteed that the settings regarding the print media match. Therefore, it is desired to establish a management technique that can more reliably match print media settings between the data processing apparatus and the printing apparatus.

  Some aspects according to the present invention have a configuration for solving at least a part of the above-described problems, and the settings regarding the print medium are reliably matched between the data processing apparatus and the printing apparatus, It is possible to obtain a print product having a good quality.

  One aspect of the present invention has a parameter storage unit that stores print parameters, and specifies a print device that executes print processing using a print parameter corresponding to a print medium specified by print data, and the print medium A parameter management device having a recording unit that records the media identification information and the print parameters in association with each other in the parameter storage unit, and media identification information from the parameter management device and processing parameters corresponding to the print medium identified by the media identification information. And a data processing device for creating print data designating print media by media specifying information, and the parameter management device has a history storage unit for storing a processing parameter acquisition history by the data processing device, and a recording unit Is a processing parameter held by the data processing device. Identified on the basis of the information that is stored over the history storage unit, to record the print parameters corresponding to the identified processing parameters in the parameter storage unit, a print processing system.

  In the invention configured as described above, what processing parameter the data processing apparatus acquires and holds from the parameter management apparatus is grasped from the history information stored in the parameter management apparatus. Then, print parameters corresponding to the processing parameters held by the data processing apparatus are recorded in the parameter storage unit.

  Therefore, when the data processing device creates print data using processing parameters corresponding to a specific print medium, the print parameters to be used in combination with the processing parameters are reliably recorded in the parameter storage unit of the printing device. Will be. For this reason, there is no inconsistency between the processing parameters when the print data is created and the printing parameters when the print processing is performed based on the print data, and a print product with good quality can be obtained. it can.

  On the other hand, the parameter management device keeps a history of processing parameter acquisition by the data processing device, so that it can grasp what processing parameters the data processing device acquires and currently holds. Can do. Using this information, it is possible to avoid inconsistencies between the processing parameters held by the data processing apparatus and the printing parameters held by the printing apparatus.

  For example, processing parameters and printing parameters supplied as corresponding to one print medium may be changed afterwards. In such a case, a situation may occur in which the printing parameters of the printing device are updated and the processing parameters of the data processing device are not updated. In the present invention, since the acquisition history of the processing parameters by the data processing device is stored, it is possible to grasp inconsistencies in such a situation, and it is possible to take appropriate measures as necessary. Become.

  As described above, according to the present invention, by matching the processing parameters held by the data processing device with the printing parameters held by the printing device, it is possible to reliably set the print media between the data processing device and the printing device. It is possible to obtain a print product having a good quality by matching.

  According to another aspect of the present invention, a print including a data processing unit that generates print data including information specifying a print medium and a print unit that executes a print process according to the print medium specified by the print data. A printing processing method in a processing system, wherein a parameter management unit that manages processing parameters in data creation processing by a data processing unit and printing parameters in printing processing by a printing unit is provided in the printing processing system, and the parameter management unit is a printing medium Is recorded in the parameter storage unit of the printing unit in association with the print parameter corresponding to the print medium, and is specified by the media specification information and the media specification information according to the access from the data processing unit. Process parameters corresponding to the print media The processing parameter acquisition history is stored in the data processing unit, the processing parameter held by the data processing unit is specified based on the acquisition history, and the print parameter corresponding to the specified processing parameter is stored in the parameter storage unit. Let me record.

  According to another aspect of the present invention, the medium specifying information for specifying the print medium and the medium specifying information are specified in response to an access from a data processing unit that generates print data including information for specifying the print medium. In the parameter transmission unit that transmits the processing parameter corresponding to the print medium to the data processing unit, and the parameter storage unit that the print unit that executes the printing process corresponding to the print medium specified by the print data includes the medium specifying information and the medium The recording unit includes a recording unit that records the print parameters corresponding to the print medium specified by the specific information in association with each other, and a history storage unit that stores an acquisition history of processing parameters by the data processing unit. Specifies the processing parameters held by the system based on the information stored in the history storage unit. The printing parameter corresponding to the process parameters that were to be recorded in the parameter storage unit, a print management device.

  Also in the invention having such a configuration, the processing parameter held by the data processing unit is specified, and the corresponding print parameter is recorded in the parameter storage unit. Therefore, as in the above-described invention, it is possible to avoid inconsistencies between the processing parameters and the printing parameters, to ensure that the settings relating to the print media are consistent between the data processing unit and the printing unit, and to produce a print product with good quality It is possible to obtain

  According to another aspect of the present invention, a print including a data processing unit that generates print data including information specifying a print medium and a print unit that executes a print process according to the print medium specified by the print data. A print management program for managing a processing system, wherein a computer capable of communicating with a data processing unit and a printing unit is associated with media specifying information for specifying a printing medium and a printing parameter corresponding to the printing medium. The data is recorded in the parameter storage unit, and the processing parameters corresponding to the print medium specified by the media specifying information and the media specifying information are transmitted to the data processing unit according to the access from the data processing unit. Stores acquisition history and acquires processing parameters held by the data processing unit Based were identified, and records the print parameters corresponding to the identified processing parameters in the parameter storage unit.

  The functions of the components of the print management apparatus described above can be realized using hardware resources of the computer apparatus. Thus, the present invention can be embodied as a print management program that causes a computer to realize the functions of the print management apparatus. By mounting and executing such a print management program on a computer, in a print processing system having a data processing unit and a printing unit, the settings relating to the print media are reliably matched between the data processing unit and the printing unit, It becomes possible to obtain a print product with good quality.

  In the above invention, for example, the parameter management device has an information acquisition unit that acquires media information according to the characteristics of the print media from outside the print processing system, and the recording unit specifies the processing parameter and the print parameter from the media information, respectively. It may be configured as follows. In such a configuration, it is possible to acquire media information supplied from the outside at any time and apply new processing parameters and printing parameters to the processing. Therefore, it is possible to flexibly cope with changes in specifications of new print media and existing print media.

  The print processing system of the present invention may include a plurality of data processing devices. In this type of print processing system, print data is generally supplied from a plurality of data processing devices to one printing device. In such a case, the processing parameters held by a plurality of data processing devices may not match each other, but by managing the processing parameters as in the present invention, the processing parameters held by each data processing device, It is possible to avoid inconsistency with the printing parameters held by the printing apparatus.

  In this case, for example, the parameter management apparatus may be configured to record all print parameters corresponding to at least one of the processing parameters held by each of the plurality of data processing apparatuses in the parameter storage unit. In such a configuration, even if any of the print media having processing parameters for the data processing device in the print processing system is specified in the print data, the print parameters corresponding to the print media are held in the printing device. Will be. Therefore, the printing apparatus can execute an appropriate printing process using a printing parameter corresponding to the printing medium.

  Further, for example, the parameter management device may be configured not to record in the parameter storage unit printing parameters that do not correspond to any of the processing parameters held by each of the plurality of data processing devices. It is considered that a print medium whose processing parameters are not held in any of the plurality of data processing devices is not specified in the print data created by these data processing devices. Therefore, it is possible to save the storage resources of the parameter storage unit by excluding the print parameters corresponding to such print media from the targets to be recorded in the parameter storage unit.

  Further, for example, the parameter management apparatus may include a reception unit that receives a designation input related to the print medium, and may be configured to acquire media information corresponding to the print medium designated by the input to the reception unit. In such a configuration, the user can specify a print medium in which printing parameters are to be stored in the printing apparatus. In this case, when a new printing parameter is set in the printing apparatus, the data processing apparatus can grasp that the printing parameter has been updated by notification from the parameter management apparatus. Therefore, it is possible to reflect the update of the print parameter in the printing apparatus on the update of the process parameter in the data processing apparatus.

  Note that not all of the plurality of constituent elements included in each aspect of the present invention described above are essential, in order to solve part or all of the above-described problems or a part of the effects described in the present specification. Or, in order to achieve all of them, it is possible to change, delete, replace with another new component, or partially delete the limited content of some components of a plurality of components as appropriate. . In order to solve some or all of the above-described problems or achieve some or all of the effects described in this specification, technical features included in one embodiment of the present invention described above. A part or all of the technical features included in the other aspects of the present invention described above may be combined to form an independent form of the present invention.

  FIG. 1 is a block diagram illustrating a configuration example of a print processing system to which the present invention can be applied. The print processing system 1 includes a personal computer (hereinafter abbreviated as “PC”) 6, a printer 7, and a management server 8, which are communicably connected to each other (Local Area Network; hereinafter referred to as “LAN”). (Abbreviated). More specifically, information terminal devices such as a PC 6, a printer 7, and a management server 8 are connected to a LAN line 5 connected to the Internet communication network 2 as a public communication line via a router (not shown). Each of these information terminal devices may be included in the print processing system 1. Moreover, the connection between each above-mentioned component does not ask | require wired and wireless as long as it can communicate mutually.

  Connected to the Internet communication network 2 is at least one data server 3 that holds various information such as data for properly operating the print processing system 1 and firmware for adding or improving functions. The print processing system 1 can acquire the information by accessing the data server 3 as necessary.

  The PC 6 provided in the print processing system 1 has a hardware configuration similar to that of a general personal computer. That is, the PC 6 includes a CPU (Central Processing Unit) 61 that controls each part of the PC and a calculation process, a memory 62 that temporarily stores calculation data, and a storage 63 that stores and stores control programs to be executed by the CPU 61 and various data. , An interface (IF) 64 responsible for communication with the outside, an input unit 65 for receiving operation input from the user, a display unit 66 for performing various notifications to the user, etc., which are electrically connected to each other To exchange data. One or more PCs 6 are included in the print processing system 1. In particular, in a print processing system including a plurality of PCs 6, the processing of this embodiment has a remarkable effect.

  The printer 7 also has a hardware configuration similar to a general configuration as a network printer. That is, the printer 7 includes a controller 71 that controls each part of the printer and data processing, a printer engine 72 that executes a printing operation on a medium (print medium), a memory 73 that temporarily stores image data, and communication with the outside. Interface (IF) 74, an input unit 75 that receives an operation input from the user, a display unit 76 that performs various notifications to the user, and the like, which are electrically connected to exchange data with each other. . Hereinafter, the printer engine 72 will be described as an inkjet type as an example, but the printing method is not limited to this and is arbitrary. One or a plurality of printers 7 are included in the print processing system 1.

  Note that the printer 7 may have a storage in the same manner as the PC 6 in order to accept large-capacity image data. Further, on the assumption that the user interface is realized on the PC 6, at least one of the input unit 75 and the display unit 76 may be simplified or omitted. Further, the printer 7 may be included in the print processing system 1 as a so-called local printer connected to the PC 6 without going through the LAN line 5 in addition to being included in the system as a so-called network printer.

  The management server 8 has a function of managing the print processing system 1 including various terminal devices connected to each other via the LAN line 5. The configuration is the same as that of a general PC. Specifically, the management server 8 includes a CPU 81, a memory 82, a storage 83, an interface (IF) 84, an input unit 85, a display unit 86, and the like.

  The configuration of the data server 3 can be the same as that of the management server 8, but it may be a server-dedicated machine in which an input unit and a display unit that serve as a user interface are simplified or omitted. Specifically, the data server 3 is provided with a CPU 31, a memory 32, a storage 33, an interface (IF) 34, and the like. As will be described later, this data server 3 is intended to hold data stored therein in a state where it can be distributed through the Internet communication network 2, and functions as such a data disclosure server. It may be a configuration specialized for. The print processing system 1 can access the data server 3 via the Internet communication network 2. There may be a plurality of print processing systems accessible to the data server 3.

  The print processing system 1 is a system for printing an image having contents designated by a user operating the PC 6 on a designated print medium. As an image to be printed, there are various images such as a text image created by document creation software, a graphic image formed by drawing software, a photograph taken by a digital camera, and an image read by a scanner. Also, the print media can be a combination of materials (paper, resin film, cloth, etc.), optical properties (color, transparency, glossiness, etc.) and forms (sheet-fed, roll-shaped, three-dimensional molded products, etc.) There are various things.

  FIG. 2 is a diagram schematically showing the flow of data in this print processing system. Each of the PC 6, the printer 7 and the management server 8 constituting the print processing system 1 and the data server 3 connected to the print processing system 1 via the Internet communication network 2 have the hardware configuration shown in FIG. Each functional block shown in FIG. 2 is realized by hardware or software by executing a control program in which components are created in advance.

  In the PC 6 operated by the user, the CPU 61 executes a program recorded in advance in the storage 63, thereby realizing functional blocks such as the above-described image editing application 601 such as document creation software and drawing software, and the printer driver 602. The When the user desires to print an image edited using the image editing application 601, an operation input for instructing the image editing application 601 to execute printing is performed after designating a print medium to be printed and other printing conditions. , From the input unit 65.

  When the input is accepted, the image data and the setting information regarding the printing conditions are transferred from the image editing application 601 to the printer driver 602. The printer driver 602 is a control program specialized for controlling the printer 7, performs data creation processing based on image data indicating the contents of an image to be printed and setting information, creates print data corresponding to the printer 7, and creates a printer. 7 to send. The data creation processing includes, for example, various data processing such as color conversion processing for expanding RGB-expressed image data into ink raster data (bitmap data), rotation or inversion processing, and gamma correction processing. .

  This data creation processing is processing for creating print data suitable for the designated printer 7 and print media M from image data prepared by the user, and the processing content needs to be changed according to the characteristics of the printer 7 and print media. There is. The printer driver 602 does not require the processing contents to be strictly adapted to each of various types of print media having different characteristics. As a simpler print execution method, processes corresponding to some standard print media are prepared in advance, and the user can select one of them as a print medium. The print data sent from the printer driver 602 to the printer 7 includes raster data for each ink color of the printer 7 and information for designating a target print medium. Processing for causing a printer to print from a PC via a printer driver is known, and will not be described below.

  On the other hand, separately from the above, for example, in order to obtain a higher-quality print product, the image data created on the PC 6 is processed by dedicated software or hardware called a RIP (raster image processor) to obtain print data. There are cases that are created. For example, in a business-use high-quality and large-format printer used in a printing company, it takes a relatively long time (for example, several hours) to create print data. Therefore, a dedicated RIP device is provided separately from the PC 6 normally used by the user. May be installed. This RIP device can be realized, for example, by installing RIP software on a PC.

  FIG. 2 shows an example in which one of the PCs 6 constituting the print processing system 1 connected to the LAN line 5 is used as an RIP dedicated device in which RIP software is installed. Hereinafter, a PC used as a dedicated RIP device is referred to as a “RIP device” and is given a reference numeral 6 a to distinguish it from other PCs 6. A plurality of RIP devices 6a may be provided in the print processing system 1. A plurality of PCs 6, for example, all the PCs 6 in the print processing system 1 may have a function as an RIP device.

  When image data is given from the PC 6 to the RIP device 6 a, the RIP device 6 a creates print data from the image data and outputs it to the printer 7. Therefore, the PC 6 is released from the process of creating print data. In the RIP device 6a, the CPU 61 executes the RIP software recorded in the storage 63, whereby the RIP application 611 operates. The RIP application 611 creates print data by executing data creation processing suitable for the print medium based on the designation of the image data and the print medium given from the PC 6 as indicated by a broken line arrow in FIG. Output to.

  In this case, the RIP application 611 needs to execute data creation processing according to the characteristics of the designated print medium M. There are many types of print media with different characteristics, and it is necessary to set processing parameters in data creation processing according to the characteristics. Actually, there are several types of print media used in one printer 7, and processing parameters necessary for creating print data suitable for these print media are stored in advance as a lookup table (LUT) 612. 62 or storage 63. The processing parameters and LUT 612 will be described in detail later. The RIP application 611 reads processing parameters corresponding to the designated print medium M from the LUT 612 and applies them to the data creation processing. The print data sent from the RIP device 6a to the printer 7 also includes raster data for each ink color of the printer 7 and information for designating a target print medium.

  The controller 71 of the printer 7 that has received the print data controls the printer engine 72 to execute a print process suitable for the designated print medium, and prints an image of the designated content on the print medium M. As a result, a printed product is obtained. Print parameters for executing a print process suitable for the print medium M are stored in a preset LUT 701 in the memory 73, and the controller 71 reads out the print parameters corresponding to the designated print medium M from the LUT 701 for printing. Apply to processing. The printing parameters and LUT 701 will be described in detail later.

  Both the processing parameters applied to the data creation processing in the RIP device 6a and the printing parameters applied to the printing processing in the printer 7 are given from the management server 8 according to the operation of the system administrator who operates the management server 8. Specifically, it is as follows. The data server 3 that can communicate with the print processing system 1 via the Internet communication network 2 is provided with a media list 301 that stores media information unique to the print media for various print media distributed in the market. . The media list 301 can be provided on the storage 33 of the data server 3, for example.

  The media information includes information necessary for adapting the data creation process and the print process to the print medium. Processing parameters and printing parameters used for each of the data creation processing and the printing processing may be stored as part of the media information as they are. More generally, the media information only needs to include information that can uniquely derive the processing parameter and the printing parameter based on the information. Hereinafter, an example in which processing parameters and printing parameters are included as part of media information will be described.

  FIG. 3 is a diagram illustrating an example of a media list. The media list 301 is information necessary for adapting the data creation process in the RIP device 6a and the print process in the printer 7 to the characteristics of the print media. In order to improve the quality of the print product, it is necessary to optimize the processing by the combination of the printer 7 and the print medium M. Therefore, the media information is prepared for each combination of the printer 7 and the print medium M.

  In the example of FIG. 3, print media that are distinguished by the symbols aaa, bbb, ccc,... Are prepared as print media types corresponding to the printer represented by the model number AAA. In addition, as the print media type corresponding to the printer represented by the model number BBB, the print media identified by the symbols aaa, bbb, ddd,... Are also the print media types corresponding to the printer represented by the model number CCC. , Print media distinguished by symbols eee, fff, ggg,... Are prepared. In this way, there are many types of print media on the market, but it is not necessary to prepare media information for all combinations of printers and print media, and each printer type can be used with that printer. It is sufficient that media information is prepared for a print medium that is supposed to be used.

  Media information is created for each possible combination of printer and print media. The media information can include information determined by the type of the print medium due to the characteristics of the print medium and information determined by the combination of the print medium and the printer. As an example of information determined by the type of print media, here, an ICC (International Color Consortium) profile, which is an example of color profile information related to the color development of the print media, is shown. The ICC profile is information for reproducing the color tone of the original image on the print medium with high accuracy in the color conversion process during the data creation process, and has objectivity that is practically standardized in the field of image processing. is there.

  On the other hand, print setting information and mechanical parameters (mechanical parameters) are listed in FIG. 3 as examples of information determined by a combination of a printer and a print medium. The print setting information is information relating to setting of print conditions on the printer side such as resolution and ink color, and indicates print conditions suitable for the print medium among print conditions that can be set by the printer. In addition, the mechanical parameter is information related to the setting on the mechanical surface of the printer for performing good printing on the print medium, such as the conveyance speed of the print medium and the platen gap.

  Of these pieces of information, the ICC profile information and the print setting information are elements to be incorporated in the data creation process by the RIP device 6a, and these are used as process parameters. On the other hand, the mechanical parameter is an element to be incorporated in the printing process by the printer 7 and is used as a printing parameter.

  Thus, the media information includes ICC profile information and print setting information as processing parameters, and mechanical parameters as print parameters. In the media list 301, a set of these information is a combination of a printer and a print medium. It is prepared for each. The media information may further include information other than these. Further, as described above, instead of directly including the processing parameters and the printing parameters, information that can uniquely estimate these parameters may be included.

  In addition, once published media information may be changed afterwards. For example, there is a case where the specification of a print medium is changed, or parameters for improving the image quality of the print medium are improved. Further, for example, there is a case where the parameter needs to be changed as the firmware of the printer 7 is updated. For this reason, media information distributed to the same print media may differ depending on the time. In order to distinguish such different media information, version information is added to the media information listed in the media list 301.

  The media list 301 is provided by, for example, disclosing media information on a combination of a printer supplied by the printer and usable print media on the data server 3 operated by a printer supplier (printer manufacturer or sales company). It can be carried out. Alternatively, the print media supplier may disclose media information about the combination of the print media supplied by itself and the corresponding printer. In another aspect, other third-party organizations may provide media information across a combination of printers and print media supplied from various suppliers.

  The media list 301 may be distributed to users in a state where the media list 301 is recorded on an appropriate recording medium such as a portable memory or an optical disk that can be attached to and detached from the computer. In the aspect in which the media list 301 is made public on the Internet communication network 2 as described above, the user can acquire the media list 301 if there is an Internet connection environment. When there is an addition, abolition, or change, it is easy to reflect in the media list 301, and there is an advantage that new information can be quickly distributed to users.

  Returning to FIG. 2, the description of the print processing system 1 will be continued. In the management server 8, when the CPU 81 executes the control program recorded in the storage 83, each function block such as the information acquisition unit 801, parameter identification unit 802, printer management unit 803, parameter distribution unit 804, history management unit 805, etc. Is realized. Among these, the parameter determination unit 802 and the history management unit 805 are mainly realized by the CPU 801 and the memory 82. Further, the information acquisition unit 801, the printer management unit 803, and the parameter distribution unit 804 are mainly realized by the CPU 801 and the IF 84. Of course, in practice, the above functions are realized in cooperation with the hardware of the management server 8 as necessary.

  The information acquisition unit 801 accesses the data server 3 via the Internet communication network 2 and acquires media information corresponding to the print media used in the print processing system 1 from the media list 301. The parameter specifying unit 802 specifies processing parameters and print parameters based on the acquired media information. When the media information includes processing parameters and printing parameters, information corresponding to the processing parameters and printing parameters may be extracted from the media information. Further, when the media information includes information for deriving a processing parameter and a printing parameter, these parameters can be specified by a predetermined calculation based on the information.

  Among the specified parameters, the print parameters are sent to the printer 7. Specifically, the printer management unit 803 creates a table that describes print parameters corresponding to one or more types of print media used in the printer 7, and stores the table in the memory 73 (or storage) of the printer 7. The LUT 701 is written and stored.

  FIG. 4 is a diagram showing an example of a printer lookup table. In the LUT 701 provided in the printer 7, a media number for distinguishing a plurality of types of print media and a print parameter (in this example, a mechanical parameter) corresponding to the print media specified by the media number are associated with each other. In the media list 301 on the data server 3, individual names representing print media types are used, but in the LUT 701 on the printer 7, the type of print media is specified by a simpler media number.

  As described above, there are many types of print media on the market, but only a few of them can be used with one printer. Also, print media are supplied from many suppliers, and the naming rules are not uniform. For this reason, in order to distinguish several types of print media that can be used by one printer, it is more convenient to manage by a simple code (for example, serial number) rather than using a unique name for each print media. It is. In the example of FIG. 4, print parameters corresponding to 30 types of print media distinguished by numbers 1 to 30 can be stored in the LUT 701.

  A table in which the media number and the print parameters are associated is transmitted from the printer management unit 803 of the management server 8 to the printer 7. Therefore, the management server 8 knows the correspondence between the print parameters stored in the LUT 701 of the printer 7 and the media number. In addition, a “computer ID” can be recorded in the LUT 701 for each media number. This point will be described later.

  Returning to FIG. 2 again, the description of the print processing system 1 will be continued. The processing parameter specified from the media information in the parameter specifying unit 802 is transmitted to the RIP device 6a. Specifically, the processing parameters are distributed from the parameter distribution unit 804 of the management server 8 to the RIP device 6 a having a function of creating print data in the print processing system 1. At this time, a media number for specifying a print medium corresponding to the processing parameter is associated with the processing parameter. This media number corresponds to the media number associated with the print parameter. That is, in the information given to the RIP device 6a and the printer 7, the same media number is assigned to the same print medium. Since the media number associated with the print parameter is managed by the management server 8, the same media number can be assigned to the processing parameter.

  FIG. 5 is a diagram illustrating an example of a lookup table of the RIP device. A plurality of different types of printers may be connected to the print processing system 1, and the LUT 612 on the RIP device 6a can store processing parameters for each printer model number in order to properly use them. Configured. For one type of printer, multiple types of print media are distinguished by the media number, and the numbering rule gives the same media number to the print parameters and processing parameters corresponding to the same print media as described above. That's it.

  ICC profile information and print setting information as processing parameters are associated with each print medium specified by the media number and stored in the LUT 612. In order to clarify the relationship with the information published on the data server 3, unique information representing the type of print media is stored together with the media number.

  It is not necessary for one printer to acquire information on all print media that can be used with the printer. In other words, it is not necessary for the user to acquire all of the media information that is publicly available for the printer to be used, and only for the print media that is actually used, the media information is acquired and processing parameters and print parameters are prepared. It may be. In the media list 301 shown in FIG. 3, print media types corresponding to the printer BBB are aaa, bbb, ddd,..., Whereas in the LUT 612 shown in FIG. 5, the print media types corresponding to the printer BBB are bbb, This is partly different from ddd, hhh,...

  Of course, the contents of the LUT may be partially different among the plurality of RIP devices 6a included in the same print processing system 1. However, the same media number needs to be assigned to the same print medium in one print processing system 1. Note that the timing of updating the LUT in each RIP device 6a does not necessarily match. For this reason, the setting values of the processing parameters corresponding to the same media number may be temporarily different between the updated RIP device 6a and the unupdated RIP device 6a. In order to cope with this, the management server 8 is provided with a history management unit 805. A history of processing parameter transmission from the management server 8 to the RIP device 6 a is managed by the history management unit 805.

  FIG. 6 is a diagram illustrating an example of a history table held by the history management unit. The history management unit 805 has a history table 806 that records a process parameter update history in each RIP device 6 a included in the print management system 1. The history management unit 805 stores processing parameter update histories in all the PCs 6 (RIP devices 6 a) included in the print processing system 1 in the history table 806.

  The history management unit 805 stores an update history of media information in each of the RIP devices 6 a included in the print processing system 1 managed by the management server 8 in the history table 806. That is, the history management unit 805 stores in the history table 806 when the processing parameters corresponding to each media number are updated for each of the RIP devices 6 a included in the print processing system 1. In the history table 806, a computer ID (for example, an IP address) for identifying each RIP device 6a in the print processing system 1, and the date and time when the processing parameter corresponding to each media number in the RIP device 6a was last updated. Is recorded.

  Thus, in this print processing system 1, the processing parameters for adapting the data creation processing in the RIP device 6a to the print media and the print parameters for adapting the print processing in the printer 7 to the print media are: It is specified from media information published for each type of print media on the Internet. More specifically, the management server 8 in the print processing system 1 accesses the data server 3 via the Internet communication network 2 and downloads necessary media information from the media list 301 published on the data server 3. To do.

  The management server 8 specifies processing parameters and printing parameters from the media information, associates the printing parameters with the media number for specifying the printing media, and stores them in the LUT 701 of the printer 7 that executes the printing process. Further, the management server 8 associates the processing parameter with the media number for specifying the print medium, and transmits it to the RIP device 6a that executes the data creation processing. For this reason, the print parameters stored in the LUT 701 of the printer 7 and the processing parameters stored in the LUT 612 of the RIP device 6a are associated with each other via a common media number.

  Therefore, when an image created by the user by operating the PC 6 is processed by the RIP device 6a and printed by the printer 7, it is possible to designate a print medium to be incorporated into the print data by the media number. That is, the media number of the print medium corresponding to the processing parameter used in the data creation process in which the RIP device 6a creates the print data is transmitted to the printer 7 as a part of the print data. Then, the printer 7 performs print processing using a print parameter corresponding to the media number included in the print data. As a result, the type of print media that is the target of data creation processing in the RIP device 6a always matches the type of print media that is the target of print processing in the printer 7.

  If the type of print media that is the target of the data creation process is different from the type of print medium that is the target of the print process, for example, the color of the print product is different from the one requested by the user. In some cases, the desired print quality may not be obtained. In a conventional general print processing system, settings relating to print media are performed by individual user operations on a PC (RIP device) and a printer. For this reason, there is a flaw between the setting on the PC side and the setting on the printer side, and as a result, the print quality desired by the user in the print product may not be obtained. In particular, in the management based on the media number that does not directly represent the type of print media, it is difficult to detect even if the print media specified by the same media number are different between the PC and the printer.

  In the print processing system 1 of the present embodiment, acquisition of media information from the data server 3, specification of processing parameters and print parameters based on the media information, setting of print parameters to the printer 7, and delivery of processing parameters to the RIP device 6a Are all performed by the management server 8 at once. The management server 8 also associates processing parameters, print parameters, and media numbers. For this reason, the setting of the processing parameter in the RIP device 6a and the setting of the printing parameter in the printer 7 are associated with the same print medium by a common media number. Therefore, it is avoided that the target print media differ between the processing in the RIP device 6a and the processing in the printer 7. As a result, it is possible to obtain print products of a quality desired by the user for various print media.

  Hereinafter, operations of each component of the printing system 1, that is, the management server 8, the RIP device 6a, and the printer 7 for enabling the management as described above will be described in detail. The outline of print management in the print processing system 1 is as described above, but in the operation of each unit described below, processing for making the management function function more effectively is added.

  FIG. 7 is a flowchart showing processing in the management server. In this process, the CPU 81 provided in the management server 8 executes a control program recorded in advance in the storage 83 to cause each unit of the management server 8 to perform a predetermined operation specified in the program, thereby managing the system. It is executed according to the user's operation or periodically. This process is a process for updating the LUT 612 provided in the RIP device 6a and the LUT 701 provided in the printer 7 as needed to keep them up-to-date.

  In this process, it is checked whether or not there is a request for changing the registered content by the user, such as new registration of print media to the print processing system 1 or correction of settings (step S101). In this print processing system 1, up to 30 types of print media can be registered in advance using media numbers 1 to 30. In this way, printing on a registered print medium can be executed promptly without requiring new information acquisition. The user may desire to change the registration contents such as newly registering an unregistered print medium, deleting the registered print medium, or updating information on the registered print medium.

  In order to accept such a request, step S101 is provided. The change request can be made, for example, when the user operates the PC 6 and sends a signal to that effect from the PC 6 to the management server 8. Specifically, when the user performs an operation input indicating that the registered content is desired to be changed to the input unit 65 of the PC 6, a corresponding signal is transmitted from the PC 6 and transmitted to the CPU 81 via the IF 84 of the management server 8. The It is also possible for the system administrator to make a change request directly by operating the input unit 85 of the management server 8.

  If there is a change request from the system administrator or user (YES in step S101), the process proceeds to step S104. If there is no change request (NO in step S101), the CPU 81 checks the media list 301 on the data server 3 (step S102).

  The administrator of the data server 3 adds or abolishes print media for publishing media information or updates published information according to the distribution status of each print media. The CPU 81 checks such an update history, and determines whether information has been updated for the registered print media (step S103). If there is an update, step S104 is executed, and if not, step S104 and subsequent steps are skipped.

  In step S104, the media information related to the print media that the system administrator or the user desires to acquire or needs to update among the print media included in the media list 301 published on the data server 3 is downloaded. The target print medium may be one type or a plurality of types. From the media information acquired in this way, the CPU 81 specifies a processing parameter and a printing parameter corresponding to the printing medium (step S105).

  Next, the CPU 81 (history management unit 805) checks the processing parameter acquisition history of each RIP device 6a (step S106). The acquisition history is grasped based on information recorded in the history table 806. That is, if the last update date and time of the processing parameter in each RIP device 6a is later than the previous update of the LUT 701 of the printer 7, it can be said that the processing parameter is the latest in the RIP device 6a.

  There is a possibility that the processing parameter whose last update date is before the previous update of the LUT 701 of the printer 7 is inconsistent with the print parameter updated on the printer 7 side. Since the user may not intentionally perform the update, the forced update is not performed. When there are a plurality of RIP devices 6a on the same system, it is possible that the updated processing parameter and the updated one are mixed in the latest processing parameter. As a result, different processing parameter values for each RIP device 6a compete for the same media number.

  Such a conflict occurs when a change is made to the published media information, and as a result, multiple versions of processing parameters with different contents exist for the same print media. Similarly, when a media number assigned to a certain print medium is assigned to another print medium, contention similarly occurs.

  As a result of checking the parameter acquisition history of each RIP device 6a, when all the RIP devices 6a have been updated to the latest processing parameter (YES in step S107), there is no processing parameter conflict. Therefore, an arbitrary media number can be assigned to a new processing parameter and printing parameter obtained from the media information. The management server 8 accepts a designation input relating to the media number from the system administrator via the input unit 85 (step S108).

  On the other hand, when there is an unupdated RIP device 6a (NO in step S107), there is a possibility that there is a conflict with an updated process parameter that has not been updated. If further updating is permitted, confusion will occur, and therefore the CPU 81 prohibits new allocation for media numbers that have conflicts, and accepts designation input for media numbers that are excluded (step S109). It may be displayed on the display unit 86 that there is a possibility of conflict, and the system administrator may determine whether or not to assign a new parameter to the media number where the conflict has occurred.

  The media number thus designated and the corresponding print parameter are transmitted as update data to the printer 7 (step S106), and the LUT 701 of the printer 7 is updated with the update data. The printer 7 may not be detected in the print processing system 1 because the printer 7 is not turned on or the communication cable is not connected. In this case, when the printer 7 is next detected in the print processing system 1, the update may be performed before the print processing by the printer 7 is executed.

  As shown in FIG. 4, the computer ID can be recorded in the LUT 701. The computer ID is information given to update data transmitted from the management server 8 to the printer 7 as necessary. When there is a process parameter conflict corresponding to one media number among a plurality of RIP devices 6a, all the print parameters corresponding to them are stored in the LUT 701 of the printer 7. That is, even if the processing parameters corresponding to the same media number are different among the plurality of RIP devices 6a, the printing parameters corresponding to the processing parameters of each RIP device 6a are assigned the same media number, and the printer 7 Is saved. This makes it possible for the printer 7 to appropriately perform print processing when print data is transmitted from any RIP device 6a.

  FIG. 8 is a diagram illustrating an example of the contents of a printer LUT when there is a conflict. For example, let us consider a case where a processing parameter assigned with the media number “1” conflicts between an RIP device having a computer ID “XXX” and an RIP device having a computer ID “YYY”. Further, it is assumed that the processing parameter to which the media number “1” is assigned is the latest one in the RIP device “XXX” and the one before the update in the RIP device “YYY”. In this case, as shown in FIG. 8, two rows having a media number “1” are provided, and one of them records the computer ID “YYY” of the RIP device whose processing parameter is not the latest. In the “mechanical parameter” column of the row, the print parameter (before update) corresponding to the processing parameter assigned the media number “1” in the RIP device “YYY” is recorded. In the other line, the latest mechanical parameters are recorded.

  By doing this, both of the two types of printing parameters (mechanism parameters) corresponding to the media number “1” are stored, and the RIP apparatus holding the processing parameters before the update can be identified. . Therefore, even when print data in which the media number “1” is designated is transmitted from any RIP device, the printer 7 can execute print processing using different print parameters according to the transmission source.

  Even when there are conflicts between three or more RIP devices or when there are conflicts between two or more media numbers, the necessary number of rows corresponding to one media number are provided and not updated. The computer ID of the RIP device and the printing parameters corresponding to it are stored individually. The RIP apparatus that holds the latest processing parameters does not need to be distinguished, and therefore does not require recording of a computer ID. Further, when the update process is performed on the RIP device 6a side and the processing parameters become the latest, the row in which the computer ID of the RIP device 6a is recorded in the LUT 701 is deleted. In this way, it is avoided that old print parameters that are no longer used remain in the LUT 701 and waste storage resources. As described above, in the present embodiment, with respect to the processing parameters held in at least one RIP device 6a in the system, the corresponding printing parameters are always recorded in the LUT 701. On the other hand, print parameters corresponding to processing parameters not held in any RIP device 6 a are not recorded in the LUT 701.

  The LUT 701 is preferably updated as follows. The management server 8 acquires the contents of the current LUT 701 from the printer 7, updates the contents using the newly acquired print parameters, and rewrites the LUT 701 of the printer 7 with the updated data. Simply sending new print parameters to the printer 7 may cause confusion when there are a plurality of devices having a function as a management server on the print processing system 1, for example. That is, when the LUT 701 of the printer 7 is updated from each of the plurality of management servers, the information managed on each management server and the LUT 701 of the actual printer 7 may be inconsistent. By reading and updating the current LUT 701 contents, such a problem can be avoided. When there are a plurality of printers 7 in the system, the above processing is executed for each of the printers 7 that need to update print parameters.

  Also, the LUT 612 included in each RIP device 6a in the print processing system 1 is sequentially updated. Not all RIP devices 6a in the print processing system 1 are in operation. Therefore, the management server 8 notifies the update of the processing parameter to each RIP device 6a, and when there is a response from the RIP device 6a that receives this, transmits the update data to the RIP device 6a. .

  FIG. 9 is a flowchart showing the operation of the management server for updating the RIP device. When the LUT 701 of the printer 7 is updated, the management server 8 notifies each RIP device 6a that the processing parameter has been updated (step S201). When there is a response from the RIP device 6a that has received this (step S202), the management server 8 transmits update data to the RIP device 6a (step S203). The update data is data in which processing parameters and the like are written instead of the printing parameters of the LUT 701 updated in the printer 7.

  For the RIP device 6a to which the update data has been transmitted, the parameter acquisition history is updated (step S204). Specifically, in the history table 806, the date and time when the update data is transmitted is recorded in the update date and time column corresponding to the RIP device 6a and the updated media number.

  When there are a plurality of RIP devices 6a in the print processing system 1, the management server 8 sequentially transmits update data to the RIP devices 6a that have responded. This is repeated until transmission to all the RIP devices 6a in the system is completed (step S205). As a result, the contents of the LUT 612 in all the RIP devices 6 a operating in the print processing system 1 correspond to the LUT 701 in the printer 7. Therefore, it is avoided that the target print media are different between the data creation process in the RIP device 6a and the print process in the printer 7.

  FIG. 10 is a flowchart showing data creation processing by the RIP device. This processing is realized by the CPU 61 provided in the RIP device 6a executing a control program recorded in advance in the storage 63 to cause each part of the RIP device 6a to perform a predetermined operation specified in the program. . This process is a process for creating print data by the RIP device 6a and transmitting the print data to the printer 7 to cause the printer 7 to perform the print process.

  The RIP device 6a determines whether or not there is a notification regarding the update of the processing parameter from the management server 8 (step S301). If there is a notification (YES in step 3201), that fact is displayed on the display unit 66. Then, the user is inquired whether to update the processing parameter (step S302).

  When the user inputs an operation for updating, the processing parameter is updated. Specifically, the RIP device 6a requests transmission of update data from the IF 64 to the management server 8 via the LAN line 5, and receives update data transmitted from the management server 8 in response thereto (step S303). ). The LUT 612 is updated with the received update data (step S304). When there is no notification regarding update (NO in step S301), and when the user does not want to update (NO in step S302), steps S303 and S304 are skipped. By updating the processing parameters prior to creating the print data, the latest processing parameters can be used for the data creation processing.

  In the RIP device 6a, image data indicating the image content to be printed is determined (step S305). If the PC 6 and the RIP device 6a on which an appropriate image editing application 601 is installed and image editing work is performed by the user are different computer devices, the RIP device 6a receives the image data created on the PC 6 to receive the image. The data will be confirmed. For example, when the image editing application 601 is installed in a PC that functions as the RIP device 6a, the user operates the image editing application 601 to edit the image, thereby determining the image data.

  Also, the printer 7 to be printed and the print medium to be printed are selected by the user's operation input to the input unit 65 of the PC 6 or the RIP device 6a, and finally accepted by the RIP device 6a ( Step S306). As a result, the data to be collected before the printer 7 performs the printing process is prepared. Determination of image data, selection of the printer 7, selection of the print medium, and update of the LUT are independent processes, and need not always be performed in the order shown here.

  The CPU 61 of the RIP device 6a creates print data using the collected data. Specifically, the processing parameters corresponding to the print medium designated by the user, that is, the ICC profile and the print setting information are read from the LUT 612 (step S307), and printing is performed by raster data creation processing using these processing parameters. Raster data in which an image to be developed is developed for each ink color of the printer 7 is created (step S308).

  Further, the CPU 61 creates print data including the created raster data and a media number indicating the print medium designated by the user (step S309), and transmits it to the printer 7 (step S310). The print data is sent from the IF 64 to the LAN line 5 and received by the IF 74 of the printer 7.

  FIG. 11 is a flowchart showing printing processing by the printer. This process is realized by causing a controller 71 provided in the printer 7 to execute a control program recorded in advance to cause each unit of the printer 7 to perform a predetermined operation defined in the program. This process is a process for causing the printer 7 to receive the print data created by the RIP device 6a and performing the printing process.

  The IF 74 of the printer 7 always accepts access from the management server 8 for updating the print parameter (LUT 701). When access for update is made from the management server 8 (YES in step S401), the controller 71 accepts this and updates the LUT 701 (step S402). As a result, the LUT 701 is updated as needed, and the latest state is always maintained.

  The printer 7 accepts print data transmitted from the RIP device 6a through the LAN line 5 as needed. When the print data is received (YES in step S403), the controller 71 acquires information indicating the media number from the received print data (step S404). The controller 71 refers to the LUT 701 based on the media number.

  If there are a plurality of the same media numbers in the LUT 701, it is determined whether or not the computer ID of the RIP device 6a that transmitted the print data is recorded in the LUT 701. In the RIP device 6a in which the computer ID is recorded in the LUT 701, the processing parameter corresponding to the media number is the one before the update. Therefore, when it is determined from the computer ID recorded in the LUT 701 that the transmission source RIP device 6a holds an unupdated processing parameter (YES in step S405), the printer 7 sends the RIP device 6a. Is notified that the processing parameter is not updated (step S406). As a result, it is possible to notify the user that there is a new processing parameter and to prompt the update. The user can determine whether or not to actually update.

  Further, the controller 71 reads out a print parameter (mechanical parameter) corresponding to the print medium specified by the media number from the LUT 701, and sets operating conditions of each part of the printer engine 72 according to the mechanical parameter (step S407). When the RIP device 6a that is the transmission source of print data has an unupdated processing parameter, the print parameter to which the computer ID of the RIP device 6a is attached in the LUT 701 is applied.

  The printer engine 72 executes a printing operation under the set operating conditions (step S408). Specifically, the printer engine 72 forms a color image formed by superimposing single color images of the respective ink colors according to the raster data included in the print data on the print medium M specified by the media number. Thereby, the printing desired by the user is completed.

  As described above, in the print processing system 1 of this embodiment, when the data creation process for creating print data is executed in the RIP device 6a in order to realize printing suitable for the print medium M, the print media Processing parameters corresponding to the characteristics are applied, and when the printing process is executed in the printer 7, the printing parameters corresponding to the characteristics of the print medium are applied. The print data created by the data creation process is transferred from the RIP device 6a to the printer 7, and the printer 7 executes the print process.

  If the target print media is different between the data creation process in the RIP device 6a and the print process in the printer 7, the print quality desired by the user cannot be obtained. In this embodiment, the print data given from the RIP device 6a to the printer 7 includes a media number as information for specifying the print media. Through this media number, the processing parameters held by the RIP device 6a and the printing parameters held by the printer 7 are associated with each other.

  Specifically, the print processing system 1 is provided with a management server 8, and the management server 8 receives media information relating to necessary print media from the data server 3 that publishes media information specific to various print media. Obtained via the Internet communication network 2. Further, the management server 8 specifies processing parameters and printing parameters from the acquired media information, and these parameters, together with media numbers for distinguishing a plurality of printing media and specifying individual printing media, are used for the RIP device 6a and the printer 7. Send to.

  In the RIP device 6a for creating print data, print data suitable for the print medium can be created by data creation processing using given processing parameters. Further, the printer 7 can execute a printing operation suitable for the print medium by a printing process using given printing parameters. The target print media is the same between the data creation process and the print process. For this reason, in this print processing system 1, it is possible to perform printing with print quality according to the user's request.

  If there is an RIP device 6a whose processing parameters are not updated to the latest, the computer ID of the RIP device 6a and the print parameters before update are associated with the media number separately from the latest print parameters. It is stored in the LUT 701. For this reason, the printer 7 performs print processing using appropriate print parameters for both the print data from the RIP device whose processing parameters are updated to the latest and the print data from the unupdated RIP devices. Can be executed.

  The user of the RIP device 6a can hold the pre-update processing parameters and use the printer parameters as necessary to cause the printer 7 to perform printing. Further, since it is notified that there are new processing parameters for updating, it is avoided that old processing parameters and printing parameters remain in the system simply by forgetting to update.

  As described above, in this embodiment, the print processing system 1 corresponds to the “print processing system” of the present invention, but the entire print processing system 1 can also be regarded as the “print management apparatus” of the present invention. is there. The PC functioning as the RIP device 6a corresponds to the “data processing device” and “data processing unit” of the present invention, and the printer 7 functions as the “printing device” and “printing unit” of the present invention. A memory 73 (or storage) provided in the printer 7 for storing the LUT 701 corresponds to the “parameter storage unit” of the present invention.

  The management server 8 also has functions as a “parameter management device”, a “parameter management unit”, and a “print management device” of the present invention. In the management server 8, the information acquisition unit 801, the parameter distribution unit 804, and the history management unit 805 function as the “information acquisition unit”, “parameter transmission unit”, and “recording unit” of the present invention, respectively. The memory 83 (or storage) that stores the history table 806 functions as the “history storage unit” of the present invention. Further, the IF 84 that receives a signal in response to a user request regarding parameter update corresponds to the “accepting unit” of the present invention. Further, the media number associated with the processing parameter and the printing parameter corresponds to “media specifying information” of the present invention.

  The present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described one without departing from the spirit of the present invention. For example, the print processing system 1 of the above embodiment acquires media information from an external data server 3 via the Internet communication network 2. However, in the concept of the print processing system according to the present invention, such a data server itself may be considered as one of the components of the print processing system.

  Further, for example, in the above-described embodiment, when a print instruction is issued from the RIP device 6a to the printer 7, the created print data is transmitted each time. However, for example, the printer 7 provided with a large-capacity storage can store print data transmitted in the past. In this case, it is also possible to execute printing by transmitting only a control command for executing printing using the print data from the RIP device 6a (or PC 6). In that case, there may be a case where the processing parameter when the print data is created does not correspond to the print parameter held by the current printer 7 due to the parameter update after receiving the print data. When such a state is detected, the printer 7 may be configured to notify the RIP device 6a to that effect. In order to enable this, after receiving the print data, the printer 7 may determine whether or not the print parameter of the media number designated by the print data has been updated. For example, such a determination can be made by comparing the date and time when the print data is received with the update date and time of the print parameter.

  Further, for example, in the above embodiment, a user request for making a new print medium usable in the print processing system 1 is made by a user operation input to the PC 6. Instead of this, or in addition to this, a configuration in which a user operation input is made via the input unit 65 of the RIP device 6a or the input unit (not shown) of the management server 8 may be employed. In a configuration in which media information is acquired by an operation input to the input unit of the management server 8, the input unit functions as the “accepting unit” of the present invention.

  Further, for example, in the above-described embodiment, the management server 8 is provided as a dedicated server for centrally managing processing parameters and print parameters corresponding to the print media in the system. However, as described above, the function as the management server 8 can be realized using a hardware configuration of a general computer device. From this point, software for realizing a function as a management server is mounted on at least one PC 6 that is included in the print processing system 1 and on which the image editing application 601 or the RIP application 611 is mounted. It is also possible to combine functions as a server. In this case, a dedicated management server is not necessary. That is, a program described in the software and a recording medium recording the program are also included in one embodiment of the present invention.

  Further, for example, the data server 3 and the management server 8 in the above embodiment are used exclusively for the purpose of supplying parameters for adapting various processes in the print processing system 1 to the characteristics of the print media. However, other than this, these devices may be provided with functions for providing update information such as firmware of the printer driver and printer 7 and for remotely monitoring consumables such as ink.

  In the LUT 612 of the RIP device 6a or the LUT 701 of the printer 7, the processing parameter or the print parameter is associated with the media number. In addition to this, identification information for managing the parameter update history (here, (Referred to as “update ID”) may be used. As the update ID, for example, time stamp information indicating the time when the management server 8 downloads the media information, the time when the printing parameters of the printer 7 are updated, a numerical value indicating the number of updates, or the like can be used.

  In this case, when the media number is delivered from the RIP device 6a to the printer 7, the update ID is added so that the processing parameter and the print parameter associated with the media number correspond to the same print medium. It becomes possible to confirm whether or not. That is, if the combination of the media number and update ID received by the printer 7 does not match the combination held by the printer 7, the processing parameter and the print parameter are updated at different timings, and any of the parameters May have been changed. For example, when such a state is detected, the processing is stopped or the user is notified, so that it is possible to prevent printing from being executed under inappropriate conditions.

  In addition, the ICC profile information, print setting information, and mechanical parameters listed as print parameters listed as processing parameters in the above-described embodiment are only some examples, and in addition to or in place of these. Various parameters to be set according to the characteristics of the print medium can be used. The “media specifying information” of the present invention for specifying a print medium in the LUT is not limited to the media number as described above, but can be any code or name that can distinguish a plurality of registered print media from each other. Can be used.

  Further, for example, in the print processing system 1 of the above embodiment, the PC 6, the RIP device 6 a, the printer 7, the management server 8, etc. are connected in parallel to the LAN line 5 connected to the Internet communication network 2. From the viewpoint of improvement, and in order to more reliably manage the processing parameters and printing parameters, the print processing system is configured as an intranet in which the LAN line 5 is not connected to the Internet communication network 2, and only the management server 8 has an Internet environment. The structure which has may be sufficient.
