[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printing work instruction system for instructing a printing work.
[0002]
[Prior art]
Conventionally, digitization and digitization have been advanced also in the printing field. For example, when a printed matter of a color image is created, the color image is read by a color scanner, and image data (CMY data) representing, for example, three colors of C (cyan), M (magenta), and Y (yellow). The color image represented by the obtained image data is edited on the display, and image data representing the edited color image is created. The image data created here is created as image data (CMYK data) representing, for example, four colors of C (cyan), M (magenta), Y (yellow), and K (black). Then, printing is performed by a printing system that obtains a printed material from such image data. In the printing system, for example, a printing plate carrying halftone dot images of four colors represented by CMYK data is created based on the CMYK data, the created printing plate is mounted on a printing machine, and the printing machine uses CMYK4. A printed matter of a color image composed of the halftone dot images is created by a procedure such that the color halftone images are superimposed and printed.
[0003]
There are various types of printing machines, inks, and papers used in such a printing system. For this reason, for example, the color of a printed material corresponding to one CMYK data such as (C, M, Y, K) = (50, 50, 100, 100) is a combination of the type of the printing machine, the type of ink, and the like (hereinafter, Such a combination is known as a printing condition).
[0004]
Therefore, in order to reproduce the color intended for editing a color image on a printed matter, it is necessary to convert the image data according to the printing conditions, and a printing system having a function for performing this conversion has been proposed. ing.
[0005]
The above-described conversion of the image data in accordance with the printing conditions is a conversion similar to the conversion conventionally performed in so-called color matching in which the color of the image read by the scanner is reproduced on the display. This conversion is conversion focused on the color of the image, and is hereinafter referred to as color conversion. In this color conversion, a color profile in which the correspondence between the color of the image (here, the color of the printed material) and the image data is expressed in a LUT (Look Up Table) format or the like is used. A color profile representing the correspondence between the color of printed matter and image data in the printing system is hereinafter referred to as a print profile.
[0006]
[Problems to be solved by the invention]
By the way, in order to perform a print work schedule management in a printing factory or the like, a print work instruction system has been proposed in which a print condition is designated to the print system to instruct the print work. In this printing work instruction system, when a printing work is instructed, it is required to present a printing profile according to printing conditions to the printing system.
[0007]
However, since there are a plurality of options for each element, such as the printer model and ink type, which constitute the printing conditions described above, there are many options as printing conditions. In order to guarantee that the color of the edited color image is reproduced on the printed matter, no matter what printing conditions are selected from among these many printing conditions in the actual printing operation, It is necessary that a large number of printing profiles corresponding to each of the large number of printing conditions be prepared in advance.
[0008]
When such a large number of print profiles are prepared, it is complicated to select a print profile corresponding to the printing conditions employed in instructing the print work from the many print profiles. There is a high possibility that a selection error will occur in the selection operation.
[0009]
In order to avoid such a problem, for example, a form in which only representative print profiles corresponding to some representative printing conditions are prepared is conceivable. In such a form, when the printing operation is instructed, the printing conditions are adopted within the typical printing conditions, or the printing conditions are different from the typical printing conditions. For the above, a print profile selected from the prepared representative print profiles is substituted and presented.
[0010]
However, if the printing conditions are limited to such typical printing conditions, it is a matter of course that the degree of freedom of the printing conditions is narrow and the printing conditions that can be originally executed by the printing system can be specified. There is a risk of disappearing. In addition, when a representative print profile is used instead of being presented, the color of the image obtained by the printing system is shifted from the color of the image intended for editing, resulting in a reduction in the quality of the printed matter.
[0011]
For this reason, it is possible to instruct the printing system to perform a printing operation according to the printing conditions for an arbitrary printing condition, and automatically select a printing profile corresponding to the printing condition from among a large number of printing profiles prepared in advance. A print work instruction system that can be selected is desired, but such a print work instruction system has not been realized.
[0012]
In view of the above circumstances, the present invention provides a printing work instruction system capable of instructing a printing work according to a printing work for an arbitrary printing condition and automatically selecting a printing profile corresponding to the printing condition. The purpose is to provide.
[0013]
[Means for Solving the Problems]
The printing work instruction system according to the present invention that achieves the above object includes an element that stores one or more specific element data for each of a plurality of types of elements representing printing conditions, including elements corresponding to the printing press and printing paper. A data storage unit;

A profile storage unit for storing the print conditions identified by the element data selected for each of the plurality of types of elements,
A work instruction data creating unit for creating work instruction data for instructing a printing work in accordance with printing conditions specified by element data selected for each of the plurality of types of elements from the element data stored in the element storage unit;
A profile assignment unit for assigning a print profile stored in the profile storage unit to the work instruction data created by the work instruction data creation unit based on the printing conditions is provided.
[0014]
According to the printing work instruction system of the present invention, the work instruction data creation unit can create work instruction data corresponding to an arbitrary printing condition, and the profile assignment unit can automatically print a print profile on the work instruction data. Assigned. For this reason, the profile storage unit stores a print profile corresponding to each of various print conditions that can be executed by the printing system, thereby ensuring the degree of freedom of the printing conditions in the printing system. Further, by using the printing profile assigned by the profile assigning unit in the printing system, the color intended for editing the color image is reproduced on the printed matter under an arbitrary printing condition.
[0015]
The printing work instruction system of the present invention includes a color management unit that manages colors so that the printing system prints a color image with a stable color,
A management data storage unit that stores management data representing a color management target managed by the color management unit in association with one or more element data selected from the element data stored in the element storage unit; Prepared,
The color management unit uses the management data stored in the management data storage unit corresponding to the element data that specifies the printing conditions that the printing work instructed by the work instruction data created by the work instruction data creation unit follows. It is preferable to manage colors in the printing system.
[0016]
According to such a preferred printing work instruction system, the color management unit described above manages the color under the management target corresponding to the printing condition, so that the color intended for editing is accurately reproduced on the printed matter. The Rukoto.
[0017]
When the printing work instruction system of the present invention includes such a color management unit, “the profile storage unit uses the colorimeter to measure the color of a color image printed by the printing system as a printing profile. Storing the print profile created based on the colorimetric values obtained
The color management unit manages colors in the printing system using the same colorimeter as the colorimeter.
It is preferable.
[0018]
When the color management unit manages colors using the same colorimeter as that used for creating the print profile, the reproducibility of the color intended for editing is enhanced.
[0019]
In the printing work instruction system according to the present invention, the profile allocating unit is associated with a printing condition that is associated with a printing condition that is the same as the printing condition that the printing work instructed by the work instruction data created by the work instruction data creating unit follows. If the profile is not stored in the profile storage unit, the printing profile stored in the profile storage unit is associated with a printing condition that approximates the printing condition that the printing operation instructed by the operation instruction data follows. It is desirable that the printed profile is found by a predetermined algorithm and assigned to the work instruction data.
[0020]
In the printing work instruction system according to the present invention, although a large number of printing profiles corresponding to a large number of printing conditions can be stored in the profile storage unit, a printing profile corresponding to a printing condition that is unlikely to be employed. It is a waste of storage capacity and creation work to create and store all of them in advance. For this reason, when a printing operation according to a printing condition that is unlikely to be employed is accidentally specified, printing that approximates the specified printing condition from among many stored printing profiles. It is desirable to avoid the above-described waste of storage capacity and creation work by associating the print profile corresponding to the condition.
[0021]

[0044]
Assuming that these data shown in FIGS. 2 to 5 are stored in the database, the description will be continued by returning to FIG.
[0045]
The printing work instruction system 10 shown in FIG. 1 stores a color management device 120 that performs color management and creation of a color profile (printing profile) for the printing system 20, and a print profile created by the color management device 120. Manages a profile database 141, a target profile database 142 that stores a target profile that represents a color to be reproduced on a printed material, an order management system 150 that manages print orders, a schedule of a printing press 250 in the printing system 20, and the like.

[0047]
When a profile is created by the profile creation unit 122, a profile creation print 131 on which a predetermined color chart is formed is created by the printing machine 250, and the color patch color of the color chart is measured by the colorimeter 121. Measured color. Based on the colorimetric values obtained by the colorimetry in this way, a print profile corresponding to the printing conditions when the color chart is formed is created and stored in the profile database 141. The profile database 141 is an example of a profile storage unit according to the present invention. In the present embodiment, a print profile and a print condition are associated with each other and stored in the profile database 141.
[0048]
FIG. 6 is a diagram illustrating an example of data stored in the profile database 141.
[0049]
The profile database 141 stores a profile data table 700 that represents the correspondence between print profiles and printing conditions in a list format. Each row of the profile data table 700 represents a correspondence between a printing condition and a printing profile.
[0050]
The profile data table 700 includes, as data items, a profile ID 701 for distinguishing print profiles from each other, a name 702 given to the print profile represented by the profile ID, and a paper ID stored in the paper database 112 described above. The paper ID 703 selected from the above, the ink ID 704 selected for each of the four colors of ink indigo red and yellow from the ink IDs stored in the ink database 113 described above, and stored in the printer database 111 described above. The printing machine ID 705 selected from the existing printing machine IDs, the front / back distinction 706 (printing on the front side during single-sided printing), whether the printing is front side printing or back side printing in double-sided printing, printing conditions, And other data items 707 related to the profile.
[0051]
Here, the printing conditions referred to in the present invention are specified by the data items from the paper ID 703 to the printing press ID 705, and these data items are stored in the operator when the printing profile is created by the profile creation unit 122 described above. Thus, the printer data table 300 of the printer database 111, the paper data table 400 of the paper database 112, and the ink data table 500 of the ink database 113 are referred to and selected from these data. The front / back distinction 706 is also input by the operator, but in the present embodiment, the front / back distinction 706 is positioned as an auxiliary element for further subdividing the printing conditions referred to in the present invention, and is stored in the database. Not recorded.
[0052]
In FIG. 6, a character string such as “profile A” is illustrated as the name 702 of the print profile, but in this embodiment, the format “printing machine number_front / back_paper type name_ink information” is used. A name 702 is created. Here, “printing machine number” is cited from the printing machine data table 300 of the printing machine database 111 based on the printing machine ID 705 selected as described above, and “front and back” is the above-described front / back distinction. 706 is copied as it is. The “paper type name” is quoted from the paper data table 400 of the paper database 112 based on the paper ID 703 selected as described above, and the “ink information” is selected as described above. This is quoted from the ink data table 500 of the ink database 113 based on the ink ID 704.
[0053]
In this way, the profile database 141 stores the print profile created by the profile creation unit 122 of the color tone management apparatus 120 shown in FIG. 1 in association with the printing conditions.
[0054]
By the way, when the color of the printing press 250 is managed by the color management unit 123 of the color management device 120 shown in FIG. 1, the color of the normal printed material 260 is printed on an area outside the printed material 260. The solid color patch of the color tone management printed material 132 formed with a series of solid patches is measured by the colorimeter 121. Then, the density of the solid patch is calculated from the colorimetric values obtained by the color measurement in this way, and the printing press is adjusted so that the density approaches the management target density acquired from the management density database 113 as described later. The color of the printing press 250 is managed by adjusting the ink supply amount in 250. Since the colorimeter for managing the color and the colorimeter for creating the print profile are the common colorimeter 121, the color reproduction accuracy in the printed matter is high.
[0055]
The ink supply amount in the printing machine 250 is adjusted independently at each location corresponding to each of a number of supply tools called ink keys arranged in a direction perpendicular to the direction in which the printing paper passes through the printing machine 250. A series of solid patches on the color management printed matter 132 is created in a number corresponding to the ink keys in a direction perpendicular to the direction in which the printing paper passes through the printing machine 250. The color tone management unit 123 adjusts the ink supply amount by controlling each of the many ink keys so that all solid patches in each set approach the management target density. In this way, the ink supply amount is adjusted and the solid patch density is stabilized, so that the color of the printed matter is also stabilized.
[0056]
The creation of work instruction data for instructing a printing work by the printing system 20 in which colors are managed in this way will be described below.
[0057]
In the order management system 150 described above, an order information input unit 151 is operated by an operator, and information on a printed matter received from a customer is input. Here, an order number is uniquely assigned to each received printed matter, and the number of printing plate sets necessary to create the printed matter is obtained, and printing work (job) for each set of the printing plates is obtained. A unique job number is assigned.
[0058]
Further, in the printing press management system 160 described above, the printing press schedule input unit 161 is operated by an operator, and printing conditions for executing the printing operations (jobs) described above are input.
[0059]
The data input by the order management system 150 and the printing press management system 160 is stored in the work instruction database 170 as work instruction data for instructing each job to the printing system 20.
[0060]
FIG. 7 is a diagram illustrating an example of data stored in the work instruction database.
[0061]
The work instruction database 170 stores a work instruction data table 800 that represents each job in a list format. The work instruction data table 800 corresponds to the work instruction data according to the present invention.
[0062]
The work instruction data table 800 includes, as data items, an order number 801 assigned to an ordered print, a job number 802 assigned to each job, and a paper ID stored in the paper database 112 described above. From the ink ID stored in the ink database 113 described above, the ink ID 804 selected for each of the four colors of indigo red and yellow, and stored in the printer database 111 described above. In the profile database 141, the printer ID 805 selected from the printer IDs, the front / back distinction 806 (printing on the front side during single-sided printing), which is front side printing or back side printing in double-sided printing, and Profile ID 807 for specifying the stored print profile, and target profile A target profile ID808 identifying a target profile stored in the yl database 142, a customer information 809 concerning the customer who orders a print, and an additional information 810 about the job.
[0063]
Among the data items of the work instruction data table 800, the data items from the order number 801 to the paper ID 803, the target profile ID 808, and the customer information 809 are input by the order management system 150. Of the data items in the work instruction data table 800, the data items from the ink ID 804 to the front / back distinction 806 are input by the printing press management system 160. The profile ID 807 is automatically assigned as described below.
[0064]
The profile automatic assignment device 180 shown in FIG. 1 searches the profile data table 700 stored in the profile database 141 for each stage of the work instruction data table 800 stored in the work instruction database 170 to obtain the paper ID, ink When a stage in which the ID, the printing press ID, and the front / back distinction are all found is found, the profile ID described in that stage is written in the work instruction data table 800. As a result, the print profile is automatically assigned to the work instruction data. Therefore, even if a large number of print profiles are stored in the profile database 141, there is no need to find a desired print profile from among the large number of print profiles. By preparing an appropriate printing profile, it is possible to cope with changes in printing conditions in detail. In addition, when an operator who creates work instruction data instructs printing conditions by referring to data stored in the printing press database 111, paper database 112, or ink database 113, the correspondence between the printing profile and the printing conditions. Printing conditions can be specified freely without being aware of the relationship.
[0065]
The work instruction data is stored in the work instruction database 170 in such a state that the print profile is assigned as described above, and the printing system 20 refers to the above-described work instruction data table 800 and executes the printing work. In the RIP system 220 of the printing system 20, color conversion is performed using the printing profile and target profile specified by the profile ID 807 and the target profile ID 808 described in the work instruction data table 800. A color image will be created. In the proofreading machine 270, the printed material specified by the profile ID 807 is used to reproduce the printed material, so that the color of the image on the printed material is accurately reproduced.
[0066]
Further, the above-described work instruction data table 800 is referred to by the color management unit 123 of the color management device 120, and the management density corresponding to the combination of the paper ID 803 and the ink ID 804 is acquired from the management density database 113, and the ink described above. Used to adjust the supply amount. For this reason, an appropriate management density according to the type of paper or ink is used to produce a high-quality printed matter.
[0067]
By the way, although a large number of printing profiles are stored in the profile database 141, storing a large number of printing profiles to completely cover the printing conditions is rarely a waste of storage capacity and profile creation. For printing conditions that are not adopted, it may be considered to omit creation and storage of a printing profile. In that case, it is also conceivable that the printing condition corresponding to the omitted printing profile happens to be adopted when the work instruction data is created. Therefore, in this embodiment, when a print profile corresponding to the same print condition as the print condition specified by the work instruction data is not stored, the profile automatic assignment apparatus 180 performs printing that approximates the specified print condition. A print profile corresponding to the condition is selected from the stored print profiles and assigned to the work instruction data.
[0068]
FIG. 8 is a flowchart showing a selection procedure for selecting a print profile corresponding to the approximate printing condition.
[0069]
In the selection procedure shown in FIG. 8, scoring is performed for each printing profile stored in the profile database 141, and a printing profile with a high score is adopted as a printing profile corresponding to the approximate printing conditions.
[0070]
When the selection procedure shown in FIG. 8 is started, the paper type for the printing conditions corresponding to an arbitrary printing profile among the printing profiles stored in the profile database 141 and the printing conditions specified by the work instruction data are determined. Are matched (step S101). If they match, two points are added (step S102). Next, it is determined whether or not the paper brands match for the two printing conditions described above (step S103). If they match, one point is added (step S104). Next, it is determined whether or not the difference in target density is ± 0.1D or less for the two printing conditions described above (step S105). If they match, two points are added (step S105). S106). Further, it is determined whether or not the ink information matches for the two printing conditions described above (step S107). If they match, one point is added (step S108).
[0071]
Thereafter, it is determined whether or not the scoring has been completed for all print profiles stored in the profile database 141 (step S109). If the scoring has not been completed, for example, the profile ID 701 in the profile data table 700 is set. The above scoring is repeated with reference to the printing conditions of the next printing profile in the order shown. When the above scoring is completed for all the print profiles (step S109: YES), the print profile with the highest score is extracted (step S110). If one print profile is extracted at this point, that print profile is selected and the selection procedure ends.
[0072]
When a plurality of printing profiles are extracted in step S110, the printing machine type is then determined for the printing conditions corresponding to an arbitrary printing profile of the plurality of printing profiles and the printing conditions specified by the work instruction data. Are matched (step S111). If they match, one point is added (step S112). Next, it is determined whether or not the machine numbers of the printing presses match for the two printing conditions (step S113). If they match, two points are added (step S114). Furthermore, it is determined whether or not the front / back distinction is the same for the two printing conditions (step S115), and if they are the same, two points are added (step S116).
[0073]
Thereafter, for all the print profiles extracted in step S110, it is determined whether or not the scoring of steps S111 to S116 has been completed (step S117). Scoring is repeated. When scoring is completed for all the extracted print profiles (step S117: YES), the highest-scoring print profile is extracted (step S118). If a plurality of print profiles are extracted even at this time, the print profile with the latest created date is selected (step S119), and the selection procedure ends.
[0074]
By such a selection procedure, an appropriate print profile is associated with the work instruction data.
