Description

  The present invention relates to a technique for adding additional information to an image and outputting it by color plate or by superimposing all colors.

  In recent years, with the spread of DTP (Desk Top Publishing) and the like, print orderers use their own terminals to edit images input from scanners on computer software and perform page imposition. Editing is no longer unusual.

  In such a printing plate making process, aiming for further efficiency, image setter output for directly outputting the image data with the page imposition to the film, CTP (Computer to Plate) output for directly recording the image on the printing plate, Further, CTC (Computer to Cylinder) is performed in which image recording is performed directly on a printing plate wound on a cylinder of a printing press.

  In this case, once film output or printing plate output is performed only for calibration confirmation, and printing calibration or calibration with other calibration materials causes waste in the film or printing plate, and there are many extra work. There is a problem.

  Therefore, in the process of creating and editing a full digital image by such a computer, a system for directly outputting a color image called DDCP (Direct Digital Color Proof) has been demanded.

  For example, such DDCP records image data with page imposition on a plate-making film with an image setter or the like, or performs a printing operation to directly create a printing plate with a plate setter (hereinafter referred to as CTP), Before performing direct image recording on a printing plate wound on a cylinder of a printing machine with CTC, a DCP (Digital Color Proof) that is a color sample that reproduces this is created and its design, color tone, etc. Used for calibration.

  Further, before creating a DCP using such a DDCP, a small size output of single page image data (image data before page imposition) is performed by a general-purpose printer such as an image output device, and the output It is performed to calibrate the design, color tone, text, etc. of the color comp that is an object.

  As described above, in the printing plate making process, it is common to create and calibrate a color comp or DCP for proofreading a picture, tone, or text to be output by DDCP before performing a printing operation. It is the target.

  In this calibration work, additional information such as date, output condition, and output data name may be added to the image when creating a color lamp or DCP (see, for example, Patent Document 1).

  As shown in (a) of FIG. 10, the output data name and date information are added as additional information to the image in which all colors of CMYK are superimposed. As shown in FIGS. 10B to 10E, this image is generally generated by adding additional information to the K color plate, and the additional information is added to the CMY color plate. Not added.

  By the way, when creating an image in which all the colors of CMYK are overlaid, since each color toner of CMYK is applied to each pixel, the toner may be peeled off or scattered depending on the total amount of applied toner. As a method for solving the toner peeling or scattering, there is a method in which color adjustment is performed on an image so that the maximum total toner amount is within a range where toner peeling or scattering does not occur (see, for example, Patent Document 2). .

JP 2002-358178 A JP 2004-191853 A

  The calibration operation may be performed by outputting an image in which all the colors of CMYK are superimposed and inspecting, or may be output for each of the CMYK color plates and inspecting for each color plate. The additional information adding method shown in FIG. 10, that is, the method of adding additional information only to the K color plate, assumes that the CMYK all-color-superimposed image is to be checked. There is a case where there is no additional information in the CMY color plate, and it becomes impossible to distinguish which data is being checked.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a technique capable of recognizing additional information for each color plate even when an image is checked for each color plate. There is.

  In order to solve the above-mentioned problem, the invention described in claim 1 is an image output system for outputting an image by color plate or by superimposing all colors, and generating additional information to be added to the image Means for adding the additional information to each color plate of the image.

  In order to solve the above-mentioned problem, the invention described in claim 3 is an image output system for outputting an image by color plate or by superimposing all colors, and generating additional information to be added to the image Means, first color adjusting means for adjusting color of image data corresponding to the image for each color plate so as not to exceed a preset maximum total toner amount per unit area of the image, and the preset color adjusting means. Second color adjusting means for adjusting the color of the additional information image data corresponding to the additional information for each color plate so as not to exceed the maximum total toner amount per unit area used for adding the additional information; Adding means for adding the additional information for each color plate at a position common to the color plates of the image based on the image data and the additional information image data.

  In order to solve the above problems, the invention according to claim 5 is an image output method for outputting an image by color plate or by superimposing, and an additional information creating step for creating additional information to be added to the image; And an adding step of adding the additional information to each color plate of the image.

  In order to solve the above-mentioned problem, the invention described in claim 7 is an image output method for outputting an image by color plate or by superimposing, and an additional information creating step for creating additional information to be added to the image; A first color adjustment step for color-adjusting image data corresponding to the image for each color plate so as not to exceed a preset maximum total toner amount per unit area of the image, and the preset additional information A second color adjustment step for color-adjusting the additional information image data corresponding to the additional information for each color plate so as not to exceed the maximum total toner amount per unit area used for adding the image, and the color-adjusted image data And an additional step of adding the additional information for each color plate at a position common to the color plates of the image based on the additional information image data.

  Further, the additional information may be added to a common position in each color plate of the image.

  In the second color adjustment, a maximum toner amount for each color plate may be set in the range of the maximum toner total amount, and color conversion may be performed for each color plate based on the maximum toner amount.

  According to the present invention, depending on an image output technique for outputting an image by color plate or overlapping, additional information to be added to the image is created, and the additional information is added to each color plate of the image.

  Thereby, even if an image is output for each color plate, additional information is added to the image for each color plate. Accordingly, in the inspection for each color plate, the additional information can be referred to in each color plate, and the quality of the calibration work is improved.

  Depending on the image output technology that outputs the image by color plate or by superimposing, creates additional information to be added to the image, and adds the additional information for each color plate at a common position in each color plate of the image, Set the maximum toner total amount per unit area of the image, set the maximum toner total amount per unit area used for adding additional information, and image data corresponding to the image so as not to exceed the maximum toner total amount set for the image Is adjusted for each color plate, and the additional information image data corresponding to the additional information is color-adjusted for each color plate so as not to exceed the maximum total toner amount used for adding the set additional information.

  As a result, the maximum toner total amount can be set separately for the image and the additional information portion, and toner peeling or scattering of the additional information portion can be prevented without affecting the color reproducibility of the image. Therefore, both color reproducibility and reference to additional information can be achieved, and the quality of the calibration work is further improved.

  Also, depending on the technology for adding additional information to a common position in each color version of the image, when the image is output with all colors superimposed, the additional information of each color can be overlapped to prevent blurring of the additional information, and plate inspection can be performed. improves.

  Hereinafter, a preferred embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 3 is a configuration diagram of the image output control apparatus. FIG. 4 is a functional block diagram of the image output control apparatus. FIG. 5 is a diagram showing a display screen for setting image data color adjustment. FIG. 6 is a diagram showing a display screen for adjusting the color of the additional information image data. FIG. 7 is a flowchart showing the image data processing operation. FIG. 8 is a diagram for explaining the image data for each color plate and the additional information image data for each color plate. FIG. 9 is a diagram for explaining an output product in which an image with additional information added for each color plate is output for each color plate, and an output product in which an image is output by superimposing all colors.

  As shown in FIG. 1, the image output system includes at least one image editing terminal 1, image output control devices 2A and 2B and a comp image output device 3 for outputting image data, a CTP RIP 4, The CTP 5 and the DCP image output apparatus 6 are connected via a network. The image output control device 2A is provided before the comp image output device 3, and the image output control device 2B is provided before the DCP image output device 6. The CTP RIP 4 is provided upstream of the CTP 5 and the image output control device 2B.

  The image editing terminal 1 is a computer that performs image editing or imposition work of image data. By image editing or imposition work, additional information explaining the image data such as the data name is attached to the image data. When the image data is described in a page description language such as PostScript including character and graphic layout information and color information, incidental information is written in the image data in the page description language.

  After image editing or imposition, the image editing terminal 1 transmits single-page image data to the image output control device 2A for calibration using a color comp, and the imprinted image data for calibration or printing using DCP is CTP. To RIP4.

  The CTP RIP 4 performs RIP processing on the image data. The RIP process interprets image data described in a page description language and develops image data converted into bitmap data in accordance with the output resolution of the comp image output device 3, CTP5, or DCP image output device 6. This is processing, so-called rasterization. By rasterization, the image data becomes image data in which gradation values for each CMYK color plate are assigned to each pixel.

  The image output control devices 2A and 2B perform image processing by analyzing image data transmitted from the image editing terminal 1 via the network. Image processing includes RIP processing similar to CTP RIP4, halftone processing, creation of calibration image data, and color adjustment that limits the maximum total toner amount.

  The calibration image data is image data of an image in which additional information such as supplementary information and date is added to the image corresponding to the image data transmitted from the image editing terminal 1. When this calibration image data is output for each CMYK color plate, additional information is attached to all the color plate images. That is, the image output control devices 2A and 2B create image data in which additional information is added to each of the CMYK color plate images.

  The comp image output device 3 is a multi-function printer having electrophotographic copying means such as a color laser printer and scanning means such as an image scanner, and printing sheets having different sizes can be output in different output directions (vertically placed). A plurality of paper feed cassettes stored in a horizontal direction), storage means for storing the size and output direction of the recording paper stored in each of the paper feed cassettes.

  The comp image output device 3 outputs a comp image based on the calibration image data transmitted from the image output control device 2A on a sheet by color plates or by superimposing all colors.

  The CTP 5 outputs an image based on the image data transmitted from the CTP RIP 4. The DCP image output device 6 outputs the DCP image based on the calibration image data transmitted from the image output control device 2B on the paper by color plates or by superimposing all colors.

  The general operation of this image output system will be described along the flow of the flowchart shown in FIG. 2 while following the flow of the printing plate making process.

As shown in FIG. 2, the image editing terminal 1 edits image data of a single page and writes incidental information (S101).
The image data in which the supplementary information is written is transmitted to the image output control device 2A, and the image output control device 2A that receives the image data analyzes and processes the image data to create calibration image data (S102). The image output control device 2A that has created the calibration image data transmits the calibration image data to the comp image output device 3.

  Upon receipt of the calibration image data, the comp image output device 3 outputs an image based on the calibration image data to a recording sheet of a corresponding size and output direction, thereby creating a color comp in which the comp image is output. (S103).

  The “color comp” here is a colored finish sample, and the design is in line with the intention of planning / editing by showing the finished image close to the printed material as a dummy for the photos and illustrations on the page. It is created for the purpose of examining whether or not to obtain the consent of the client. That is, when the color comp is output, the print orderer or designer confirms the work results such as character proofing and color proofing (S104).

  Here, when it is confirmed that there is a problem by the print orderer or the designer (S104, No), image editing or the like is performed again at the image editing terminal 1, and the color comp is performed by the comp image output device 3. Is created. Here, when it is confirmed that there is no problem (S104, Yes), the imposition work is performed in the image editing terminal 1 by the operator of the printing company as a client (S105). The “impositioning” here refers to a noble (a number placed at the end of a page so that the page number can be seen when the plate-making film is printed and made into a signature. This is an operation of pasting images such as photographs and illustrations in units of 16 pages, 8 pages or 4 pages according to the size of the paper to be applied to the printing press.

  When the image data subjected to the imposition work is transmitted from the image editing terminal 1 to the CTP RIP 4 by the operator of the printing company, the CTP RIP 4 performs RIP processing on the image data and outputs the image. The control device 2B creates calibration image data from the RIP processed image data. (S106).

  The calibration image data is transmitted to the DCP image output device 6, and the DCP image output device 6 that has received the image data outputs an image based on the calibration image data to a recording sheet of the corresponding size and output direction. DCP is created (S107).

  Then, color calibration of the created DCP is performed by a print orderer or a designer. Here, when it is confirmed that there is a problem (S108, No), after various setting information (in addition to color adjustment, output direction, output size, etc.) is changed in the image output control device 2B. The image based on the calibration image data is output again to the recording paper by the DCP image output device 6 to create a DCP (S107).

  If it is confirmed that there is no problem in the created DCP (S108, Yes), the print orderer or the designer sends the image data from the CTP RIP4 to the CTP6 and receives it. The CTP 5 performs image recording directly on the printing plate (S109). Further, the operator of the printing company performs printing using the printing plate, and performs color calibration of the impositioned image that is the printed matter. If it is confirmed that there is no problem (S110, Yes), the process proceeds to the step of printing the printed material by the printing machine (S111).

  Next, creation of calibration image data based on image data performed in the image output control devices 2A and 2B (hereinafter simply referred to as “control device 2”) will be described in detail with reference to FIGS.

  As shown in FIG. 3, the control device 2 includes a CPU 2a, a RAM 2b, an HDD 2c, a monitor 2d such as a CRT (Cathode Ray Tube) and an LCD (Liquid Crystal Display), an input device 2e such as a keyboard or a mouse or a touch panel, a modem, etc. It is a computer comprised by the communication means 2f.

  The HDD 2c stores an image output program 7 that realizes a function of analyzing and processing image data and generating image data for calibration. The image output program 7 is a program that realizes a function of creating color image-specific calibration image data in which supplementary information is added to an image corresponding to color image-specific image data.

  By executing the image output program 7, the control device 2 displays the display screen on the monitor 2d as needed while temporarily storing the calculation result in the RAM 2b while the CPU 2a performs the calculation, and accepts the input from the input device 2e. Each function is exhibited by communicating with the image output devices 3 and 6 by the communication means 2f.

  As shown in FIG. 4, the control device 2 includes, as functions, an additional information image data creation unit 22, a RIP processing unit 23, a halftone conversion unit 25, a synthesis unit 26, and a color adjustment unit (not shown) configured by the CPU 2a. Prepare. Further, the control device 2 includes image data storage means 21 composed of a RAM 2b or an HDD 2c. The color adjustment unit includes a toner amount adjustment unit 24 and a toner amount setting unit 27 configured by the CPU 2a, and a toner amount adjustment information storage unit 28 when configured by the RAM 2b or the HDD 2c.

  The image data storage unit 21 stores the image data transmitted from the image editing terminal 1. When the image data is transmitted via the CTP RIP4, the CTPK RIP4 stores the image data for each CMYK color plane developed by rasterization from the image data in the page description language. In the case of via the CTP RIP4, the image data storage means 21 stores the accompanying information extracted by the CTP RIP4 during the RIP process together with the image data for each color plate.

  The additional information image data creating unit 22 creates additional information image data including additional information and arrangement position information defining the arrangement position of the additional information for each CMYK color plate. The additional information is supplementary information included in the image data or date information held by the control device 2. As the arrangement information, common information stored in the RAM 2b or the HDD 2c is used. That is, in the additional information image data, the arrangement of the additional information is defined at the common position of each color plate of CMYK. The storage of the placement information may be performed in advance, or the device operator may create the placement information using the input device 2e and store it in the RAM 2b or the HDD 2c.

  The RIP processing unit 23 develops image data for each color plate by interpreting and rasterizing the image data stored in the image data storage unit 21. Further, the additional information image data for each color plate created by the additional information image data creating means 22 is interpreted and rasterized, and the additional information image data for each CMYK color plate converted into raster data is developed. That is, the RIP processing unit 23 rasterizes the image data and the additional information image data separately. In the additional information image data, each color plate includes additional information.

  The halftoning means 25 performs a halftoning process on the image data. The halftoning process is a process for creating image data formed by multi-value halftone dots from rasterized image data. The additional information image data including the character image may be formed into a halftone line.

  The synthesizing unit 26 synthesizes the image data and the additional information image data for each corresponding color plate, and creates calibration image data for each color plate.

  The color adjustment unit includes a toner amount adjustment unit 24, a toner amount setting unit 27, and a toner amount adjustment information storage unit 28. This color adjusting means is a first color adjusting means for adjusting the color of the image data for each CMYK color plate so as not to exceed the maximum total toner amount per unit area of the image corresponding to the image data. 2 is a second color adjusting means for adjusting the color of the additional information image data for each CMYK color plate so as not to exceed the maximum total toner amount per unit area used for adding the additional information corresponding to.

  The maximum toner total amount is set by the apparatus operator using the input device 2e. The maximum total toner amount is a value obtained by adding the maximum toner amounts of the CMYK color plates when the maximum toner amount that can be applied by the color plate alone is 100.

  The toner amount setting means 27 creates image toner amount adjustment information and additional information toner amount adjustment information so as not to exceed the maximum total toner amount, and stores it in the toner amount adjustment information storage means 28. The image toner amount adjustment information and the additional information toner amount adjustment information represent, for example, the maximum toner amount of each of the CMYK color plates to be applied to the recording paper as a percentage, and is a toner amount restriction rate. The sum of the toner limit rates of each color plate is equal to or less than the maximum total toner amount.

  The toner amount adjusting unit 24 performs color adjustment by converting the gradation values of the CMYK color plates of each pixel of the rasterized image data and the additional information image data.

  When the gradation value of each pixel of the image data is converted, the toner amount adjustment information for image is referred from the toner amount adjustment information storage unit 28. When the gradation value of each pixel of the additional information image data is converted, the toner amount adjustment information for additional information is referred to from the toner amount adjustment information storage unit 28. The toner amount adjusting means 24 multiplies the gradation value of each color plate of CMYK by the toner amount restriction rate of each color plate of CMYK and converts it to a new gradation value.

  If the additional information portion is output onto the recording paper with all CMYK colors superimposed, there is a risk that toner of each color will be overlapped by arrangement position information defining the same position, and toner scattering and toner collapse may occur. However, the additional information portion can be output with good visibility by this color adjustment. In addition, since color adjustment is performed separately for the image portion and the additional information portion, the color reproducibility of the image portion and the visibility of the additional information portion are compatible.

  Creation of both toner amount adjustment information of the toner amount setting means 27 will be described in detail with reference to FIGS. The toner amount setting means 27 controls the monitor 2d to display the display screen shown in FIG. On the display screen, a setting item for the maximum total toner amount is displayed as one item for color adjustment setting.

  When the apparatus operator inputs the maximum toner total amount for the image data using the input device 2e, the toner amount setting means 27 sets the toner limit ratio of each color plate of CMYK so as not to exceed the value of the maximum toner total amount.

  The toner amount setting unit 27 stores the set toner limit rate in the toner amount adjustment information storage unit 28 as toner amount adjustment information. For example, if the maximum total toner amount is input as 200, the toner amount restriction rate for each color of CMYK is set to 50%.

  On the display screen shown in FIG. 5, a check box for limiting the toner amount in the additional information portion is displayed under the control of the toner amount setting means 27. When the check box is checked using the input device 2e, the toner amount setting means 27 causes the monitor 2d to display a toner amount adjustment display screen of the additional information portion shown in FIG.

  On such a display screen, items for setting the maximum total toner amount in the additional information portion and setting the toner amount limit rate for each color plate are displayed. When the apparatus operator sets the maximum toner total amount, it is possible to individually set the toner amount restriction rate for each color plate within a range not exceeding the maximum toner total amount. By setting the toner amount restriction rate for each color plate, for example, the visibility of the additional information in the Y (yellow) color plate can be improved.

  Next, the image data processing operation of the control device 2 will be described in detail with reference to FIG. Here, it is assumed that the toner amount adjustment information for image and the toner amount adjustment information for additional information are stored in the toner amount adjustment information storage unit 28 by the toner amount setting unit 27 in advance.

  First, additional information is acquired by the additional information image data creation means 22. The additional information image data creation unit 22 reads the image data stored in the image data storage unit 21. Accompanying information such as a data name included in the read image data is acquired, and date information counted by the control device 2 is acquired. These supplementary information and date information are stored in the temporary RAM 2b as additional information. (S201)

  The additional information image data creating means 22 adds common arrangement position information and color information including a description to be drawn in each color of CMYKK to the additional information stored in the RAM 2b, and the additional information is drawn in each color in CMYK. The additional information image data describing that is created. (S202)

  When the additional information image data is created, the RIP processing unit 23 performs RIP processing of the image data and the additional information image data. First, the RIP processing unit 23 rasterizes the image data stored in the image data storage unit 21, and develops rasterized image data for each CMYK color plate from the image data. Further, the RIP processing unit 23 rasterizes the additional information image data separately and refers to the color information to develop the additional information image data for each CMYK color plate rasterized from the additional information image data. (S203)

  When the image data for each color plate and the additional information image data for each color plate are developed by the RIP process, the toner amount adjusting unit 24 receives the image toner adjustment information and the additional information toner adjustment information from the toner amount setting unit 28. get. (S204)

  When the toner adjustment information for image and the toner adjustment information for additional information are acquired, the toner amount adjusting means 24 for the image data and the additional information image data, the maximum toner per unit area when the respective data is output to the paper. Make color adjustments to adjust the total amount.

  That is, the toner amount adjusting unit 24 recognizes the toner amount limit rate of each color from the image toner adjustment information. The tone value of each color plate attached to each pixel of the image data is multiplied by the toner amount restriction rate, and the image data is adjusted using the derived value as a new tone value. Further, the toner amount adjusting unit 24 recognizes the toner amount restriction rate of each color from the additional information toner adjustment information. The additional information image data is adjusted by multiplying the gradation value of each color plate attached to each pixel of the load information image data by the toner amount restriction rate and using the derived value as a new gradation value. (S205)

  When the color adjustment is performed, the halftoning unit 25 performs a halftoning process on the image data (S206). Note that the halftone line processing may be performed on the additional information image data in parallel with the halftone processing on the image data.

  When the halftone processing is performed on the image data, the synthesizing unit 26 supports the image data and the additional information image data for each color plate so that the additional information is added to each image for each color plate. Then, the image data for calibration is created for each color plate (S207). The order of the operations in S206 and S207 can be changed. When the order is changed, the halftone processing and the network line processing are also performed on the additional information image data portion.

  Data and output products created by this image output system are shown in FIGS. The image data transmitted from the image editing terminal 1 becomes image data of CMYK color plates as shown in FIGS. 8A to 8D by the RIP process. In actual image data for each CMYK color plate, for example, a numerical sequence indicating the gradation value of each color of CMYK is arranged in the order of pixels in a dot sequence, and is mixed in one data.

  As shown in FIGS. 8E to 8H, in the control device 2, the additional information image data creating unit 22 creates additional information image data for each color plate as the additional information creating unit. In the actual additional information image data for each CMYK color plate, for example, a numerical sequence indicating the gradation values of each color of CMYK is arranged in pixel order as dot sequential, and mixed in one data.

  As shown in FIGS. 9A to 9D, each color plate is synthesized by synthesizing the image data for each color plate and the additional information image data for each color plate by the synthesis unit 26 that performs the first step of the addition unit. Calibration image data with additional information attached thereto is created. When this image data for calibration is output for each color plate by the image output devices 3 and 6 that perform the second step of the adding means, additional information is attached to the image of each color plate, and the plate inspection property is improved. . That is, even if any color plate image is viewed, information of image data corresponding to the image can be confirmed.

  Further, as shown in FIG. 9E, when the calibration image data for each color plate is overlaid on all colors and output on one sheet, additional information is added to a common position by the additional information image data creation means 22. Thus, the additional information of each color is overlapped and clear without blurring, and does not hinder the image calibration work.

  When proof image data for each color plate is output on one sheet with all colors superimposed, the toner of each color is applied to the same location, but the toner amount adjusting means 24 as the second color adjusting means Since the color adjustment is performed so as not to exceed the maximum total toner amount in the additional information portion, the occurrence of toner scattering can be suppressed and the workability of the calibration work can be improved.

  The toner amount adjusting unit 24 restricts the maximum total toner amount of the image data as the first color adjusting unit separately from the color adjustment for the additional information image data, so that the visibility of the additional information and the color reproducibility of the image are improved. The quality of the calibration work is improved without affecting it.

  As described above, in the present embodiment, the output control apparatus 2 is provided with the above-described functions by causing the image output program 7 stored in the HDD to be executed. 2 can be stored in a readable storage medium such as an optical disk, a magneto-optical disk (CD-ROM / DVD-RAM / DVD-ROM / MO, etc.), or a magnetic storage medium (hard disk / floppy (registered trademark) disk / ZIP, etc.).
