Description

  The present invention relates to a proof creation system and a proof creation method for creating a proof for plate inspection.

  Conventionally, in the printing process, a proof (color proof) is separately prepared for proofreading a color print, and the finished product is confirmed in advance before a production printing plate is prepared. For this reason, multi-valued image data is halftoned by a front device such as a halftone image data generation device to generate binary image data, and a color proof (calibration product) is produced by a color proof creation device based on this halftone image data. (See, for example, Patent Document 1 below).

  When creating such a color proof, the front apparatus or the color proof creating apparatus has a plurality of output conditions in advance, and the image data of the proof to be created and the output condition selection information are transferred from the front apparatus to the color proof creating apparatus. So I was creating a color proof.

The proof created as described above cannot guarantee the consistency between the proof itself and the output copy when a proof copy necessary for each process is created and output after a lapse of time. In the past, proofs were managed with management forms and could be confirmed indirectly.

  The other rotating shaft 14a of the drum 10 is connected to the suction blower P1. A large number of suction holes 31c are formed on the surface of the drum 10 so as to extend linearly in the direction of the rotation axis. The inside of the drum 10 is depressurized by driving the suction blower P1, and the photosensitive paper is sucked onto the surface of the drum 10. .

  The optical unit 16 is configured to be movable in parallel with the drum axis by the sub-scanning unit 17, and performs image writing by exposing the photosensitive paper adsorbed to the drum 10 with a light beam. As shown in FIG. 3, the optical unit 16 includes an LED unit 320, an LED unit 321, and an LED unit 322 as light sources having different three wavelengths. Each LED unit 320, 321, 322 includes a light emitting diode (LED) disposed on a substrate for a plurality of channels, and the light beam from each LED unit 320, 321, 322 passes through mirrors 325, 326, 327. Thus, the image is exposed from the condenser lens 331 onto the photosensitive paper on the drum 10. The exposure shutter 332 is opened / closed by an exposure solenoid 333 to open / close the optical path at the start / end of exposure.

  The plurality of LED units 320, 321, and 322 are configured to emit light of, for example, B (blue) having a wavelength of about 450 nm, G (green) having a wavelength of about 540 nm, and R (red) having a wavelength of about 650 nm. When a silver salt color photosensitive material is exposed by each LED unit, Y (yellow) is developed by B, M (magenta) is produced by R, and C (cyan) is produced by G.

  The optical unit 16 is fixed to a moving belt 340 and guided by a pair of guide rails 341 and 342 so as to be movable in the sub-scanning direction H parallel to the drum axis and in the opposite direction H ′.

  As shown in FIG. 3, the suction blower P1 sucks the inside of the drum 10 through the suction connecting pipe 51 'by an air suction pump, and negatively pressurizes the inside of the drum 10 before the exposure unit 11 starts the exposure, thereby adsorbing the photosensitive paper to the outer peripheral surface. To do.

  In addition, for proof reproduction, information necessary for the output is encoded and stored in an image such as a corner of the proof, but as shown by the broken line in FIG. A reading unit 70 for reading information necessary for output from the coded image of the proof is arranged on the upper part of the apparatus 1.

  Next, the flow of image data and the control system in the color proof creating apparatus 1 shown in FIGS. 2 and 3 will be described with reference to FIG. FIG. 4 is a block diagram of the flow of image data in the exposure unit 11 of the color proof creating apparatus 1 of FIGS. 2 and 3 and the control system of the color proof creating apparatus 1.

  As shown in FIG. 4, the exposure unit 11 includes an image data I / F unit 52 to which YMCK binary halftone image data from the halftone image data generation apparatus 100 of FIGS. A data buffer 53 composed of a hard disk storage device or the like that temporarily stores halftone dot image data from the F unit 52 and outputs it as needed, and a light source driving value for the YMCK binary halftone dot image data from the data buffer 53 are associated with each other. Corresponding to the LED units 320 to 322 of B, G, and R that convert the digital signal of the exposure data from the look-up table 54 into an analog signal. Each LED unit is obtained by analog signals from a plurality of D / A converters 55a, 55b, and 55c and D / A converters 55a to 55c. Comprising a plurality of drivers 56a in direct analog modulation drive each LED of Tsu bets 320-322, 56b, and 56c, a.

  4 includes a central processing unit (CPU) or the like, and receives a read signal from the reading unit 70. The control unit 50 receives the image data I / F unit 52, the data buffer 53, the lookup table 54, and the display unit 2. And control other device parts.

  Further, the control unit 50 stores the density-exposure amount table 60 and the color correction table 61 in the memory. The density-exposure amount table 60 is a table of the exposure amount with respect to the color density on the photosensitive paper, and stores the characteristics of the recording material. For example, the density-exposure amount table 60 changes whenever the lot or type of the photosensitive paper changes. The color collection table 61 is a table for adjusting the color according to the printing conditions such as the color of the printing plate ink, and changes whenever the printing conditions such as the printing plate ink change. The color correction table 61 may be set in the halftone image data generation device 100 on the front device side.

  Before the exposure, the control unit 50 converts the color density set in the input binary halftone image data into an exposure amount by using the density-exposure amount table 60 to correct the light source drive value, and also by using the color correction table 61. The light source driving values are corrected for color adjustment, and these corrected light source driving values are set in the lookup table 54 for each exposure in association with each image data. Then, image formation is performed by exposing the photosensitive paper held on the outer peripheral surface of the drum 10 from the LED units 320 to 322 driven by the drivers 56 a to 56 c according to the exposure data from the lookup table 54.

  The above-described color proof creating apparatus 1 includes a first table such as a look-up table 54 that includes apparatus-specific differences such as exposure light amount, and a second table unique to the proof creating system 101 such as photosensitive material type and sensitivity index. There is a third table having a difference regarding a printing machine or the like downstream of the proof creation device 1 such as the color collection table 61. However, when creating a color proof, the color proof creation device 1 transfers the transferred image. Output is performed by multiplying the data with the data of the first to third tables. Therefore, in order to create a proof copy, information such as a job ticket and an image data storage destination for referring to image data that can be recognized on the front device side (halftone dot image data generating device 100) (proof creation system 101). If the other conditions are not fixed, the latter two types of second and third tables used on the apparatus side are required.

  Next, the operation when creating a proof copy in the proof creation system 101 of FIG. 1 will be described with reference to the flowchart of FIG.

  First, data that has undergone raster-image conversion processing by RIP2 in FIG. 1 is input to the image data generation apparatus 100, and binary halftone image data is generated by the image data generation apparatus 100 (S01). At this time, information necessary for outputting a duplicate of the proof is input to the image data generation apparatus 100, thereby generating image data in which the information is coded (S02).

  As described above, the information to be encoded necessary for outputting a proof copy includes image information such as a delivery destination of the proof copy and the output conditions of the color correction table 61 and the like. Two types of information (including information obtained from devices other than the proof creation system 101) and information generated in the color proof creation device 1 such as the look-up table 54 and the density-exposure amount table 60 in FIG. There is. In addition, since the second and third tables refer to management information such as a job ticket after referencing the code and may be used in association with the management information, the information to be coded is generated on the front device side. In some cases, only information (including information obtained from devices other than the proof creation system 101) is included.

  Next, the binary halftone dot image data and the coded image data are transferred to the color proof creating apparatus 1 and exposed to the photosensitive paper as described above based on the binary halftone dot image data (S04). Next, the exposed photosensitive paper is developed and output as a proof (S05).

  A schematic diagram of the proof is shown in FIG. 7. In the proof P, the proof image G is formed in the central region, and information is coded at a corner of the proof P and around the proof image G. A stored coded image C is formed.

  Next, if a duplicate of the proof is not necessary and there is image data for creating the next proof, the process returns to step S01 (S06).

  When a copy of the proof P is required (S06), it is necessary for outputting the copy from the coded image C of the proof P in FIG. 7 by the reading unit 70 in FIGS. The information is read (S07).

  Next, the photosensitive paper is exposed based on the read information and binary dot image data (S08), and the exposed photosensitive paper is developed and output as a proof copy (S09).

  According to the operation of FIG. 6 described above, when information necessary for outputting a duplicate is formed as a coded image C in the proof P as shown in FIG. The information necessary for output is read from the coded image C of P, and a proof copy is created based on the read information and the image data at the time of creation of the proof P. Therefore, the proof with guaranteed image data and output conditions You can make a copy of

  Conventionally, in the printing process, the proof is (1) color confirmation up to the previous process (for example, confirmation of color / arrangement of character size, font, image data, etc.), (2) confirmation application to the client of the printing, (3 ) Samples for printing printed materials are used in this order, and the latest output is reused in the order of (1) → (2) → (3) or proofed when moving to the next item. Although the process before the front device is related by job ticket (work instruction) information, etc., the copy of the data is created, and the relationship between the two is due to the difference in the medium of digital data and output. When a color proof copy is made after a lapse of time, consistency between the proof itself and the output copy cannot be guaranteed. Whereas it was managed and confirmed indirectly In this embodiment, information necessary for output of the duplicate is formed in advance on the proof as a coded image, and when the proof copy is created, the coded image is read, so the output conditions are guaranteed. Proof copies can be output. In addition, the dot image data can be consistent by using the data stored in the dot image data generation device 100. However, when creating a duplicate, the data from the RIP 2 in FIG. It may be newly generated based on the above.

  Next, another operation when creating a proof copy in the proof creation system 101 of FIG. 1 will be described with reference to the flowchart of FIG.

  First, binary halftone dot image data is generated by the image data generation device 100 (S11). At this time, the reading unit 126 of FIG. 5 of the image data generation device 100 duplicates the coded image C of the proof P of FIG. Information necessary for the output of the object is read (S12).

  Next, the generated binary halftone dot image data and the read information are transferred to the color proof creating apparatus 1 (S13), and based on these, the photosensitive paper is exposed (S14), and the exposed photosensitive paper is developed. Then, it is output as a proof copy (S15). The read information can be transferred, for example, as an accompanying information method for halftone image data.

  According to the above-described operation of FIG. 8, when outputting a proof copy, the reading unit 126 of FIG. 5 of the image data generation apparatus 100 outputs the copy from the encoded image C of the proof P of FIG. 7. Since necessary information is read, the read information is transferred together with the halftone dot image data, and a proof copy is created based on the information read by the color proof creation device 1 and the halftone dot image data. Produce proof copies with guaranteed conditions.

  As described above, according to the embodiments of FIGS. 6 to 8, the proof itself has the output condition information, so that a duplicate output under the same conditions can be created. Can be consistent.

  The coded image C in FIG. 7 includes, for example, a known bar code, and the reading units 70 and 126 detect the bar code, recognize the information content, and an information signal necessary for outputting the duplicate. Is output.

  Next, an example in which information necessary for outputting a duplicate is stored in an IC tag which is a non-contact tag and added to a proof will be described with reference to FIG. FIG. 9 is an electric circuit diagram of an IC tag attached to the proof and an IC tag reading unit provided in the color proof creating apparatus 1.

  As shown by a broken line in FIG. 7, the proof P has an IC tag 66 storing information necessary for output of a duplicate at a corner of the proof P and a part around the proof image G (non-image region). It is attached to. The IC tag 66 may be attached not only to the front surface of the proof P but also to the back surface.

  The information stored in the IC tag 66 is the image information / output conditions described above, but can be recorded in the IC tag 66 using a writing device. The recording timing may be when a corresponding proof is created or halftone image data is generated, but is not limited thereto.

  As shown in FIG. 9, the IC tag reading unit 70 ′ includes a coil unit 71, a power source 72, a modulation unit 70a for transmission, and a demodulation unit 70b for reception, and is indicated by a broken line in FIG. As described above, it is controlled by the control unit 50.

  The IC tag 66 is formed of a small IC chip, and includes a coil unit 67 made of a metal thin film, a modulation unit 66a for transmission, and a demodulation unit 66b for reception. The coil unit 71 of the reading unit 70 ′ and the coil unit 67 of the IC tag 66 communicate with each other by mutual induction and electromagnetic induction of the coil by an alternating magnetic field, and power is supplied.

  In FIG. 9, when transmitted from the IC tag reading unit 70 ′ via the coil unit 71, the IC tag 66 is received by the coil unit 67, and the electric power is stored therein as a power source, and the information signal stored in the IC chip. Is transmitted to the reading unit 70. The IC tag reading unit 70 ′ decodes the received information signal by the demodulating unit 70b, stores the read information in a built-in memory, and transfers it to the control unit 50 of FIG. The unit 50 obtains information necessary for outputting the duplicate based on the read information.

  As described above, the IC tag reading unit 70 ′ reads information necessary for the output of the duplicate in a non-contact manner by performing communication by radio waves from the IC tag 66. Further, since the IC tag 66 is received from the IC tag reading unit 70 'by the coil unit 67 and the electric power is used as the operating power, a driving power source is unnecessary and can be connected to the IC tag reading unit 70' without contact. In addition, since a terminal for contact with the outside is not required and the terminal can be configured only by the coil portion and the IC chip, cost reduction, weight reduction, and size reduction can be achieved. Of course, the image data generation apparatus 100 may include an IC tag reading unit similar to that shown in FIG.

  When the IC tag 66 of FIG. 9 is attached to the proof P of FIG. 7 and a proof copy is created by the color proof creation device 1, for example, in step S07 of FIG. 6, the color proof creation device 1 of FIG. The IC tag reading unit 70 'can read information necessary for the output of the duplicate from the IC tag 66 in a non-contact manner. Further, in step S12 in FIG. 8, the same IC tag reading unit provided in the image data generation apparatus 100 in FIG. 5 can read information necessary for outputting a duplicate without contact from the IC tag 66.

  As described above, the best mode for carrying out the present invention has been described. However, the present invention is not limited to these, and various modifications are possible within the scope of the technical idea of the present invention. For example, the information stored in the coded image C or the IC tag 66 of the proof shown in FIG. 7 may be only unique information, and information necessary for outputting a duplicate such as image information and output conditions corresponding to the unique information. May be recorded in the color proof creating apparatus 1 or the image data generating apparatus 100 so that it can be referred to when the unique information is read from the coded image C or the IC tag 66.

  Further, in FIG. 9, the IC tag is based on the electromagnetic coupling method using the electromagnetic coupling action that is tightly coupled. However, the present invention is not limited to this, and other types of IC tags and ID tags are used. For example, an electrostatic coupling method, an electromagnetic induction method, a microwave method, or the like can be used. The non-contact tag may be other than an IC tag, and for example, a magnetic tag can be used.

  Further, as indicated by a broken line in FIG. 1, PS data may be directly input from the client terminal 1 to the image data generation apparatus 100, and the PS data raster / image conversion process may be performed in the image data generation apparatus 100.

  The image data input to the image data generation apparatus 100 in FIG. 1 may be image data in various formats. For example, vector systems include PDF, EPS, etc. in addition to PS (PostScript) data. In addition, the raster system may be TIFF, TIFF / IT, and other dedicated formats, and the binary data may be TIFF bitmap, other dedicated formats, and the like.
