Further, as described above, even inside the registration marks M1 to M8, the margin area can be appropriately set according to the content and use of the output target image F. Further, as shown in FIG. 6A, when a plurality of images are combined as output target images, the relative positional relationship of these plurality of images can be finely adjusted. Here, the position of the lower left image is fine-tuned.
In relation to post-processing such as cutting of the recording medium, normally, a plurality of output patterns for forming a single output target image F at different positions of the recording medium are not set, but such a plurality of outputs The pattern may be set.

Further, if the output target image, its arrangement, and the margin area are not set, the subsequent output pattern setting operation cannot be performed. Therefore, until the output target image and the margin area are set, the output pattern setting selection, etc. are performed. It is possible to control not to accept the selection operation of.

FIG. 6B shows a display example when the condition setting screen is open.
Here, a plurality of output patterns set in the output pattern setting selection are displayed in a list from "normal output" to "output 1 at the time of discharge abnormality detection", and among them, the fixed interval output 2A is selected.

The output condition setting of the output pattern "fixed interval output 2A" is displayed at the upper part of the right screen. Here, when the fraction of the number of output times is "2" once in 1000 images, this "fixed interval output" is displayed. An image of the output pattern named "2A" is recorded.
When these output conditions are duplicated, an image having a high priority is output based on the reference priority and the user-set priority. If the priority is set by the user, the images of the output pattern having the higher priority are given priority and output in order. If the priorities set by the user are the same or not set by the user (displayed as "normal" here), the output is performed according to the reference priority. As the reference priority, for example, in descending order of priority, an output pattern output on condition of abnormality detection, an output pattern output at regular intervals, and an output pattern normally output are determined in this order.

FIG. 7A shows an example when the test image selection menu is open. The test images that can be selected are registered in the test image storage unit 403b in advance, and here, a discharge defect detection image that detects density unevenness due to ejection defects by a halftone image or the like, and an individual discharge defect detection image at a predetermined position from each nozzle. In order to correct the density unevenness and color tone deviation that occur depending on the ejection failure nozzle identification image for identifying the nozzle that ejects ink to the ink and the ejection failure, the drive voltage difference between the heads, the operating status of the drive element, etc. The density unevenness detection image and the color patch (color management image) of the above are mentioned. Further, here, the ejection area related to the ejection of ink can also be selected as the adjustment ejection range.
For one output target image data, a test that has not been set by the user is performed by making the display color different between the test image that has never been selected in all the output patterns and the test image that has already been selected at least once. It may be possible to make the image easier to recognize. Further, a test image of a type that does not need to be recorded for the output target image, for example, an ejection failure detection image of a nozzle that ejects a type of ink that is not used in the output target image, is determined by the control unit 40 or is determined by the user. It may be possible to switch the display form or temporarily delete it from the selection menu by the input operation of.

FIG. 7B shows an example when the operation menu of the test image is opened. The operation contents include division of one image into a plurality of blocks, combination of a plurality of images (blocks), enlargement / reduction, transformation, movement and rotation, and the like. Further, it may be possible to perform trimming without deformation or reduction. Although the selection switches are displayed here, it is assumed that these operations are performed by various drag operations using the user's finger or a touch pen, and the selection switches should not be displayed. May be.

8, 9 and 10 are diagrams showing an example of a test image editing operation.
As shown in FIG. 8A, the test image TC0 used as the color patch (color management image) arranged in the left margin is larger than the margin range, and here, the outer frame is shown by a broken line. It is warned as a test image that cannot be placed as it is. Alternatively, the outer frame may be further colored with a predetermined color, or not only the outer frame but also the inside may be colored with a net wire or the like. Further, only the portion of the inside that overlaps with the output target image or the finishing range may be colored. Further, with the current size and orientation, the color to be colored may be different depending on whether the existing margin cannot be entered or if it can be entered by simply moving it.
For this test image TC0, here, division is selected as an editing operation, and the positions indicated by the horizontal solid line and the arrow E1 are shown as cutting position candidates. By performing the execution operation here, the test image TC0 in which a plurality of color patches are combined is divided, but the cutting position is the range in which the cutting is possible for the test image that can be cut. Can be adjusted as appropriate.

As shown in FIG. 8B, the test images TCp1 and TCp2 in which the image for the color patch is divided into two are still arranged so as to protrude from the margin area, and are warned by the broken line display. Here, reduction is selected as the editing operation, and the reduction operation is possible by the markers at the four corners of the test image TCp1 to be selected and the arrow E2. Alternatively, the reduction may be performed by inputting a numerical value of the reduction ratio in the temporarily generated window W1 or performing an operation of changing the numerical value.

At this time, the test image may be arranged inside the outer ends of the registration marks M1 to M8, or may partially overlap with the registration marks M1 to M8. A warning may be displayed for these situations, but the final placement decision may not be prohibited.

Further, as shown in FIG. 9A, when it is troublesome to manually perform all the arrangements, the initial arrangements can be automatically performed (initial settings are performed). After selecting the test image (here, test image TA0, TB0, TC0, TD0, TEc0, TEm0, TEy0, TEk0) that you want to place in the test image selection menu, you can execute automatic placement in the test image placement operation menu. , The control unit 40 (CPU401) searches for a possible arrangement pattern and executes it. Alternatively, a standard test image combination may be automatically obtained and displayed without the user selecting a test image. The algorithm related to the arrangement in this case is appropriately set, but it does not necessarily have to have a high ability to derive a complicated optimum arrangement in a short time.

Also, at this time, instead of automatically arranging all the test images, after setting the arrangement of some test images and performing the operation of fixing the arrangement of the test images, the remaining unfixed test images May be performed automatically.

The determined arrangement pattern of the test image can be stored in the history storage unit 403d as history data. The CPU 401 can learn each test image and the appearance frequency of the arrangement pattern between a plurality of test images by a predetermined algorithm based on the history data, and can reflect the appearance frequency of the arrangement pattern among the plurality of test images at the time of subsequent execution of the initial arrangement. ..

In addition, the warning content may be displayed in a pop-up by hovering the cursor over the abnormal part so that the user can easily recognize when the number of warnings is large or the warning is complicated. Alternatively, as shown in FIG. 9B, a warning display screen W2 may be provided below the preview screen to display the warning content in characters. This warning may include a notification to that effect when the normally set test image is not included in the setting.

Further, a part of the test image set in the output pattern of the fixed interval output 2A shown in FIG. 10A is transferred to another output pattern, here, the fixed interval output 2B shown in FIG. 10B (). Can be placed separately). Here, for example, the test image TCp2 is selected as the migration target, and the output pattern of the migration destination is selected in the temporarily displayed window W3 to be the fixed interval output 2B. As shown in FIG. 10B, the arrangement of the test images TF, TG, etc. including the test image TCp2 is determined on the screen of the test image arrangement operation related to the output pattern of the fixed interval output 2B to which the test image TCp2 is transferred. Has been done.

FIG. 11 is a flowchart showing a control procedure by the control unit 40 of the image output process executed by the inkjet recording apparatus 1 of the present embodiment.
Here, a case where the user is activated without specifying the output target image based on the input operation to the display operation unit 50 (operation reception unit 501) will be described.

When the image output process is started, first, the control unit 40 (CPU401) sets the output target image based on the received input operation, arranges the output target image, and initially sets the margin area (step). S101). The control unit 40 changes the arrangement of the output target image and the setting of the margin area based on the received input operation (step S102).

The control unit 40 performs an edit setting operation of the output pattern including the test image based on the received input operation (step S103; recording arrangement pattern setting step). The control unit 40 determines whether or not the readjustment request for the margin setting has been input (step S104), and if it is determined that the request for readjustment of the margin setting has been input (“YES” in step S104), returns the process to step S102.

If it is determined that no input has been made (“NO” in step S104), the control unit 40 determines whether or not the end of the output pattern edit setting operation has been normally completed by the user's confirmation operation (“NO”). Step S105). It did not end normally, that is, the output pattern was not set at all, the image output with no output pattern set was included, or the test image that could not be placed in the output pattern was included. In such cases (“NO” in step S105), the control unit 40 saves (stores) the settings in the output pattern storage unit 403c (step S116), and ends the image output process. In the output pattern setting data stored in the output pattern storage unit 403c, the image data of each set test image may already be embedded, or is simply associated with an actual test image such as an identification number. The information may only be stored in association with the arrangement coordinates and the edited contents.

When it is determined that the edit setting operation of the output pattern is normally completed (“YES” in step S105), the control unit 40 determines whether or not the image recording start request has been input (step S106). .. If it is determined that no input has been made (“NO” in step S106), the process of the control unit 40 shifts to step S116. If it is determined that the input has been made (“YES” in step S105), the control unit 40 causes the head unit 23 to start the image recording operation (step S107; discharge control step).

The control unit 40 determines whether or not an abnormality that needs to be dealt with is detected during image recording (step S108). If it is determined that no abnormality has been detected (“NO” in step S108), the process of the control unit 40 shifts to step S111. If it is determined that an abnormality has been detected (“YES” in step S108), the control unit 40 determines whether or not the abnormality can be automatically corrected (step S109). When it is determined that automatic correction is possible (“YES” in step S109) to the extent that no problem occurs in the recorded image of the output target image (“YES” in step S109), the control unit 40 corrects the image. This is done automatically (step S110). Then, the process of the control unit 40 shifts to step S111, and determines whether or not all the number of images have been recorded (step S111). If it is determined that the recording of all the images has not been completed (“NO” in step S111), the process of the control unit 40 returns to step S108.

When it is determined that the recording of all the images has been completed, the control unit 40 ends the image output process.

If it is determined in the determination process of step S108 that the detected abnormality cannot be automatically corrected (“NO” in step S108), the control unit 40 performs a predetermined notification operation indicating the occurrence of the abnormality. The notification output unit 47 is made to perform the image recording operation, and the image recording operation is stopped (step S119). Then, the control unit 40 ends the image output process.

As the content of the automatic correction executed in the process of step S110 described above, various well-known ones related to the correction of the output target image, the correction of the driving operation, and the like can be selected. For example, when a nozzle ejection failure is detected, the output target image is adjusted so that the ink ejection from the ejection failure nozzle is stopped and the ink ejection operation is performed from the nozzles arranged on both sides in the width direction. Can be done. Further, when the image density is different between the plurality of recording heads, the drive voltage and the drive waveform can be adjusted so as to increase or decrease the ink ejection amount in the predetermined recording head.

As described above, the inkjet recording device 1 of the present embodiment includes a recording head (head unit 23) provided with a nozzle for ejecting ink to the recording medium P, and an operation reception unit 501 for receiving a user's input operation. , The control unit 40 is provided. As a recording arrangement pattern setting means, the control unit 40 ejects ink with respect to the output range of the output target image to be recorded on the recording medium P by the ink ejection operation from the nozzle based on the operation content accepted by the operation reception unit 501. An output pattern setting is performed in which an ink adjustment ejection range corresponding to at least one of a plurality of types of adjustment inspections related to operation is arranged with respect to the recording medium P, and the ejection control means is described as described above according to the arrangement pattern setting. Ink ejection operation is performed. At this time, the control unit 40 as the recording arrangement pattern setting means divides at least a part of the adjustment discharge range corresponding to the plurality of types of adjustment inspections into a plurality of blocks according to the operation received by the operation reception unit 501. Can be placed.
In this way, when adjusting ejection such as a test image or ink ejection is output together with a normal output target image, the adjustment ejection range for each purpose can be further separated into a plurality of places by setting the operation by the user. By making it possible to arrange it, it is possible to efficiently output a test image and make adjustments while reducing unnecessary gaps. In particular, since the user manually adjusts, it is easy and efficient to arrange the adjustment discharge range while considering the presence or absence of placement inside the finish range set by the register mark, which is difficult to judge automatically, and the places where it can be placed. Can be done. In addition, even if it is a test image that is originally preferable to be output in a batch, it may be better to separate it rather than not being able to output it. Since there is a problem that the algorithm becomes complicated and the cost rises more than necessary, it is possible to make appropriate settings with appropriate user judgment.

Further, an image reading unit 25 for reading the surface of the recording medium P is provided, and the control unit 40, as a detection means, reads data (read data by the image reading unit 25 of the inspection image recorded within the adjustment discharge range according to the output pattern setting). That is, a defect related to the ink ejection operation is detected from the image data obtained by the imaging unit 255), and as a correction means, among the image data of the image to be output and the ink ejection operation from the nozzle based on the detection result by the imaging unit 255. After at least one correction is performed and the correction (that is, correction of the output target image, adjustment of the drive waveform and voltage during the ink discharge operation) is performed as the discharge control means, the ink discharge operation is performed according to the output pattern setting. To do. In this way, since the inkjet recording device 1 is provided with an in-line sensor (imaging unit 255) and can immediately image the output test image to determine a defect, it is easy to output the image to the recording medium P. Moreover, it is possible to promptly deal with the defect and reduce the waste of the recording medium P. Further, while outputting the image to be output, correction can be performed at any time to continue the output of an appropriate image, so that the output of the image is not interrupted more than necessary, and on the other hand, the output of the recording medium is wasted. It is possible to output the required output target image at high speed and appropriately.

Further, the control unit 40 as the ejection control means determines whether or not the recorded image of the output target image due to the ink ejection operation is expected to satisfy a predetermined image quality reference level by correction, and if it is not expected to satisfy the head. The ink ejection operation by the unit 23 is stopped. That is, if the image quality of the output target image does not reach the required level in the above correction operation in real time, the user, administrator, or maintenance person needs to take measures such as replacing the head unit 23, so promptly. Image recording can be stopped to eliminate waste. In addition, since necessary test images are recorded and defects are detected at an appropriate frequency and timing by manual placement, the time from when such a problem occurs until the image recording operation is stopped is detected. The user can decide as appropriate to be appropriate.

Further, the control unit 40 as the recording arrangement pattern setting means can set the output range of the output target image F. Therefore, when the adjustment ejection range of the test image does not fit in the margin slightly, the test image can be arranged more efficiently and appropriately by moving the output target image F, and the ink ejection state is related with appropriate accuracy. Inspection can be performed.

Further, when the output target image F is a combination of a plurality of images, the control unit 40 as the recording arrangement pattern setting means can set the relative arrangement of the plurality of images. Normally, the plurality of images are arranged so as to be optimal in number and arrangement interval, but by enabling fine adjustment in consideration of the output pattern of the test image, a wasteful recording medium is generated when an abnormality occurs. It is possible to more easily obtain a preferable output pattern setting that can suppress the above.

Further, the control unit 40 as the recording arrangement pattern setting means can set a plurality of types of output patterns related to the arrangement of the adjustment discharge range for one output target image, and is operated by the operation reception unit 501. Selection conditions for setting a plurality of types of output patterns are determined based on the contents, and the control unit 40 as a discharge control means responds to the selection conditions for each recording of the output target image when the output target image is recorded a plurality of times. Select one output pattern setting to perform the ink ejection operation according to the one output pattern setting.
Normally, it is not possible to fit many test images and ink ejection areas in one margin area, so if only the required frequency is set, a sufficient adjustment ejection range or a specific defect is detected. For example, in order to record a more detailed test image only in the image, an output pattern to be recorded according to the selection condition can be defined separately from the normal output pattern together with those selection conditions. Therefore, it is not necessary to require a space on the recording medium or an ink ejection amount to determine the adjustment ejection range more efficiently than necessary, and various adjustment operations and defects can be detected more efficiently.

Further, the control unit 40 as a recording arrangement pattern setting means can disperse and arrange a plurality of divided blocks in a plurality of types of output pattern settings. That is, it is possible to divide an adjustment discharge range that requires a large output range of a test image or an adjustment discharge range that does not fit in one margin area due to arrangement with other test images, and further divide the adjustment discharge range into different output pattern settings. You can. For example, if the frequency of obtaining the entire output of one test image is low, the test images that are frequently required are preferentially placed, and then divided into the gaps remaining in each output pattern and partly divided. Since it is sufficient to output a block of the test image, the test image can be arranged by effectively utilizing such a gap.

In addition, among the inspection images recorded within the adjustment discharge range according to the adjustment inspection, those that can be divided into a plurality of blocks include a defective nozzle identification image, a density unevenness detection image, and a color patch (color management image). included. That is, test images that do not fit in one of these margins, and those that do not need to be output at once and can be processed collectively after all the output is done as long as the read data is retained, are appropriate. By dividing, the output of the output target image is not interrupted, and the output of other necessary test images is not hindered.

Further, the control unit 40 as the recording arrangement pattern setting means can perform at least one of reduction, deformation, and rotation on the plurality of divided blocks. The test image is usually formed in the required size, but depending on the situation, it may be slightly smaller or deformed without problems, so make sure that it fits properly according to the margin area. It is also possible to deform and arrange it, and by performing a difficult division arrangement even with such automatic arrangement, it is possible to more efficiently test defects and make adjustments related to ink ejection.

Further, a display unit 502 for displaying the output pattern of the set output target image and the output pattern of the adjustment discharge range is provided, and the control unit 40 as the recording arrangement pattern setting means has the adjustment discharge range displayed on the display unit 502. The operation receiving unit 501 accepts the operation of modifying the arrangement of the above, and sets the output pattern according to the modified display.
In this way, the output target image F and the adjusted discharge range can be set interactively via the display screen, so that the user can easily and appropriately set these arrangements while observing the remaining condition of the margin area. Can be done.

Further, the control unit 40 operates as an initial setting means for setting the initial arrangement of the adjustment discharge range, and the control unit 40 as the recording arrangement pattern setting means sets an output pattern according to the initial arrangement displayed on the display unit 502. The operation receiving unit 501 accepts the operation of approving or modifying the above, and sets the output pattern. In this way, it takes a lot of time and effort to manually set the test image and the ink ejection area, etc., so it takes time and effort for the user to perform the necessary range adjustment operation after making the initial settings as appropriate. Efficient and effective output setting can be performed while reducing the amount. Further, for such an initial setting, the amount of correction by the user can be appropriately reduced by using a conventional learning algorithm or setting a test image to be preferentially arranged in advance. ..

Further, the control unit 40 as the ejection control means starts the ink ejection operation according to the output pattern setting after the operation receiving unit 501 receives the confirmation operation of the output pattern setting. In this way, by starting the image recording after the approval of the output pattern is obtained by the user, it is possible to surely perform preferable output and prevent the user from forgetting to set the setting.

Further, in the inkjet recording apparatus 1, by using an image recording method in which an image recording method is used in which the arrangement range of the output target image and the adjustment discharge range are arranged via the input operation to the operation reception unit 501 as described above to output the image. It is possible to efficiently output a test image and make adjustments related to ink ejection while reducing unnecessary gaps in the margin area. In particular, since the user manually adjusts, it is easy and efficient to arrange the adjustment discharge range while considering the presence or absence of placement inside the finish range set by the register mark, which is difficult to judge automatically, and the places where it can be placed. Can be done.

The present invention is not limited to the above embodiment, and various modifications can be made.
For example, in the above embodiment, a conditional branch is provided to output a test image corresponding to the abnormality in the margin area when an abnormality is detected. However, this condition setting may be further extended to a plurality of stages, and the condition is YES. Not only / NO but also different branches may be set according to the abnormality detection level. Further, depending on the clarity and seriousness of the abnormality, a setting may be included in which the output of the output target image is stopped and the test image is formed on the entire recording medium instead of forming the test image only in the margin area.

Further, in the above embodiment, the original test image is simply divided, but if it becomes difficult to detect an abnormality in the boundary portion cut by the division, the division may be performed with some overlap. The size of the test image as a whole may be slightly increased if it is easy to arrange by dividing into a plurality of small size blocks.

Further, in the above embodiment, the user can set the image via the GUI, but it is as simple as using a table showing the output range of the output target image and each adjustment discharge range numerically (coordinates). It may be set via the UI.

Further, in the above-described embodiment, it is possible to perform operations such as deformation, reduction, and trimming of the test image, but these operations may not be possible. Further, even if deformation, reduction, and trimming are possible, operation control can be performed so that the operation can be performed only within the limited range.

Further, in the above embodiment, the selection conditions for each output pattern are set individually, but the plurality of output patterns are related so that the selection conditions for the plurality of related output patterns are appropriately arranged and determined. By setting, the initial setting or the setting may be restricted so that the selection condition corresponding to one selection condition is reflected in another output pattern.

Further, in the above embodiment, it has been described that the analysis of the test image and the detection of defects are performed by the operations of the image reading unit 25 and the control unit 40. , Correction or interruption of ink ejection operation may be performed.

Further, in the above-described embodiment, the inkjet recording apparatus 1 having a single-pass line head has been described as an example, but the present invention is not limited thereto. The present invention can be similarly applied to a multi-pass type or a scan type in which the inkjet head is moved with respect to the recording medium.
In addition, specific details such as the configuration, the display and operation method, the type and use of the test image to be output, the processing content and the processing procedure shown in the above-described embodiment are appropriately provided without departing from the spirit of the present invention. It can be changed.
