Description

  The present invention relates to an image forming apparatus, an image forming system, and a program capable of adding a second additional image to an image including a first additional image.

The image forming apparatus forms an image on a sheet based on the image data, and when cutting the sheet, prints a cutting mark such as a register mark as an additional image in a margin portion outside the image area of the sheet as a mark. There are cases.
In addition, the image forming apparatus can form an image on both sides of a sheet by providing a double-sided printing mechanism. The double-sided printing mechanism is usually a mechanism that reversely conveys a sheet body on one side of which an image is formed and conveys it to the upstream side in the conveying direction of the image forming unit. By the way, when performing double-sided printing, the paper may move along a conveyance path different from that in the case of normal single-sided printing, and image misalignment may occur between the front surface and the back surface. Further, on the front surface and the back surface, the size of the image may change due to the expansion and contraction of the paper due to the presence or absence of temperature rise or humidification. For this reason, an image forming apparatus has been proposed in which the front and back of the image can be adjusted by adjusting the positions of the front and back images and the magnification of the front and back.
In the front and back adjustment, an image position adjustment mark (for example, a register mark of a cross patch) is printed on the front and back of the paper, and an image is detected by an in-line detection unit to perform image formation adjustment.

In the printer controller of the image forming apparatus, when converting an image transmitted from the outside into an image for printing, an image combining process of combining the image data of the register mark with the image data is performed.
Japanese Unexamined Patent Application Publication No. 2006-242242 proposes a technique for printing a register mark without using a printer controller.

Therefore, when acquiring image information via the printer controller, the type of printer controller to be connected is limited.
On the other hand, the register marks may be used for different purposes such as a cutting mark or a front and back adjustment mark as described above, and an additional image may be printed to achieve each purpose. However, if the image information on which the register marks are formed is acquired through the printer controller and an attempt is made to form the register marks for other purposes, the registration marks may interfere with each other and the purpose of each register mark may not be achieved sufficiently.

The register mark information is provided only as data included in the image, and may be the register mark information (position information such as position and shape) included in the tag information and the image information.

  In this embodiment, the image forming apparatus 1 is described as including the printer controller 300. However, the image forming apparatus 1 does not include the printer controller, but includes the printer controller outside the image forming apparatus 1. Good.

The printer controller 300 performs RIP processing to generate an intermediate file as raster data. Image information is input from the printer controller to the input interface 140 (step s1, processing 1). The process numbers are indicated by circled numbers in FIG.
The image information is transferred from the input interface 140 to the memory control IC 130 (step s2, process 2). The memory control IC 130 temporarily stores the image information of the local memory 131 (step s3, processing 3).

Next, the image is transferred from the local memory 131 to the main body control CPU 110 via the memory control IC 130 (step s4, processing 4). The main body control CPU 110 transfers the image to the HDD 120 and temporarily stores it (step s5, processing 5).
Next, the main body control CPU 110 bit-maps the image data stored in the HDD 120 (step s6) and stores the bit-mapped image data in the system memory 111 (step s7, process 6). By storing in the system memory, address information for each pixel can be obtained.

The main body control CPU 110 performs parallel processing (steps s8 and s12).
In step s8, image data is transferred from the system memory 111 to the memory control IC 130 via the main body control CPU 110 in parallel with the registration mark analysis (step s8, process 7). The memory control IC 130 temporarily stores the image information in the local memory 131 (step s9, process 8).
The memory control IC 130 reads out the image information from the local memory 131 via the memory control IC 130 and transfers it to the image processing unit 210 (step s10, processing 9).
The image processing unit 210 performs image processing such as frequency conversion, color adjustment, density adjustment, and screen processing on the image data, and transfers the image data to the image combining unit 230 (step s11, processing 10).

On the other hand, in step s12, the main body control CPU 110 reads the image data stored in the system memory 111, analyzes the image data to acquire the arrangement information, and transfers the result to the register mark determination unit (process 7A).
The analysis can be performed by obtaining the address information and the image presence information for each pixel in the memory storage and analyzing the register mark shape / position together with the paper size information.
The analysis may be performed by evaluating the image data itself, or may be performed by using the tag information regarding the register mark. In the analysis, the arrangement information such as the position, shape, line thickness, intersection angle of a plurality of lines of the registration mark is obtained. The analysis process can be executed by a program executed by the main body control CPU 110.

  The registration mark determination unit performs determination processing (processing 8A, steps s13 to s16). The determination process is executed by a program executed by the main body control CPU 110. The main body control CPU 110 knows the layout information of the correction register marks, and uses the layout information of the correction register marks in this determination process.

In the determination process, first, based on the arrangement information of both the registration marks, it is determined whether the registration marks as the first additional image can substitute the registration marks for correction as the second additional image (step s13). In the determination, a reference can be set based on the purpose of use of the register mark that is the second additional image (the purpose of correcting the image forming apparatus). In this embodiment, since the register mark of the second additional image is used for confirming the point and adjusting the magnification on the front and back sides, it is necessary to confirm the coordinate for confirming the point. The registration mark determination unit determines whether or not the registration mark, which is the first additional image, can be substituted based on the position, shape, line thickness, intersection angle of a plurality of lines, and the like.
Further, in the determination, a determination criterion of whether or not it can be used is set in advance. For example,
-Consider the allowable range when the position is different from the registration mark, the allowable length of the line, the allowable thickness range, and the angle when multiple lines intersect.

As a result of the substitution determination, when it is determined that the substitution can be performed (Yes in step s14), the registration mark forming unit 220 is instructed not to form the correction registration mark (step s15, process 9A).
On the other hand, as a result of the substitution determination, when it is determined that the substitution cannot be performed (No in step s14), it is determined whether the registration mark (cutting mark) in the image data and the correction registration mark do not overlap based on the comparison of the arrangement information of both the registration marks. The determination is made (step s16).

When the registration marks (cutting marks) in the image data and the correction registration marks do not overlap (Yes in step s16), the registration mark forming unit 220 is instructed to form the correction registration marks (step s17, processing 9A), and the registration mark forming unit 220 is instructed. A registration mark for correction is formed (step s19, processing 9A).
On the other hand, when the registration marks in the image data (cutting marks) and the correction registration marks overlap (No in step s16), the registration mark forming unit 220 is instructed to adjust the position of the correction registration marks and form the registration marks (step s18,). Treatment 9A).

The register mark forming unit 220 includes a register mark information storage RAM, a register mark formation position setting register, position adjustment, and a register mark formation circuit.

The register can store the image data address of the registration mark for correction, the address of the corrected image data, and the like. In the position adjustment, processing is performed so as to form a cutting register mark at the designated position. In that case, the register marks for correction whose position is corrected by using the image data of RAM or the register are stored in the RAM, and the address of the register is registered.
After instructing the register mark formation in step s17 or step s18, the register mark forming unit forms a correction register mark (step s19, process 9A), and transfers the register mark image to the image combining unit 230 (process 10A).

After step s15 or step s19, the image synthesizing unit 230 synthesizes the correction register mark with the image data in the image area as needed, and transfers the image data to the image quality adjusting unit 240 (step s20, process 11).
The image adjustment unit 240 adjusts the image writing position and the front and back magnification, and transfers the image to the print unit 250 (step s21, process 12).
The printing unit 250 prints out on paper and outputs the printed paper to the reading device 20 (step s22, processing 22). At this time, if the arrangement information of the registration mark for correction (arrangement position in this embodiment) is changed, the fact is notified to the reading device 20.
In the inspection unit included in the reading device 20, if the arrangement of the correction register marks has been changed, the image reading unit 24 reads the image of the correction register marks and reads the image on the printed sheet. The image is read and inspected, the inspection information is output to the printer engine (step s23, process 13), and the process ends.
The printer engine can calculate the front-to-back magnification based on the inspection result and feed it back to the image adjusting unit 240. The parameters adjusted by the image adjusting unit 240 are updated based on the feedback information.

  When the user forms the cutting marks, and when the correction of the image forming apparatus is performed while forming the image, the correction marks are formed in the cutting area. If there is no cutting area, the registration mark for correction is not formed. Further, when the image forming apparatus is not corrected during image formation, the correction register mark is not formed. Although the registration marks for correction are formed in order to adjust the position and the magnification of the front and back while forming an image, this is not necessary in the mode in which the above adjustment is not performed.

  In the embodiment of FIG. 2, the main body control unit 100 has been described as analyzing the additional image, but the additional image may be analyzed when the image information is input.

Image information is input to the print controller 300 from the outside such as the external device 2.
The printer controller 300 performs RIP processing to generate an intermediate file as raster data. Image information is input from the printer controller to the input interface 150 (step s30, process 20). The process numbers are indicated by circled numbers in FIG.

In the input interface 150, the image data is bitmap converted by the built-in bitmap conversion function and stored in the internal memory 151 (step s31, process 21).
Next, the input interface 150 performs parallel processing (steps s32 and s36).

In step s32, the image information is transferred from the internal memory 151 to the memory control IC 130 (process 22).
The memory control IC 130 temporarily stores the image information of the local memory 131 (step s33, process 23).
The image is transferred from the local memory 131 to the image processing unit 210 via the memory control IC 130 (step s34, processing 24).
The image processing unit 210 performs image processing such as frequency conversion, color adjustment, density adjustment, and screen processing on the image, and transfers the image to the image combining unit 230 (step s35, processing 25).

On the other hand, in the input unit, the image data input to the image forming apparatus 1A from the printer controller 300 is received by the input interface 150. It is converted into bitmap data by the bitmap conversion function installed in the input interface 150 and stored in the internal memory 151 of the input interface 150. By storing in the memory, the address information for each pixel can be obtained. With respect to the image data stored in the internal memory, the register mark analysis unit mounted inside the input interface 150 analyzes the register mark information in the image data, and transfers the analysis result to the register mark determination unit 152 (step s36, process 22A). The registration mark determination unit 152 compares the registration mark information in the image data with the correction registration mark, and determines whether the registration mark in the image data can be substituted as the correction registration mark (step s37, process 23A).
In the register mark determination process, since the register mark of the second additional image is used for image position adjustment, it is determined whether or not it is possible to confirm the coordinates by fixing the point with the cutting register mark. The registration mark determination unit 152 determines whether or not the registration mark, which is the first additional image, can be substituted from the registration mark position, shape, line thickness, intersection angle of a plurality of lines, and the like.
Further, in the determination, a determination criterion of whether or not it can be used is set in advance. For example,
-Consider the allowable range when the position is different from the registration mark, the allowable length of the line, the allowable thickness range, and the angle when multiple lines intersect.

  In the case where the input unit has the bitmap data conversion function, the register mark analysis function, and the register mark determination function, it is not necessary to perform the processing via the main body control CPU, so that the load on the CPU can be reduced.

As a result of the substitution determination, when it is determined that substitution can be performed (Yes in step s38), the registration mark forming unit 220 is instructed not to form the correction registration mark (step s39, process 24A).
On the other hand, as a result of the substitution determination, when it is determined that the substitution is not possible (No in step s38), it is determined whether the registration marks in the image data (cutting marks) and the correction marks do not overlap by comparing the arrangement information of both the registration marks. (Step s40).

The register mark forming unit 220 has a RAM or register, position adjustment, or register mark forming configuration or function. The RAM can store the image data of the registration mark for correction. The register can store the image data address of the registration mark for correction, the address of the corrected image data, and the like. In the position adjustment, the position of the correction register mark is changed so as not to overlap the cutting register mark based on the position, shape, etc. of the cutting register mark.
After the registration marks are formed by the registration mark forming unit 220, the registration marks are transferred to the image combining unit 230 (process 25A).

After step s35 or step s43, the image synthesizing unit 230 synthesizes the image data in the image area with the registration marks for correction as needed, and transfers the image data to the image quality adjusting unit 240 (step s44, process 26).
The image adjustment unit 240 adjusts the image writing position and front and back magnification, and transfers the image to the print unit 250 (step s45, process 27).
The printing unit 250 prints out on paper and outputs the printed paper to the inspection unit included in the reading device 20 (step s46, process 28).
At this time, if the arrangement information of the registration mark for correction (arrangement position in this embodiment) is changed, the fact is notified to the reading device 20.
In the inspection unit included in the reading device 20, if the arrangement of the correction register marks has been changed, the image reading unit 24 reads the image of the correction register marks and reads the image on the printed sheet. The image is read and inspected, the inspection information is output to the printer engine (step s47, process 29), and the process ends.
The printer engine can calculate the front-to-back magnification based on the inspection result and feed it back to the image adjusting unit 240. The parameters adjusted by the image adjusting unit 240 are updated based on the feedback information.

Similar to the above-described embodiment, when the user forms the cutting marks and the correction of the image forming apparatus is performed while forming the image, the correction marks are formed in the cutting area. When there is no cutting area, the registration mark for correction is not formed.
Further, when the image forming apparatus is not corrected during image formation, the correction register mark is not formed. Although the registration marks for correction are formed in order to adjust the position and the magnification of the front and back while forming an image, this is not necessary in the mode in which the above adjustment is not performed.

Whether or not the additional images can be substituted and the overlap of the additional images will be described with reference to FIGS.
In the upper right diagram of FIG. 8, the trimming marks T1 indicating the cutting positions are formed in the four margins of the cutting margin, which are formed in the margin P1 around the image area P0 of the paper P and including the cutting margin. Show. The information about this image is included in the image information input to the input unit.
The trimming marks are included in the controller input image (with the register marks).
The registration mark position and shape depend on the controller and user. Registration marks are formed in a cutting area (outside the image area) that is unnecessary in cutting.

In the upper left diagram of FIG. 8, correction register marks T2 for magnification adjustment are formed at the four corners of the margin P1 of the paper P.
The lower part of FIG. 8 shows a state in which the trimming marks are output on the sheet as the correction marks.
The image of the cutting mark T1 indicates that the specific position can be read and determined, and can be used as a correction mark.
The registration mark for correction is used in a mode for correction during image formation, and corresponds to execution of correction during image formation by forming registration marks outside an image area that is unnecessary by cutting.

In the upper left diagram of FIG. The correction register marks T20 for adjusting the image position are formed at the four corners.
The lower part of FIG. 9 shows a state in which the trimming marks T10 and the correction mark T20 are printed on the paper, respectively. The trimming mark T10 is difficult to detect a specific position by reading an image, and cannot be used as a correction mark for position adjustment. Further, when the trimming mark T10 and the correction mark T20 are printed on the paper, they do not overlap with each other, and the respective marks can achieve the purpose.

In the upper right diagram of FIG. 10, a trimming mark T11 indicating the cutting positions is formed at the four corners that are the boundaries of the cutting margin in the margin P1 including the cutting margin. In the upper left diagram of FIG. The correction register marks T21 for adjusting the image position are formed at the four corners.
In this embodiment, the trimming marks T10 cannot be used as the correction marks, and it is determined that the marks will overlap each other when printed on the paper.
The lower part of FIG. 10 shows a state in which the correction register mark T11 is directly formed on the sheet and overlaps with the cutting register mark T21. In this embodiment, in this case, the correction register mark T21 is formed as the correction register mark T22 by shifting to a position where it does not overlap the cutting register mark T11. As a result, the purpose can be achieved for both the cutting mark T11 and the correction mark T22.
In this example, the register mark positions are adjusted based on the analyzed register mark information so that the positions of the correction register marks do not overlap. It is desirable to adjust the position in the sub-scanning direction, but only the position adjustment in the main scanning direction may be performed.

In the above embodiment, when it is necessary to change the arrangement information of the second additional image, the arrangement position is changed so that the second additional image does not overlap the first additional image. However, the change of the arrangement information is not limited to this in the present invention, and it is sufficient that the first additional image and the second additional image can be distinguished when the additional image is read. .
For example, by changing the color of the second additional image, it is possible to easily distinguish it from the first additional image. In particular, by changing the color of the second additional image so as to be different from the color of the first additional image, the identification becomes easy. At this time, the cutting marks and the correction marks may not be in the same position.
In addition, by changing the shape of the second additional image, it is possible to easily distinguish it from the first additional image. Particularly, when the shape of the first additional image and the shape of the second additional image are the same, the shape of the second additional image is changed so that the shape of the second additional image is different from the shape of the first additional image. The change facilitates identification. Note that both the color and the shape may be changed. The positions of the trimming marks and the correction marks may not overlap.

  According to this embodiment, it is possible to correct the image forming apparatus in parallel with image formation without affecting the register marks generated by the printer controller. When there is a register mark that can be substituted by an input from the printer controller, it is not necessary to form an extra register mark, and it is possible to suppress the formation of a register mark that is not a user's intention even though it is a blank space.

  Further, in this embodiment, since the register mark position and shape can be analyzed with respect to the printer controller input image data on which the register marks are formed, it is possible to correspond to any printer controller regardless of the printer controller type. Becomes

  Further, in this embodiment, the program of the present invention is described as being provided in the image forming apparatus, but the program of the present invention is executed by executing the program of the present invention by a management device that manages the image forming device or a control unit of a remote device. The operation may be performed.
