DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for managing a processing step of a wound material, and more particularly to a management apparatus for managing a processing step of a wound material using a computer.

[0002]

2. Description of the Related Art A method of producing a product by processing a winding material is suitable for mass production of the product, and is currently used in various fields. For example, the process of manufacturing a packaging bag is also employed in the process of manufacturing a food packaging bag. That is, a printing process is applied to a plain take-up material called a printing material, and a laminating process is performed to attach another take-up material thereto.
A packaging bag is manufactured. As described above, usually, a plurality of processing steps are sequentially performed on the wound material.

[0003]

Generally, when various processes are performed on a winding material, good processing is not always performed on all portions. Usually, processing defects occur partially. For example, in the case of a printing process, defective printing occurs, and in the laminating process, a defective portion in which the sheet is wrinkled occurs. The rolled material that has undergone various processes is finally cut off for each product, but at this time, it is necessary to exclude products having defects.
For this reason, for each process, an operation is performed to check which part has a certain processing defect. That is, in the past, a monitor was set up for each process to monitor whether processed materials had processing defects.
If a processing defect has occurred, the operator writes that fact on the quality control card and inserts a tape indicating the occurrence of the processing defect into the wound material. This quality control card is sent to the next processing step together with the processed winding material. In this way, for each process, what kind of processing defect has occurred in which part is entered in the quality control card. Defective products can be finally excluded based on the information on processing defects entered in the quality control card.

[0004] However, there is a problem that errors are apt to occur in the above-described work of filling in the quality control card. If there is such an error, the defective product cannot be finally removed, and the defective product is shipped as it is. In addition, the work of filling in the quality control card depends on the manual work of the observer, and there is a problem that the work load is large.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for controlling a process of processing a rolled material, which does not cause an error and can reduce a burden on an operator.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. As described above, the present invention relates to Japanese Patent Application No. Hei 2-3014.
This is a further improvement on the winding process control apparatus disclosed in the specification of JP-A No. 24. So for convenience,
First, a basic device disclosed in the above specification will be described, and then, an improved portion which is the gist of the present invention will be described.

Here, an embodiment in which the present invention is applied to a process of manufacturing a food packaging bag will be described. FIG. 1 is a diagram showing a process of manufacturing a general food packaging bag which is currently performed.
First, a winding material 1 called a printing material is prepared, and is subjected to printing through a printing process. The winding material 2 that has completed the printing step is attached to another winding material (not shown) in the synthesis step, and is subjected to a laminating process. Further, the laminated winding material 3 is cut into two winding materials 4a and 4b in a cutting step (usually, it is cut into more winding materials, but here, for convenience of explanation, It shows the case of cutting into two). An inspection process is performed on the cut rolled materials 4a and 4b, and a packaging bag 5 is manufactured through a bag making process.

In each of the above steps, the winding material is set on one of the paper feeding sides, the leading end of the material is led out to the other paper discharging side, and the winding material is moved from the paper feeding side to the paper discharging side. The predetermined processing operation is performed while sending the same. For example, in the case of a printing process, the rollers of the printing press are placed between the paper feed side and the paper discharge side. The take-up material pulled out from the paper supply side is printed and then wound up to the paper discharge side. Note that the process order shown in FIG. 1 shows an example as a simple model, and in practice, a more complicated procedure is adopted, such as changing the order of each process or returning to the previous process. Often. Here, as a simple model, three printing machines are used in the printing process, two combining devices are used in the combining process, two cutting devices are used in the cutting process, and two inspection devices are used in the inspection process. In the process, the description will be continued below on an example in which three bag making machines are used.

FIG. 2 is a block diagram showing a configuration of a winding material processing step management apparatus in which the present invention is applied to the simple model described above. The host computer 100 has a function of integrally managing the processing steps, and the printing process section computer 1
The computer 20 for the synthesis process, the computer 30 for the cutting process, the computer 40 for the bag making process, and the computer 50 for the inspection process are connected to the host computer 100 via the network 101. The printing process section computer 10 has three terminal devices 11 to 13 corresponding to the three printing machines 15 to 17, respectively, and the synthesis process section computer 20 has two synthesis devices 25 and 26. Two terminal devices 21 and 22 are provided in the cutting process section computer 30 in correspondence with the two cutting devices 35 and 3 respectively.
6, two terminal devices 31 and 32 correspond to
The bag making process section computer 40 has three bag making machines 45-45.
47 corresponding to each of the three terminal devices 41 to 43
However, the inspection process section computer 50 has two terminal devices 51 corresponding to the two synthesis devices 55 and 56, respectively.
52 are provided respectively. In this embodiment, each of the process section computers 10 to 50 is constituted by a personal computer, and these are directly connected to the host computer 100. However, a plurality of personal computers may be cascaded to have a hierarchical structure. Alternatively, a plurality of computers may be provided in parallel in the same process unit. In addition, a workstation or the like may be provided between each of the processing unit computers 10 to 50 and the host computer 100.

A feature of this management device is that a terminal device is provided for each production machine or for each of a plurality of production machines. For example, in the printing process, three terminal devices 11 to 13 are provided corresponding to the three printing machines 15 to 17, respectively. FIG. 3 shows a more detailed configuration of the process section computer and the terminal device. Here, the configurations of the printing process section computer 10 and the terminal device 11 connected thereto are shown. Printing process section computer 10 connected to tap 101a of network 101
Is the main body 10a, the display device 10b, the printer 1
0c and a network interface unit 10d. In this embodiment, a general personal computer system is used.
The terminal device 11 is connected to the tap 101b of the same network 101 via the network interface unit 11d. The terminal device 11 includes a main body 11a having a built-in display device, a printer 11b, and an operation unit 11c.

FIG. 4 shows details of the operation unit 11c and the printing press 15.
Shown in In the operation unit 11c, in the apparatus of this embodiment, 3
Two operation buttons are provided. That is, a dedicated button A and general-purpose buttons B and C. The dedicated button A is a dedicated button for notifying the existence of a specific processing defect. In the apparatus of this embodiment, a specific processing defect of “connecting” (for example, two winding materials of 500 m are prepared. These operation buttons are assigned to notify the existence of a processing defect that occurs at the joint when these are connected to form a winding material of 1000 m. The general-purpose buttons B and C are buttons for notifying a point in time when various processing defects are found (button B) and a point in time when the processing defects are finished (button C). On the other hand, in the printing press 15, as described above, the take-up material is sent from the paper supply side to the paper discharge side. The printing roller and the like are arranged between the paper supply side and the paper discharge side.

FIG. 5 shows the concept of a printing operation in the printing press 15. The take-up material 1 is set on the paper supply side, pulled out from the leading end, and taken up on the paper discharge side. Printing is
In the middle of this, the operation is performed at the position indicated by the arrow P in the figure.
The relay 15a shown in FIG. 4 has a function of detecting that a new winding material is set on the sheet feeding side. Therefore,
Based on the signal from the relay 15a, it is possible to recognize the order of the currently set winding material. Further, the counter 15b outputs a signal corresponding to the length of the wound material sent from the sheet feeding side (or wound on the sheet discharging side). Specifically, the feed roll on the paper feed side (or the take-up roll on the discharge side)
A rotary encoder or the like may be attached to the device, and the configuration may be such that the pulses output from the rotary encoder are counted. The output signal of the counter 15b is eventually
At a certain point in time, the signal indicates the position of the take-up material on which the printing machine 15 is printing, and specifically, as shown in FIG. 5, indicates a distance L from the leading end of the take-up material.

In this way, information (distance L in FIG. 5) indicating the current processing position of the winding material is sequentially given to the terminal device 11. Further, a signal from the relay 15a and a signal indicating an operation state of each of the buttons A, B, and C are also provided. As described above, the display device is built in the main body 11a of the terminal device. FIG. 6 shows a display screen 60 of the display device. On the left side of the display screen 60, distance display columns 61 and 61 'and index display columns 62 and 6 are provided.
2 ', defect position record columns 63, 63', text column 64,
64 'are provided. The vertical direction of the drawing in each of these columns corresponds to the longitudinal direction of the wound material being processed. In the embodiment shown here, the display corresponds to the winding material having a total length of 400 m, and the numbers 0, 50, 100,..., 400 shown in the distance display columns 61, 61 'are respectively the winding material. Are shown in units of m from the front end of the. Indices indicating the current machining position are displayed in the index display columns 62 and 62 '. When an operator finds a defective portion, the position is entered in the defect position entry columns 63 and 63 ', and the content of the defect is entered as a character string in the text columns 64 and 64'. In the winding identification code column 65, an identification code for specifying the winding material currently being processed is displayed. Under the defect content designation key 66 thereunder, names indicating the contents of various processing defects are displayed. Further, command keys 67a to 67f displayed thereunder are used for inputting information relating to processing defects. With respect to the failure content designation key 66 and each of the command keys 67a to 67f, the operator can perform an input to designate each of these keys. For example, if the screen of the display device is configured by a touch panel, the operator can input an instruction to designate each key by touching the display position of each key on the screen with a hand.

The operation principle of the terminal device 11 is as follows. Now, as shown in FIG. 5, it is assumed that printing on the winding material 1 is performed at the position of the arrow P. The take-up material 1 is sent from the paper supply side to the paper discharge side and is taken up.
The operator monitors whether the printing failure has occurred while watching the position of the arrow P. Then, if a printing failure is found, the user presses the buttons A, B, and C of the operation unit 11c to notify the main body 11a. At this time,
The printing position (distance L) at the present time is determined by the counter 15b.
Can be recognized by the signal from the printer, so that the occurrence position of the printing failure can be automatically specified. Therefore, the operator does not need to input any information regarding the position where the defect has occurred. However, after this, the operator subsequently specifies the defect content specifying key 66 and each of the command keys 67a-67.
Using f, information on the content of the defect that has occurred is input. In this way, the terminal device 11 can create the processing failure data for specifying the content and the position of the processing failure that has occurred. For example, in FIG. 5, it is assumed that the operator has found a dot defect in column 2. In this case, the operator first presses a button on the operation unit 11c to report the discovery position to the terminal device main body 11a. In the case of this example, the “position of the distance L” is recognized as the defect occurrence position. Subsequently, the operator uses the defect content specifying key 66 and each of the command keys 67a to 67f to input the content of the defect that has occurred, that is, "the halftone dot defect has occurred in the column 2". In this way, processing failure data indicating that "halftone dot failure has occurred in the column 2 at the position of the distance L" is created, and this data is transmitted to the host computer 1 via the printing process unit computer 10.
Sent to 00. The operator also operates the printer 10
By using c, 11b, etc., this processing failure data can be stamped out on paper. Since such processing failure data is centrally managed by the host computer 100, it can be used in another terminal device. For example, in the system shown in FIG. 2, the processing defect data created by the terminal device 11 is managed in the host computer 100, so that it can be called from the terminal device 21 and used. When laminating the wound material, which has been printed by the printing machine 15, with the synthesizing device 25,
Thus, it is convenient if the processing failure data created by the terminal device 11 can be used by the terminal device 21. Terminal device 2
In 1, the processing failure data in which the processing failure in the synthesis step is added to the processing failure in the printing step can be created. Further, the terminal device 31 can create processing defect data in which a processing defect in the cutting process is added thereto. If this processing failure data is called and used by the terminal device 51, the inspection device 55 can easily remove the defective portion.

Next, the operation of the present apparatus will be described based on a more specific embodiment. Now, assuming that printing on the winding material 1 is started in the printing press 15, the terminal device 1
The display screen of the display device in 1 is as shown in FIG. In the index display column 62, an index 71 indicating the current printing position is displayed (in this example, the distance L from the leading end of the winding material is around 20 m). The winding material 1 has a total length of 400 m. As the printing process proceeds, the index 71 moves in the index display columns 62 and 62 ′ downward in the figure and moves from 0 m to 400 m. The operator can grasp the progress of the current work by looking at the index 71. In the winding identification code column 65, the identification code of the winding material to be processed (A8823 in this example) is displayed. This identification code may be input by the operator. However, if the host computer 100 gives the operation schedule of each production machine, the host computer 100 can automatically give this identification code. . As described above, the printer 15 is provided with the relay 15a, and it is possible to recognize the number of rolls currently being printed. Therefore, by inquiring the printing schedule held by the host computer 100, It is possible to automatically recognize the identification code of the wound material to be processed. Of course, the operator can freely modify the identification code automatically given as described above.

Now, during this printing operation, the operator monitors whether or not a printing defect occurs. It is assumed that the operator has found a "connection" defect. In this case, the operator presses the dedicated button A of the operation unit 11c shown in FIG. As described above, the dedicated button A is a dedicated button for a "connection" failure. When the terminal device main body 11a detects that the dedicated button A is pressed, as shown in FIG. 8, the defect position display 72 is placed in the defect position record column 63 at the same position as the index 71 at that time.
Is displayed, and a character 73 "connect" is displayed in the text field 64. The index 71 moves downward in the figure with the progress of the printing operation, but the defect position display 72 and the character 73 of "connect" remain displayed at the position shown in FIG. That is, a defect that is “connected” at this position is registered as processing defect data. In this way, the dedicated button A completes all registration just by pressing it. It is convenient to provide such a dedicated button for frequently occurring processing defects.

Next, it is assumed that the operator has found that a defect "dot defect" has continuously occurred in the row 2 of the winding material 1. Thus, it is often seen that the same failure continues over a certain section. In such a case, the operator presses the general-purpose button B of the operation unit 11c shown in FIG. Then, monitoring is continued for a while, and when the defect disappears, the general-purpose button C is pressed. That is, when the occurrence of the "halftone dot defect" is found, the button B is
When the "halftone dot defect" ends, the button C is pressed. FIG. 9 shows a state immediately after performing such an operation. In the defect position record column 63, a start mark 74 is displayed when the button B is pressed, and an end mark 75 is displayed when the button C is pressed. This start mark 7
4 and the end mark 75 are not formal registration as processing defect data, but are merely reference marks. Therefore, the operator performs formal registration later using the reference mark as a guide. This formal registration is performed by the following operation. First, as shown in FIG. 10, a cursor 76 is displayed in the defect position record column 63 using the cursor movement command keys 67a and 67b, and the cursor 76 is first moved to the position of the start mark 74. Then, the user inputs the start command key 67c to set the start position. Subsequently, the cursor 76 in the defect position record column 63 is moved to the position of the end mark 75 using the cursor movement command keys 67a and 67b. Then, a defect content designation key 66 (in this case, “dot defect”
Key). Further, the screen switching command key 67
When f is input, a numeric keypad is displayed on the screen. Here, the column number where the defect has occurred (column 2 in this case) is input. It is also possible to input together with the column number to specify the color in which the dot defect has occurred. Thereby, the formal registration is completed, and the screen display becomes as shown in FIG. The defect position display 77 is displayed in the defect position record column 63 and the text column 64 is displayed.
Displays the character 78 "column 2 / halftone dot failure". As described above, if the start mark 74 and the end mark 75 are displayed by the button input of the operation unit 11c, and the formal registration is performed later using the start mark 74 and the end mark 75, the operability is greatly improved. In this way, the defect “column 2 / halftone dot defect” is registered as the processing defect data at the position indicated by the defect position display 77. It is also possible to cancel the registration by inputting the removal command key 67d or the release command key 67e.

When a defect that exists not only in a certain section but only in a certain place is found, only the start mark 79 needs to be input. For example, if a defect “back-inside” is found in one location, button B may be pressed to display only the start mark 79 as shown in FIG. In this case, formal registration is performed by the following operation. That is, the cursor 76 is displayed in the defect position recording column 63 'using the cursor movement command keys 67a and 67b, and is moved to the position of the start mark 79. Then, the user inputs the start command key 67c, and then continues to input a failure content designation key 66 (in this case, a key of "back-inside") indicating the content of the failure that has occurred. Thereby, the formal registration is completed, and the screen display becomes as shown in FIG. In the defect position record column 63 ', a defect position display 80 is displayed.
The character 81 of “reverse” is displayed at 4 ′.

Thus, if the printing process is completed,
As shown in FIG. 13, three types of printing failures, “linkage”, “row 2 / halftone dot failure”, and “back-transfer” are registered as processing failure data at each position.
This processing failure data is transferred to the host computer 100. Here, it is assumed that a laminating process is performed by the synthesizing device 25 on the wound material that has been printed by the printing machine 15. In this case, the above-described processing failure data created by the terminal device 11 is called by the terminal device 21. That is, the screen equivalent to FIG.
1 display device. However, what should be noted here is that the winding state is reversed between the winding material before the printing step and the winding material after the printing step. That is, the leading end of the winding material before the printing step is the rear end of the winding material after the printing step. As a specific example, for example, as shown in FIG. 13, in the wound material before the printing process, the position where the defect of “connection” occurs is about 40 m from the leading end, On the other hand, in the wound material after the process, the distance is about 40 m from the rear end, in other words, 36 m from the front end.
It is around 0 m. Therefore, when the processing failure data created by the terminal device 11 is called by the terminal device 21, it is necessary to convert the distance such that the front end and the rear end are exchanged. Specifically, the processing failure data created by the terminal device 11 as shown in FIG.
FIG. 14 shows an example.

When the laminating process in the synthesizing device 25 is started, the index 91 starts to move as shown in FIG. The operator monitors the laminating process, and registers a processing defect when it occurs. This registration work is exactly the same as the work in the printing process described above. For example, in the example shown in FIG. 15, a character 93 “column 1 / wrinkle” is displayed in the section indicated by the defective position display 92. As described above, new processing defect information is added so as to overlap with the processing defect in the previous process. On the display screen of the display device, it is preferable to change the display modes of the processing failure in the previous step and the processing failure in the current step so that the processing failure can be distinguished from the processing failure in the current step. For example, various display modes can be adopted, such as changing the display color or displaying only the processing failure in the previous process in reverse.

The operator can easily carry out the work of removing the defective machining portion based on the thus-created defective machining data. For example, if a defective machining portion is to be removed during the bag making process, the defective machining data may be displayed on the terminal device of the bag making process unit, and the process may be performed while referring to the data. In this case, an operation command can be given to the bag making machine based on the processing defect data. For example, if an operation command to stop or decelerate the bag making machine is given, the operator can easily perform the work of removing the defective machining portion. In addition, if an operation command for operating a buzzer or a patrol light is given in order to call attention to the operator, a defective machining portion can be reliably removed.

The above is the configuration and operation of the apparatus for controlling the processing step of a rolled material disclosed in the specification of Japanese Patent Application No. 2-301424. The present invention is a further improvement of this device. Hereinafter, this improvement will be described.

An improvement according to the first invention of the present application is that, in addition to the function of inputting information relating to processing defects of the currently processed winding material to each terminal device, the terminal device is also provided with information on the previously processed winding material. Is to provide a function for inputting information on the processing failure of the above. In the device described above, the operator
Input information on processing defects of the currently processed winding material. For example, in the printing press 15 shown in FIG. 5, the operator monitors whether or not there is a processing defect with respect to the winding material currently being printed, and if there is a processing defect, sends information on the position and content to the terminal device 11. Will be entered. However, actually, since the winding material is flowing from the paper feeding side to the paper discharging side, when the operator finds a processing defect, as described above, the operator first performs an operation of inputting only the position. It will be officially registered later.
More specifically, the button B of the operation unit 11c shown in FIG.
By pressing C, only the reference mark is displayed on the display, and a formal processing defect registration is performed at each reference mark position later.

However, there is a case where there is not enough time for the formal registration. This is for the following reasons. Now, as shown in FIG. 5, one winding material 1 is
When printing while sending paper from the paper feed side to the paper discharge side,
Eventually, the winding material on the paper supply side becomes empty. Therefore, a new take-up material is set on the paper feed side and printing is continued. However, if the printing press is stopped when setting the winding material, it is not preferable because the printing efficiency is reduced. This is a common problem not only in the printing process but also in all other processes. Therefore, in general, in a production machine that performs some processing on a winding material, a mechanism is provided that, when the processing on one winding material is completed, continuously performs processing on the next winding material without stopping the machine. ing. This basic principle is shown in FIG.
That is, two (or three or more in some cases) winding materials 6 and 7 are always set on the sheet feeding side. Then, the material extracted from the winding material 6 is processed, and the processed material is wound up as the winding material 8 on the paper discharge side. When the processing to the end of the winding material 6 is completed in this way, the tip of the winding material 7 is glued to the end of the winding material 6, and as shown by the broken line in the figure, the material drawn from the winding material 7 is removed. To continue processing. In the meantime, the next winding material is set on the roller on which the winding material 6 was located. By repeating such an operation, it is possible to continuously process new winding materials without stopping the production machine.

When such a continuous operation is performed, when the processing of the winding material 6 is changed from the processing of the winding material 6, the relay mounted on the production machine (for example, the relay 15a shown in FIG. 4). Operates, and the display screen 60 of the display device switches from the screen for the winding material 6 to the screen for the winding material 7. In such a case, the operator does not have enough time to formally register the processing defect of the winding material 6. An improvement according to the first invention of the present application is to solve such inconveniences, in addition to a function of inputting information on processing defects of a currently-processed winding material, as well as a winding operation performed in the past. It is provided with a function of inputting information on processing failure of a material. Specifically, a command key for designating the currently processed winding material or the previously processed winding material is provided in the right column of the display screen of the display device shown in FIG. , The display in the left column may be switched. In the case of the above example, the winding material 6
When the processing of the winding material 7 is switched to the processing of the winding material 7, the display screen 60 of the display device switches from the screen for the winding material 6 to the screen for the winding material 7, but the operator has previously processed the winding material. If the command key for designating the material is input, the screen for the winding material 6 is displayed again. Therefore, the operator can perform formal registration with sufficient time.

An improvement according to the second aspect of the present invention is that each terminal device displays a different defect on a display depending on whether it is a full width defect or a partial defect. Here, the full width defect is, as shown in FIG. 17, a processing defect existing over the entire width of the winding material (hatched portion in the figure).
The partial defect refers to a processing defect existing only in a partial position of the entire width as shown in FIG. More specifically, the full width defect shown in FIG. 17 is a processing defect existing over column 1 and column 2, whereas the partial defect shown in FIG. 18 is a processing defect existing only in column 2. . Such a full width defect and a partial defect are handled differently in removing the defective portion. For example, in the process diagram shown in FIG. 1, a full width defect may be removed in any step, but a partial defect having a defect in only one column is preferably removed after the cutting step. It is efficient in that it only removes

Therefore, in the device according to the second invention of the present application,
When the operator inputs the contents of the processing defect to the terminal device, the operator can distinguish between the full width defect and the partial defect and input the contents, and the two are displayed in different forms on the display. More specifically, in the case of a partial defect, the operator performs an input for specifying a column in which the partial defect exists. Therefore, the terminal device can recognize a full width failure when the column is not specified, and a partial failure when the column is specified. For example, as shown in FIG. 19, if the defect is full width, the defect position display 94 is displayed in the defect position recording column 63 to the full width. What is necessary is just to display the defect position display 95. Further, it is preferable that the reference mark for recording the position is also distinguishable from the reference mark. For example, as shown in FIG. 19, the end mark 96 of the full width failure may be displayed as a black triangle, and the end mark 97 of the partial failure may be displayed as a white triangle. With such a display, the operator can grasp the failure mode at a glance.

An improvement according to the third invention of the present application is that an inspection device capable of automatically recognizing a processing defect is attached to each terminal device, and information on the processing defect recognized by the inspection device is transmitted to the terminal device. In addition, a different display is performed between a defect display based on information input from an operator and a defect display based on information input from an inspection device. It is technically difficult to automatically recognize all processing defects with an inspection device. However, if an inspection device is attached to the production machine so that any processing defect can be automatically recognized, an oversight error by the operator can be compensated. Since various types of such inspection devices are known, detailed description thereof is omitted here. For example, if printing is poor, the density of the printed surface of the winding material is measured by an optical sensor, and If the density value deviates from the appropriate range, an inspection device that recognizes a processing failure may be used.

As described above, the defect information from the inspection device and the defect information from the operator are input to the terminal device. The terminal device distinguishes and displays them.
For example, as shown in FIG. 20, the defect display based on the information input by the operator, as described above, displays the defect position display 98 in the defect position record column 63 and outputs the defect based on the information input from the inspection device. The display shows a defective position display 99 in a different form. In this way, by changing the display mode between the two, it is possible to prevent the operator from being confused.

Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to this embodiment, but can be implemented in various other modes. For example, the various display modes on the display shown in the above-described embodiments are merely examples, and various other display modes can be adopted. In addition, as a method of displaying in a different manner in the same display column, in addition to the above-described method, a color, a luminance, a shape, or any other method can be used.
