[0003] [Patent Document 1] JP 2017-159463 A Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, some printers use inks that contain green ink, while other printers do not use inks that contain green ink.

[0005] An object of the present invention is to make the color development of the color gamut using green ink vivid when green ink is used in an inkjet printer capable of using green ink. [Means for solving the problem]

[0006] The inkjet printer disclosed herein includes a plurality of ink containers each containing an ink, a printhead having a plurality of nozzle rows each connected to one of the ink containers, and a control device for controlling the printhead. The control device includes a first storage unit, a registration unit, and a first selection unit. The first storage unit stores a plurality of input ICC profiles including at least a first input ICC profile and a second input ICC profile having a gamut size larger than that of the first input ICC profile in a portion of the color gamut and having a gamut size equal to that of the first input ICC profile in at least another portion of the color gamut. The portion of the color gamut includes an outer shell surface of a gamut having vertices of white, yellow, green, and cyan. The registration unit registers the colors of ink contained in the plurality of ink containers. The first selection unit selects one input ICC profile from the plurality of input ICC profiles stored in the first storage unit based on the color of the ink registered in the registration unit. The first selection unit selects the second input ICC profile when the registered ink includes green ink.

[0007] The inkjet printer is configured to select, when the registered inks include green ink, a second input ICC profile having a larger gamut including the outer surface of a gamut having white, yellow, green, and cyan as apexes than the first input ICC profile as the input ICC profile. The gamut includes the gamut in which green ink is used. Thus, according to the inkjet printer, when green ink is used, the gamut in the color space is expanded, making the color development of the gamut in which green ink is used vivid.

[0009] Hereinafter, an embodiment of an inkjet printer according to the present invention will be described with reference to the drawings. The embodiment described here is, of course, not intended to limit the present invention in any particular way. Furthermore, the same reference numerals are used for members and parts that perform the same functions, and duplicated descriptions will be omitted or simplified.

[0010] FIG 1 is a perspective view of an inkjet printer (hereinafter, printer) 10 according to one embodiment. FIG 2 is a front view showing the main parts of the printer 10. In FIG 1 and FIG 2, the characters L and R indicate left and right, respectively. The characters F and Rr indicate front and rear, respectively. However, these are merely directions for the convenience of explanation, and do not limit the installation mode of the printer 10 in any way.

[0011] The printer 10 is for printing on a recording medium 5. The recording medium 5 is an object onto which ink is ejected. Recording media include not only plain paper and other types of paper, but also materials made of various materials such as resin materials such as polyvinyl chloride (PVC) and polyester, aluminum, iron, and wood.

[0012] The printer 10 includes a casing 2 and a guide rail 3 disposed within the casing 2. The guide rail 3 extends in the left-right direction. A carriage 1 having a recording head 15 that ejects ink engaged therewith is engaged with the guide rail 3. The carriage 1 reciprocates in the left-right direction (scanning direction) along the guide rail 3 by a carriage movement mechanism 8. The carriage movement mechanism 8 has pulleys 19b and 19a disposed on the left and right ends of the guide rail 3. A carriage motor 8a is connected to the pulley 19a. The carriage motor 8a may be connected to the pulley 19b. The pulley 19a is driven by the carriage motor 8a. An endless belt 6 is wound around each of the pulleys 19a and 19b. The carriage 1 is fixed to the belt 6. When the pulleys 19a and 19b rotate and the belt 6 runs, the carriage 1 moves in the left-right direction.

[0013] The recording medium 5 is transported in a paper feed direction by a paper feed mechanism (not shown). Here, the paper feed direction refers to the front-to-rear direction. A platen 4 that supports the recording medium 5 is provided inside the casing 2. A grit roller (not shown) is provided on the platen 4. A pinch roller (not shown) is provided above the grit roller. The grit roller is connected to a feed motor 7 (see FIG. 5). The grit roller is driven and rotated by the feed motor 7. When the grit roller rotates with the recording medium 5 sandwiched between the grit roller and the pinch roller, the recording medium 5 is transported in the front-to-rear direction.

[0014] The printer 10 includes a plurality of ink cartridges 11 each containing an ink. The ink cartridges 11 store inks of different colors. Here, the printer 10 includes eight ink cartridges 11C, 11M, 11Y, 11K, 11W, 11Cl, 11O, and 11G, each storing cyan ink, magenta ink, yellow ink, black ink, white ink, clear ink, orange ink, and green ink. In the technology disclosed herein, the flow of image printing differs depending on whether green ink is used or not, but here, an inkjet printer that includes an ink cartridge that stores green ink and uses green ink will be described. A case where green ink is not used will also be described. Note that the printer 10 is configured to be able to use eight types of ink, but it is not necessary to use all of the eight types of ink described above.

[0015] Of the above inks, cyan ink, magenta ink, yellow ink, and black ink are classified as process color inks that form images, while white ink, clear ink, orange ink, and green ink are classified as special color inks that impart special visual effects to images.

[0016] FIG. 3 is a plan view showing the configuration of the lower surface of the carriage 1. As shown in FIG. 3, the recording head 15 includes a plurality of ink heads 16. Here, the recording head 15 includes four ink heads 16. Each of the four ink heads 16 includes a plurality of nozzles 17. Each of the plurality of nozzles 17 is configured to eject ink. In one ink head 16, the plurality of nozzles 17 form two nozzle rows 18 arranged side by side in the left-right direction. Each nozzle row 18 is composed of a plurality of nozzles 17 arranged side by side in the front-rear direction. Each of the plurality of nozzle rows 18 is connected to one of the plurality of ink cartridges 11C to 11G. Hereinafter, the nozzle row connected to the ink cartridge 11C is referred to as the nozzle row 18C. Hereinafter, similarly, the nozzle rows connected to the ink cartridges 11M, 11Y, 11K, 11W, 11CL, 11O, and 11G are referred to as the nozzle rows 18M, 18Y, 18K, 18W, 18CL, 18O, and 18G.

[0017] The nozzle rows 18C to 18G and the ink cartridges 11C to 11G are connected by ink supply paths 12. The ink supply paths 12 are ink flow paths that supply ink from the ink cartridges 11C to 11G to the nozzle rows 18C to 18G. The ink supply paths 12 are formed of, for example, flexible tubes. The ink supply paths 12 are provided with a liquid feed pump 13. However, the liquid feed pump 13 is not necessarily required and can be omitted. A portion of the ink supply path 12 is covered by a cable protection and guide device.

[0018] The recording head 15 ejects ink toward the recording medium 5, forming ink dots on the recording medium 5. A large number of these dots are arranged to form an image or the like on the recording medium 5. In this embodiment, the nozzles 17 constituting the nozzle row 18C eject cyan ink. The nozzles 17 constituting the nozzle row 18M eject magenta ink. The nozzles 17 constituting the nozzle row 18Y eject yellow ink. The nozzles 17 constituting the nozzle row 18K eject black ink. The nozzles 17 constituting the nozzle row 18W eject white ink. The nozzles 17 constituting the nozzle row 18Cl eject clear ink. The nozzles 17 constituting the nozzle row 18O eject orange ink. The nozzles 17 constituting the nozzle row 18G eject green ink.

[0019] FIG. 4 is a block diagram of the printer 10. As shown in FIG. 4, the control device 100 is electrically connected to the feed motor 7 of the paper feed mechanism, the carriage motor 8a of the carriage movement mechanism 8, the liquid feed pump 13, and the recording head 15. The control device 100 controls the operations of these devices. The control device 100 is typically a computer. The control device 100 includes, for example, an interface (I / F) that receives print data and the like from an external device such as a host computer, a central processing unit (CPU) that executes instructions of a control program, a ROM that stores the program executed by the CPU, a RAM that is used as a working area for expanding the program, and a storage device such as a memory that stores the above program and various data.

[0020] The control device 100 is not limited to devices built into the casing 2 of the printer 10. The control device 100 may also include an external device communicatively connected to the printer 10, such as a computer on which application software is installed. For example, the external computer on which application software is installed may be configured to store a plurality of ICC profiles, which will be described later, and to appropriately select an ICC profile according to printing conditions including the printer model and the ink used.

[0021] 4, the control device 100 includes an ink registration unit 110, a color conversion unit 120, a first storage unit 131, a second storage unit 132, a first selection unit 141, a second selection unit 142, a halftone processing unit 150, and a rasterization processing unit 160. The control device 100 may include other processing units, but illustration and description thereof will be omitted here.

[0022] The colors of ink contained in the ink cartridges 11C to 11G are registered in the ink registration section 110. In this embodiment, cyan ink, magenta ink, yellow ink, black ink, white ink, clear ink, orange ink, and green ink are registered in the ink registration section 110. If any of these inks are not used, the unused ink is not registered in the ink registration section 110.

[0023] The color conversion unit 120 converts device-dependent print image data (here, CMYK ink values, hereinafter also simply referred to as ink values ​​as appropriate) into color values ​​in a device-independent color space (here, L * a * b * Then, the color values ​​in the device-independent color space obtained above (here, L * a * b *The printer converts the device-dependent print image data (color values) into device-dependent print image data (CMYK ink values ​​in this case). When converting device-dependent print image data into color values ​​in a device-independent color space, a conversion table (Look Up Table: LUT) called an A2B table in the color profile is used. Conversely, when converting color values ​​in a device-independent color space into device-dependent print image data, a conversion table called a B2A table in the color profile is used.

[0024] When converting input print image data, the input ICC profile is used. For details, see Converting the ink values ​​of the input print image data to L * a * b * When converting the value, the A2B table of the input ICC profile is used. * a * b * The B2A table of the output ICC profile is used to convert the values ​​into ink values ​​that printer 10 will actually print. ICC profiles include an input ICC profile that converts input print image data, and an output ICC profile that converts the converted and captured print image data into a form that is output by printer 10. The input ICC profile and the output ICC profile each include an A2B table and a B2A table.

[0025] The printer 10 according to this embodiment stores a plurality of input ICC profiles and a plurality of output ICC profiles. The first storage unit 131 stores a first input ICC profile and a second input ICC profile. The first input ICC profile is an input ICC profile that is selected when green ink is not used. When green ink is not used, the case where a printer that does not support green ink is used may be included. The second input ICC profile is an input ICC profile that is selected when green ink is used. Note that the first storage unit 131 only needs to store at least the first input ICC profile and the second input ICC profile, and other input ICC profiles may or may not be stored.

[0026] Figure 5 shows the L * a * b * 5 is a perspective view showing the gamut Gi1 of the first input ICC profile and the gamut Gi2 of the second input ICC profile superimposed in the color space. In FIG. 5, the gamut Gi2 of the second input ICC profile is shown by a solid line, and the gamut Gi1 of the first input ICC profile is shown by a dashed line. C in FIG. 5 indicates the cyan point in the color space. Similarly, M, Y, K, W, O, G, Rd, and B in FIG. 5 indicate the magenta, yellow, black, white, orange, green, red, and blue points in the color space, respectively. The same is true in FIG. 6.

[0027] The gamut Gi1 of the first input ICC profile and the gamut Gi2 of the second input ICC profile are almost overlapped, but as shown in FIG. 5, in some color gamuts, the size of the gamut Gi2 of the second input ICC profile is larger than the gamut Gi1 of the first input ICC profile. The above-mentioned part of the color gamut includes the outer shell surface of the gamut with white W, yellow Y, green G, and cyan C as vertices. More specifically, the white point W on the gamut refers to the point of paper white. The yellow and cyan points Y and C refer to the points of single-color yellow ink (100%) and single-color cyan ink (100%), respectively. The green point G here refers to the point of a color obtained by mixing 100% yellow ink and 100% cyan ink. Note that 100% of a certain ink refers to the maximum amount of that ink. Hereinafter, the outer shell surface of the gamut with white W, yellow Y, green G, and cyan C as vertices will be referred to as the green color gamut A1. In the green gamut A1, the gamut Gi2 of the second input ICC profile is more outwardly convex than the gamut Gi1 of the first input ICC profile.

[0028] In the area other than the green gamut A1, the size of the gamut Gi1 of the first input ICC profile is equivalent to the size of the gamut Gi2 of the second input ICC profile. * The axis ranges from 0 to 100, and * The axis ranges from -128 to 127, and b * This means that the color difference ΔE is within 3 when the axis is in the range of -128 to 127. The color difference ΔE is the distance between two points in a three-dimensional color space. When the color difference ΔE is greater than 3, one color gamut is said to be larger or smaller than the other.

[0029] The second storage unit 132 stores a first output ICC profile and a second output ICC profile. The first output ICC profile is an output ICC profile that is selected when green ink is not used. The second output ICC profile is an output ICC profile that is selected when green ink is used. It is sufficient that the second storage unit 132 stores at least the first output ICC profile and the second output ICC profile, and it does not matter whether or not other output ICC profiles are stored.

[0030] In this embodiment, the first output ICC profile is similar to the first input ICC profile, and the second output ICC profile is similar to the second input ICC profile. * a * b * 6 is a perspective view showing the gamut Gi2 of the second input ICC profile and the gamut Go2 of the second output ICC profile overlapped in the color space. In FIG. 6, the gamut Gi2 of the second input ICC profile is shown by a solid line, and the gamut Go2 of the second output ICC profile is shown by a dashed line. The gamut Gi2 of the second input ICC profile and the gamut Go2 of the second output ICC profile almost overlap. As shown in FIG. 6, the size of the green gamut A1 of the gamut Gi2 of the second input ICC profile is equal to the size of the green gamut A1 of the gamut Go2 of the second output ICC profile. However, the size of at least the red point, the magenta point, and the color gamut around them (hereinafter referred to as the red gamut A2) of the second input ICC profile is larger than that of the second output ICC profile. In the red gamut A2, the gamut Gi2 of the second input ICC profile is more convex toward the outside than the gamut Go2 of the second output ICC profile. The size of the other color gamuts of the gamut Gi2 of the second input ICC profile and the size of the other color gamuts of the gamut Go2 of the second output ICC profile are equal to each other.

[0031] Although not shown in the figure, the relationship between the gamut Gi1 of the first input ICC profile and the gamut of the first output ICC profile is similar to the relationship between the gamut Gi2 of the second input ICC profile and the gamut Go2 of the second output ICC profile. That is, the size of the gamut of the green gamut A1 of the first input ICC profile is equivalent to the size of the gamut of the green gamut A1 of the first output ICC profile. The size of the gamut of the red gamut A2 of the first input ICC profile is larger than the size of the gamut of the red gamut A2 of the first output ICC profile. In addition, the size of the other color gamuts of the gamut Gi1 of the first input ICC profile is equivalent to the size of the other color gamuts of the gamut of the first output ICC profile.

[0032] The first selection unit 141 is configured to select one input ICC profile from the multiple input ICC profiles stored in the first storage unit 131 based on the color of the ink registered in the ink registration unit 110. In detail, when the registered inks include green ink, the first selection unit 141 selects the second input ICC profile. When the registered inks do not include green ink, the first selection unit 141 selects the first input ICC profile.

[0033] The second selection unit 142 is configured to select one output ICC profile from among the multiple output ICC profiles stored in the second storage unit 132, based on the color of the ink registered in the ink registration unit 110. In detail, when the registered inks include green ink, the second selection unit 142 selects the second output ICC profile. When the registered inks do not include green ink, the second selection unit 142 selects the first output ICC profile.

[0034] The halftone processing unit 150 converts the ink values ​​created by the color conversion unit 120 into dot data. Furthermore, the rasterization processing unit 160 converts the dot data created by the halftone processing unit 150 into data for each pass. The printer 10 executes the dot data for each pass created by the rasterization processing unit 160 to perform printing.

[0035] The image printing process in the printer 10 according to this embodiment will be described below. In the example described here, green ink is registered as an ink to be used in the printer 10. Therefore, in the flowchart shown below, the use of green ink is selected. However, if green ink is not registered as an ink to be used, the selection is made not to use green ink.

[0036] Fig. 7 is a flowchart of image printing. As shown in Fig. 7, in step S01, it is determined whether or not green ink is registered as an ink to be used. In the example shown here, the printer 10 is a printer in which green ink is registered as an ink to be used. Therefore, the result of step S01 is YES. As a result, in step S02A, the second input ICC profile is selected as the input ICC profile, and the second output ICC profile is selected as the output ICC profile.

[0037] Conversely, if the printer does not have green ink registered as an ink to be used, the result of step S01 will be NO. In that case, in step S02B, the first input ICC profile is selected as the input ICC profile, and the first output ICC profile is selected as the output ICC profile.

[0038] According to the knowledge of the present inventors, the colors in the green gamut A1 are colors that are relatively difficult for human vision to perceive differences in. Therefore, even if color differences are emphasized in the green gamut A1, the human eye has difficulty perceiving the differences. In addition, if the gamut is excessively expanded in order to increase vividness in the green gamut A1, there is a risk that the reproduction of color gradations will become inaccurate. Therefore, according to the knowledge of the present inventors, in normal cases, the gamut of the green gamut A1 should not be expanded too much in the input ICC profile.

[0039] However, when using green ink as a special color ink, there is an advantage to expanding the color gamut of the green color gamut A1 in the input ICC profile in order to pursue vividness of the green color gamut A1.

[0040] Therefore, the printer 10 according to this embodiment is configured to select, as the input ICC profile, a second input ICC profile having a larger green gamut A1 than the first input ICC profile when green ink is included in the registered inks. This makes it possible to expand the green gamut A1 in the device-independent color space when green ink is used, and to make the colors in the green gamut A1 more vivid.

[0041] On the other hand, the printer 10 according to this embodiment is configured to select the first input ICC profile as the input ICC profile when green ink is not included in the registered inks. This makes it possible to suppress excessive expansion of the green gamut A1 in the device-independent color space when green ink is not used, while making the color development of the green gamut A1 vivid when green ink is used.

[0042] The same is true for the output ICC profile, and the printer 10 according to this embodiment is configured to select, as the output ICC profile, a second output ICC profile having a larger green gamut A1 than the first output ICC profile when the registered inks include green ink. This allows the color reproduction capability of the printer 10 for the green gamut A1 to be fully utilized when green ink is used, and makes the color development in the green gamut A1 vivid. The printer 10 according to this embodiment is also configured to select, as the output ICC profile, a first output ICC profile when the registered inks do not include green ink. This allows an output ICC profile that corresponds to the color reproduction capability of the printer to be used when green ink is not used. This allows accurate color reproduction.

[0043] In this embodiment, the size of the green gamut A1 of the second input ICC profile is equal to the size of the green gamut A1 of the second output ICC profile, so that when color values ​​in the device-independent color space are converted to output ink values ​​of the printer, the colors in the green gamut A1 can be reproduced with high accuracy.

[0044] On the other hand, the second input ICC profile is set so that at least the size of the red gamut A2 is larger than that of the second output ICC profile. As a result, color values ​​in the device-independent color space are converted to the printer's output ink values ​​so that the saturation of the red gamut A2 in the printed image is increased. This makes it possible to express the colors in the red gamut A2 vividly. According to the knowledge of the inventors of the present application, human vision is sensitive to color differences in the red gamut A2, so there is a great advantage to emphasizing vividness. In addition, there is a demand for emphasizing colors such as red and purple depending on the application, and this can be met.

[0045] The same is true for the first input ICC profile and the first output ICC profile that are selected when green ink is not used. That is, the size of the green gamut A1 of the first input ICC profile is equal to the size of the green gamut A1 of the first output ICC profile, and the size of the red gamut A2 of the first input ICC profile is larger than the size of the red gamut A2 of the first output ICC profile. The effects are similar to those of the second input ICC profile and the second output ICC profile.

[0046] In the image printing process, as shown in Fig. 7, input image data is converted to output ink values ​​of the printer 10 using the selected input and output ICC profiles in step S03. Then, halftone processing is performed in step S04, and rasterization processing is performed in step S05. The data obtained in these steps is then executed in step S06. This completes the print image.

[0047] Although a preferred embodiment has been described above, the inkjet printer of the present invention is not limited to the above embodiment.

[0048] For example, in the above embodiment, the second input ICC profile has a larger gamut than the first input ICC profile in the green gamut and is equal to the first input ICC profile in other gamuts, but is not limited to this. The second input ICC profile may have a larger gamut than the first input ICC profile in some gamuts including the green gamut, and may have a gamut equal to the first input ICC profile in at least some other gamuts. In other words, the gamut in which the gamut of the second input ICC profile is larger than that of the first input ICC profile may include the green gamut, and is not limited to the green gamut. In addition, a gamut in which the gamut of the first input ICC profile is larger than that of the second input ICC profile may be included in a gamut other than the green gamut. The same applies to the gamut of the first output ICC profile and the gamut Go2 of the second output ICC profile.

[0049] In the above embodiment, the size of the red gamut A2 of the second input ICC profile Gi2 and the gamut Go2 of the second output ICC profile differ, but they may be the same. The same is true for the gamut Gi1 of the first input ICC profile and the gamut of the first output ICC profile.

[0050] Furthermore, in the above embodiment, the gamut size of the gamut Gi2 of the second input ICC profile and the gamut Go2 of the second output ICC profile are equal in color gamuts other than the green gamut A1 and the red gamut A2, but the gamut size may not be equal in some or all of the color gamuts. In some or all of the other color gamuts, the gamut size of the second input ICC profile may be larger than the gamut size of the second output ICC profile. Or, in some or all of the other color gamuts, the gamut size of the second input ICC profile may be smaller than the gamut size of the second output ICC profile. The same applies to the gamut Gi1 of the first input ICC profile and the gamut of the first output ICC profile.

[0051] In the above embodiment, there is described as one input ICC profile when green ink is used, one input ICC profile when green ink is not used, one output ICC profile when green ink is used, and one output ICC profile when green ink is not used; however, sets of these may be stored for each printing condition, such as resolution.

[0052] The configuration of the printer 10 according to the embodiment described above is an example, and is not intended to limit the configuration of the printer.

[0053] Unless otherwise specified, the above-described embodiments do not limit the present invention. [Explanation of symbols]
