(A2) Printing process:
Next, print processing performed by the CPU 102 in the printing system 10 will be described. FIG. 3 is a flowchart illustrating the flow of print processing performed by the CPU 102. The printing process is started when the user instructs printing on the application program 30.

  When the printing process is started, the CPU 102 transfers the image data ORG recorded in the print description language to the printer driver 50 as the application program 30 (step S102).

  Here, the image data ORG will be described. FIG. 4 is an explanatory diagram for explaining the image data ORG corresponding to the print target image. As described above, the image data ORG is image data generated by the image generation application program. A plurality of images (hereinafter also referred to as content images) are included in the area of the print target image (image data ORG). The content image P1 shown in FIG. 4 is an image (color image) that can be expressed by a combination of basic colors, and data (hereinafter also referred to as pixel data) of each pixel constituting the content image P1 is R (red), Each color component value (0 to 255) of G (green) and B (blue) is recorded. In addition, objects such as line drawings and figures included in the content image P1 are recorded as vector data.

  The content image P2 is an image expressed using metallic luster. The content image P2 is configured by superimposing two layer images of layer 1 and layer 2. Each pixel data constituting the layer 1 is recorded with R, G, and B color component values. Layer 2 is an image expressed in metallic luster, and each pixel data is recorded with a metallic (Mt) color component value. In this embodiment, the color component values of Mt recorded in all the pixel data constituting the layer 2 are the same value (for example, 90). Similarly to the content image P1, objects such as line drawings and figures included in the layers 1 and 2 are recorded as vector data.

  The content image P3 is an image expressed using a texture. The content image P3 is configured by superimposing two layer images of layer 3 and layer 4. Each pixel data constituting the layer 3 is recorded with R, G, and B color component values. Layer 4 is an image represented by a texture. Layer 4 is a number that defines the type of texture specified by the user in the image generation application (hereinafter also referred to as texture number TX), a number that specifies the texture color (hereinafter also referred to as texture color number TXC), It is defined by vector data that specifies the area to which the texture is applied. The CPU 102 specifies the texture of the layer 4 by reading the texture specified by the texture number TX and the texture color number TXC from the texture library 71 described in detail later. Also in layer 3, objects such as line drawings and figures included in the layer are recorded as vector data.

  The description returns to the flow of the printing process (see FIG. 3). After the image data ORG described above is transferred from the application program 30 to the printer driver 50 in the form of a description language for printing (step S102), the CPU 102 functions as a function of the printer driver 50 according to the description language. Is interpreted (step S104). The CPU 102 interprets the image data ORG as each content image P1 to P3, each layer 1 to 4, the color component value of the content image or layer, the texture number TX, the texture color number TXC, and further each content image and the inside of the layer. Interpret the line drawings and figures in a way that can be identified. That is, the image data ORG is interpreted as a set of a plurality of objects.

  After interpreting the image data ORG, the CPU 102 generates data corresponding to the print target image (hereinafter also referred to as drawing data PCD) in a data format suitable for processing in the printer driver 50 based on the information of each object. . For this purpose, first, a texture based on the texture number TX and the texture color number TXC interpreted from the image data ORG is read from the texture library 71 (step S106). FIG. 5 is an explanatory diagram for explaining the texture library 71. The texture library 71 includes a texture table 72 that associates the texture number TX with the texture type, and a texture color index 73 that associates the texture color number TXC with the color applied to the texture. Based on the texture number TX and the texture color number TXC, the CPU 102 refers to the texture table 72 and the texture color index 73 and specifies the texture to be applied to the layer 4 (FIG. 4) of the content image P3.

  After specifying the texture to be applied to the image data ORG, the CPU 102 generates the drawing data PCD based on the interpretation of the image data ORG (step S108). Information related to objects other than texture, such as the content images P1 to P3, the layers 1 to 4, the content image and the color component values of the layers, is obtained by interpreting the image data ORG, and the drawing data PCD is generated.

After the drawing data is generated, the CPU 102 displays, as a function of the drawing data generation module 52, a print target image as the drawing data PCD on the display 90 through the video driver 40 so that the user can visually recognize it (step S110). The user visually recognizes the print target image on the display 90, and adjusts the color (brightness, saturation, hue), texture, and metallic luster of the print target image as the drawing data PCD via the keyboard 91 and the mouse 92. Is possible. Hereinafter referred texture of printed images, the degree of metallic luster and texture.

  FIG. 6 is an explanatory diagram illustrating an example of the texture adjustment screen displayed on the display 90 by the CPU 102. The texture adjustment screen 93 includes an adjustment image display unit 94 that displays a print target image corresponding to the drawing data PCD that is a texture adjustment target, and a texture selection unit 95 that is used when the user selects and changes the texture type. The texture color selection unit 96 used for selecting and changing the texture color, the color adjustment slider 97 for adjusting each color component value (R, G, B) of each content image and layer, and the degree of metallic luster are adjusted. A metallic feel adjustment slider 98, a print execution icon PB for starting printing, and a print processing end icon FB for ending the printing process. The user individually selects an object such as a line drawing or figure in each of the content images P1 to P3 in the image displayed on the adjustment image display unit 94, and determines the texture type and color, the color component value, and the metallic luster. The degree can be changed using a texture adjustment operation unit such as the texture selection unit 95 or the texture color selection unit 96. Further, the CPU 102 displays the changed print target image on the adjustment image display unit 94 in real time every time the user adjusts the texture.

CPU102 from the user, a keyboard 91, when accepting an instruction of adjusting the texture via the mouse 92 (step S112: texture change) according to the instruction contents of the adjustment of the texture from the user, the drawing data PCD, each object, increase or decrease in the degree of metallic luster, make changes color to the type of texture and applications (step S114).

  When the user finishes adjusting the texture of the print target image and operates the print execution icon PB provided on the texture adjustment screen 93, the CPU 102 receives an instruction to execute printing (step S112: print execution), and the color conversion module. As a function 54, the R, G, B, and Mt color component values recorded in the respective pixel data of the drawing data PCD after adjusting the texture are used as the ink amounts (C, M, and Y) of the ink colors provided in the printer 200. , K, Lc, Lm, Mt) is performed (step S116).

  The color conversion process is performed by the CPU 102 using the C-LUT 74, the MtC-LUT 76, and the Mt1D-LUT 77. The C-LUT 74 is used when color conversion is performed on pixel data (color component value: RGB) belonging to a region of a content image that can be expressed by a combination of basic colors such as the content image P1 and the content image P3. This is a dimension lookup table. A set of (C, M, Y, K, Lc, Lm) ink quantity sets is stored in the grid points of the C-LUT 74 determined by a set of (R, G, B) values. FIG. 7A is an explanatory diagram illustrating the characteristics of the C-LUT 74 by taking the ink amounts of cyan (C) and light cyan (Lc) as examples. As shown in FIG. 7A, the C-LUT 74 uses dark color ink (cyan (C) in FIG. 7A) and light color ink (FIG. 7A) for RGB color component values. Then, an ink amount set is determined using light cyan (Lc) together. For this reason, for example, when pixel data (color component value: RGB) belonging to a region of a content image that can be expressed by a combination of basic colors such as the content image P1 and the content image P3 is input, collation with the C-LUT 74 is performed. Thus, the ink amount set is obtained by adding light color ink (LcLm) to dark color ink (CMYK).

  The MtC-LUT 76 is used when performing color conversion on each pixel data of a layer (color component value: RGB) superimposed on a metallic layer (layer 2) like the layer 1 in the content image P2. It is a three-dimensional lookup table. A set of (C, M, Y, K) ink amount sets is stored at the lattice points of the MtC-LUT 76 determined by a set of (R, G, B) values. FIG. 7B is an explanatory diagram for explaining the characteristics of the MtC-LUT 76. As shown in FIG. 7B, the MtC-LUT 76 determines an ink amount set only for dark color inks (CMYK) with respect to RGB gradation values. Therefore, for example, when pixel data belonging to layer 1 is input, it is converted into an ink amount of dark color ink (CMYK) by collation with MtC-LUT76.

  In addition, when the color component values in the RGB format are the same between the C-LUT 74 and the Mt-LUT 76, the total amount of color ink converted after each LUT is smaller in the MtC-LUT 76. It is stipulated in. This is due to the knowledge that the area expressed using the metallic ink can achieve color development with a small amount of color ink compared to the area expressed using only the color ink ( JP, 2010-52225, A). In addition, because there is a limit on the maximum amount of ink that can be ejected per unit area of the print medium, the area of the content image from which color ink and metallic ink are ejected is the amount of color ink in consideration of the amount of metallic ink. This is because it is necessary to determine.

  The Mt1D-LUT 77 performs color conversion on each pixel data of the metallic layer (color component value: Mt) such as the layer 2. FIG. 7C is an explanatory diagram illustrating characteristics of the Mt1D-LUT 77. The Mt1D-LUT 77 is a one-dimensional lookup table that converts a metallic (Mt) color component value in each pixel data of the drawing data PCD into an ink amount of metallic ink. As can be seen from FIG. 7C, the maximum value of the output ink amount is limited to 30 with respect to the input value (color component value of Mt). This is due to the knowledge that metallic ink does not change the degree of metallic luster even when a predetermined amount or more of ink is ejected per unit area. The predetermined maximum ink amount is defined as a value of 30 in this embodiment.

  Using the C-LUT 74, MtC-LUT 74, and Mt1D-LUT 77 described above, the CPU 102 performs color conversion on each pixel data constituting the drawing data PCD into ink amount data in which the ink amount is recorded in each pixel data. Thereafter, as a function of the halftone module 55, the CPU 102 performs a halftone process in which the ink amount data is represented by a dot distribution to generate dot data (step S118). In this embodiment, a halftone process is performed by employing a dither method using a dither matrix. Also, other halftone processing methods such as an error diffusion method may be employed. Since the dither method and the error diffusion method are well-known techniques, description thereof is omitted.

  After the halftone processing, as a function of the interlace module 56, the CPU 102 rearranges the dot arrangement of the generated dot data in the order to be transferred to the printer 200, outputs the print data to the printer 200, and starts printing. Various commands such as a command and a print end command are output to the printer 200 (step S120), and printing is executed in the printer 200 (step S122).

  After executing printing, the CPU 102 displays the texture adjustment screen described with reference to FIG. The user visually recognizes the print image printed on the print medium P, confirms the texture of the print image, and when it is necessary to adjust the texture again, the texture is adjusted on the texture adjustment screen displayed on the display 90. Can be adjusted.

  On the other hand, when the user visually recognizes the printed image and the target texture is expressed, the user operates the print processing end icon FB, so that the CPU 102 terminates the print processing. An instruction is accepted (step S112: end), and a screen for confirming whether or not to save the texture change contents such as the texture type, color, and color component value set by the user as file data is displayed on the display 90. Then, when the user selects to save the texture change content, the CPU 102 saves the texture change content such as the texture type, color, and color component value set by the user as one file data in the HDD 80 (step S102). S124: Yes / Step S126). Thereafter, the CPU 102 ends the printing process. If the user wants to print the image data ORG again with the same texture, the user does not need to perform another texture change setting operation on the texture adjustment screen 93 and saves it on the printer driver 50 earlier. By reading the file data in the texture change, printing can be executed with the same change contents, and a print image with the target texture can be obtained.

  As described above, in the printing system 10, the printer driver 50 interprets the description language for printing and controls the texture of the image data received from the application program 30 for each object. The texture of the image to be printed can be controlled without using. Therefore, even when the texture desired at the time of image generation differs from the texture of the printed image after printing, the texture can be adjusted on the printer driver. In addition, when the user performs multiple times of texture adjustment and confirmation, such as “print image output → texture confirmation, → texture adjustment → print image output ...”, the user must Can be performed on the printer driver, so that it is possible to easily perform the texture adjustment operation a plurality of times without the need to start the application driver again and to perform operations on the application driver.

  Furthermore, the printing system 10 can adjust the degree of metallic gloss as the special gloss. In addition, the MtC-LUT 76 and Mt1D-LUT 77 take into account the maximum ink amount per unit area in the print medium, and the ink amount is stored at each grid point. In the obtained printed image, ink bleeding can be suppressed.

  As a correspondence relationship with the claims, the language interpretation module 51 and the drawing data generation module 52 correspond to the drawing data conversion unit described in the claims, and the texture control module 53, the color conversion module 54, and the halftone module. 55, the interlace module 56 corresponds to the texture control unit described in the claims.

B. Variations:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

In the above embodiment, the printer driver 50 interprets the image data ORG according to the print description language, and then controls the texture of the data (drawing data) before the change to the ink amount data. The texture may be controlled after conversion to the quantity data.

In the above embodiment, a part or all of the functions (modules) performed by the CPU 102 as the application program 30 and the printer driver 50 may be performed by a RIP (Raster image processor) as software installed in the computer 100. RIP as hardware connected to the computer 100 and the printer 200 may be performed.

In the above embodiment, the degree of metallic gloss can be adjusted as the special gloss, but for example, as the special gloss ink, a pearl white ink having a pearl white texture, a transparent or translucent clear ink expressing gloss, etc. When special glossy ink is employed, it is possible to adjust the degree of special gloss such as the degree of pearl white or the gloss of the image to be printed as the texture adjustment.

In the above embodiment, the Mt1D-LUT 77 is used when converting the metallic (Mt) color component value into the ink amount of the metallic ink, but one set of (R, G, B, Mt) values and one set are used.
