[0002] In an image forming device, the print head prints out data based on the CMYK color space, while the print task is often issued as data in the RGB color space.

[0049] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0050] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0051] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0052] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0053] Figure 1 The flowchart of a printing method provided by an embodiment of the present invention. The method can be applied to an intelligent terminal that issues printing tasks, such as a personal computer, a tablet computer, a mobile phone, etc. Figure 1 As shown in , the method includes:

[0054] Step 101, determining the category of the printing element.

[0055] The printing element refers to an element constituting a printing task, for example, each character and each pattern in the manuscript are printing elements. The types of printing elements may include character type, image type, and graphic type. Before determining the type of the printing element, all printing elements in the printing task may be acquired cyclically. After acquiring all printing elements in the printing task, the types of each acquired printing element are determined.

[0056] Step 102: Determine a target rendering mode from multiple rendering modes according to the type of the print element.

[0057] The rendering mode refers to the process of converting logical drawing (i.e., printing element) into raster data based on the interface function, which can also be called drawing. Different types of printing elements require different rendering modes for rendering. For example, for text-type printing elements, the text-type rendering mode needs to be called. For image-type printing elements, the image-type rendering mode needs to be called. For graphic-type printing elements, the graphic-type printing elements need to be called.

[0058] Step 103: Render the print element using the target rendering mode to obtain first raster data.

[0059] In some embodiments, while looping to obtain each print element in the print task, the attribute information of each print element can be obtained. The attribute information of the print element can specifically include one or more combinations of information such as size, color, position, original image, and zoomed image. For example, for a text-type print element, the text attribute information can be obtained. The text attribute information can include the size, color, and position of the text. For an image-type print element, the image attribute information can be obtained. The image attribute information includes the original image, zoomed image, size, and position of the image. For a graphic-type print element, the graphic attribute information can be obtained. The graphic attribute information can include the color, size, and position of the graphic.

[0060] After the attribute information of the printing element is acquired, the attribute information may be rendered to the printing element in a target rendering manner, so that the printing element is rendered in the form of an image to obtain corresponding first raster data.

[0061] In some embodiments, the attribute information can be rendered to the print element by calling the native engine function of the operating system of the device. The engine function is a core function of the operating system, which is used for graphics device interface (GDI) rendering. Using the native engine function of the operating system for rendering can improve the compatibility of the printing method provided by the embodiment of the present invention. Specifically, after determining the target rendering mode corresponding to the print element, the operating system engine function corresponding to the target rendering mode is determined. Different rendering modes correspond to different operating engine functions. The print element is then rendered by the operating system engine function to obtain the first raster data.

[0062] Step 104: perform identification processing on the first raster data according to the type of the printing element to obtain second raster data with identification information.

[0063] The identification processing can be implemented in the form of adding a corresponding label to the first raster data. For example, for a text-type printing element, a first label can be added to the first raster data corresponding to the printing element. For an image-type printing element, a second label can be added to the first raster data corresponding to the printing element. For a graphic-type printing element, a third label can be added to the first raster data corresponding to the printing element, thereby performing identification processing on all the printing elements contained in the acquired printing task.

[0064] Step 105: Determine a target color space conversion strategy from a plurality of color space conversion strategies according to the identification information of the second raster data.

[0065] Different types of printing elements use different color space conversion strategies, so as to improve the final printing effect. Therefore, the type of the printing element can be determined by identifying the identification information of the second raster data, and then the target color space conversion strategy to be adopted can be determined.

[0066] After the first raster data corresponding to all the printing elements are marked, a plurality of second raster data corresponding to the plurality of printing elements are obtained. Then, the target color space conversion strategy corresponding to each second raster data is determined according to the marking information in the second raster data, so as to convert the raster data from the RGB color space into the CMYK color space used for printing by the image forming device.

[0067] Step 106 , performing color space conversion on the first raster data according to the target color space conversion strategy to obtain third raster data.

[0068] The second raster data is obtained after dyeing based on the first raster data. The second raster data is only used to determine the color space conversion strategy. When executing the color space conversion, the first raster data needs to be color converted.

[0069] The third raster data obtained after the color space conversion is the raster data of the CMYK color space. Then the third raster data is sent to the image forming device. After receiving the third raster data, the image forming device can directly print out according to the third raster data.

[0070] In some embodiments, the identification processing of the first raster data in step 104 can also be implemented in the form of dyeing the first raster data. Specifically, the association relationship between different types of printing elements and different identification colors can be pre-established. Then, the identification color corresponding to the type of the printing element can be determined according to the type of the printing element and the pre-established association relationship. For example, for a text-type printing element, the corresponding identification color can be color A. For an image-type printing element, the corresponding identification color can be color B. For a graphic-type printing element, the corresponding identification color can be color C. Then, the first raster data is dyed with identification according to the determined identification color to obtain second raster data with dyed identification. Among them, the first raster data before identification dyeing and the second raster data after identification dyeing are different only in color.

[0071] For example, three printing elements are obtained, namely: printing element A, printing element B and printing element C. The identification color corresponding to the text type is preset to be red, the identification color corresponding to the pattern type is preset to be green, and the identification color corresponding to the graphic type is preset to be blue. Among them, the category of printing element A is text type, specifically the text "A", and the color is black. The category of printing element B is pattern type, specifically a circular pattern, and the color is red. The category of printing element C is graphic type, specifically a rectangular shape, and the color is purple. Then, after rendering printing element A, Figure 2-a After rendering the print element B, we get Figure 2-b After rendering the print element C, we get Figure 2-c The first raster data shown in FIG. Then the identification color corresponding to the printing element A is red. Figure 2-a The first raster data shown in FIG. 1 is dyed red to obtain Figure 3-a The second raster data shown in FIG. The identification color corresponding to the printing element B is green. Figure 2-bThe first raster data shown in FIG. 1 is dyed green to obtain Figure 3-b The third raster data shown in FIG. The identification color corresponding to the printing element C is blue. Figure 2-c The first raster data shown in FIG. 1 is dyed with blue to obtain Figure 3-c The second raster data shown in .

[0072] Afterwards, when determining the color space conversion strategy, the type of the printing element can be identified according to the color of the second raster data, and then the corresponding target color space conversion strategy can be determined. Specifically, color space conversion strategies corresponding to different dyeing identifiers can be established in advance, and different dyeing identifiers correspond to different color space conversion strategies. Afterwards, the corresponding target color space conversion strategy can be determined from multiple color space conversion strategies according to the dyeing identifier of the second raster data.

[0073] In some embodiments, a rendering raster may be created in advance, and the rendering raster includes a print rendering raster A and a print mask raster B. The print rendering raster A is used to store the first raster data. The print mask raster B is used to store the second raster data. The print rendering raster A and the print mask raster B are both implemented in the form of storage addresses. That is, the print rendering raster A is a collection of several first raster data forms. The print mask raster B is a collection of several second raster data forms. The print rendering raster A and the print mask raster B are not actual storage or memory, but virtual storage space for storing raster data.

[0074] Corresponding to the content of the above embodiment, the embodiment of the present invention provides another implementation process of the printing method. Figure 4 FIG. 1 is a flow chart of another printing method provided by an embodiment of the present invention. Figure 4 As shown in , the method includes:

[0075] Step 401, obtaining a printing element.

[0076] Step 402, determining whether the type of the printing element is a text type, if so, executing step 403, if not, executing step 404.

[0077] Step 403, obtaining attribute information of the text type.

[0078] Step 404, determine whether the type of the print element is an image type. If yes, execute step 405, if not, it means the type of the print element is a graphic type, execute step 406.

[0079] Step 405: Obtain attribute information of the image type.

[0080] Step 406, obtaining attribute information of the graphic type.

[0081] Step 407 , calling the text type operating system engine function to render into the first raster data and output to the print rendering raster A.

[0082] Step 408: Mark the first raster data of the text type in the print rendering raster A as identification color A.

[0083] Step 409 , calling the operating system engine function of the image type to render into the first raster data and output to the print rendering raster A.

[0084] Step 410 : Mark the first raster data of the image type in the print rendering raster A as identification color B.

[0085] Step 411 , calling a graphics type operating system engine function to render into first raster data and output to a print rendering raster A.

[0086] Step 412: Mark the first raster data of the graphic type in the print rendering raster A as identification color C.

[0087] Step 413: Render the first raster data in the print rendering raster A according to the identification color to obtain second raster data, and output it to the print mask raster B.

[0088] Among them, the operating system engine function of the text type can be called to render the first raster data marked as identification color A in the print raster A as the second raster data. The operating system engine function of the image type can be called to render the first raster data marked as identification color B in the print raster A as the second raster data. The operating system engine function of the graphic type can be called to render the first raster data marked as identification color C in the print raster A as the second raster data.

[0089] Step 414, determine whether the color of the second raster data in the print mask raster B is color A, if yes, execute step 415. If no, execute step 416.

[0090] Step 415: Use the text type color space conversion strategy to obtain the third raster data.

[0091] Step 416, determine whether the second raster data in the print mask raster B is the identification color B. If yes, execute step 417. If no, it indicates that it is the identification color C, execute step 418.

[0092] Step 417, using the image type color space conversion strategy to obtain third raster data.

[0093] Step 418: Use the graphic type color space conversion strategy to obtain the third raster data.

[0094] Step 419: output the third raster data to an image forming device.

[0095] In some embodiments, the image forming device has two ways to print black, one is to use black toner to print directly, that is, pure black. The other is to use blue toner, magenta toner and yellow toner to synthesize black for printing, that is, color black. For progressive colors, using the color black method can ensure that the color transition of the printing effect is more natural, and for text or vector graphics, pure black is used, and the color effect is better. Therefore, the user can make specific settings according to the desired printing effect, thereby indicating whether the image forming device uses a pure black strategy or a color black strategy. Specifically, the printing configuration information can be obtained first. The printing configuration information is determined according to the black output strategy set by the user. The user sets the black output strategy of the print task to a pure black strategy or a color black strategy. Then, the corresponding printing configuration information is obtained according to the black output strategy set by the user. The intelligent terminal determines the output strategy of the printing element according to the printing configuration information. The output strategy of the printing element corresponds to the black output strategy set by the user, including a mixed color output strategy (i.e., color black) or a pure color output strategy (i.e., pure black). Then, the output strategy is sent to the image forming device. The image forming device uses color toner to print and output the third raster data according to the mixed color output strategy. Alternatively, the image forming apparatus prints out the third raster data using black toner according to a solid color output policy.

[0096] In some embodiments, the method of dyeing and marking the first raster data in the embodiments of the present invention can also be used to filter printing elements. For example, for a scene where only text-type printing elements are output, the second raster data in the print mask raster B can be filtered according to the color of the second raster data, and only the second raster data of the color A corresponding to the text type is retained. Then, the corresponding first raster data is searched from the print rendering raster A according to the second raster data of the color A remaining in the print mask raster B, and the color space conversion is performed to generate the third raster data containing only the text-type printing elements. The third raster data is sent to the image forming device for printing and output, and finally a printed manuscript containing only text is obtained.

[0097] Corresponding to the above-mentioned printing method, an embodiment of the present invention provides an intelligent terminal. Figure 5 The following is a schematic diagram of the structure of an intelligent terminal provided by an embodiment of the present invention.

[0098] The printing category determination module 501 is used to determine the category of the printing element.

[0099] The rendering mode determining module 502 is used to determine a target rendering mode from multiple rendering modes according to the type of the print element.

[0100] The rendering module 503 is used to render the print element using a target rendering mode to obtain first raster data.

[0101] The identification module 504 is used to perform identification processing on the first raster data according to the type of the printing element to obtain second raster data with identification information.
