Description

Technical Field

[0001] The present invention relates to the field of inkjet printing technology, and in particular to a printing method, device, equipment and storage medium for determining an ink output mode based on color separation. Background Art

[0002] At present, as people's requirements for printing colors become more and more stringent, most manufacturers have begun to use ICC files for color calibration printing. In the existing ICC printing processing method, although the addition of ICC processing will improve the color restoration, when performing ICC printing, the color on the printed product will appear mottled, affecting the quality of printing. Especially in the light color area of ​​the printed product, it is more likely to appear mottled, resulting in low printing quality, affecting the appearance of the product and the value of the printed product. For example, in textile printing, when the ICC color separation data corresponding to a certain area is C color data, M color data, Y color data, and K color data, the so-called fractional data is the ink volume data of each color, but when a certain color data is less than a certain value, mottled color will appear. For example, when the K color data is less than 5, black particles will appear on the printed product, and mottled color will appear in the printed light color area such as the face. To address this problem, the technical means currently used in the field of inkjet printing technology is to directly remove the color separation data corresponding to the area that is less than a certain value, and not to print the color separation data of the area that is less than a certain value. However, this technical means will cause the problem of inaccurate printing color of the printed product. Summary of the invention

[0056] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish an entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Thus, the feature of being limited to "first", "second" can expressly or implicitly include one or more of these features. In the description of the present embodiment, unless otherwise specified, the meaning of "multiple" is two or more. Moreover, the term "include", "comprise" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only include those elements, but also include other elements not clearly listed, or also include elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0058] In the field of inkjet printing technology, there is a certain color corresponding to a certain printing area. Because the amount of ink is too little, the ink dots are too scattered when they fall on the printing area after printing, causing mottled colors in the printing area, affecting the printing quality.

[0059] Example 1

[0060] See also Figure 1 The embodiment of the present invention provides a printing method for determining an ink output mode based on color separation, the method comprising:

[0061] S1: Acquire image data;

[0062] S2: Acquire first color separation data according to the image data;

[0063] S3: obtaining a preset threshold, and obtaining an ink discharge mode according to the first color separation data and the preset threshold, wherein the ink discharge mode includes: linearized ink discharge or ICC ink discharge;

[0064] S4: Controlling inkjet printing according to the ink discharge mode.

[0065] The printing method, device, equipment and storage medium for determining the ink discharge mode based on color separation provided by the embodiment of the present invention obtain image data, obtain first color separation data according to the image data, obtain a preset threshold, obtain the ink discharge mode according to the first color separation data and the preset threshold, the ink discharge mode includes: linearized ink discharge or ICC ink discharge, and control inkjet printing according to the ink discharge mode. Different ink discharge modes are selected according to the preset threshold and the first color separation data, ensuring that the first color separation data is inkjet printed according to different ink discharge modes, ensuring that the occurrence of color noise is reduced in the factor area, improving the printing quality, ensuring the printing aesthetics of the printed product, and improving the value of the printed product.

[0066] In one embodiment, if Figure 2 As shown, the step S2: obtaining first color separation data according to the image data includes:

[0067] S21: Acquire image data;

[0068] S22: Acquire color data according to the image data;

[0069] S23: Acquire first color separation data according to the color data.

[0070] Specifically, the image data is image data to be printed, and the image data can be obtained by scanning the image to be printed, or can be an electronic picture; the color data is the color of different image areas on the image data obtained by processing the image data; the first color separation data is obtained based on the color data, and the first color separation data includes four colors of C, M, Y, and K or three colors of R, G, and B.

[0071] In one embodiment, if Figure 3 As shown, the S3: obtaining a preset threshold, obtaining an ink discharge mode according to the first color separation data and the preset threshold, the ink discharge mode including: linear ink discharge or ICC ink discharge; including:

[0072] S31: Obtaining a preset threshold;

[0073] S32: Acquire second color separation data according to the first color separation data;

[0074] S33: Acquire an ink output mode according to the second color separation data and the preset threshold.

[0075] Specifically, the first color separation data is processed, and the second color separation data is obtained after the processing. When printing, when controlling the printing device to print, the first color separation data needs to be processed according to the parameters of the printing device to ensure the accuracy of the color of the printed product when the printing device prints.

[0076] The second color separation data is four sub-color separation data of C, M, Y, and K.

[0077] The preset threshold is obtained based on printing experience. When one color separation data in the CMYK four-color separation data is smaller than the preset threshold, the ink dots corresponding to the color separation data will cause noise during printing, resulting in noise.

[0078] Each printing area corresponds to a second color separation data, and the second color separation data is the ink volume data of the corresponding printing area. The ink discharge mode corresponding to the printing area is obtained according to the second color separation data and the preset threshold.

[0079] like Figure 4 , Figure 5 , Figure 6 As shown, Input is the first color separation data, and Unedited is the second color separation data after processing the first color separation data.

[0080] Figure 4 The C color data and the M color data in the data value decrease after processing, while the Y color data and the K color data increase after processing; Figure 5 The C color data, the M color data, and the Y color data increase after processing, while the K color data decreases after processing; Figure 6 The C color data, the M color data, and the Y color data are reduced after being processed, while the K color data is increased after being processed.

[0081] The embodiment of the present invention determines whether the second color separation adopts a linearized ink outlet mode or an ICC ink outlet mode through the second score and the preset threshold, thereby ensuring that the second color separation data is inkjet printed according to the most suitable ink outlet mode, eliminating or reducing noise in the printing area, ensuring the printing effect of the printing area, and improving the printing quality of the printing area.

[0082] In one embodiment, if Figure 7 As shown, the step S32: obtaining second color separation data according to the first color separation data includes:

[0083] S321: linearizing the first color separation data to obtain first color data;

[0084] S322: Perform ICC processing on the first color separation data to obtain second color data;

[0085] S323: Acquire the second color separation data according to the first color data and the second color data.

[0086] Specifically, obtaining the second color separation data includes: performing linearization processing on the first fractional data; and performing ICC processing on the first color separation data. The first color data and the second color data obtained after the processing will have certain differences in numerical values.

[0087] In one embodiment, if Figure 8 As shown, the step S33: obtaining the ink output mode according to the second color separation data and the preset threshold value includes:

[0088] S3311: Compare the first color data with the preset threshold to obtain a comparison result;

[0089] S3312: When the comparison result is that the first color data is greater than or equal to the preset threshold, the ink discharge mode is linear ink discharge;

[0090] S3313: Compare the second color data with the preset threshold to obtain a comparison result;

[0091] S3314: When the comparison result is that the second color data is greater than or equal to the preset threshold, the ink output mode is ICC ink output.

[0092] Specifically, the ink output mode is obtained according to the second color separation data and the preset threshold value by comparing the first color data and the second color data in the second color separation data with the preset threshold value respectively. When the comparison result is that the first color data is greater than or equal to the preset threshold value or the second color data is greater than or equal to the preset threshold value, the first color data controls the nozzle to perform linearized ink output printing; the second color data controls the nozzle to perform ICC ink output printing.

[0093] The embodiment of the present invention can ensure that the second color separation data is inkjet printed according to the most suitable ink discharge mode, eliminate or reduce the noise in the printing area, ensure the printing effect of the printing area, and improve the printing quality of the printing area.

[0094] In another embodiment, if Fig. 9 As shown, obtaining the comparison result includes:

[0095] S301: Acquire sub-color data in the first color data and the second color data;

[0096] S302: comparing the sub-color separation data with the preset threshold;

[0097] S303: when there is a sub-color data of the first color data that is smaller than the preset threshold, determining that the first color data is smaller than the preset threshold;

[0098] S304: When there is a sub-color data in the second color data that is smaller than the preset threshold, it is determined that the second color data is smaller than the preset threshold.

[0099] Specifically, when one or more of the sub-color data in the first color data or the second color data corresponding to the printing area is smaller than the preset threshold, it is determined that the first color data is smaller than the preset threshold and the second color data is smaller than the preset threshold.

[0100] The first color data includes four sub-color separation data of C, M, Y, and K, and the second color data includes four sub-color separation data of C, M, Y, and K. That is, when the K sub-color separation data in the first color data or the K sub-color separation data in the second color data is less than the preset threshold, it is determined that the first color data or the second color data is less than the preset threshold, that is, the second score data is less than the preset threshold.

[0101] like Fig.10 As shown, in one embodiment, the step S33: obtaining the ink output mode according to the second color separation data and the preset threshold value includes:

[0102] S3321: when the first color data is greater than or equal to the preset threshold, the ink output mode of the first color data is linear ink output;

[0103] S3322: When the first color data is less than the preset threshold, perform ICC processing on the first color to obtain the second color data;

[0104] S3323: When the second color data is greater than or equal to the preset threshold, the ink output mode of the second color data is ICC ink output.

[0105] Specifically, firstly, the first score data is linearized to obtain the first color data, and it is determined whether the first color data is greater than or equal to the preset threshold value. When the first color data is greater than or equal to the preset threshold value, the nozzle is controlled to perform linear ink printing according to the first color data; when the first color data is less than the preset threshold value, it is determined that if the nozzle is controlled to perform linear ink printing according to the first color data, it will cause the printing area to have a color noise phenomenon.

[0106] When the first color data is less than the preset threshold, the first color data is processed by ICC to obtain the second color data, and the second color data is compared with the preset threshold to determine whether the second color data is greater than or equal to the preset threshold. When the second color data is greater than or equal to the preset threshold, the nozzle is controlled to perform ICC ink printing according to the second color data.

[0107] If the first color data and the second color data corresponding to the printing area are both smaller than the preset threshold, the sub-color data in the first color data or the second color data that is smaller than the preset threshold can be directly canceled, or the second color data can be compared with the first color data, and the first color data or the second color data whose sub-color data is closest to the preset threshold can be selected, and inkjet printing can be performed according to the corresponding linearized ink output mode or ICC ink output mode.

[0108] The ICC processing includes the linearization processing.

[0109] The first color data and the second color data respectively include four sub-color data, namely C color data, M color data, Y color data, and K color data.

[0110] In one embodiment, the step S4: controlling inkjet printing according to the ink output mode comprises:

[0111] S41: when the ink discharge mode is linearized ink discharge, controlling the nozzle to perform linearized ink discharge printing according to the first color data;

[0112] S42: When the ink discharge mode is ICC ink discharge, the nozzle is controlled to perform ICC ink discharge printing according to the second color data.

[0113] The embodiment of the present invention first determines whether the first color data corresponding to the printing area will cause the mottle phenomenon by using the linearized ink printing. If the mottle phenomenon will not occur, the first color data is subjected to linearized ink printing; if the mottle phenomenon will occur, the first color data is subjected to ICC processing, and it is determined whether the second color data obtained after the processing will cause the mottle phenomenon. If the mottle phenomenon will not occur, the second color data is subjected to ICC ink printing. Because the ICC processing includes the linearization processing, it is first determined whether the first color data of the printing area will cause the mottle phenomenon by printing. If the mottle phenomenon will occur, it is then determined whether the second color data of the printing area will cause the mottle phenomenon. This reduces the data processing steps to a certain extent, saves time and effort, and eliminates or reduces the mottle phenomenon of the printing area during printing.

[0114] The printing method, device, equipment and storage medium for determining the ink discharge mode based on color separation provided by the embodiment of the present invention obtain image data, obtain first color separation data according to the image data, obtain a preset threshold, obtain the ink discharge mode according to the first color separation data and the preset threshold, the ink discharge mode includes: linearized ink discharge or ICC ink discharge, and control inkjet printing according to the ink discharge mode.
