As shown in fig. 3, an embodiment of the present invention provides an intelligent digital printing method, which is applied to a control device 20, and the method includes:
step S301, a target pattern and a first image of an object to be printed, which is acquired by an image acquisition device, are acquired.
When a printing merchant needs to print an object to be printed, a position to be printed of the object to be printed needs to be determined first, then a first image of the position to be printed of the object to be printed is acquired through the image acquisition device 10, after the first image is acquired, a target pattern which needs to be printed at the position to be printed needs to be acquired, and the target pattern can be selected from a network by the merchant, designed by a designer or designed by a user, and then sent to the merchant for printing.
In some other embodiments, in order to make the image of the to-be-printed object captured by the image capturing device clear, the printing apparatus further includes an illumination unit, where the illumination unit may be any device with an illumination function, such as an LED lamp, an incandescent lamp, and the like, and preferably, the LED lamp is selected, because light emitted by the LED lamp does not generate heat, and does not affect a nozzle of the printing unit, and also does not affect ink properties of a color pattern of the to-be-printed object, thereby affecting pattern quality. When the merchant needs to shoot, the lighting unit is firstly turned on, and the first image collected by the image collecting device can be ensured to be clearer.
In other embodiments, the ink dots can be better printed on the object to be printed after the subsequent ink-jet printing, so that the printing quality is improved, and the treatment liquid can be sprayed on the position to be printed of the object to be printed before the first image is shot.
Step 302, obtaining a base color based on the first image, and obtaining a target color based on the target pattern.
In order to make the printing effect better, the image acquisition device sends the first image and the target pattern to the control device after acquiring the first image and the target pattern, the control device starts image processing software, such as raster image processing software, after receiving the first image and the target pattern, identifies the first image and the target pattern, acquires the color of the first image from the first image as a base color, and acquires the color of the target pattern from the target pattern as a target color.
And step S303, matching the basic color and the target color with a pre-stored color card, and generating a matching result.
And after the image processing software obtains the primary color of the first image and the target color of the target pattern, matching the primary color and the target color with a color card in a color card table database in the image processing software so as to obtain a matched result.
In other embodiments, as shown in fig. 4, the matching the base color and the target color with a pre-stored color chart and generating a matching result specifically includes:
step 401, matching the primary colors with a special color card in the pre-stored color cards, and determining a first special color area in the primary colors.
Since the region of the spot color in the primary color cannot be directly printed during printing, the region of the spot color in the primary color needs to be determined, and the colors in the primary color need to be distinguished. Firstly, comparing the primary colors in the first image with a special color card of a color card in the image processing software, and determining a special color area in the primary colors as a first special color area by comparing the primary colors with the special color card.
And step S402, matching the target color with a spot color card in the pre-stored color cards, and determining a second spot color area in the target color.
When a target pattern is printed on an object to be printed, the spot color in the target color cannot be obtained by mixing different colors, so that the spot color area in the target color needs to be determined. And comparing the target color with the special color card of the color card in the image processing software, and determining that the special color area in the target color is a second special color area by comparing the target color with the special color card.
Step S403, matching the target color with a color separation color card in the pre-stored color card, and determining a second color separation region in the target color and second color separation data corresponding to the second color separation region, where the second color separation region is a region of the target color except for a second special color region.
Since the color separation in the target color can be obtained by mixing different colors, it is necessary to determine the color separation region in the target color. And comparing the target color with a color separation color card in the color card stored in the image processing software to determine that a color separation area in the target color is a second color separation area. And after the second color separation area is determined, determining second color separation data of the second color separation area according to color separation data corresponding to a color separation card in the image processing software.
Step S404, determining a third spot color region in the base color according to the first spot color region and the second spot color region, where the third spot color region is a union of a corresponding region of the second spot color region in the base color and the first spot color region.
In order to avoid repeated printing and waste of ink, after a first special color area and a second special color area are obtained, as a target pattern corresponds to the area outline of the first image, the corresponding position of the second special color area in a primary color can be found according to the second special color area, a third special color area in the primary color is determined according to the corresponding position of the second special color area in the primary color and the first special color area, and the third special color area is the union of the corresponding areas of the first special color area and the second special color area in the primary color.
Step S405, matching a first color separation region in the primary color with a color separation color card in the pre-stored color card, and determining first color separation data of the first color separation region, wherein the first color separation region is a region of the primary color except for the third special color region.
After the third special color area in the primary color is obtained, color separation data of the color separation area in the primary color needs to be obtained, the area except the third special color area in the primary color is used as a first color separation area, the first color separation area is matched with a color separation card of a color card in image processing software, and the first color separation data of the first color separation area is determined according to the color separation data corresponding to the color separation card in the image processing software.
And step S304, selecting a printing mode according to the matching result, and controlling the printing equipment to perform printing operation according to the printing mode.
And after the control device selects the printing mode, the control device controls the printing equipment to perform corresponding printing operation according to the selected printing mode.
In other embodiments, when the printing area in the primary color is the third spot color area, the white background printing mode is selected, and when the printing area in the primary color is the first color separation area, the corresponding printing mode is selected for printing according to the first color separation data in the first color separation area and the second color separation data corresponding to the second color separation area.
In other embodiments, the spot and separation regions of the base and target colors are not fixed, for example, the base color of the region to be printed on the object to be printed may be all spot colors, all separations, or a combination of spot and separation. The target color of the target pattern may be a full separation, a spot color, and a combination of separations.
In some embodiments, the white background printing mode is divided into a first white background printing mode and a second white background printing mode, when a corresponding area of a first special color area and a second special color area in a primary color is a continuous area, the first white background printing mode is adopted for the third special color area, that is, a layer of white background is printed in the third special color area, then a corresponding special color nozzle is called according to a special color in an area corresponding to the third special color area in the target color to print a special color pattern, and after the special color pattern is printed, a k cmy nozzle is called according to second color separation data in an area corresponding to the third special color area in the target color to print a color separation pattern.
When the corresponding areas of the first spot color area and the second spot color area in the third spot color area in the primary color are discontinuous, a second white background printing mode is adopted for the third spot color area, namely, a layer of white background is printed in the corresponding area of the third spot color area and the second spot color area, and then the corresponding spot color spray head is called according to the spot color of the second spot color area to print a spot color pattern. After the special color patterns are printed, printing a layer of white background on the area corresponding to the third special color area and the second color separation area, and calling the corresponding CMYK spray heads to print the color separation patterns according to the second color separation data of the second color separation area.
In other embodiments, since the color separations in the primary color and the target color may be obtained by different color mixtures, at least one set of first color separation data of the primary color first color separation region and second color separation data of the target color second color separation region may include multiple sets of color data according to the image complexity. And when the first color separation data is smaller than the second color separation data, adopting a decrement printing mode for the area where the first color separation data is smaller than the second color separation data, namely printing according to the difference value of the first color separation data and the second color separation data. Since the color separations in the primary color and the target color are obtained by mixing C (cyan) M (magenta) Y (yellow) K (black) in different proportions, the above-described four colors are explained here. For example, the first color separation data corresponding to the first color separation region in the primary colors is C (20%) M (50%) Y (50%) K (10%), the second color separation data corresponding to the first color separation region in the target colors is C (30%) M (70%) Y (50%) K (20%), at this time, since the printing mode adopted is the decrement printing mode, the difference between the first color separation data and the second color separation data is C (10%) M (20%) Y (0%) K (10%), after the difference between the two is calculated, the CMYK inkjet head is called to perform the corresponding printing operation on the first color separation region according to the difference, that is, the ink output of C (cyan) is 10% of the normal value, the ink output of M (magenta) is 20% of the normal value, and the difference between Y (yellow) is 0%, so that the first color separation data of the first color separation region and the Y (yellow) in the second color separation data of the second region are explained as the first color separation data of the first color separation region and the second color separation region Accordingly, no ink was discharged in Y (yellow) and the ink discharge amount of K (black) was 10% of the normal value, and thus ink jet printing was performed to form a target pattern.
When at least one item in the first color separation data is larger than the second color separation data, selecting a color matching printing mode, namely adding white ink to a region corresponding to a data item of which the first color separation data is larger than the second color separation data according to the difference of the data items of the first color separation data and the second color separation data, and adopting a decrement printing mode for the region corresponding to the data item of which the first color separation data is smaller than the second color separation data. For example, the first color separation data is C (20%) M (50%) Y (50%) K (10%), the second color separation data is C (10%) M (60%) Y (60%) K (20%), the data item larger than the second color separation data in the current first color separation data is C (cyan) from the first color separation data and the second color separation data, therefore, it is necessary to add white ink to the region corresponding to C (cyan) so that C (cyan) in the first color separation data is also C (10%), the difference between the first color separation data and the second color separation data is C (10%), therefore, the white ink with 90% -110% of the difference C (10%) between the two is needed to be added to make the effect of C (cyan) in the first color separation data and the effect of C (cyan) in the second color separation data approximate, other color separation data items are printed according to the decrement printing mode, that is, the corresponding CMYK heads are called up for printing according to M (10%) Y (10%) K (10%).
In other embodiments, when the data item in the first color separation data is larger than the data item in the second color separation data, a third white background printing mode may be further selected, that is, a white ink nozzle is called to print a layer of white background in the first color separation area, and then a corresponding CMYK nozzle is called to print according to the second color separation data of the second color separation area corresponding to the first color separation area.
