The printable processed watermark object may include a text watermark, such as a digital watermark, an alphabetic watermark, a text watermark, and the like, and an image watermark, such as an icon watermark, a picture watermark, a logo watermark, and the like. The non-watermark object is other information needing to be printed, and specifically can be other characters needing to be printed except the watermark object. For example, in an application scenario of printing an express bill containing a watermark object, the non-watermark object may be, for example, express information to be printed, and the express information may include, for example, a sender name, a sender address, a sender phone number, a recipient name, a recipient address, a recipient phone number, cargo information, and the like.
When an original layer containing a watermark object is generated, an independent layer is defined, the layer is used for placing characters or patterns which are shown as watermark effects, and the characters or patterns which are used as the watermark object are added into the layer to obtain the original layer containing the watermark object. The original image layer is composed of a plurality of pixel points, each pixel point has a second color characteristic, and the second color characteristic comprises a brightness characteristic of at least one preset primary color. Illustratively, the second color characteristic is an RGB color characteristic, which includes luminance characteristics of three primary colors of red, green, and blue.
In operation S220, the initial layer is subjected to a rasterization process to obtain a watermark dot matrix layer.
According to the embodiment of the invention, the initial layer is subjected to the dot matrix processing to obtain the watermark dot matrix layer containing the watermark object, specifically, at least one pixel point is selected from the preset area containing the watermark object of the initial layer according to the preset rule, and the following operations are executed aiming at the selected pixel point: determining a first color characteristic of at least one pixel point, wherein the first color characteristic comprises an initial chromaticity characteristic, an initial saturation characteristic and an initial brightness characteristic; and performing chromaticity adjustment processing on the initial chromaticity characteristics of the pixel points according to the first color characteristics of the pixel points, wherein at least one pixel point after the chromaticity adjustment processing forms a watermark dot matrix layer.
Or determining a first color characteristic of each pixel point in a preset region of the initial layer containing the watermark object, wherein the first color characteristic comprises an initial chromaticity characteristic, an initial saturation characteristic and an initial brightness characteristic; selecting at least one pixel point from a preset area containing a watermark object of the initial layer according to a preset rule, wherein the pixel point has a first color characteristic, and executing the following operations aiming at the selected pixel point: and performing chromaticity adjustment processing on the initial chromaticity characteristics of the pixel points according to the first color characteristics of the pixel points, wherein at least one pixel point after the chromaticity adjustment processing forms a watermark dot matrix layer.
The method for determining the first color feature of the pixel point may include: and according to the second color characteristic of the pixel point, performing color characteristic conversion processing on the pixel point to obtain the first color characteristic of the pixel point. The first color feature may be, for example, an HSB color feature that characterizes a color by using three color features of Hue (Hue), Saturation (Saturation), and lightness (Brightness). The Hue (Hue) represents the type of color (e.g., red, green, or yellow), and ranges from 0 to 360, and each Hue feature represents a color. The Saturation (Saturation) represents the Saturation of a color, and ranges from 0 to 1, the Saturation of 0 represents a gray scale map, and the Saturation of 1 represents a pure color. Lightness (Brightness) represents the Brightness of a color, and ranges from 0 to 1, lightness of 0 represents black, and lightness of 1 represents a color of a specific saturation.
The method for obtaining the HSB color feature by performing color feature conversion processing on the pixel point according to the RGB color features of the pixel point can be implemented according to the following conversion relationship, for example.

B＝max
Where R, G, B denotes a red luminance value, a green luminance value, and a blue luminance value, respectively, max denotes a maximum luminance value in R, G, B, and min denotes a minimum luminance value in R, G, B.
And selecting at least one pixel point from a preset region containing the watermark object of the initial layer according to a preset sparse lattice algorithm, so as to convert the initial layer into a sparse lattice layer. Specifically, in each pixel point row or each pixel point column of the preset area, pixel points of every preset number of pixels are selected to obtain at least one pixel point. As an optional mode, in a preset region containing a watermark object, according to each pixel point row of the preset region, pixel points of every preset number of pixels are selected from one row end to the other row end line by line. Illustratively, in each pixel point row of the preset area from top to bottom, at least one pixel point every 4 pixels is selected from left to right line by line. As another optional mode, in a preset region containing the watermark object, pixel points of every preset number of pixels are selected from one row end to the other row end line by line according to each pixel point row of the preset region. Illustratively, in each pixel point column from left to right of the preset area, at least one pixel point every 4 pixels is selected from top to bottom column by column. When the pixel points are selected, the preset number of the pixels can be a value, a plurality of values, or a value adjusted according to the first color characteristic of the pixel points.
The preset region may be any region of the initial layer that includes the watermark object, specifically, may be a whole region of the initial layer, or may be a partial region of the initial layer that includes the watermark object. The embodiment of the invention can determine the first color characteristics of all the pixel points in the preset area, and then select part of the pixel points from all the pixel points to carry out initial chromaticity characteristic adjustment processing. The design is favorable for determining which pixel points are selected to carry out initial chromaticity characteristic adjustment processing according to the first color characteristics of the determined pixel points. Generally, the pixels with the initial saturation characteristic and the initial brightness characteristic larger than the preset threshold may be selected to perform the initial chromaticity characteristic adjustment process. In addition, a part of pixel points can be selected in a preset area, the first color characteristics of the part of pixel points are determined, and then the initial chromaticity characteristic adjustment processing is carried out on the part of pixel points. The design is favorable for reducing the workload of color characteristic conversion processing and improving the efficiency of watermark printing processing by determining the first color characteristics of partial pixel points.
Aiming at least one selected pixel point, carrying out chromaticity adjustment processing on the initial chromaticity characteristic of the pixel point according to the first color characteristic of the pixel point, wherein at least one pixel point after the chromaticity adjustment processing forms a watermark dot matrix layer. Specifically, discretization can be performed on the initial chromaticity characteristics of each pixel point, the initial chromaticity characteristics of each pixel point are converted into target chromaticity characteristics, and the initial chromaticity characteristics of each pixel point are converted into chromaticity characteristics with stable printing effect. The method is favorable for realizing stable printing effect and better printing quality when different printers are used for carrying out watermark printing, does not need to spend a large amount of time and energy to set watermark parameters of different printers, and is favorable for reducing the implementation cost of the watermark printing technology.
When a printer is used for printing characters, the characters in the dot matrix data form are imaged to be in a pure color state, all character areas are covered by the toner, the influence of the toner concentration and the image transparency on the character printing effect is not required to be considered, the printing effect is stable, and the printing quality is good. Therefore, the original chromaticity characteristics of the watermark object can be considered to be adjusted, the watermark object can be processed into the dot matrix data with the same character effect, and when the printer is used for printing the watermark object in the dot matrix data form, the influence of the watermark parameter setting of the printer on the printing effect of the watermark object can be avoided.
In operation S230, the watermark dot matrix layer is superimposed with other information layers to be printed, so as to obtain an object to be printed including the watermark object.
According to the embodiment of the invention, when the watermark dot matrix layer and other information layers to be printed are superposed, the watermark dot matrix layer can be arranged on the bottom layer, and then the other information layers to be printed are superposed on the watermark dot matrix layer to obtain the object to be printed containing the watermark object.
The other information to be printed may be dot matrix data or data described in a Printer Language (Printer Language Description data, abbreviated as PLD data). When the other information is dot matrix data, the other information layers are dot matrix layers containing non-watermark objects, and the printer can directly acquire the dot matrix data from the dot matrix layers for printing. When the other information is the PLD data, various print control instructions in the PLD data can be analyzed to convert the PLD data into dot matrix data, that is, the other information layer is converted into a dot matrix layer containing a non-watermark object.

Fig. 3 schematically shows a flowchart of another processing method capable of realizing watermark printing according to an embodiment of the present invention.
As shown in fig. 3, the method is applied to a terminal including at least one application program that can be executed. The method may include operations S310 to S330.
In operation S310, an initial layer containing a watermark object is generated.
According to the embodiment of the present invention, the principle and process of operation S310 may refer to the principle and process of operation S210, which is not described herein again.
In operation S320, according to the first color feature of at least one pixel point in the initial layer, a chroma adjustment process is performed on each pixel point, and the at least one pixel point after the chroma adjustment process forms a watermark dot matrix layer.
According to the embodiment of the present invention, the method for determining at least one pixel point in the initial layer and determining the first color feature of the pixel point in the initial layer may refer to the principle and process of operation S220, which is not described herein again.
The first color feature of the pixel point comprises an initial chromaticity feature, an initial saturation feature and an initial brightness feature, and specifically comprises an initial chromaticity value, an initial saturation value and an initial brightness value. When the chromaticity of the pixel point is adjusted, the preset chromaticity characteristic of the pixel point is determined according to the initial chromaticity characteristic in the first color characteristic of the pixel point, and then the target chromaticity characteristic of the pixel point is determined according to the initial chromaticity characteristic and the preset chromaticity characteristic of the pixel point.
When the preset chrominance characteristic of the pixel point is determined according to the first color characteristic of the pixel point, the preset chrominance characteristic is determined to be the first chrominance characteristic or the second chrominance characteristic according to the first color characteristic of the pixel point, wherein the first chrominance characteristic indicates the background color of other information layers, and the second chrominance characteristic indicates the color of the watermark object. And then, determining a target chromaticity characteristic for the pixel point according to the initial chromaticity characteristic and the preset chromaticity characteristic for the pixel point. Specifically, determining whether the initial chromaticity characteristics meet preset conditions; if so, taking the preset chromaticity characteristic as a target chromaticity characteristic; and if not, taking another chromaticity characteristic except the preset chromaticity characteristic as the target chromaticity characteristic in the first chromaticity characteristic and the second chromaticity characteristic.
When the preset chrominance characteristic of the pixel point is determined according to the first color characteristic of the pixel point, the preset chrominance characteristic can be determined to be a second chrominance characteristic under the condition that the difference value between the initial chrominance characteristic and the first chrominance characteristic is greater than a first preset value, the initial saturation characteristic is greater than a second preset value, and the initial brightness characteristic is greater than a third preset value; and determining the preset chromaticity characteristic as the first chromaticity characteristic under other conditions.
Because the chromaticity represents the type of the color, each chromaticity characteristic represents a color (that is, each chromaticity value represents a color), and when the difference value between the initial chromaticity characteristic of the pixel point and the chromaticity characteristics of the background colors of other information layers is greater than a first preset value, it is indicated that the color of the pixel point is different from the background colors of other information layers, even the difference is larger. At this moment, whether the initial saturation characteristic and the initial brightness characteristic of the pixel point are larger than a preset threshold value or not is continuously determined, when the initial saturation characteristic and the initial brightness characteristic are both larger than the preset threshold value, the saturation and the brightness of the color of the pixel point are determined to be higher, and at this moment, the initial color characteristic of the pixel point is converted into a second color characteristic. When the pixel point subjected to the chrominance characteristic conversion processing is the pixel point of the watermark object, the initial color characteristic of the pixel point is not processed; and when the pixel point is not the pixel point of the watermark object, setting the color of the pixel point as the color of the watermark object. The values of the first, second and third preset values can be adjusted according to the printing effect of the historical object to be printed containing the watermark object, and the values of the three preset values have flexibility and are not uniquely determined.
Optionally, when the initial chromaticity characteristic of the pixel is not the first chromaticity characteristic, the initial saturation characteristic is greater than the second preset value, and the initial brightness characteristic is greater than the third preset value, the preset chromaticity characteristic is determined to be the second chromaticity characteristic. Namely, when the color of the pixel is not the background color of other information layers and the saturation and the brightness of the color of the pixel are high, the color of the pixel is set as the color of the watermark object. And determining the preset chromaticity characteristics of the pixel points as the first chromaticity characteristics under other conditions.
Optionally, the background color of the other information layers indicated by the first chrominance characteristic is white, and the color of the watermark object indicated by the second chrominance characteristic is black. At this time, whether the color of the pixel point is white is judged firstly, and if the color of the pixel point is white, the initial chromaticity characteristic of the pixel point is not processed. If the color is not white, determining whether the initial saturation value of the color of the pixel point is greater than 0.5 or not, and determining whether the initial brightness value of the color of the pixel point is greater than 0.5 or not, and when the initial saturation value and the initial brightness value of the color of the pixel point are both greater than 0.5, determining that the preset chromaticity characteristic aiming at the pixel point is black; and if the initial saturation value or the initial brightness value of the color of the pixel point is not more than 0.5, determining that the preset chromaticity characteristic aiming at the pixel point is white.
And after the preset chromaticity characteristics aiming at each pixel point are determined, continuously determining the target chromaticity characteristics aiming at each pixel point according to the initial chromaticity characteristics and the preset chromaticity characteristics of each pixel point. Specifically, the target chromaticity characteristic of each pixel point is determined to be the first chromaticity characteristic or the second chromaticity characteristic according to whether the initial chromaticity characteristic of each pixel point meets the preset condition. That is, after the preset chromaticity characteristics for each pixel point are determined, further adjustment processing is performed on the chromaticity characteristics of each pixel point. The preset condition is adjustable according to the printing effect of the historical object to be printed containing the watermark object, and the preset condition is flexible to select and is not uniquely determined.
In the field of printing technology, the colors of printed matter are often represented using a CMYK printing color scheme. The CMYK mode is different from the RGB mode in that the RGB mode is a color mode in which a screen display emits light, and the CMYK mode is a color mode in which a printed matter relies on light reflection. The image displayed on the screen is expressed by the RGB mode, and the image expressed in the printed matter is expressed by the CMYK mode. In order to confirm the printed colors before actual printing, the colors of the printed matter may be collated with reference colors, and generally, the colors of the printed matter may be collated with color spectrums, which are presented by multiplying the colorimetric values of each color by 10% of density, and increasing or decreasing by 10 grids. Therefore, the CMYK values in a general printing technology are multiples of 10, and thus colors exactly corresponding to the CMYK values can be found in a color spectrum. In the case of relaxing the criteria, it is also possible to take the CMYK value as a multiple of 5. Therefore, the preset condition in the embodiment of the present invention may be selected to determine whether the initial chroma value of the pixel is a multiple of 5 or 10.
Illustratively, it is determined whether the initial chrominance value of the pixel point is a multiple of 5, that is, the initial chrominance value of the pixel point is left over by 5. When the remainder is 0, taking the preset chromaticity characteristic as the target chromaticity characteristic of the pixel point; if not, in the first chrominance characteristic and the second chrominance characteristic, the other chrominance characteristic except the preset chrominance characteristic is used as the target chrominance characteristic of the pixel point. Specifically, under the condition that the first chromaticity characteristic indicates white and the second chromaticity characteristic indicates black, when the remainder is 0 and the preset chromaticity characteristic of the pixel point is white, determining that the target chromaticity characteristic of the pixel point is white; and when the preset chromaticity characteristic of the pixel point is black, determining that the target chromaticity characteristic of the pixel point is black. When the remainder is not 0 and the preset chromaticity characteristic of the pixel point is white, determining the target chromaticity characteristic of the pixel point to be black; and when the preset chromaticity characteristic of the pixel point is black, determining that the target chromaticity characteristic of the pixel point is white.
The initial chroma feature of each pixel point is converted into the target chroma feature by performing sparse dot matrix processing on the initial layer containing the watermark object and performing chroma feature adjustment processing on the pixel points after the sparse dot matrix processing, and specifically, the initial chroma feature of each pixel point is converted into the chroma feature of the background color of other information layers or is converted into the chroma feature of the watermark object color. The method comprises the steps of carrying out dot matrix processing on an initial layer containing a watermark object to realize processing of the watermark object into discrete pixel points, then representing the shape of the watermark object by utilizing the target chromaticity characteristics of each pixel point, and realizing representation of the watermark object by a group of two-dimensional pixel information.
In operation S330, the watermark dot matrix layer is superimposed with other information layers to be printed, so as to obtain an object to be printed including the watermark object.
According to the embodiment of the invention, the initial layer containing the watermark object is subjected to the dot matrix processing to obtain the watermark dot matrix layer, and then the watermark dot matrix layer is superposed with other information layers to obtain the object to be printed containing the watermark object. The watermark effect presented after the object to be printed is basically the same as the presentation effect of directly printing the watermark object in the traditional watermark layer mode. When treating the printing object and printing, treat that the watermark object in the printing object is equivalent to ordinary printing typeface, according to the printing requirement of ordinary printing typeface, can realize the printing to the watermark object, this is favorable to effectively reducing the requirement to printing equipment, do not require printing equipment to have the watermark function of printing even, this kind of design is favorable to guaranteeing the stability of watermark printing effect, and improves the watermark printing effect, and can need not to spend a large amount of time energy to carry out the setting of printing equipment watermark parameter, be favorable to improving watermark printing efficiency, and reduce watermark printing cost consumption.
