With the advent of the information age, the way of performing information processing on data such as characters, pictures, and face sheets has become more and more popular. The electronic data obtained by the information processing is also widely used in applications such as copyright protection, authentication, data tracking and the like.

In implementing the disclosed concept of the present invention, the inventors found that, due to different watermark parameter settings of different printers, the perceptibility of the same watermark parameter by different printers is also different, which results in different printing effects of the watermark when electronic data with the same watermark is printed by different printers.

This results in poor watermark printing effects on the one hand and in a significant amount of time and effort being expended to set watermark parameters for different printers on the other hand, which significantly increases the labor costs involved in watermark printing.

It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principle of the present invention, and the embodiments of the present invention are not limited in any way. Rather, embodiments of the invention may be applied to any scenario where applicable.

Fig. 2 schematically shows a flow chart of a processing method that may enable watermark printing according to an embodiment of the invention.

As shown in fig. 2, the method is applied to a terminal including at least one application program executable. The method 200 may include operations S210-S230.

In operation S210, an initial layer containing a watermark object is generated.

According to the embodiment of the invention, after receiving a print request from a print request device, print content, print identification information, and print apparatus information in the print request are determined. The print request device may be a smart phone, a tablet computer, a laptop, etc., and software capable of requesting to print a file, for example, office software, pdf software, notepad software, etc., is installed in the print request device. The print identification information may specifically be user terminal information, user login information, print time information, or the like. The printing device information indicates device information for watermark printing, and the printing device can be specifically a thermal printer, a thermal transfer printer, a needle printer, an inkjet printer and the like, and it is noted that the implementation of the printing function by what mode does not affect the implementation of the present invention.

The print content is data to be printed including watermark objects and non-watermark objects. The printable watermark object may include a text watermark, such as a digital watermark, a letter watermark, a text watermark, etc., and an image watermark, such as an icon watermark, a picture watermark, logo watermark, etc. The non-watermark object is other information to be printed, and specifically may be other words except the watermark object to be printed. For example, in an application scenario of printing an express delivery receipt containing a watermark object, the non-watermark object may be, for example, express delivery information to be printed, and the express delivery information may include, for example, a sender name, a sender address, a sender phone, a recipient name, a recipient address, a recipient phone, cargo information, and the like.

When generating an original layer containing a watermark object, defining a single layer for placing characters or patterns exhibiting a watermark effect, and adding the characters or patterns as watermark objects to 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 is provided with a second color characteristic, and the second color characteristic comprises the brightness characteristic of at least one preset primary color. Illustratively, the second color feature is an RGB color feature, which includes luminance features of three primary colors of red, green, and blue.

In operation S220, the initial layer is subjected to a rasterization process, so as to obtain a watermark bitmap layer.

According to the embodiment of the invention, the initial layer is subjected to dot matrix processing to obtain the watermark dot matrix layer containing the watermark object, specifically, at least one pixel point is selected from a preset area containing the watermark object of the initial layer according to a preset rule, and the following operation is performed on 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 according to the first color characteristic of the pixel point, performing chromaticity adjustment processing on the initial chromaticity characteristic of the pixel point, wherein at least one pixel point after the chromaticity adjustment processing forms a watermark lattice layer.

Or determining a first color characteristic of each pixel point in a preset area 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 of an initial layer containing a watermark object according to a preset rule, wherein the pixel point is provided with a first color characteristic, and executing the following operations aiming at the selected pixel point: and according to the first color characteristic of the pixel point, performing chromaticity adjustment processing on the initial chromaticity characteristic of the pixel point, wherein at least one pixel point after the chromaticity adjustment processing forms a watermark lattice layer.

The method for determining the first color characteristic of the pixel point can comprise the following steps: and carrying out color feature conversion processing on the pixel points according to the second color features of the pixel points so as to obtain the first color features of the pixel points. The first color feature may be, for example, an HSB color feature that characterizes color by utilizing three color features of Hue (Hue), saturation (Saturation), brightness (Brightness). Chromaticity (Hue) represents the type of color (e.g., red, green, or yellow) and ranges from 0 to 360, with each chromaticity feature representing a color. Saturation (Saturation) represents the Saturation of a color, the range of values is 0 to 1, saturation is 0 represents a gray scale, and Saturation is 1 represents a pure color. Brightness (Brightness) represents the Brightness of a color, and the range of Brightness is 0 to 1, brightness 0 represents black, and Brightness 1 represents a color of a specific saturation.

The method for obtaining the HSB color characteristic by performing color characteristic conversion processing on the pixel point according to the RGB color characteristic of the pixel point can be realized according to the following conversion relation.

B＝max

Wherein R, G, B represents a red luminance value, a green luminance value, and a blue luminance value, respectively, max represents a maximum luminance value in R, G, B, and min represents a minimum luminance value in R, G, B.

And selecting at least one pixel point from a preset area of the initial layer containing the watermark object according to a preset sparse lattice algorithm, so as to realize the conversion of the initial layer into a sparse lattice layer. Specifically, selecting pixel points with the number of every preset pixel from each pixel point row or each pixel point column in the preset area to obtain at least one pixel point. As an alternative, in the preset area containing the watermark object, according to each pixel line of the preset area, selecting every preset number of pixels from one line end to the other line end line by line. Illustratively, at least one pixel point of every 4 pixels is selected from left to right row by row in each pixel point row from top to bottom in the preset area. As another alternative, in the preset area containing the watermark object, according to each pixel column of the preset area, selecting every preset number of pixels from one column end to the other column end. Illustratively, at least one pixel point of every 4 pixels is selected from top to bottom in each pixel point column from left to right in the preset area. When the pixel point is selected, the preset number of pixels can be one value, or can be a plurality of values, or can be a value adjusted according to the first color characteristic of the pixel point.

The preset area may be any area of the initial layer including the watermark object, specifically may be all areas of the initial layer, or may be a partial area of the initial layer including 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 perform initial chromaticity characteristic adjustment processing. The design is favorable for determining which pixel points are selected for initial chromaticity characteristic adjustment processing according to the determined first color characteristics of the pixel points. Generally, a pixel point with an initial saturation characteristic and an initial brightness characteristic greater than a preset threshold may be selected for initial chroma characteristic adjustment processing. In addition, a part of pixel points can be selected in the 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 beneficial to reducing the workload of color feature conversion processing and improving the efficiency of watermark printing processing by determining the first color features of part of pixel points.

And aiming at the selected at least one pixel point, performing chromaticity adjustment processing on the initial chromaticity characteristics of the pixel point according to the first color characteristics of the pixel point, wherein the at least one pixel point after the chromaticity adjustment processing forms a watermark lattice layer. Specifically, discretization processing can be performed on the initial chromaticity characteristics of each pixel point, so that the initial chromaticity characteristics of each pixel point are converted into target chromaticity characteristics, and the conversion of the initial chromaticity characteristics of each pixel point into chromaticity characteristics with stable printing effect is realized. The watermark printing device is beneficial to realizing stable printing effect and better printing quality when watermark printing is carried out by utilizing different printers, does not need to spend a great deal of time and effort for setting watermark parameters of the different printers, and is beneficial to reducing the implementation cost of watermark printing technology.

When the printer is used for printing characters, the characters in the dot matrix data form are imaged to be in a solid color state, the toner covers all character areas, the influence of the concentration of the toner and the transparency of the image on the character printing effect is not required to be considered, the printing effect is stable, and the printing quality is better. Therefore, the original chromaticity characteristics of the watermark object can be considered to be adjusted, the watermark object is processed into dot matrix data with the same character effect, and when the watermark object in the dot matrix data form is printed by using the printer, the influence of the watermark parameter setting of the printer on the printing effect of the watermark object can be omitted.

In operation S230, the watermark lattice layer is superimposed with other information layers to be printed, to obtain an object to be printed including a watermark object.

According to the embodiment of the invention, when the watermark lattice layer is overlapped with other information layers needing to be printed, the watermark lattice layer can be arranged at the bottom layer, and then the other information layers needing to be printed are overlapped on the watermark lattice layer, so that the object to be printed containing the watermark object is obtained.

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 other information is dot matrix data, the other information layers are dot matrix layers containing non-watermark objects, and the printer can directly obtain the dot matrix data from the dot matrix layers for printing. When other information is PLD data, various printing control instructions in the PLD data can be analyzed, so that the PLD data can be converted into dot matrix data, namely, other information layers are converted into dot matrix layers containing non-watermark objects.

The printing head of the printing equipment can directly print dot matrix data in the dot matrix layer, the printing effect is a character printing effect, and the printing effect does not depend on the transparency of pictures, the model of the printing equipment and the watermark parameter setting of the printing equipment. Therefore, the printing driver of the printing equipment is not required to be set, the watermark parameter of the printing equipment is also not required to be set, and compared with the prior art that a watermark object is processed into a watermark layer, the watermark layer is printed by the printing equipment, the embodiment of the invention has lower implementation cost, more stable watermark printing effect and can realize the printing of the watermark effect even when the printing equipment does not have the watermark printing function.

The technical scheme of the embodiment of the invention provides a processing method capable of realizing watermark printing, which is implemented by generating an initial layer containing a watermark object; performing lattice treatment on the initial layer to obtain a watermark lattice layer; and superposing the watermark lattice layer and other information layers to be printed to obtain the object to be printed containing the watermark object. The method comprises the steps of performing dot matrix processing on an initial layer containing a watermark object to obtain a watermark dot matrix layer containing the watermark object, and then superposing the watermark dot matrix layer with other information layers to obtain an object to be printed containing the watermark object, so that when the object to be printed containing the watermark object is printed, the traditional watermark printing is converted into dot matrix data printing, the printing effect is stable, and the printing quality is excellent; and the watermark printing effect is independent of watermark parameter setting of the printing equipment, so that a great amount of time and effort are not required to be spent on setting the watermark parameter of the printing equipment, and the watermark printing efficiency is effectively improved, and the printing cost of watermark printing is reduced.

Fig. 3 schematically shows a flow chart of another processing method that may enable watermark printing according to an embodiment of the invention.

As shown in fig. 3, the method is applied to a terminal including at least one application program executable. The method may include operations S310 to S330.

In operation S310, an initial layer containing a watermark object is generated.

In accordance with the embodiment of the present invention, the principles and processes of operation S310 may refer to the principles and processes of operation S210, which are not described herein.

In operation S320, according to the first color characteristic of at least one pixel in the initial layer, a chromaticity adjustment process is performed on each pixel, and the at least one pixel after the chromaticity adjustment process forms the watermark lattice 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 characteristic of the pixel point in the initial layer may refer to the principle and the process of operation S220, which are not described herein.

The first color characteristic of the pixel point comprises an initial chroma characteristic, an initial saturation characteristic and an initial brightness characteristic, and specifically comprises an initial chroma value, an initial saturation value and an initial brightness value. When the pixel point is subjected to chromaticity adjustment processing, a preset chromaticity characteristic aiming at the pixel point is determined according to the initial chromaticity characteristic in the first color characteristic of the pixel point, and then a target chromaticity characteristic aiming at the pixel point is determined according to the initial chromaticity characteristic and the preset chromaticity characteristic aiming at the pixel point.

When the preset chromaticity characteristic aiming at the pixel point is determined according to the first color characteristic of the pixel point, the preset chromaticity characteristic is determined to be the first chromaticity characteristic or the second chromaticity characteristic according to the first color characteristic of the pixel point, wherein the first chromaticity characteristic indicates the background color of other information layers, and the second chromaticity characteristic indicates the color of the watermark object. Then, a target chromaticity characteristic for the pixel point is determined according to the initial chromaticity characteristic and the preset chromaticity characteristic for the pixel point. Specifically, determining whether the initial chromaticity characteristic meets a preset condition; if yes, taking the preset chromaticity characteristic as a target chromaticity characteristic; if not, taking the other chromaticity characteristic except the preset chromaticity characteristic as the target chromaticity characteristic in the first chromaticity characteristic and the second chromaticity characteristic.

When determining the preset chromaticity characteristic for the pixel point according to the first color characteristic of the pixel point, the preset chromaticity characteristic can be determined to be the second chromaticity characteristic specifically under the conditions that the difference value between the initial chromaticity characteristic and the first chromaticity characteristic is larger than a first preset value, the initial saturation characteristic is larger than a second preset value and the initial brightness characteristic is larger than a third preset value; the remaining cases determine that the preset chromaticity characteristic is the first chromaticity characteristic.

Since chromaticity represents the type of color, each chromaticity feature represents one color (i.e., each chromaticity value represents one color), when the difference between the initial chromaticity feature of the pixel and the chromaticity feature of the background color of the other information layer is greater than the first preset value, it is indicated that the color of the pixel is different from, or even greater than, the background color of the other information layer. At this time, whether the initial saturation characteristic and the initial brightness characteristic of the pixel point are larger than a preset threshold value 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 both higher, and at this time, the initial color characteristic of the pixel point is converted into a second chromaticity characteristic. When the pixel point subjected to the chromaticity characteristic conversion is the pixel point of the watermark object, the initial color characteristic of the pixel point is not processed; when the pixel is not the pixel of the watermark object, the color of the pixel is set 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, in a case where the initial chroma feature of the pixel point is not the first chroma feature, and the initial saturation feature is greater than the second preset value and the initial brightness feature is greater than the third preset value, determining the preset chroma feature as the second chroma feature. That is, when the color of the pixel is not the background color of the other information layer and the saturation and brightness of the color of the pixel are both high, the color of the pixel is set as the color of the watermark object. And otherwise, determining the preset chromaticity characteristic of the pixel point as a first chromaticity characteristic.

Optionally, the background color of the other information layer indicated by the first chrominance feature is white, and the color of the watermark object indicated by the second chrominance feature is black. At this time, it is first determined whether the color of the pixel is white, and if so, the initial chromaticity characteristic of the pixel 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, and determining whether the initial brightness value of the color of the pixel point is greater than 0.5, and determining that the preset chromaticity characteristic for the pixel point is black when both the initial saturation value and the initial brightness value of the color of the pixel point are greater than 0.5; if the initial saturation value or the initial brightness value of the color of the pixel point is not greater than 0.5, determining that the preset chromaticity characteristic for the pixel point is white.

After the preset chromaticity characteristic for each pixel point is determined, the target chromaticity characteristic for each pixel point is determined continuously according to the initial chromaticity characteristic and the preset chromaticity characteristic of each pixel point. Specifically, according to whether the initial chromaticity characteristic of each pixel point meets a preset condition, determining that the target chromaticity characteristic of each pixel point is a first chromaticity characteristic or a second chromaticity characteristic. That is, after the preset chromaticity characteristic for each pixel point is determined, further adjustment processing is performed on the chromaticity characteristic 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 selection of the preset condition has flexibility and is not uniquely determined.

In the field of printing technology, the colors of printed matter are often expressed using a CMYK print color mode. 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 print depends on reflection of light. The images displayed in the screen are represented by RGB modes, and the images presented in the print are represented by CMYK modes. Before the actual printing, the printed color can be checked by using the reference color, and the printed color can be checked by using a color spectrum which is represented by increasing the chromaticity value of each color by 10% by 10 cells or decreasing the chromaticity value by 10 cells. So, the CMYK values in a general printing technique are multiples of 10, whereby colors that correspond exactly to the CMYK values can be found chromatographically. In the case of relaxing the standard, it is also possible to take the CMYK values as multiples of 5. Therefore, the preset condition in the embodiment of the present invention may be selected to determine whether the initial chromaticity value of the pixel point is a multiple of 5 or 10.

Illustratively, it is determined whether the initial chroma value of the pixel is a multiple of 5, i.e., the initial chroma value of the pixel is left over by 5. When the remainder is 0, taking the preset chromaticity characteristic as a target chromaticity characteristic of the pixel point; if not, taking the other chromaticity characteristic except the preset chromaticity characteristic as the target chromaticity characteristic of the pixel point in the first chromaticity characteristic and the second chromaticity characteristic. Specifically, when the first chromaticity characteristic indicates white and the second chromaticity characteristic indicates black, and 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, determining that the target chromaticity characteristic of the pixel point is black when the preset 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 white.

The method comprises the steps of performing sparse lattice processing on an initial layer containing a watermark object, and performing chromaticity characteristic adjustment processing on pixel points subjected to the sparse lattice processing, so that the initial chromaticity characteristic of each pixel point is converted into a target chromaticity characteristic, specifically, the initial chromaticity characteristic of each pixel point is converted into the chromaticity characteristic of the background color of other information layers, or the chromaticity characteristic of the color of the watermark object. The method comprises the steps of performing dot matrix processing on an initial layer containing a watermark object, processing the watermark object into discrete pixel points, and representing the shape of the watermark object by utilizing the target chromaticity characteristic of each pixel point, so that the watermark object is represented by a group of two-dimensional pixel information.

In operation S330, the watermark lattice layer is superimposed with other information layers to be printed, to obtain an object to be printed including a watermark object.

According to the embodiment of the invention, the watermark lattice layer is obtained by carrying out lattice treatment on the initial layer containing the watermark object, and then the watermark lattice layer is overlapped 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 traditional watermark layer mode of directly printing the watermark object. When an object to be printed is printed, the watermark object in the object to be printed is equivalent to a common printing font, and printing of the watermark object can be realized according to the printing requirement of the common printing font, so that the requirement on printing equipment is effectively reduced, even the printing equipment is not required to have a watermark printing function, the design is favorable for ensuring the stability of the watermark printing effect and improving the watermark printing effect, and the watermark parameter setting of the printing equipment can be performed without spending a great amount of time and effort, so that the watermark printing efficiency is improved, and the watermark printing cost consumption is reduced.
