Detailed Description

At present, the screen layout manufacturing in the printing industry mainly relates to the garment printing industry and the product outer package printing industry.

In the prior art, software used for manufacturing screen printing plate patterns in the garment printing industry mainly has the following problems: one type of software, such as color separation software, needs to extract each color separately and then stratify, and has high requirement on the resolution of pixels; and the trapping on the layer needs manual drawing. Another kind of software, such as CorelDRaw, needs to create a new layer after manual cutout, and the software has an automatic color separation function; but again, the trapping on the layer requires manual drawing.

The screen printing chart making software commonly used in the product outer packaging printing industry can directly carry out color separation on vector diagrams, but can only split colors into C, M, Y and K four primary colors for bitmaps; the background image layer with any scaling can not be automatically generated, if the generation needs to be carried out, the edge of the background image is acquired according to the pattern, and then the edge is drawn (edge expansion) or erased (edge contraction) according to the actual scale. In addition, the software can directly generate all traps for the whole image by setting trap widths at different color overlapping positions, but all the generated traps are stored in a single image layer, and a final screen image can be obtained only by subsequent continuous color separation and screen drawing. The printed network layout of the external package is essentially different from the printed network layout of the garment, so that the network layout required by the garment production cannot be obtained by one key when the software is used for manufacturing the network layout.

The present application provides the following embodiments to solve or partially solve the problems of the above-described aspects. In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In some of the flows described in the specification, claims, and above-described figures of the present application, a number of operations are included that occur in a particular order, which operations may be performed out of order or in parallel as they occur herein. The sequence numbers of the operations, e.g., 101, 102, etc., are merely used to distinguish between the various operations, and the sequence numbers themselves do not represent any order of execution. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor do they limit the types of "first" and "second". In addition, the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Fig. 1 illustrates a flow chart of a screen map generation method according to an embodiment of the present application. The method provided by the embodiment of the application is suitable for a client side or plate making equipment. The client may be hardware integrated on the terminal device and having an embedded program, may also be application software installed in the terminal, and may also be tool software embedded in an operating system of the terminal device, which is not limited in this embodiment of the present application. The terminal equipment can comprise any terminal equipment such as a mobile phone, a tablet personal computer, wearable equipment and AR equipment. The plate-making equipment has the function of automatically generating a screen layout and can produce a corresponding screen plate according to a self-generated screen layout. As shown in fig. 1, the method includes:

101. acquiring an image and production parameters;

102. carrying out color separation processing on an image to obtain at least two color layers, wherein one layer contains partial pixel points in the image;

103. performing trapping processing on part of the at least two color layers to add trapping on the processed color layer;

104. and generating a network layout corresponding to each color layer according to the production parameters, the part of the at least two color layers subjected to the trapping processing and the other part of the at least two color layers not subjected to the trapping processing.

The technical scheme provided by the embodiment can be used for various printing industries, such as the garment printing industry. In the application of the method 101 in the garment printing industry, the production parameters may include, but are not limited to, at least one of a reduction or enlargement size, screen naming information, and the like. In actual printing process, for example the printing form is garment materials, after using the corresponding pattern of screen printing version based on half tone map production to print on garment materials, need carry out high temperature heating drying to this surface fabric, nevertheless because of the problem of surface fabric self material, the surface fabric can lead to the deformation inconsistent because of the shrinkage difference after the heating, and the screen layout just needs to adjust according to actual conditions this moment. Therefore, when the embodiment is implemented, the production parameters may be set in advance, the production parameters may be set after the staff knows the attributes of the printing medium in advance, the execution main body of the embodiment may be automatically generated based on the category to which the printing medium belongs, and the like, and the method is not limited in detail here.

In an implementation solution, the step 101 "acquiring an image and a production parameter" may include:

1011. displaying an interactive interface;

1012. and responding to an input operation triggered by a user through the interactive interface, and acquiring the image and the production parameters input by the user.

In the step 102, the pixels belonging to the same color classification in the image may be clustered based on a clustering algorithm to obtain a color layer corresponding to the color classification. That is, the step 102 "color-separating the image to obtain at least two color layers" may include the following steps:

1021. acquiring pixel information of pixel points in the image;

1022. and clustering the pixels belonging to the same color classification according to the pixel information of the pixels in the image to obtain the at least two color layers.

For example, in specific implementation, the user may input color number information (e.g., lab color number) corresponding to all colors contained in the image through the above-mentioned interactive interface. That is, the step 1012 may specifically be: and responding to an input operation triggered by a user through the interactive interface, and acquiring the image input by the user, color number information corresponding to at least two colors contained in the image and the production parameters.

Wherein, the Lab color number is the Lab value corresponding to a certain color. The Lab color model is based on the perception of color by the human eye, and the Lab value describes all colors that a person with normal vision can see. In the Lab color model, the Lab color model is composed of three elements, i.e., luminance (L) and a and b, related to color. L represents lightness, a represents a red-green color difference, and b represents a blue-yellow color difference. In addition, there is a unique corresponding relationship between the Lab color number and the PANTONE color number used for printing, wherein PANTONE color card (PANTONE) is an international universal standard color card and is commonly called PANTONE in Chinese.

Therefore, in a specific implementation, the step 1022 may be implemented by the following steps:

acquiring color number information corresponding to at least two colors contained in the image;

and based on the color number information corresponding to the at least two colors and the pixel information of the pixel points in the image, performing clustering color separation on the pixel points in the image by using a Lab color space similarity algorithm to obtain at least two color layers.

When the method is specifically implemented, a formula corresponding to the Lab color space similarity algorithm is as follows:

where Δ E represents the color difference, and Δ L, Δ a, and Δ B represent the difference between the two colors in different components, respectively. The color attributes of the pixels can be divided by calculating Δ E values of color number information of each pixel corresponding to each color input by the user. Before the specific implementation, the pixel information of each pixel of the image in this embodiment includes the Lab corresponding to the pixel 1 ₁₁ The value is obtained. Suppose that the image includes 3 colors, and the color number information corresponding to the three colors is: lab ₀₁ 、Lab ₀₂ And Lab ₀₃ . Lab capable of calculating pixel point 1 ₁₁ The values are respectively compared with Lab ₀₁ 、Lab ₀₂ And Lab ₀₃ Corresponding Δ E ₁ 、ΔE ₂ 、ΔE ₃ Taking Δ E ₁ 、ΔE ₂ 、ΔE ₃ The minimum corresponding color number information in the color classification is used as the color classification to which the pixel point 1 belongs.

The premise for the implementation of steps 1021 and 1022 is that the image is a digital image, and the pixel information of each pixel point can be extracted from the image. For the paper design image, a user adopts a picture shot by a camera; or a picture downloaded from a network side, etc., where the picture cannot directly extract the pixel information of each pixel point from the picture. For this reason, the method provided by the embodiment may include:

identifying the image to identify color block areas contained in the image and color number information corresponding to the color block areas;

and generating a color layer corresponding to each color block area based on the identified color block area and the color number information corresponding to each color block area.

In specific implementation, the image may be identified by using an image identification technology, such as a machine learning algorithm (e.g., a neural network model), and not only the color number information corresponding to the colors included in the image but also the outlines of the regions (i.e., color block regions) having the same color are identified.

In the above 103, trapping is also called trapping, which is also called shrinking, and is mainly used to compensate for the trapping between two adjacent different colors caused by inaccurate printing and misregistration. Therefore, it is necessary to add corresponding trapping on some layers to avoid white leakage during printing. Wherein the width of the trapping can be determined based on production parameters, such as the size of the enlarge. In this embodiment, one of the two color layers having a common boundary may be subjected to a trapping process, for example, a color layer having a light color is subjected to a trapping process. And trapping is added in the layer after the trapping treatment. Referring to the example shown in fig. 2, the image 4 is disassembled into two color layers, namely, a color layer 1 and a color layer 2. As can be seen from fig. 2, the color layer 2 is lighter in color than the color layer 1. An outward extension is added to each color layer 2 where there is a common border with the color layer 1 to superimpose the traps 3 on the pattern in the color layer 1 (the trap colors are substantially the same as the color layer 2, but for ease of viewing, the traps are darkened to be highlighted in fig. 2). The shape of the trapping 3 is adapted to the shape corresponding to the boundary region where the trapping is located, and the trapping amount (such as the outward expansion width) is related to production parameters, material characteristics of a printing body, overprinting precision of a printing system and the like.

In the step 104, after obtaining the part of the color layer subjected to the trapping processing in the at least two color layers and the other part of the color layer not subjected to the trapping processing in the at least two color layers, the mesh pattern corresponding to each color may be generated based on the production parameters.

The production parameters in the process of generating the screen map serve to adjust the ratio of each layer, for example, to the size of the layer meeting the actual production requirement. In addition. With the process of generating the corresponding grid map by each color layer, the embodiment is not particularly limited, and the specific implementation process is the same as that in the prior art, which can refer to the related content in the prior art.

According to the technical scheme provided by the embodiment, the image is subjected to color separation processing to obtain the image layers corresponding to different colors, the problem that image color layering can be realized only by manually tracing and matting by using design software in the related technology is solved, and the generation efficiency of the image layers is improved; in addition, the embodiment of the application realizes that the trapping processing is automatically carried out on part of the color layers in at least two color layers, and the trapping is directly superposed in the processed color layers; in addition, the screen layout corresponding to each color layer meeting the production requirements can be automatically generated according to the production parameters, manual adjustment or setting is not needed, the operation is simpler, the generation process of the screen layout is simplified, and the generation efficiency of the screen printing plate is improved.

The specific implementation of step 103 in this embodiment is further described below. That is, in an implementation solution, the step 103 "performing a trapping process on a part of the at least two color layers" in the above step may include:

1031. determining the layer relation of at least two color layers;

1032. according to the layer relation, a first type layer needing to be subjected to trapping and a second type layer needing not to be subjected to trapping are determined from the at least two color layers;

1033. determining a boundary area of the first type of layer needing to be subjected to trapping printing;

1034. and performing trapping processing on the boundary region in the first type of layer according to the trapping size corresponding to the trapping region.

The layer relationship of the at least two color layers may be a relationship in which a common boundary exists and a relationship in which a common boundary does not exist. In specific implementation, the layer relationship between any two color layers can be determined based on a two-dimensional graphics algorithm, and when a common boundary exists between the two color layers, the common boundary area is determined, and the common boundary area is used as a boundary area of one color layer to be subjected to trapping.

The trapping principle is that the foreground color and the background color are mutually overlapped by an internal and external expanding method, so that the phenomenon of white edges between two different colors can be avoided. Generally, when at least two color blocks with larger color difference are connected, trapping is needed. A trap may also be understood as an extended color band. And (3) overlapping and printing the adjacent color layers by adopting a trapping technology of external expansion and internal contraction, namely the size of the color block in one color layer is unchanged, and the size of the color block in the other color layer is changed. Specifically, the size of the outer expansion is enlarged corresponding to the size of the foreground color object, and the size of the background color block is kept unchanged, so that the outer edge of the foreground color block is overprinted on the background color. The inner shrinkage is kept unchanged corresponding to the size of the foreground color block, the hollow part of the background color block is shrunk, and the foreground color block is overprinted on the edge of the shrunk background color block hollow part. Generally, in the trapping process, whether the inner contraction or the outer expansion is adopted depends on the contrast of the foreground color and the background color, and generally, the following principle is followed in the outer expansion: the background color is not expanded, the light color is expanded, the dark color is not expanded, and the flat net is expanded without being expanded. The reason is that the background color, light color and plain net have less visual impact on people than the foreground color, dark color. Otherwise, one can easily perceive the change in the shape of the object.

In an implementation solution, the trap between two layers of different colors can be fixed in one of the color layers, for example, the trap between two layers of different colors can be fixed in a light color layer. That is, in step 1032, "determining a first type of layer that needs to be subjected to trapping and a second type of layer that does not need to be subjected to trapping from the at least two color layers according to the layer relationship," may specifically be:

10321. according to the layer relation, two target layers with a common boundary are found out from the at least two color layers;

10322. and determining a target image layer with light color as a first type of image layer needing to be subjected to trapping compensation, and determining a target image layer with dark color as a second type of image layer needing not to be subjected to trapping compensation.

More specifically, step 10322 may include the steps of:

obtaining the brightness values corresponding to the two target layers respectively;

determining a target layer with a large brightness value as a first layer to be subjected to trapping compensation;

and determining the target layer with small brightness value as a second type layer without the need of the supplemental trapping.

In practical application, after the two color layers are overprinted by trapping, sometimes an additional line that does not exist in the pattern is generated, and for this reason, the following steps are added in this embodiment:

105. obtaining the first type of layer after the trapping processing;

106. and smoothing the supplementary trapping in the first type of layer.

In this embodiment, the step of smoothing the trapping is to generate a gradient effect of the color of the trapping so as to weaken lines caused by the overprinting. In specific implementation, the color of the trapping can be smoothed by using a corresponding image processing method, wherein the smoothing process is not specifically limited in this embodiment, and may be implemented by referring to related contents in the prior art.

Since the color layer is split in the embodiment by means of pixel color clustering, the obtained color layer may have an edge mosaic as shown in fig. 2. In most cases, the designer designed the design has smooth edges, except for some designs that are specifically designed for a mosaic effect. Therefore, the present embodiment further adds the following steps:

107. performing edge mosaic processing on the at least two color layers to obtain the at least two color layers with smooth edges, and executing the trapping processing step and the screen printing plate image generating step based on the at least two color layers with smooth edges.

This step 107 may precede

steps

103 and 104 so that the color layers participating in

steps

103 and 104 are both color layers having smooth edges after edge mosaic processing. In specific implementation, the edge mosaic problem existing after bitmap color separation can be improved based on two-dimensional graphics and image processing. Similarly, the specific implementation of the edge mosaic processing in this embodiment is not limited, and all schemes that can perform the edge mosaic processing in the prior art can be applied to this embodiment.

Further, the technical solution provided by the embodiment of the present application further includes:

108. generating a bottoming layer according to the image;

109. and determining a screen printing plate corresponding to the priming image layer based on the priming image layer and the production parameters.

In the above 108, "generating a priming image layer according to an image" may specifically include the following steps:

1081. acquiring outline information of a pattern in an image;

1082. adjusting the outline information according to the production parameters to obtain a bottoming layer

In 1081, the outline information of the pattern in the image can be obtained by using an image recognition technology, wherein the outline information at least includes the size and shape of the image.

In 1082, the height and width of the profile information is adjusted based on the production parameters entered by the user. In particular, the profile information is adjusted according to the size of the reduction or enlargement in the production parameters.

In 109, after the underlying layer is obtained, the mesh pattern corresponding to the underlying layer is generated. In one case, the underlying layer is directly used as the mesh map.

In the actual production process, information, such as header information, footer information, screen positioning symbols, and the like, needs to be noted on each screen icon. The marking information needs to be generated on the screen printing plate corresponding to each screen printing plate; the screen plate is used in the printing process. The worker can determine the number of the screen printing plates, the image names and the like corresponding to the printing images at this time through the marking information on the screen printing plates; the printing equipment can also carry out positioning operation and the like through screen positioning symbols on the screen printing plate. Namely, the present embodiment further includes the steps of:

110. determining the margin of the net layout corresponding to the bottoming layer;

111. acquiring screen plate naming information;

112. and determining a header for the screen image corresponding to the priming image layer based on the screen naming information.

In the above step 110, the margin of the mesh map corresponding to the underlying layer may be determined based on two-dimensional graphics and image processing in the prior art. The margins may include margins in four directions, that is, the distance between the upper boundary and the lower boundary, the distance between the left boundary and the right boundary of the pattern in the halftone screen image.

In the above 111, the screen naming information may be included in the production parameters input by the user. The user can input by himself through the interactive interface. Screen naming information may include, but is not limited to: the type of the clothes, the serial number of the clothes, the printing position, the color of the layer corresponding to the screen image and the like.

Besides, headers are noted for the screen icons corresponding to the underlying image layers, headers are also noted for the screen icons corresponding to the at least two color image layers. Meanwhile, the page feet can be also filled in the screen image corresponding to the bottoming image layer and the screen image icons corresponding to the at least two color image layers. That is, the technical solution provided in the embodiment of the present application further includes:

113. determining page headers for the screen images corresponding to the at least two color image layers respectively according to the screen naming information;

114. and marking page pins for the screen pattern corresponding to the at least two color layers and the screen icon corresponding to the priming layer.

Wherein, the page headers of the screen printing plate corresponding to each color layer can be the same as the page headers of the screen printing plate corresponding to the bottoming layer. For the footer, the process sequence of the screen printing plate corresponding to each screen image in the printing process can be determined, for example, when printing, the bottom color of the pattern needs to be printed by using the screen printing plate of the screen image corresponding to the priming image layer, and then, the printing is performed on the bottom color by using the screen printing plate of the screen image corresponding to each color image layer. Therefore, the footer of the mesh map corresponding to the bottoming layer can be marked as 1, and the footers of the mesh map corresponding to the rest color layers are arranged from 2 to the back according to the printing process sequence. Specifically, the footers of the halftone graph can adopt a similar form, such as 2/10: the total number of the images corresponding to the mesh pattern is 10, and the current mesh pattern is the second one.

After the headers and the footers are arranged, the screen printing plate corresponding to the screen printing plate can be positioned. However, the headers and the footers are characters, and deviation is easy to occur in the actual positioning process, so that screen positioning symbols can be marked on the screen image. That is, the technical solution provided in the embodiment of the present application further includes:

115. and according to the header and the footer of the screen layout, respectively marking screen positioning symbols for the screen layout corresponding to the bottoming layer and the screen icons corresponding to the at least two color layers.

The screen positioning symbol can be used for mounting a screen plate corresponding to the screen pattern. Referring to FIG. 3, a screen illustration 5 of a primed image layer having a header 6, footer 7, and screen alignment symbology
