It is noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of the present application and in the foregoing figures, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
Example 1
Fig. 1 is a flowchart of an inkjet printing method for a printed circuit board according to an embodiment of the present application, where the method may be performed by an inkjet printing apparatus for a printed circuit board, and the apparatus may be implemented in hardware and/or software. As shown in fig. 1, the method includes:
step S101, an original vector diagram to be printed is obtained, and the type of the original vector diagram is identified and determined.
Specifically, in this embodiment, after the original vector image is obtained, the type of the original vector image is identified, and when it is determined that the original vector image includes a specified element, for example, a closed shape, the closed shape is extremely easy to undergo ink fusion when performing subsequent printing, so that the interiors of the closed shapes are all fused, and the recognition of the printing result is difficult.
Optionally, identifying the original vector image to determine the type of the original vector image includes: obtaining a vector diagram type list, wherein the vector diagram type list comprises the corresponding relation between a vector diagram and a type; inquiring from the vector diagram type list according to the original vector diagram to obtain the type corresponding to the original vector diagram; the queried type is taken as the type of the original vector diagram.
Optionally, before identifying the original vector diagram and determining the type of the original vector diagram, the method further includes: obtaining sample data, wherein the sample data comprises a corresponding relation between a vector diagram and a type; training through sample data to obtain a type identification model; identifying the original vector diagram to determine the type of the original vector diagram comprises the following steps: inputting the original vector diagram into a type recognition model; and identifying the original vector diagram through a type identification model, and determining the type of the original vector diagram according to the identification result.
The types of the original vector diagrams comprise characters or symbols, and various modes can be adopted when the types of the original vector diagrams are identified, wherein the first mode is to acquire the types of the original vector diagrams by querying a vector diagram type list; the second way is to identify the type of the original vector image by a pre-trained type identification model, and the specific way of obtaining the type of the original vector image is not limited in this embodiment.
In a specific implementation, when the type of the original vector diagram is acquired by adopting a mode of inquiring the vector diagram type list, particularly, the vector diagram type list is acquired, and the corresponding relation between the vector diagram and the type is contained in the vector diagram type list, so that after the original vector diagram is acquired, the type of the original vector diagram can be quickly acquired through inquiring the vector diagram type list, each vector diagram with relatively high printing times is contained in the vector diagram type list, and the types of each vector diagram particularly comprise two types of characters or symbols. Table 1 below is an example of a table of acquired vector diagram type classes:
TABLE 1
However, table 1 is merely an example, and the specific contents of the vector diagram included in table 1 are not limited in this embodiment.
In another specific implementation, in this embodiment, the training of the model may be performed by using sample data marked with a correspondence between the vector image and the type, and the type recognition model may be obtained through training, where a BP neural network algorithm may be used in performing the training, and the type of the obtained type recognition model may be specifically a BP neural network model. Therefore, after the type recognition model is obtained through training, the original vector diagram can be recognized through the type recognition model, so that the type of the original vector diagram can be quickly obtained. For example, when the original vector diagram "4" is input into the type recognition model, the type of the original vector diagram can be quickly obtained to be text.
In step S102, when it is determined that the specified element is included in the original vector diagram, primitive reduction processing is performed on the original vector diagram according to the type to acquire an adjustment vector diagram.
Optionally, performing primitive reduction processing on the original vector diagram according to the type to obtain an adjustment vector diagram, including: when the type is determined to be a text, acquiring the current font of the original vector diagram; acquiring a target font simplified than the current font from a font library, and carrying out font replacement on an original vector image according to the target font to acquire an updated vector image; and determining an adjustment vector diagram according to the updated vector diagram.
Optionally, determining the adjustment vector diagram according to the updated vector diagram includes: judging whether the updated vector diagram further comprises a closed shape, if so, adjusting the closed shape in the updated vector diagram into an open shape to obtain an adjusted vector diagram, otherwise, directly taking the updated vector diagram as the adjusted vector diagram.
Specifically, in this embodiment, after the original vector diagram is obtained, the original vector diagram is checked to determine whether a specified element, such as a closed shape, is included in the original vector diagram. When it is determined that the closed shape is included in the original vector image, primitive reduction processing is performed on the original vector image according to the type to acquire an adjustment vector image. When the type of the original vector diagram is determined to be text, for example, when the original vector diagram is "4", since a closed triangle exists and the type is text, the current font of the original vector diagram is acquired, and a target font simplified than the current font is acquired from a font library, for example, the updated vector diagram is acquired by changing the font of the original vector diagram according to the acquired target font, thus, the updated vector diagram can be obtained, the upper vertex angle of the closed triangle in the updated vector diagram is opened, and thus the closed triangle is converted into an open shape, and in this case, the updated vector diagram is directly used as an adjustment vector diagram. It can be seen that the adjustment vector image has a reduced number of primitives for the region to be printed relative to the original vector image, and thus the primitive density for the region to be printed has also been reduced. In addition, for the original vector diagram of the text type, there may be a case that the closed shape cannot be canceled even if the font is changed, in which case it is necessary to newly adjust the closed shape in the updated vector diagram to the open shape to obtain the adjusted vector diagram. From the above, it can be known that, for the original vector diagram of the text type, since the font changing mode is simpler and more convenient, the font changing can be performed first, and when the closed shape is cancelled indirectly by the font changing mode, the subsequent adjustment of the closed shape is not needed, thereby improving the adjustment efficiency.
Optionally, performing primitive reduction processing on the original vector diagram according to the type to obtain an adjustment vector diagram, including: when the type is determined to be a symbol, directly adjusting the closed shape in the original vector diagram to be an open shape; and obtaining an adjustment vector diagram according to the adjustment result.
Optionally, directly adjusting the closed shape in the original vector diagram to an open shape includes: determining an open position for the closed shape in the original vector diagram; the closed shape is opened in the open position to adjust the closed shape to the open shape.
When the type of the original vector diagram is determined to be a symbol, the symbol has no concept of font relative to the text, so that the change of the closed shape cannot be realized by a font changing mode, and therefore, an open position needs to be determined on the closed shape, and the closed shape is opened at the open position so as to be adjusted to the open shape. The principle of the open position selection is that the basic meaning of the original vector diagram is not affected when the open position is opened, for example, when the original vector diagram is formed by two adjacent closed shapes, the connection place of the two closed shapes cannot be used as the open position because if the open position is opened, the meaning of the original vector diagram is completely changed. Of course, the present embodiment is merely an example, and the user may set the selection mode of the opening position in advance according to the actual requirement, and the present embodiment is not limited thereto.
Step S103, converting the adjustment vector diagram into a bitmap, and performing inkjet printing of the printed circuit board according to the bitmap.
Specifically, in this embodiment, after the adjustment vector image is obtained, since the density of the pixels in the area to be printed in the adjustment vector image is reduced, after the adjustment vector image is converted into the bitmap, the density of the pixels in the area to be printed in the bitmap is also reduced correspondingly, so when the inkjet printing of the printed circuit board is performed according to the converted bitmap, the density of the pixels in the area to be printed is reduced, the intensity of ink fusion can be effectively reduced, the printing effect of the image is improved, the identifiability of the printing result is obviously enhanced, and the situation that "0" is printed to "1" is avoided. When converting the vector image into the bitmap, a plurality of conversion modes may be adopted, and the embodiment is not limited to a specific conversion mode, and the conversion process from the vector image to the bitmap is not an important point of the present application, so that a detailed description is not provided in the embodiment.
According to the embodiment of the application, when the original vector image is determined to comprise the closed shape, the original vector image is subjected to the primitive reduction processing to obtain the adjustment vector image and then is converted into the bitmap, and the pixels to be printed in the corresponding bitmap are reduced under the condition of primitive reduction, so that the interference of the ink-jet printing characteristics such as ink fusion on the printing result is reduced, and the recognition of the printing result is improved.
Example two
Fig. 2 is a flowchart of an inkjet printing method for a printed circuit board according to a second embodiment of the present application, where the embodiment is based on the above embodiment, and after performing inkjet printing on the printed circuit board according to a bitmap, the method further includes: and detecting the ink jet printing result of the printed circuit board. The same terms as those of the above embodiments are not repeated herein. As shown in fig. 2, the method includes:
step S201, an original vector diagram to be printed is obtained, and the type of the original vector diagram is identified and determined.
Optionally, identifying the original vector image to determine the type of the original vector image includes: obtaining a vector diagram type list, wherein the vector diagram type list comprises the corresponding relation between a vector diagram and a type; inquiring from the vector diagram type list according to the original vector diagram to obtain the type corresponding to the original vector diagram; the queried type is taken as the type of the original vector diagram.
Optionally, before identifying the original vector diagram and determining the type of the original vector diagram, the method further includes: obtaining sample data, wherein the sample data comprises a corresponding relation between a vector diagram and a type; training through sample data to obtain a type identification model; identifying the original vector diagram to determine the type of the original vector diagram comprises the following steps: inputting the original vector diagram into a type recognition model; and identifying the original vector diagram through a type identification model, and determining the type of the original vector diagram according to the identification result.
In step S202, when it is determined that the specified element is included in the original vector diagram, primitive reduction processing is performed on the original vector diagram according to the type to acquire an adjustment vector diagram.
Optionally, performing primitive reduction processing on the original vector diagram according to the type to obtain an adjustment vector diagram, including: when the type is determined to be a text, acquiring the current font of the original vector diagram; acquiring a target font simplified than the current font from a font library, and carrying out font replacement on an original vector image according to the target font to acquire an updated vector image; and determining an adjustment vector diagram according to the updated vector diagram.
Optionally, determining the adjustment vector diagram according to the updated vector diagram includes: judging whether the updated vector diagram further comprises a closed shape, if so, adjusting the closed shape in the updated vector diagram into an open shape to obtain an adjusted vector diagram, otherwise, directly taking the updated vector diagram as the adjusted vector diagram.
Optionally, performing primitive reduction processing on the original vector diagram according to the type to obtain an adjustment vector diagram, including: when the type is determined to be a symbol, directly adjusting the closed shape in the original vector diagram to be an open shape; and obtaining an adjustment vector diagram according to the adjustment result.
Optionally, directly adjusting the closed shape in the original vector diagram to an open shape includes: determining an open position for the closed shape in the original vector diagram; the closed shape is opened in the open position to adjust the closed shape to the open shape.
Step S203, converting the adjustment vector diagram into a bitmap, and performing inkjet printing of the printed circuit board according to the bitmap.
In step S204, the inkjet printing result of the printed circuit board is detected.
In this embodiment, after the inkjet printing of the printed circuit board is performed according to the bitmap, the inkjet printing result is detected, and the specific detection mode may be to score the printing result by an image recognition mode, where the clearer the inkjet printing result, the higher the corresponding score. In this embodiment, an alarm score is preset, and when it is determined that the score corresponding to the result of inkjet printing is smaller than the alarm score, it is indicated that the effect of inkjet printing on the current bitmap is extremely poor, and it is difficult for the user to perform effective recognition. The reasons for the above may be that the process of adjusting the vector image is wrong, or that the manner of converting the vector image into a bitmap is wrong, or that the printing apparatus is malfunctioning, and the reasons for the above result are not limited in this embodiment.
When the score corresponding to the ink-jet printing result is smaller than the early warning score, alarm information is generated and displayed for the user to check, so that the user can conveniently and timely maintain equipment or software according to the alarm information, and the accuracy of the ink-jet printing result is further improved.
According to the embodiment of the application, when the original vector image is determined to comprise the closed shape, the original vector image is subjected to the primitive reduction processing to obtain the adjustment vector image and then is converted into the bitmap, and the pixels to be printed in the corresponding bitmap are reduced under the condition of primitive reduction, so that the interference of the ink-jet printing characteristics such as ink fusion on the printing result is reduced, and the recognition of the printing result is improved.
