Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a schematic flow chart of a method for processing jet printing data of a multi-nozzle jet printing apparatus according to an embodiment of the present invention, and the method for processing jet printing data of the multi-nozzle jet printing apparatus according to the embodiment of the present invention includes the following steps:
As one embodiment, the information of the material to be jet-printed includes object information, source information and attribute information of the material.
As an embodiment, as shown in fig. 2, information of the to-be-jet-printed material edited by the user is extracted from the database to obtain information of the to-be-jet-printed material corresponding to the multi-nozzle jet printing apparatus.
That is, the information of the material to be jet printed edited by the user is extracted from the database, wherein the information comprises material attribute information, object information contained in the material, source information and material layout contained in the material, style information, object layout and style information.
As an embodiment, processing the information of the material to be jet printed to convert the information into corresponding bitmap data, including creating a corresponding object entity according to the information of the material to be jet printed; the corresponding object entities are converted into corresponding bitmap data.
That is, as shown in fig. 3, a corresponding object entity is created according to the acquired information of the material to be jet printed; and converting into corresponding bitmap data according to the object attribute and the source attribute edited by the user so as to perform source format conversion and object bitmap conversion.
Namely, a corresponding object entity is created according to the object information; and creating a corresponding source entity according to the source information, and converting the source format data associated with the object into corresponding bitmap data according to the association parameters according to the source format data and the object parameters (object coordinates, object typesetting parameters such as word spacing, font style, bold, oblique, line drawing and the like, object effect parameters such as rotation, mirror image, edge drawing and the like).
And 103, coding the bitmap data according to preset jet printing configuration information to obtain data to be transmitted corresponding to the multi-nozzle jet printing equipment.
As an example, the preset jet printing configuration information includes a jet printing combination relationship, a jet printing mode, a jet printing direction, an offset between jets, an overlap dot number, a print DPI, and a combination mirror image.
It should be noted that the combination relationship of the nozzles is the number of nozzles that need to operate in the combined jet printing and the combination manner thereof, such as P1P2P3P4 combination, P1P3 or P2P4 combination, where P1 represents the first nozzle, P2 represents the second nozzle, P3 represents the third nozzle, and P4 represents the fourth nozzle.
That is to say, the combination can be carried out at will according to actual needs, the number of the physical spray heads is not limited, the combination mode is not limited, and a plurality of code spraying devices can be cascaded and expanded.
It should be noted that the spray printing mode includes left spray (spray printing with left row nozzles of the nozzle), right spray (spray printing with right row nozzles of the nozzle), alternate spray (spray printing with left and right nozzles of the nozzle in turn), double spray (spray printing with left and right nozzles of the nozzle simultaneously) or over spray (spray printing with left and right nozzles of the nozzle simultaneously, only extracting data, reducing addressing, achieving the purpose of quick spray printing), etc.
In addition, the preset jet printing configuration information can also comprise the distance between the left nozzle and the right nozzle and the coupling coefficient of the spray head according to actual needs.
As a specific example, as shown in fig. 4 to 5, encoding bitmap data according to preset print configuration information to obtain data to be transmitted corresponding to a multi-nozzle print device includes: judging whether the bitmap data is legal or not according to preset jet printing configuration information, and cutting the bitmap data to obtain cutting coordinate information when the bitmap data is judged to be legal; and acquiring compression associated parameters according to preset spray printing configuration information so as to encode the bitmap data according to the cutting coordinate information and the compression associated parameters to obtain data to be transmitted corresponding to the multi-nozzle spray printing equipment.
It should be noted that, by determining whether the XY coordinates, W width, and H height of the bitmap data are valid, determining whether the bitmap data are in the mapping space, and the like, if so, determining that the bitmap data are valid.
It should be noted that the cutting coordinate information may be obtained by performing a horizontal cutting or a vertical cutting on each bitmap data and saving the cutting coordinate information, for example, recording the starting point (x, y) of each row of the bitmap.
The method for acquiring the compression associated parameters according to the preset jet printing configuration information so as to encode the bitmap data according to the cutting coordinate information and the compression associated parameters to obtain the to-be-transmitted data corresponding to the multi-nozzle jet printing equipment comprises the following steps of: acquiring coordinate information of bitmap data in a compressed cache, block information of bitmap data divided to a spray head and determining a coding model according to preset spray printing configuration information; acquiring a corresponding coding step according to the coding model; and mapping the bitmap data to a compression cache according to the cutting coordinate information, the coordinate information of the bitmap data in the compression cache, the coding model and the coding step length so as to carry out coding processing, so as to obtain the data to be transmitted corresponding to the multi-nozzle jet printing equipment.
It should be noted that the information such as the coordinate information of the cutting coordinate information and the bitmap data in the compression cache, the coding model, the coding step length and the like is obtained before the coding compression, so that the compression associated parameters are determined, the reacquisition before each coding is avoided, and the calculation overhead is saved.
That is, before encoding and compressing, bitmap line division calculation (recording the starting point of each line of the bitmap), coordinate information of the bitmap in a compression cache and block information of the bitmap divided to a spray head are calculated according to configuration parameters such as combination configuration (P1.. PN, horizontal dpi, printing mode, printing direction, combination mirror image and the like) and printing configuration (combination horizontal offset, vertical offset, spacing, printing direction and the like), an encoding model (odd spray, even spray.. Super spray, horizontal mirror image, vertical mirror image) is determined according to the configuration parameters, an appropriate encoding step length (after the bitmap with multiple lengths is encoded once, switching is carried out to the next channel encoding to achieve balanced encoding) is calculated according to the current printing data and the encoding model, recalculation before each encoding is avoided, and calculation overhead is omitted.
Specifically, first, the bitmap mapping calculation of the object (judging whether the XY coordinate, W width, and H height of bitmap data are legal or not in the mapping space, calculating initial nozzle information, calculating mapping initial coordinates, and the like); then, cutting the bitmap data to obtain cutting coordinate information (each object bitmap data can be transversely cut to obtain cutting coordinate information, and the starting point (x, y) of each row of the bitmap is recorded); next, bitmap segmentation information and coordinate information of a nozzle compressed data buffer area are calculated, and the coordinate information of the bitmap allocated to the nozzles and corresponding line height information are calculated according to parameters such as combination configuration (p 1.. PN, horizontal dpi, combination mirror image and the like) and printing configuration (combination horizontal offset, vertical overlapping points) and the like, wherein due to the use of a virtual canvas, an object bitmap is allocated to the nozzles to be divided into a starting section, a middle section and a tail section in consideration of 8-bit alignment, and simultaneously, the bitmap is mapped to a compressed data buffer area to be sent of an actual nozzle and is also divided into the starting section, the middle section and the tail section, and a specific segmentation model is shown in fig. 5; then, determining relevant parameters of coding processing, and determining a coding processing inlet according to configuration parameters (odd-spraying, even-spraying, double-spraying, super-spraying, horizontal mirror image, vertical mirror image and vertical DPI.); calculating a proper coding step length (after a bitmap with multiple lengths is coded at one time, switching to the next channel coding to achieve balanced coding) according to the current printing data; and finally, encoding bitmap data to a nozzle compressed data buffer area, and performing actual encoding compression mapping calculation according to the information obtained in the previous step.
In addition, according to the jet printing data processing method of the multi-nozzle jet printing equipment, the virtual canvas is used for carrying out data bitmap conversion, the whole canvas is not distributed, only the object bitmap contained in the data is divided, and the object bitmap is directly converted into the mapping space corresponding to the nozzles, so that the memory space is reduced as much as possible; only the bitmap data belonging to the spray printing range of the spray head is subjected to cutting mapping calculation, and the bitmap data exceeding the range is directly filtered; in the same process, the model completes the functions of cutting, distributing, mirroring, inverting, converting the size end, compressing and coding (adapting to different spray printing modes, such as odd spray, even spray, odd-even alternation, over spray and the like), printing direction adaptation, balanced coding and the like of a bitmap object, avoids unnecessary repeated traversal calculation caused by a separation process (such as inverting the bitmap, then mirroring, then splitting and the like), and greatly saves the calculation time of a CPU; because the length of the bitmap of the data containing objects is different, the nozzles are divided into groups, and if the data is coded synchronously (after one group of data is coded by one combined channel and then the data of the next combined channel is coded), the printing is incomplete under high-speed printing; therefore, bitmap data of different channels (nozzles) are compressed and coded in turn, and balanced coding conversion is achieved no matter at low speed or high speed by adjusting the coding step length of the alternate stream, so that discontinuous transmission caused by uneven coding time is prevented; because the lengths of the printed data of different channels are different, if the data are transmitted synchronously (after one data of one combined channel is transmitted, the data of the next combined channel is transmitted), the printing is incomplete under the high-speed printing; therefore, data of different channels (nozzles) are transmitted in turn, and the balanced transmission is realized no matter at low speed or high speed by adjusting the transmission step length of the wheel stream, so that the transmission is prevented from being interrupted.
In addition, the spray printing data processing method of the multi-nozzle spray printing equipment further comprises the step of storing the data to be transmitted corresponding to the multi-nozzle spray printing equipment to a transmission queue so as to obtain the data to be transmitted from the transmission queue and transmitting the data to be transmitted to the multi-nozzle spray printing equipment for spray printing.
In summary, according to the method for processing the jet printing data of the multi-nozzle jet printing device in the embodiment of the invention, the information of the data to be jet printed corresponding to the multi-nozzle jet printing device is obtained first; then processing the information of the data to be jet-printed to convert the information into corresponding bitmap data; finally, coding the bitmap data according to preset spray printing configuration information to obtain data to be transmitted corresponding to the multi-nozzle spray printing equipment; therefore, the multi-head random combination and random expansion can be realized under the condition of low computational power, the high-speed jet printing can be realized, and the jet printing efficiency is greatly improved.
In addition, an embodiment of the present invention further provides a computer-readable storage medium, on which a print data processing program of a multi-nozzle print apparatus is stored, where the print data processing program of the multi-nozzle print apparatus is executed by a processor to implement the print data processing method of the multi-nozzle print apparatus.
According to the computer-readable storage medium of the embodiment of the invention, the jet printing data processing program of the multi-nozzle jet printing equipment is stored, so that the processor can realize the jet printing data processing method of the multi-nozzle jet printing equipment when executing the jet printing data processing program of the multi-nozzle jet printing equipment, thus realizing the arbitrary combination and arbitrary expansion of multiple heads under the condition of low calculation power, realizing high-speed jet printing and greatly improving the jet printing efficiency.
In addition, a third embodiment of the present invention provides a computer device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the processor executes the computer program, the processor implements the method for processing the inkjet data of the multi-nozzle inkjet printing device.
