When one-time printing is needed, the printing module, the physical channel and the logic channel are configured, the logic channel is used as a bridge for extracting data during printing, the logic channel is used as the bridge for extracting data, the physical channel corresponding to each logic channel is determined to be the largest according to the serial number of the logic channel, the logic channel parameter and the serial number of the current printing task of each logic channel are determined, one printing task can be printed when a common primary machine is started for printing a plurality of printing tasks, for example, 300 parts of variable images need to be printed, each time of printing has a same background image and a variable image at the same position of the background image, each part is a printing task, and each printing task has identity information, namely the serial number of the printing task in the invention, and each printing module of the printing tasks is provided with a task queue, and task statistics is carried out when each task is printed, so that the serial number of the current printing task can be obtained when the printing data is extracted by the logic channel. The physical channel is a data volume corresponding to one spray head in one-time ignition printing, or a data volume of one color in the spray head, or a data volume of a row of spray holes. If the physical channels are data volumes corresponding to one nozzle, each physical channel only belongs to one production line according to printing requirements, and each physical channel is configured with one logical channel, so that the logical channels and the physical channels are in one-to-one mapping relation.

s3, obtaining the storage address and the printing parameter of the channel data corresponding to the logic channel according to the logic channel parameter, the task parameter corresponding to the current printing task and the printing position;
s4, extracting the channel data from the printing memory according to the storage address, and processing the channel data and the printing parameters to obtain printing data.
Referring to fig. 2, specifically, in a certain printing, it is required to first obtain a logic channel number, and obtain a logic channel parameter corresponding to the logic channel number and a current print task number of the logic channel while obtaining the logic channel number; the method comprises the steps of simultaneously obtaining task parameters and a printing position of a task according to a current printing task number, then obtaining a storage address and a printing parameter of channel data corresponding to a logical channel in a printing memory through logic channel parameters, the task parameters corresponding to the current printing task and the printing position, correctly extracting the channel data from the printing memory according to the storage address, carrying out data processing on the channel data according to the printing parameter to obtain printing data, and then accurately inputting the printing data into a physical channel according to a mapping relation between the logical channel and the physical channel to carry out ink jet printing.
The task parameters include the printing size of a printing target image corresponding to a current printing task, the number of physical channels and the position of the physical channels which are required to be used in the printing process are determined according to the size of each printing target image, then the logical channels are configured for the printing task according to the number of the physical channels, and the logical channel parameters such as the relative position between each logical channel are determined according to the position of the physical channels, so that the logical channel parameters include channel offset, channel enable and channel insertion points, the channel offset is used for judging whether the corresponding channel works in the current printing task, the channel insertion points are specifically used for calculating the storage address of the corresponding data in the memory, that is, the data address of the channel corresponding to the logical channel of a certain printing task is: the number of the channel plug points is x, the data length corresponding to the logic channel and the initial data address of the current printing line. And the printing position comprises a coordinate value of the current printing task in a first direction relative to the printing platform and a current printing coordinate value in a second direction perpendicular to the first direction, and when all the logic channels finish one-time data reading, the current printing coordinate value of the current printing task is added with 1. Specifically, referring to fig. 3, the printing size of the printing target image F in the current task parameter is the length of two nozzles along the nozzle arrangement direction (x direction), in this example, a nozzle is defined that can print 300 pixels (that is, the number of nozzles owned by a nozzle is 300), the length of a nozzle along the direction perpendicular to the nozzle arrangement direction (y direction), and the specific printing position is the position from the 3 rd nozzle to the 4 th nozzle. Taking an example that one physical channel corresponds to one nozzle, when each physical channel is configured with one logical channel, the channel offset of the logical channel PCH0 in the x-axis direction is 0 distance of the nozzles, that is, no offset, the channel offset of the logical channel PCH1 in the x-axis direction is 1 distance of the nozzles, that is, 300 pixels, the channel offset of the logical channel PCH2 in the x-axis direction is 2 distances of the nozzles, that is, 600 pixels, and so on, the channel offset of each logical channel in the x-axis direction is obtained. The print image is processed by the image raster processor and is arranged according to original data, namely 720 pixel points are required to be printed on each inch of each row of the 720 × 720DPI image, but the actual spray head only has 360 nozzles, namely 360 pixels are printed at most once, and 720 pixels are required to be printed twice, so that the data is required to be split, in order to ensure that the 720 pixel points are evenly printed on the data and are staggered into two parts and are subjected to interpolation numbering, namely each part has one interpolation point, when the logical channel is used for data extraction, the channel interpolation point number of the logical channel is required to be changed, namely the logical channel is required to extract the channel data to accurately calculate the address of data storage. The printing position is an accurate coordinate value of a target image printed specifically relative to the printing platform, so that the printing device knows the specific printing position of the target image clearly, as shown in fig. 3, the coordinate value of a current print job in the printing position relative to the printing platform in a first direction (X direction) is 600 pixels, the range of the current print coordinate value in a second direction (Y direction) perpendicular to the first direction is 300 pixels to 600 pixels, when all logic channels finish one data reading, the current print coordinate value of the current print job is added by 1, the current print coordinate value is a value of a Y-axis accumulator of the printing device, the Y-axis accumulator is connected with a raster in the Y direction of the printing device, and a specific position count is obtained according to the raster.
Referring to fig. 4, in the step S3: after the storage address and the printing parameter of the channel data corresponding to the logical channel are obtained according to the logical channel parameter, the task parameter corresponding to the current printing task and the printing position, the method further comprises the following steps:
s31, determining the printing range of the printing target image in the second direction according to the printing size and the printing position of the target image;
s32, judging whether the channel offset is in the printing range according to the current printing coordinate value of the current printing task;
s33, when the channel offset is within the printing range, the channel data is valid;
and S34, when the channel offset is not in the printing range, the channel data is invalid.
Specifically, as shown in fig. 3, an xy two-dimensional coordinate system is established with the direction in which the nozzles are arranged as the x-axis, the direction in which the printing medium moves as the y-axis, the length of one nozzle is 300 pixels, the printing size of the print target image F in the current job parameter is 600 pixels, which are the lengths of two nozzles, 300 pixels, which are the lengths of two nozzles, in the direction perpendicular to the nozzle arrangement direction, the specific printing position is 600 → 1200, which is the position from the 3 rd nozzle to the 4 th nozzle, which is the coordinate in the x-axis direction, the printing range of the print target image F is 600 → 1200, the y-axis direction is 300 → 600, whether the logical channel is located in the printing range is determined according to the current printing coordinate value of the current printing job, and when the current printing coordinate value is within the 300 → 600 range, the logical channel is within the printing range, the channel data is valid; when the current print coordinate value is not within the range of 300 → 600, the logical channel is not within the print range, the channel data is invalid, and no ink is discharged when the channel data is invalid.
When the channel data is valid, please refer to fig. 5, the step S4: extracting the channel data from the printing memory according to the storage address, and processing the channel data and the printing parameters to obtain printing data specifically includes:
s41, when the channel data is valid, extracting the channel data according to the storage address;
and S42, processing the channel-free data according to the task parameters to obtain printing data.
The specific treatment includes one or more of a masking treatment, a feathering treatment, and a combining treatment. Processing the task parameters for masking includes: the end pixel position of the start mask, the start pixel position of the end mask. Referring to fig. 3, when the Y-axis accumulator value reaches 300, the channel data is valid, but not all the channel data are data of the target image, so that the data not belonging to the target image need to be masked, for example, the channel data corresponding to the logical channel PCH0, the logical channel PCH1, the logical channel PCH4, the logical channel PCH5, and the logical channel PCH6 in this embodiment need to be masked, the channel data corresponding to the logical channel PCH0, the logical channel PCH1, the logical channel PCH4, the logical channel PCH5, and the logical channel PCH6 are masked according to the task parameter to be processed into no ink data, at this time, the end position 600 pixel position of the logical channel PCH1 is the end pixel position of the start mask, and the start mask area is all the logical channels in the 0-600 pixel area, the start of the logical channel PCH4, i.e. 1200 pixel locations, is the start pixel location of the end mask, and the end mask region is all logical channels of the 1200 to 2100 pixel regions; when certain images need higher printing quality, feathering the images during printing to ensure that the printing effect is better, and specifically performing AND operation on channel data and feathering template data to obtain printing data; when the variable image is printed, each image in a class of variable images has a same background image, and the same position of each image has a variable image which changes according to a certain rule.
In another implementation, the method further comprises:
inputting the printing data corresponding to the logic channel number into a corresponding physical channel for ink-jet printing according to the logic channel number; the physical channel corresponds to a spray head or a color or a row of spray holes, and therefore image data are correctly distributed to the corresponding physical spray heads.
