Description

Technical Field

Background

With the wide application of computers in graphic or word processing, printers are becoming more and more popular, and people can conveniently output characters or graphics in computers to pictures through the printers.

The Onepass printing is that the length direction (X direction) of a nozzle of a spray head is vertical to the moving direction (Y direction) of a printing medium, the spray head is generally fixed, the printing medium passes through the lower part of the spray head once to obtain a pattern to be printed, and the printing medium moves continuously without pause. Oneeglass printing has the advantages of high efficiency and large output, and is suitable for a large-batch and continuous production mode.

The existing Oneeglass printing equipment is formed by splicing a row of spray heads end to end, and when the width of a product in the arrangement direction of the spray heads is equal to the sum of the widths of the whole spray heads, the utilization rate of one-time printing spray heads can almost reach 100%; however, when the breadth of the product along the arrangement direction of the nozzles is small, if the breadth of the product is equal to the breadth of one nozzle, only one nozzle discharges ink at the moment, and other nozzles do not discharge ink, so that the utilization rate of the nozzles during printing is low, and the resource waste is serious. In the printing process of the variable data image and the background image, different production modules print different variable data contents and background images, and the contents of the variable data contents and the background images are pre-stored in a memory according to corresponding numbers. But each production module is triggered, and the process of creating the task is independent. Therefore, the problem that the work of different production modules is asynchronous, so that the serial number of the variable data cannot be matched with the serial number of the background image occurs, and the printer is in error in printing. Therefore, how to ensure that the printing data corresponding to the common nozzle can be accurately extracted to the corresponding production line when the task target image among the multiple production lines is adaptively matched and printed is also a difficult problem to be solved urgently in the technical field of inkjet printing.

Referring to fig. 1, an embodiment of the present invention provides a multi-line print task adaptive matching method, where a first module for maintaining a background map and n second modules for maintaining variable data are arranged, n is greater than or equal to 1, and n is an integer; configuring the number of printing copies for the first module, and configuring variable data ID values matched with the number of printing copies; creating a first printing task of the first module and a second printing task of the second module; counting the printing times of the first module and transmitting the count value to the second module; judging whether the count value is equal to the variable data ID value of the second module; and when the count value is equal to the variable data ID value of the second module, reading the printing data of the first module and the second module and printing. The invention ensures the accuracy of the self-adaptive matching of the task target images of each production line in variable data printing. The method specifically comprises the following steps:

s1, setting a first module for maintaining a background picture and n second modules for maintaining variable data according to printing requirements, wherein n is greater than or equal to 1 and is an integer;

preferably, the print data of the background map and the print data of the variable data are maintained by different modules, respectively. A first module maintains a background picture, and different background pictures are maintained by different first modules; a second module maintains a variable data tag, and different variable data tags are maintained by different second modules.

S2, configuring the number of printing copies for the first module according to the printing requirement, and configuring variable data ID values matched with the number of printing copies;

in the present embodiment, each number of printed copies is provided with a number. The ID value indicates that a number corresponding to the number of printed copies is arranged for each variable data. For example, if the number allocated to the first printed copy is 1, the corresponding variable data ID value is 1, and if the number allocated to the second printed copy is 2, the corresponding variable data ID value is 2. It is understood that the variable data may be one tag, or may be two tags, and the number of tags of the variable data is not specifically limited herein, but the ID values of the tags in the same variable data are the same.

S3, creating a first print task of the first module and a second print task of the second module;

preferably, the first print job of the first module and the second print job of the second module are independently controlled, and the background map of the first print job and the variable data label of the second print job are printed on the same printing medium.

S4, counting the printing times of the first module and transmitting the count value to the second module;

specifically, when the same background image is printed a plurality of times but the variable label on the background image is varied, the number of copies of the currently printed background image needs to be counted. Count 1 when one background image is printed, count 2 when two background images are printed, and so on, and the count value of the printed background images is transmitted to the second module.

S5, judging whether the count value is equal to the variable data ID value of the second module:

for example, when the number of copies of the background image is 1, the counter counts and sends a count value of 1 to the second module. At this time, the variable data ID value corresponding to the number of copies printed on the background image in the second module is also 1. It is understood that the ID values of the plurality of tags in the variable data are all 1.

S6, when the variable data ID value is greater than the count value, not performing the second print job dequeuing operation;

preferably, the dequeue operation refers to reading the print job information that is queued at the front, and deleting the print job information in the queue when printing is completed. In this embodiment, when the variable data ID value is greater than the count value, the second print job does not perform the dequeue operation, and the variable data ID value in the second print job remains unchanged. At this time, the count value of the background map is still increasing until the count value is equal to the variable data ID value, and the first print job and the second print job are started to be executed.

S7, when the variable data ID value is smaller than the count value, the dequeue operation of the second print job is executed according to the difference value of the variable data ID value and the count value until the variable data ID value and the count value are equal;

specifically, when the variable data ID value is smaller than the count value, the second print job performs dequeue operation for multiple times, the variable data ID value continues to increase, and the count value of the print background map is not changed until the count value is equal to the variable data ID value of the second module.

And S8, when the count value is equal to the variable data ID value of the second module, reading the printing data of the first module and the second module and printing.

Preferably, the control system compares the count value with the variable data of the second module, and reads and prints the print data of the first module and the second module when the count value is equal to the variable data ID value of the second module.

Preferably, the first module and the second module are respectively an independent print job creating, managing and printing processing system, each module is configured with an independent print job data cache space, and each module maintains independent data to be printed.

Preferably, the creating the first print job of the first module and the second print job of the second module includes:

Preferably, the task queue content of the first print task is a data address and the number of prints of the background image printed this time in a first memory space corresponding to the first module, and the task queue content of the second print task is a data address and an ID value of the variable data printed this time in a second memory space corresponding to the second module.

Application example 1

Several concepts are first defined:

a module: a set of independent task creation, management, print processing system; each module has an independent task data cache space; maintaining queues of task data in an independent cache space, wherein the queues comprise initial addresses and ID information of the task data in the cache space; there is a separate work queue.

task: for a printing process, a static background map and several copies of printed labels are used in the printing process.

work: printing a background picture and a plurality of corresponding printing labels as a work in the process of printing a task once; when a work is printed once, a trigger signal needs to be printed, and a printer is triggered to create a printing work. It can be seen that the print label of each work is different during the printing task, and the background image is the same.

The background image may be a fixed picture, printed n times in one print task. For example, the printing content of each work comprises 1 background picture and 3 printing labels; 3 printed labels need to be matched and each time the content is dynamically variable.

Because the static background images are always large, the static background images are repeatedly used after being loaded until the static background images are not needed any more; furthermore, because flexible switching of background graphs needs to be realized and the number of words of each task can be freely and flexibly defined, information (data addresses) of a plurality of background tasks are cached through a RAM memory; the logic channel receives the configuration from the user of the upper computer, and calculates and generates a printing task (including information of a storage starting address of the current background image data in the ddr and the number of work printed by the current task) to enter a queue according to the user requirement;

each module maintains a work queue.

When the channel corresponding to the module reads data, the address of the task is calculated after the printing label information is read from the corresponding work queue according to the sequence. And taking out the information of the next label from the queue only after all the current labels are printed.

The multi-production-line printing task self-adaptive matching method provided by the embodiment of the invention comprises the following specific steps of:

1. the module (first module) for printing the background picture adopts an ARM processor to maintain a queue, the content of the queue is the information of the background picture to be printed at this time, and the information mainly comprises a data address and the number of copies of the background picture to be printed at this time.

2. The other enabling modules (second module) maintain a word queue. The queue is the labels to be printed next and the ID of each label;

3. the system ensures that the IDs of the work are coordinated with each other and correspond to the background picture. Assume that there are two tasks in the background map queue: firstly, printing a background picture 1, and printing 100 copies; printing a background picture 2 after printing is finished, and printing 50 parts, wherein 100 parts of works corresponding to the background picture 1 must be printed in all module work queues according to a set sequence, and the ID information is 0-99; then, the ID information of 50 corresponding to the background figure 2 is printed and is 0-49.

4. When the tasks are synchronously created, a task printing process is performed once, and the first module for printing the background graph only needs to perform a task queue dequeuing operation once when the task is finished. The first module that prints the background map counts work for one task process, and sends the count value to the other modules (second module).

5. Except for the first module, when each work of each second module creates a task, the ID of the work in the current work queue is judged to be compared with the count value of the work sent by the first module, and if the ID is large, the second module does not execute the work dequeuing operation. And if the ID is small, the second module executes a plurality of times of queue-removing operations until the ID of the work in the queue is equal to the count value of the work of the current first module. Thus, self-adaptive synchronization of work among modules during long-time printing is ensured.

The production line comprises at least 1 physical channel, and all the physical channels can be located in one Oneepass printing device or a plurality of Oneepass printing devices.

Preferably, the printing memory has a plurality of copies, each copy of the printing memory correspondingly stores data to be printed of one production line, each copy of the printing memory correspondingly sets a task queue to be printed, each written task needs to be queued, and each read task needs to be queued. Referring to fig. 3, in this example, the print data corresponding to each production line is stored separately, the print task of each production line is triggered separately, and after the print task is triggered, the print data is extracted from the print memory according to the print task queue to the print control system, distributed to the data interface of each production line through the print control system, and then sent to the corresponding printing device.

Referring to fig. 5, the corresponding relations between the logic channels and the generating lines are that the logic channels LCH 0-LCH 11 belong to production line 1, the logic channels LCH 12-LCH 23 belong to production line 2, the logic channels LCH 24-LCH 35 belong to production line 3, and the logic channels LCH 36-LCH 47 belong to production line 4; the specific establishment of the corresponding relationship is that each physical channel and each logical channel are numbered, the production line corresponding to each logical channel and the relative position of each logical channel in the corresponding production line can be determined according to the numbers, the data length corresponding to each logical channel is equal to the length of the physical channel, and the length of the physical channel represents the number of nozzles owned by the physical channel.
