Above-mentioned inkjet printing methods are avoided by the currently available inkjet print head selected in ink jet printing process
In there is ink-jet uneven the phenomenon that being even unable to complete print out task, since the inkjet print head completion of different parameter informations is beaten
Print task needs the different time, according to the parameter information of the print job information of acquisition and inkjet print head, prints to completion
The number amount and type of the inkjet print head of task are selected, to ensure that selected inkjet print head can smoothly complete printing
Task, use are more convenient.
As shown in Fig. 2, in one embodiment, print out task includes task parameters and preset printing limiting time, step
Rapid S200 includes step S220 and step S240.
Step S220, the parameter information of the currently available each inkjet print head of comparative analysis obtain comparison result.
The parameter information of inkjet print head includes Nozzle Parameter and print parameters, and Nozzle Parameter may include that nozzle is sprayed
Parameters, the print parameters such as drop speeds, droplet volume and ink droplet angle when ink printing may include the printing of inkjet print head
The parameters such as speed.Wherein, drop speeds refer to the speed of the ink droplet drops of the nozzle of inkjet print head, the printing of inkjet print head
Speed refers in print procedure, the relative moving speed of inkjet print head and printing substrate.It, can be with during comparative analysis
First classify to all kinds of parameters, determine parameter priority, is classified comparative analysis, and be directed to same class parameter, ratio can be passed through
It is compared compared with the length the time required to when completing same task, thus to obtain comparison result.
The Nozzle Parameter of inkjet print head can be obtained according to titration correction result in one of the embodiments, be had
Body may include: to carry out titration correction to each inkjet print head respectively, obtain the titration correction knot of each inkjet print head
Fruit, by titration correction as a result, obtaining the Nozzle Parameter information of inkjet print head.Titration correction refers to the spray to inkjet print head
The parameter of mouth, such as drop speeds, droplet volume, ink droplet angle etc. are corrected according to target value, and obtain the determination after correction
The process of parameter value can determine in inkjet print head according to the titration discriminant parameter and print out task of setting and meet titration rule
The nozzle quantity of lattice and position.Nozzle Parameter information, including obtained in inkjet print head from titration correction result and meet titration
The nozzle quantity of standard and position, drop speeds, droplet volume, the information such as ink droplet angle.According to the titration discriminant parameter of setting,
It can choose the inkjet print head for providing the Nozzle Parameter information for meeting titrimetric standard.
Print parameters refer to inkjet print head in addition to other in titration correction course other than fixed Nozzle Parameter
Parameter information, such as print speed, the solid content etc. of ink.The solid content of ink refer to the printed material in inkjet print head
Remainder accounts for the mass percent of total amount after drying under rated condition, and same kind of material, solid content is different, required ink
It is different to drip quantity, the print time is also different.Wherein, the solid content of ink can by the ink that is packed into inkjet print head into
Row control, print speed before printing starts and can be configured and adjust in printing technology handoff procedure.It is appreciated that
The acquisition of print parameters and Nozzle Parameter in no particular order, can first obtain print parameters, can also first obtain Nozzle Parameter, may be used also
To obtain print parameters and Nozzle Parameter simultaneously.
Step S220 includes: by comparing the Nozzle Parameter in analysis parameter information, to spray in one of the embodiments,
Black print head carries out priority ranking, and determines the inkjet print head preferentially used.
When print parameters are identical, the time needed for the inkjet print head of comparison different spray nozzles parameter completes print out task.
Specifically, currently available inkjet print head is ranked up according to nozzle quantity, obtains inkjet print head queue, task based access control
Each inkjet print head that parameter and nozzle quantity obtain inkjet print head queue executes the time required for print out task, obtains
Print time set, determines the inkjet print head preferentially used.For example, being set for same sheet glass substrate and same pixel
Meter, i.e. glass substrate size and pixel size are it is known that according to process requirements, and the ink-jet for carrying out hole injection layer ink material is beaten
Print technique, estimated in each pixel to need the ink droplet number dripped be it is known that the spray that will meet titrimetric standard in No. 1 inkjet print head
The substitution of mouth number is calculated, the situation for being 100 in the nozzle number for meeting titrimetric standard, for given pixel quantity and pixel ruler
It is very little, such as the print time of completion is 100s；And the nozzle number 70 for meeting titrimetric standard in No. 2 inkjet print heads is substituted into meter
It calculates, such as completes print time demand 130s, than No. 2 inkjet print heads are short the time required to No. 1 inkjet print head, system meeting at this time
Preferentially call No. 1 inkjet print head.Due to being spray corrected according to target value, therefore different in titration correction course
The difference of drop speeds between mouth, droplet volume, ink droplet angle is smaller, pays the utmost attention to the nozzle quantity pair for meeting titrimetric standard
The influence of print time.When inkjet print head identical there are multiple nozzle quantities for meeting titrimetric standard, it can be integrated
His influence of the different spray nozzles parameter to the print time determines the inkjet print head preferentially selected.
Step S220 includes: by comparing the print parameters in analysis parameter information, to spray in one of the embodiments,
Black print head carries out priority ranking, and determines the inkjet print head preferentially used.
When Nozzle Parameter is identical, the time needed for comparing the inkjet print head completion print out task of different print parameters,
Such as when print out task determines, if having different print speed, the fast inkjet print head of print speed completes print out task
The required time is shorter, the inkjet print head that preferentially print speed can be selected fast；If the similar ink with different solid contents
The inkjet print head of material, the high inkjet print head of ink solids is shorter the time required to completing print out task, can preferentially select
The high inkjet print head of ink solids.When ink solids and print speed be not simultaneously as the adjustment phase of print speed
Replacement compared with different ink jet print heads is more simple, can pay the utmost attention to influence of the ink solids to the print time.
It is appreciated that influence condition can also preferentially be selected according to specific gravity is influenced, it can also be according to preset condition to influence item
Part is preferentially selected.
Step S220 includes: by comparing the Nozzle Parameter in analysis parameter information, to spray in one of the embodiments,
Black print head carries out priority ranking according to Nozzle Parameter, the optimal inkjet print head of Nozzle Parameter is determined, when there are multiple sprays
When the optimal inkjet print head of mouth parameter, in the parameter information of analyzing the optimal inkjet print head of multiple Nozzle Parameters by comparing
Print parameters, the inkjet print head optimal to multiple Nozzle Parameters according to print parameters carry out priority ranking, and determine spray
The optimal inkjet print head of print parameters in the optimal inkjet print head of mouth parameter.
When the Nozzle Parameter of inkjet print head and print parameters are all different, compared to print parameters, after titration correction
Nozzle Parameter is generally relatively fixed, and is affected to the print time, first considers that the preferential of Nozzle Parameter uses grade, selection spray
Shortest inkjet print head the time required to completing print out task in the different inkjet print head of mouth parameter, believes further according to print out task
The print parameters of breath and shortest inkjet print head of multiple used times, determine that the different shortest ink-jet of multiple used times of print parameters is beaten
The inkjet print head preferentially used in print head.
Step S240, task based access control parameter, preset printing limiting time and comparison result select inkjet print head.
According to comparison result, the inkjet print head of better performances can choose out, but join for completing different tasks
Number, it may be desirable to which the different print times, the length of print time is to determine the whether uniform essential condition of printing-filming, because of base
The region and the last region for carrying out inkjet printing that inkjet printing is first carried out on plate will lead to ink material because interval time is too long
The degree of drying difference of material is too big, then carry out it is subsequent be dried under reduced pressure technique after, it may appear that film forming film quality it is uneven, so necessary
Setting printing limiting time.According to the print parameters in print out task, selecting in comparison result can limit in preset printing
Fix time it is interior complete print job inkjet print head.The selection of inkjet print head include the selection to inkjet print head type and
The selection of quantity determines the preferential using grade of inkjet print head according to different parameter informations, and selects the spray preferentially used
Black print head, and judge whether the inkjet print head of selection can complete print out task in preset printing limiting time, work as institute
Take time is more than to increase the quantity of corresponding inkjet print head, if quantity is inadequate, according to inkjet print head when printing limiting time
The second inkjet print head for preferentially using of use priority selection and determine usage quantity.
Specifically, as shown in figure 3, parameter information includes the print speed of inkjet print head in one of the embodiments,
Step S220 specifically: currently available inkjet print head is ranked up according to print speed, obtains inkjet print head queue.
Print speed is to determine an important factor for completing print out task required time, and print speed is faster, is completed same
It is shorter the time required to print out task, according to the print speed of each inkjet print head, faced by print speed near slow sequence
Inkjet print head is ranked up, and each inkjet print head arranged in sequence is inkjet print head queue.
Step S240 includes step S242 and step S244.
Each inkjet print head that step S242, task based access control parameter and print speed obtain inkjet print head queue executes
Time required for print out task obtains print time set, and the print time includes the most short print time.
Inkjet print head is sorted after obtaining inkjet print head queue according to print speed, since print out task needs are limiting
It fixes time interior completion, needs task based access control parameter and print speed, each inkjet print head for obtaining inkjet print head queue is held
Time required for row print out task, each inkjet print head can correspond to the different print times because print speed is different, spray
The print time in inkjet print head and print time set in black print head queue corresponds, wherein print speed is most
The print time of fast inkjet print head is most short.
Step S244 obtains the quantity of most short print time corresponding inkjet print head and inkjet print head.
According to the inkjet print head queue arranged according to print speed, the most fast inkjet print head of print speed can be selected preferentially
Use is selected, as most short print time corresponding inkjet print head, and after having selected inkjet print head, it needs to judge most
Whether the short print time is limiting within the print time, when printed between be more than limit the print time when, obtain inkjet print head
Quantity, can select to spray by the relationship of product between print time and the quantity of inkjet print head and printing limiting time
Black print head makes print time control within a limited period of time.
Specifically, when the product between most short print time and the quantity of inkjet print head is greater than or equal to preset printing
When limiting time, most short print time corresponding inkjet print head is selected based on preset printing limiting time.When most hand-to-hand fight in tights prints
It is corresponding from the second short print time when product between time and the quantity of inkjet print head is less than preset printing limiting time
Inkjet print head continue to select.
For example, in actual print procedure, it is desirable that complete print out task in 120S, printed in inkjet print head queue
It is 80S the time required to fastest i.e. print time shortest first inkjet print head, short the second ink-jet of print time second
It is 100S the time required to print head, is 150S the time required to the short third inkjet print head of print time third, at this point it is possible to select
It selects first inkjet print head and completes print out task, when printing limiting time becomes 60S, first inkjet print head is not
Energy print out task should increase the quantity of the first inkjet print head at this time, while use two the first inkjet print heads.If for
First inkjet print head quantity of selection only one, then select two the second inkjet print heads to complete print out task, with such
It pushes away, completes the selection to inkjet print head.
It is appreciated that the selection of the different inkjet print head of other parameters information such as Nozzle Parameter or print parameters can also be with
It is selected according to the above method.The different inkjet print head such as nozzle quantity, inkjet printing head of different ink materials etc..
As shown in figure 4, in one embodiment, after step S300, further includes:
Step S420, when a task parameters in print out task update, by analyzing update task parameters,
Comparison result the time required to obtaining when present day ink-jet print head completes current print out task and updates print out task.
Step S440, if the required time for completing to update print out task is less than the required time for completing current print out task,
It then completes to update print out task using present day ink-jet print head.
Step S460, if the required time for completing to update print out task is greater than the required time for completing current print out task,
Then according to the required time and printing limiting time for completing update print out task, the quantity of present day ink-jet print head is adjusted.
In InkJet printing processes, different processes can be related to, may be existed between every one different process a certain
The change of parameter, at this time, it may be necessary to which the specification and quantity to inkjet print head are adaptively adjusted.As one in print out task
When task parameters update, such as variation of Pixel Dimensions to be printed, for convenience of describing, this sentences the tightness degree of pixel unit arrangement
Pixel Dimensions are distinguished, pixel unit arranges the high-resolution Pixel Dimensions that are known as of relative close, pixel unit arrangement
The of a relatively loose Pixel Dimensions for being known as low resolution, the pixel of different resolution need the different print times.Such as have two
Kind pixel design: the first Pixel Dimensions is length: 0.175mm, wide: 0.060mm, pixel column and line space: 0.095mm, pixel
Column and column pitch: 0.115mm；Second of Pixel Dimensions is length: 0.222mm, wide: 0.065mm, pixel column and line space:
0.111mm, pixel column and column pitch: 0.111mm.In actual application, under the conditions of same glass substrate size, first
The number that than second picture element matrix of number of kind picture element matrix arrangement arranges is more, i.e., the first pixel arrangement is closer, institute
The print time needed with the first pixel compares the print time of second of pixel with regard to longer.In printing technology, there are
A kind of pixel print out task is completed, when needing replacing to the print out task of second of pixel, based on the analysis results, second of pixel
Print time it is shorter with respect to the first pixel, therefore can directly using complete the first pixel print out task inkjet print head it is complete
At the print out task of second of pixel.Second of pixel print out task is completed if it exists, needs replacing beating for the first pixel
When print task, based on the analysis results, the print time of second of pixel is shorter with respect to the first pixel, needs to obtain use at this time
The inkjet print head of second of pixel print out task is completed to complete the time of the first pixel print out task, is beaten if the time is greater than
Limiting time is printed, then increases the quantity of inkjet print head, is printing print time control within limiting time.
In printing technology, each substrate may need to complete multilayer printing, and different film layers is needed using variety classes
Marking ink material, corresponding different film thickness, the different print out task of film layer needs the inkjet print head of different inks, according to
After type of film determines the material of ink, it is also necessary to judge whether the quantity of inkjet print head needs to adjust.Assuming that material
Expect that the parameter of the inkjet print head of A is identical as material B's, it is 25um that the first film layer, which needs materials A printing film thickness, and the second film layer needs
Wanting material B printing film thickness is 60um, establishes the corresponding relationship of film thickness and respective material number of ink droplets in pixel unit, such as uses material
The pixel unit for expecting A printing film thickness 25um needs, using the pixel unit of material B printing film thickness 60um, to need to make using 12 drops
With 18 drops, number of ink droplets as needed, it can be determined that obtain in the inkjet print head using identical parameters, complete only have film layer
When the print out task of variation, the length the time required to each film layer is printed, and inkjet printing can be determined by the length of time
The quantity of head.
As shown in figure 5, in one embodiment, after step S300, further includes:
Step S520, by the analysis to print parameters are updated, is obtained when a print parameters of inkjet print head are updated
It takes present day ink-jet print head and updates the comparison result the time required to inkjet print head completes current print out task.
Step S540, if update inkjet print head the time required to be less than present day ink-jet print head the time required to, use with
The equal update inkjet print head of present day ink-jet print head quantity is completed to update print out task.
Step S560, if the time required to being greater than present day ink-jet print head the time required to updating inkjet print head, according to complete
At inkjet print head required time and printing limiting time is updated, adjustment updates the quantity of inkjet print head.
When print out task does not change, but the print parameters of inkjet print head are when for example print speed changes, because
It is considerably shorter for the print speed fast inkjet print head completion same print out task time, therefore, it is big after print speed adjustment
When current print speed, the quantity for being not required to increase inkjet print head can complete print out task in printing limiting time,
