Description
Technical field
The present invention relates to ink-jet printing technology field, be specifically related to a kind of accurately process first in ink-jet printing technology
The predrive method of drop.
Background technology
Ink jet printing ink-jet printer to be used, ink-jet printer is a kind of and object non-contacting ink jet printing type is printed
Equipment, it is not limited by any material, can be at plank, glass, crystal, metallic plate, floor tile, ceramics, CD, Ya Ke
The surfaces of various materials such as power, lucite, EVAKT plate, leather, silica gel, plastic cement, PP, PE, PVC, cloth, adhesive sticker, stone material are entered
Row printing.And, whether simple block colored pattern, full color pattern, still have the pattern of excessive color, can one-step print
Completing, it is not necessary to plate-making, printing down and repetition chromatography, color is beautiful, and effect is true to nature, image adhesive force waterproof, sun-proof, wear-resistant is strong,
Colour-fast, machine operation is simple, steady performance.Along with the development of electronics technology, ink-jet printing technology has become
For large-screen display, the important technology in the image conversion electronic application such as RF identification and printed circuit board (PCB).
Meanwhile, the requirement to Ink-jet Printing Quality also gradually steps up.May be required for dissimilar many times
Blasting materials from print start the most accurately spray.Can accurately spray, the most to control all of material
Propose and trigger the method that the amount of droplets of injection improves accuracy of spray, i.e. drop on demand ink jet mode each time by change.But
It is that this research work does not the most make substantial progress up to now, meanwhile, controls to spray position by controlling drop ejection number
It is all uniform for putting the injection each time also needing to assume in spraying in a large number, and this means that and wants between drop amount and total spray volume
Linear.
But, due to blocking or the impact such as the evaporation of nozzle oral area solvent and capillarity, open most in injection
In a period of time begun, the liquid level of shower nozzle presents first quarter moon shape.In this case, the injection quantity of drop and total spray volume it
Between and non-linear relation.Therefore, the most inoperative by the way of controlling injection amount of droplets and improving accuracy of spray.
Summary of the invention
It is an object of the invention to provide a kind of predrive method accurately processing the first drop in ink-jet printing technology,
Use predrive method, the problem that printing initial stage nozzle injection accuracy is low can be overcome, it is to avoid the printing initial stage is because of spray nozzle clogging
Or the evaporation of nozzle solvent causes spraying failed phenomenon.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of predrive method accurately processing the first drop in ink-jet printing technology, is just being carried out at ink-jet printer
Before formula drives ink-jet, ink-jet printer is loaded predrive voltage and carries out predrive, the process of stopping out during simulation actual ejection
Make nozzle be completely filled with ink, but do not spray ink droplet.
According to above scheme, described predrive voltage be described formal drive time voltage 50%～70%.
According to above scheme, the number of times of described predrive is 50～300 times.
Due to ink jet process be a series of digit pulse drive under stop out, the process of ink-jet.But, ink jet process needs
Want driving voltage to reach certain amplitude to complete.Predrive process is by under driving voltage effect during simulation actual ejection
Stop out process, the first quarter moon shape liquid level that nozzle causes due to evaporation is filled with, makes nozzle be completely filled with ink, but do not spray
Ink droplet.
When predrive voltage magnitude is too small, predrive can not reach to make up evaporation reduction first quarter moon shape liquid level position
Requirement；And when predrive ends of the earth amplitude is excessive, just have ink ejection.As long as predrive voltage is at formal driving voltage
Within the scope of 50% to 70%, it is possible to realize stopping out in the case of not spraying ink droplet process, reaches the mesh of applying nozzle
's.The droplet formed under predrive voltage, process is similar to the formation of ink droplet, but will not be half under the effect of predrive
Month liquid level fractures, and makes ink spray.
Predrive each time all can only the very small part of filling level, need the repeatedly predrive process could be complete by nozzle
Full packing.Owing to the evaporation rate of different solvents is different, even and if same solvent is possibly also owing to the difference of waiting time
Causing evaporation time different, during printing, the sinking degree of first quarter moon liquid level is all different every time.Accordingly, it would be desirable to according to first quarter moon liquid level
Sinking degree, calculate quasi-optimal predrive number of times, then carry out predrive.When predrive number of times is less than 50 times, nozzle
Fill not exclusively, it is impossible to reach preferable jeting effect；When predrive number of times is more than 300 times, predrive process can be caused to overflow
Long, also it is a kind of waste simultaneously.
The invention has the beneficial effects as follows:
1) present invention reduces the evaporation impact on inkjet printer nozzles first quarter moon shape liquid level dramatically, makes print
The injection accuracy of brush initial stage nozzle is greatly improved；
2) method that the present invention uses repeatedly predrive, makes printing initial stage nozzle just can fill up, can avoid the printing initial stage because of
Spray nozzle clogging or the evaporation of nozzle solvent cause spraying failed phenomenon and occur.
Detailed description of the invention
Below in conjunction with embodiment, technical scheme is illustrated.
Embodiment 1:
The present invention provides a kind of predrive method accurately processing the first drop in ink-jet printing technology, prints in ink-jet
Before brush machine formally drives ink-jet, ink-jet printer is loaded predrive voltage and carries out predrive, during simulation actual ejection
The process of stopping out make nozzle be completely filled with ink, but do not spray ink droplet.
Further, during described formal driving, voltage is 100V, described predrive voltage 60V；The number of times of described predrive
It it is 200 times.
The jet firing frequency of the ink-jet printer of the present embodiment is 300Hz, prints after ink evaporates 3 hours,
When predrive number of times is 200 times, nozzle both can be made to be filled up completely with.Seen by microscope: there is no predrive
In the case of, the printing initial stage has loss and the deformation of a large amount of printing points, and when predrive number of times reaches 200 times, printing quality
Can reach the stage that human eye cannot be distinguished by.
Embodiment 2:
The method of the present embodiment is with implementing 1, and difference is: described predrive voltage 50V；The number of times of described predrive
It it is 300 times.
