Description
Technical Field
The present invention relates to an inkjet printing method, and more particularly, to an inkjet printing method for ensuring stable ejection of ink droplets during an increase in firing frequency of a head by varying a driving voltage.
Background
Ink jet printing, which is a process of forming an image by ejecting ink droplets onto a substrate, has many advantages: low printing price, high printing quality, capability of manufacturing high-grade products, large color capacity, high speed, variable information printing and customization and the like. At this stage, piezoelectric ink jet printing has been widely used, which is based on the principle of pressing out ink from nozzles by applying a voltage to a piezoelectric ceramic to cause a high-speed and slight deformation. When the piezoelectric ceramic is subjected to external pulse voltage, the piezoelectric ceramic deforms, and the volume of the ink cavity of the nozzle is reduced. Thus, a drop of ink is ejected from the nozzle. Then, the piezoelectric ceramics are restored, and new ink enters the nozzle due to the surface tension. By arranging a large number of nozzles side by side, the desired jet width and resolution can be achieved.
At present, the ink jet printing is divided into two types of motion modes, one is scanning type ink jet printing, and the other is one-pass (Onepass) ink jet printing. In the scanning type ink jet printing process, the reciprocating motion of the spray head sprays ink drops to an object to be printed below, at the starting stage of the reciprocating motion of the spray head, the spray head is in the acceleration process, the sprayed ink drops have acceleration relative to the object to be printed below, the drop points of the ink drops can change, so that qualified images cannot be printed, at the moment, the spray head does not spray ink, the spray head starts to spray ink drops to print images at a constant speed after accelerating to a specified printing speed, and the spray head also does not spray ink to the object to be printed below in the deceleration process after the uniform-speed printing of the spray head in the same way. In the one-pass (Onepass) ink-jet printing, a printing spray head is fixed, a medium to be printed below the spray head is conveyed at a high speed, the medium to be printed is already conveyed for a long distance at the beginning of acceleration, and according to actual requirements, secondary variable data printing is sometimes performed on the processed medium to be printed, so that the cost of the medium to be printed is high in the printing case, or the medium to be printed serving as a packaging material is expensive per se and is not printed, so that the image is printed in the acceleration process.
On the other hand, different nozzles have respective ejection characteristics, which are expressed by the relationship between the firing frequency of the nozzle and the ink droplet ejection speed of the nozzle, in an ideal state, the ink droplet ejection speed in the whole firing frequency increasing process is basically kept stable, and an image with good quality is easily printed. In an actual state, the ink drop ejection speed is unstable due to different firing frequencies of the nozzles, and generally, the ink drop ejection speed is basically stable at the beginning of a period of time, and the ink drop ejection speed fluctuates obviously up and down along with the acceleration transmission of a printing medium and the increase of the firing frequency. The ejection characteristic of the nozzle is an inherent characteristic of the piezoelectric ceramic: the ceramic generates resonance phenomenon under fixed frequency, and the abnormal jet state is inevitable at the moment. In this abnormal state, the image with qualified quality cannot be printed, and the speed is generally not increased to this area in the conventional printing process. And along with the improvement of the ink manufacturing level, the requirement of higher printing speed can be met, at the moment, if the instability of the spray characteristics of the spray head during high ignition frequency can be overcome, the printing is continuously carried out from the beginning to the high ignition frequency stage, and the uniform speed transmission is kept after the high ignition frequency stage is reached, so that the high-speed transmission printing can be realized, and the ink jet efficiency is improved.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide an ink-jet printing method which can overcome the inherent defects of the ejection characteristic of a nozzle and ensure good image printing quality in the whole process in the process of continuously accelerating the transmission of a printing medium.
The technical problem of the invention is solved by the following technical scheme: an inkjet printing method is provided, characterized by comprising the steps of:
a. dividing the spray characteristic curve of the spray head into intervals according to the waveform change and the printing effect;
b. testing the divided intervals to find the printing driving pulse corresponding to each interval;
c. and formally starting printing, wherein the circuit control board performs drive control on each interval in a mode of switching the corresponding printing drive pulse in the printing process.
In the above printing method, the number of the printing driving pulses in step b is at least two.
In the above-described printing method, the at least two drive pulses include a difference in waveform rise time Tr or fall time Tf or pulse duration Tw or voltage range.
In the printing method, the pulse variation time is in the order of microseconds.
In the above printing method, the ejection characteristic curve of the ejection head in step a reflects a relationship curve between the firing frequency of the ejection head and the ejection speed of the ink droplet.
In the above printing method, as the firing frequency of the head increases, the fluctuation in the magnitude of the ink droplet ejection speed becomes gradually conspicuous.
In the above printing method, as the firing frequency of the head increases, the ink droplet ejection speed starts to be stable, then the fluctuation in size is significant, and finally, the ink droplet ejection speed tends to be stable.
In the printing method, the circuit control board in the step c is a spray head control board, and the FPGA in the spray head control board performs switching drive pulse operation.
In the above printing method, the FPGA may be replaced with a software control.
In the above printing method, the print driving pulse corresponding to each section in step b may be replaced by a method of increasing or decreasing the image print resolution, and the head control board in step c controls each section in a manner of switching the print resolution.
The ink-jet printing method can switch the compensation driving voltage or improve/reduce the image printing resolution under the condition that the abnormal spraying state occurs when the piezoelectric ceramics in the spray head generates resonance in the process of increasing the ignition frequency, thereby ensuring the good printing quality; meanwhile, in the process from printing to accelerating to a high transmission speed, the image with qualified quality can be printed all the time, the printing efficiency is improved, and the waste of paper is avoided.

Detailed Description
The ink jet printing method of the present invention will be described in detail with reference to the following examples and accompanying drawings.
Example one
Fig. 1 is a schematic diagram of a relationship curve between a nozzle firing frequency and an ink droplet ejection speed, and in particular is a speed ejection curve in which the nozzle firing frequency is in a range from 0 to 50kHz (50 kHz is the maximum firing frequency of the nozzle), and most of ink droplets (more than 90%) are ejected from the nozzle. It can be seen from the figure that the ignition frequency reaches 6.5m/s from the position A, then the ignition frequency basically tends to be stable, the speed change is not significant until the point O, the corresponding nozzle ignition frequency at the position of the point O is 22kHz, the ignition frequency interval of the section is defined as a first interval, and the ignition frequency of the first interval is more than 0kHz and less than 22 kHz; after the point O, the waveform representing the change of the speed size starts to have a small amount of fluctuation, the ignition frequency of the corresponding spray head at the position of the point P is 29kHz, the ignition frequency interval from the point O to the point P is defined as a second interval, and the ignition frequency of the second interval is more than 22kHz and less than 29 kHz; after the point P, the speed changes obviously, the corresponding firing frequency of the nozzle at the point Q is 40kHz, the firing frequency interval from the point P to the point Q is defined as a third interval, and the firing frequency of the third interval is more than 29kHz and less than 40 kHz; the fluctuation of the speed after the point Q is more severe, and a section after the point Q is defined as a fourth section, and the ignition frequency of the fourth section is more than 40kHz and less than 50 kHz. After the printer is started, along with the accelerated transmission of the printing medium, the firing frequency of the nozzle is gradually increased, when the firing frequency is in a first interval range, the ejection speed of the ink drops is basically stable, the quality of the image printed by the nozzle is easily controlled in a qualified effect, and when the firing frequency of the nozzle is increased to a second interval range, the ejection speed of the ink drops fluctuates, the quality of the image printed by the nozzle is slightly influenced, and the image is carefully distinguished and recognized to be discovered but is not obvious. When the firing frequency of the nozzle passes through the point P, and the firing frequency exceeds 29kHz and is in the third interval and the fourth interval, the fluctuation of the ejection speed of the ink drop is larger and larger, and the continuously accelerated ejected image has the effects of white lines, jumping, satellite dots or lines which are not straight and the like, so that the quality of the ejected image is greatly reduced.
Because the speed fluctuation of the third interval and the fourth interval is larger and larger, the speed is not increased continuously after the speed is accelerated to 29kHz in the printing process, and then the uniform speed once-through type ink-jet printing is carried out at the constant ignition frequency of 29 kHz. If an image of 600dpi resolution is printed,printing speed V of printer under condition of ignition frequency of 29kHz29kHz=29000Hz/600dpi × 2.54=122.8 cm/s. However, the higher the firing frequency, the faster the printing speed, and the higher the operating efficiency, such as the printing speed V of the printer at a firing frequency of 40kHz40kHz=40000Hz/600dpi × 2.54 ≈ 169cm/s, and the maximum theoretically achievable printing speed V of the printer can be reached when the maximum firing frequency of the head is 50kHz50kHz=50000Hz/600dpi×2.54≈212cm/s。
FIG. 2 is a schematic diagram showing the voltages applied during normal operation of the head, in which the waveform has a rise time Tr of 2.0us, a fall time Tf of 2.0us, a pulse duration Tw of 4.5us, and a voltage range of 17-19V. When the firing frequency of the nozzle is in the first interval and the second interval, the nozzle can eject images with high quality effect by using the driving pulse shown in fig. 2. However, when the driving pulse is continuously used, the ignition frequency is increased as the transmission speed of the printing medium is increased, and when the ignition frequency reaches the third interval and the fourth interval, a quality problem recognizable by naked eyes can be caused, and the printing speed reaches a bottleneck and cannot be increased continuously. Through trial and error, find the compensating pulse-B pulse and C pulse. When the ignition frequency exceeds 29kHz and is less than 40kHz, namely the ignition frequency is in a third interval, the FPGA (or software) of the circuit control board/the nozzle control board controls the nozzle to apply B pulse, as shown in figure 3, after the B pulse is used, the unstable fluctuation of the ink drop ejection speed in the third interval in the nozzle characteristic curve can be compensated, and an image with qualified quality and usability can be printed. When the ignition frequency exceeds 40kHz and is less than 50kHz, namely the ignition frequency is in a fourth interval, the FPGA (or software) of the circuit control board/the sprayer control board controls the sprayer to apply C pulses, as shown in figure 4, after the C pulses are used, unstable fluctuation of the ink drop ejection speed in the fourth interval in the sprayer characteristic curve can be compensated, and an image with quality reaching the standard and capable of being used is printed.
It should be noted that, since different inks also affect the printing effect, the compensation waveform of the present invention can also use pulses with other shapes, mainly adjusting the rising time Tr, the falling time Tf, the pulse duration Tw and the voltage range of the waveform, and is not limited to the waveform curve drawn in the drawing. The invention aims to protect a method for compensating voltage pulse in an unstable area aiming at the ignition characteristic of a spray head.
In addition, according to the principle, when the firing frequency is in the second interval, that is, when the firing frequency is greater than 22kHz and less than 29kHz, although an image with satisfactory quality can be printed, the quality is slightly different, such as a plurality of satellite spots and the like, at this time, the a' pulse shown in fig. 5 can be selected for driving, so that the inkjet effect is refined and is not more critical.
Example two
When the nozzle with the characteristics shown in fig. 1 is used, the problem of poor printing quality in the third interval and the fourth interval can be avoided by reducing the image printing resolution. Specifically, if the original resolution of the printed image is 600dpi, the image effect printed by the head at the start of acceleration is satisfactory, and the print quality is problematic after the firing frequency reaches 29kHz, i.e., P dots, then the printing speed V of the printer at 29kHz is set to be low29kHz=29000Hz/600dpi × 2.54=122.8 cm/s. When ink jet printing was started at 29kHz, P.sub.point, with a resolution of 400dpi, an image meeting the requirements could be printed. Similarly, the Q dot position at the firing frequency of 40kHz, the printing speed V of the printer40kHzAnd if the third interval is printed by 400dpi, the actually required ignition frequency of the image at the point Q is 169 cm/s/2.54 × 400dpi & 26.6kHz, and the actually required ignition frequency is in the second interval with stable waveform and can print qualified images. For example, when the print speed of the head is 43000Hz/600dpi × 2.54=182.0cm/s when printing an image with a resolution of 600dpi (in the fourth interval), but the actual firing frequency used after the resolution is reduced to 400dpi is 182.0cm/s ÷ 2.54 × 400dpi =28.7kHz, and the firing frequency is in the second interval in which the waveform is stable and a good image can be printed, the resolution reduction method can bypass the third interval and the fourth interval with large fluctuation, and a good image can be printed.
It should be noted that, after the printing resolution is reduced, the printed image may be slightly lighter in color, but it is still ensured that the user's needs can be met, and the specific reduction of the resolution is determined according to the actual situation.
EXAMPLE III
As shown in fig. 6, it is a characteristic curve of another nozzle during printing, and it can be seen from the curve that the ink drop ejection speed tends to be stable when the firing frequency of the nozzle is less than 10kHz, and this interval is defined as interval 1; when the ignition frequency is in the range of 10kHz to 16kHz, the fluctuation of the ink drop ejection speed is obvious, and the interval is defined as a 2 nd interval; the ink drop ejecting speed becomes stable after the ignition frequency is more than 16kHz until the maximum ignition frequency of the nozzle is 20kHz, and the section is defined as a 3 rd section.
In the process of accelerating the transmission of the printing medium, the ignition frequency is gradually increased, in the 1 st interval, because the ejection speed of the ink drops is basically stable, the printed image effect can be ensured, if the resolution of the image printed by the nozzle is 600dpi, the printing speed V of the printer at the end of the 1 st interval with the ignition frequency of 10kHz is ensured10kHz=10000Hz/600dpi × 2.54 ≈ 42.3 cm/s; in the 2 nd interval, because the jet speed of the ink droplet changes apparently, the image effect printed is also relatively poor, may appear the white line, jump, satellite point or line is not straight, etc. bad picture of quality, the printing speed V of the printer when the firing frequency is 16kHz at the end of the 2 nd interval16kHz=16000Hz/600dpi × 2.54 ≈ 67.7 cm/s; in the 3 rd interval, the ink drop jetting speed is stabilized, the printed image effect is improved, and theoretically, the printer can reach the maximum printing speed V when the nozzle can reach the maximum ignition frequency of 20kHz20kHz=20000Hz/600dpi×2.54≈84.6cm/s。
If the problem of poor quality effect of the ejected image in the interval 2 cannot be solved, the printing speed cannot be higher than the maximum ignition frequency in the interval 1, namely 10 kHz; or even if the ignition frequency is continuously increased to the 3 rd interval, stable printing is realized, but the situation that an image which does not meet the quality requirement is printed when the 2 nd interval passes cannot be avoided, so that the printing medium is wasted, and the subsequent cost is increased.
In the actual printing process, the 1 st interval uses E pulse as driving pulse, the quality of the printed image is good, after repeated tests, after the ignition frequency reaches 10kHz, namely the 2 nd interval is switched to F pulse for driving, the unstable condition of the ink drop ejection speed in the ignition frequency can be compensated, the image with good effect can be printed, until the ignition frequency reaches 16kHz, the ignition frequency enters the 3 rd interval, the driving pulse is switched again to use E pulse, and the whole process can print the image with high image quality.
If the E-pulse is used all the way without the switching pulse, compensation can also be made by changing the resolution, including increasing or decreasing the resolution. For example, the original printing resolution is 600dpi, and the printing speed V of the printer is at the firing frequency of 10kHz at the end M point of the 1 st interval10kHzAnd if the switching printing resolution is reduced to 480dpi at the moment of 10000Hz/600dpi × 2.54 ≈ 42.3cm/s, the actually required ignition frequency during printing at the M point is 42.3cm/s ÷ 2.54 × 480dpi ≈ 7.99kHz, and the ignition frequency is converted into the 1 st interval with stable waveform and capable of printing a qualified image. Printing speed V for N-dot printing of 600dpi image at end of 2 nd section16kHzIf the ignition frequency is switched to 720dpi and actually required for printing at an N point is 67.7 cm/s/2.54 × 480dpi and 19.2kHz, the ignition frequency is switched to the 3 rd interval in which the waveform is stable and a quality image can be printed. The printed image has the phenomenon of slight lightening or darkening, the visual effect of the image is not influenced, and if the bar code is printed, the scanning and the identification of the bar code are not influenced.
It should be noted that what kind of waveforms are specifically switched, or how much the printing resolution is raised/lowered, is selected according to different nozzles and different requirements according to experiments, and the method for compensating the instability of the ejection characteristics of the nozzles by switching the waveforms or changing the resolution is only protected in the present invention, and the specific manner is not limited.
