Colleagues in the digital printing field have their own set of understandings and respected brands for the Thermal Transfer Print Head, an important component of printing equipment, and Tsc Barcode Printer Head also have certain requirements for the characteristics of the printhead from different perspectives. Some focus on cost, some focus on lifespan, some focus on ink adaptation range, and some focus on after-sales. Of course, in the final analysis, printing quality is the indicator that everyone focuses on, and it is also the product feature that various thermal Printhead Compatible manufacturers have been working on improving. As a latecomer to the inkjet printing market, Kyocera inkjet printheads stand on the shoulders of giants. After summarizing the pain points and needs of the existing market, Kyocera makes full use of Kyocera's deep understanding of ceramic materials and organically combines its expertise in electrical, With the technology and experience accumulated in the audio and mechanical fields, we have developed a piezoelectric inkjet print head based on monolithic piezoelectric ceramics. Since entering the market, Kyocera print heads have high printing width, high ignition frequency, and high precision. The printing quality has received widespread attention and recognition from the market. So where is the technical source of the high printing quality of Kyocera Tsc Barcode Printer Heads, or "Kyocera inkjet print heads, what do I talk about when I talk about image quality?"
1. Increase the discharge speed. One of the key factors affecting the printing quality is the accuracy and stability of the ink droplet landing point. Regarding the placement accuracy of ink droplets, it itself will also be affected by many factors, such as the processing accuracy of the nozzle hole, the uniformity of inductance of the piezoelectric ceramics, the stability of the ink temperature, and the printing spacing. However, in addition to the above factors, Except for temperature and printing spacing, all of them cannot be changed after the nozzle is produced, which means it mainly depends on the manufacturing process and processing accuracy. So when mass-produced nozzles are delivered to users, how to ensure that the printing accuracy of each nozzle is reliable. First of all, in the processing stage, Kyocera has passed the optimization and quality inspection of flow paths and processing techniques to ensure that the factory nozzles are shipped with high standards. However, the physical processing technology used in the production of nozzles is not photolithography after all, so there will be slight differences within the allowable tolerance range among the thousands of nozzle holes in a nozzle. Such differences also produce ink ejected from different nozzle holes. The flying speed of the drops is poor. The intuitive effect produced by this difference is that when printing a straight line perpendicular to the relative movement direction, slight fluctuations will be found after the straight line is enlarged. Usually, this kind of fluctuation can only be detected by the naked eye when it is 10~20c away from the printing screen. However, as an industrial-grade printhead, Kyocera has developed countermeasures to improve this small difference. Through the matching of high-performance piezoelectric sheets and waveforms, the initial velocity of ink droplets when they are ejected can be increased as much as possible while the ink droplets are intact. , using the high flight speed of ink droplets to compensate for the small individual differences between nozzles.
2. When talking about image quality, one word that is often used to improve image quality is "clean". So what is the fundamental difference between a "clean" picture and a slightly "dirty" picture? When it comes to a "dirty" picture, colleagues in the industry will immediately respond with "floating ink (scattered dots), miscellaneous dots (satellite dots), and smearing." On the contrary, when the picture is "clean", there is only one standard, ink dripping. The dots are round, the edges are clean, and there is not a single ink dot in the blank space of the picture. Colleagues who have an in-depth understanding of piezoelectric inkjet printheads all know that the ejection of each ink droplet is the result of acoustic resonance generated by the deformation of the piezoelectric sheet. The resonance of sound waves is the power source of inkjet, but if the residual sound waves are not properly handled, it will affect the formation of ink droplets. Through the simulation of flow paths and fluids, Kyocera emphasized the dual control of sound wave transmission and suppression in the flow path design during the research and development stage. Based on the reasonable flow path design and in conjunction with Kyocera's waveform debugging, Kyocera achieved the realization of each droplet The amount of ink can be reduced to one drop.
