Introduction to high resolution/thermal foam inkjet printer

How much do you know about high-resolution/thermal foam inkjet printers? Do you know what an inkjet printer is? What is a high-resolution inkjet printer? What is a thermal foam inkjet printer? What are the connections between them, and what is their working principle? What are their characteristics? What should we pay attention to in the process of use? So today’s editor will give you a talk about relevant technical knowledge for your reference.

First of all, what is ? In fact, it can also be understood from the literal meaning that the print head of the brand inkjet printer is usually used, which is usually installed and applied on the thermal foaming high-resolution inkjet printer. The thermal bubble inkjet technology mainly uses semiconductor thin film nozzles, and uses laser processing and high-precision coating technology to form multiple nozzle holes with a diameter of about 50 microns. These nozzles are arranged in a high density. After receiving the heating signal, the current is used to heat the ink to about 260°C in a very short time. The local ink is heated to form bubbles and expand to eject the ink. The characteristics of high-resolution inkjet printers: due to the high temperature, the nozzle material is easy to rust, so the life of this type of nozzle is relatively short. Most of the nozzles and ink cartridges are integrated, and they are integrally discarded ink cartridge nozzles after use.

Next, what is a high-resolution inkjet printer? High-resolution cij printers are also called high-resolution cij printers. The simple understanding is that the printing resolution exceeds 200DPI. There are two common nozzles: British Xaar nozzle high-resolution inkjet printer and nozzle high-resolution inkjet printer . Finally, let’s talk about what is a thermal foam printer? Thermal foaming is actually another name for high-resolution cij printers. It is mainly based on its foaming working principle, which generally refers to the bubble jet printing technology of high-resolution nozzles. From the definition of the above three terms, it can be concluded that the high-resolution inkjet printer is equal to the thermal foam inkjet printer and also the high-resolution inkjet printer.

The working principle of the high-resolution inkjet printer:

Speaking of the working principle of high-resolution, there are mainly two types of piezoelectric inkjet printing and bubble inkjet printing. The piezoelectric high-resolution cij printer The principle of printer printing: the nozzle plate of special material is used to precisely drill the 35 micron straight nozzle hole with a laser. The common one is 128 holes, and it is attached to a piezoelectric material milled multi-channel ink cartridge holder. Each shared wall of the clip body has lead electrodes. When a certain voltage is applied to the electrode, the piezoelectric material sharing wall deforms radially under the action of the electric field, forming a radial shear force to push out the ink. After the electric field disappears, the deformation recovers, and the negative pressure generated during the recovery process fills the ink back. Prepare for the next jet away. The font symbols that need to be printed are parsed into corresponding 0/1 level signals through software, and the start and stop of the corresponding nozzle PZT electrode is controlled by high frequency; the object to be sprayed moves in front of the nozzle to form the corresponding text or content on the surface of the object. Pattern logo.

What we need to pay attention to during use: When selecting and using high-resolution inkjet printers, we must pay special attention to the selection and application of ink, because high-resolution The core component of the inkjet printer is the nozzle. The maintenance of the nozzle is directly related to its service life, the effect of printing, and the stability of the nozzle.

Finally, the editor will summarize some of our usual Several common inks in use: quick-drying inks, oil-based inks, water-based inks, UV inks, etc., of course, ultimately will be recommended and selected according to the customer's products and the production and processing environment, technological differences and customer needs .
