The difference between large-character inkjet printers and small-character inkjet printers that we know about is usually understood as the relative impedance of fonts printed by large-character inkjet printers, while small-character inkjet printers have relatively small fonts. , So today I will give you an overview of the difference between them.
1. The working principle is different.
Let’s first talk about small character inkjet printers. The small character inkjet printer has a vertically downward nozzle. During the printing process, the ink droplets are charged by the inkjet machine to make the ink droplets carry droplets. Reuse ink. However, due to the limitations of the function and working method of the small character inkjet printer, the object to be printed and the nozzle must form a relative displacement during the printing process to complete the entire printing process. The small character inkjet printer is a nozzle. And it is detachable.
The large character inkjet printer has a completely different working principle from the small character inkjet printer. The nozzle of the large-character inkjet printer will always eject ink, but the valve design will be adopted in the front stage, and the effect of inkjet or stop can be achieved through the opening and closing of the valve, thereby achieving the printing target. When the printing job starts to run, the computer will analyze and calculate the pattern, convert it into instructions, and directly output a continuous electronic signal to control the micro solenoid valve on the nozzle to control the ink flow and print the specified pattern. A row of nozzles of the large character inkjet printer cannot be disassembled at will.
2, the printing effect is different
From the point of view of the printing effect, the large-character inkjet printer has more outer packaging, the font is relatively large, and the small-character inkjet printer prints smaller. Small-character inkjet printers have higher printing accuracy and tend to be physical characters. Relatively speaking, the characters printed by large-character inkjet printers are mainly composed of dots. Large character inkjet printers can print large characters over 10mm with penetrating ink dots. Small character inkjet printers can print characters from 1mm-15mm, and the ink dot diameter is less than 1mm.
3. Whether to add replacement agent
Because the small character inkjet printer is based on the principle of continuous ink supply, it is necessary to add a replacement agent. The standard viscosity ink is in contact with the atmosphere during the circulation process, and the solvent in the ink continues to volatilize, resulting in a gradual increase in ink viscosity. Therefore, when the ink viscosity is detected to be abnormal, the machine will automatically add a substitute agent to ensure that the ink in the mixing tank maintains a standard viscosity value to ensure print quality. The large-character inkjet printer ink does not need to add replacement agent. The large-character ink is based on the principle of ink supply on demand. The viscosity of the ink will not be affected by the outside in a relatively closed space. As long as the specific physical and chemical indicators of the ink are adjusted to the machine The set range can be used normally.
4. Cost budget
Big character inkjet printers and small character inkjet printers are ink-type inkjet coding equipment, which can print dot matrix fonts and variable data identification information such as: numbers, dates, Chinese and English, serial numbers, batch numbers, LOGO, patterns, etc., and the printing speed is very fast, the alignment of the printing function can be adjusted, the font size, etc., the variability of the printing content can be adjusted simultaneously.
The difference between the two is that the large-character inkjet printer does not supply ink successively, but replaces the on-demand ink supply system, so the entire ink supply system is necessarily simpler than that of the small-character inkjet printer a lot of. The continuous ink supply system and system of small character inkjet printers are more complicated but save more consumables, thereby reducing production costs.
