Printer: What is the difference between small characters or large characters?

Do we know the difference between large character inkjet printer and small character inkjet printer? , In the usual sense, it is understood that the font printed by the large-character inkjet printer is relatively large, and the font printed by the small-character inkjet printer is relatively small, so what are the differences between them? 1. The working principle is different. Let's first talk about the small character inkjet printer. The small character inkjet printer has a vertical downward nozzle. During the printing process, the ink droplets are charged by the inkjet machine, so that the ink droplets are charged. The principle of charged deflection of the ink droplets is then used to make the ink droplets be printed on the surface of the object according to a predetermined trajectory. However, due to the limitations of the function and working mode of the small character inkjet printer, the object to be printed and the nozzle must form a relative displacement during the inkjet printing process to complete the entire inkjet printing process. Large-character inkjet printers have a completely different working principle from small-character inkjet printers. The nozzle of the large-character inkjet printer will always 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, so as to complete 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 continuous electronic signals to control the micro solenoid valve on the nozzle to control the ink flow and print the specified pattern. 2. The printing effect is different. From the printing effect, the large-character inkjet printer has more outer packaging, the font is relatively large, and the small-character inkjet printer prints relatively small. 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. 3. Whether to add diluent or not. Since the small character inkjet printer is based on the principle of continuous ink supply, it is necessary to add diluent. The ink with standard viscosity will be in contact with the atmosphere during the circulation process, and the solvent in the ink will continue to volatilize, causing the viscosity of the ink to gradually increase , And too high viscosity will affect the charging of the ink dots, and directly affect the flying distance of the ink dots, and the printing effect will have errors. Therefore, when it detects that the ink viscosity is not normal, the machine automatically adds thinner 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 a thinner. 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 world in a relatively closed space. As long as the physical and chemical indicators of the ink are adjusted to The range set by the machine can be used normally. 4. The main purpose of large-character inkjet printers is mainly used to print the area code, date, batch number, etc. of the outer packaging of the product. It is widely used in food, beverage, medicine, chemical, cement and other industries. It can be printed on permeable surfaces (such as ordinary cardboard boxes, templates, textiles, etc.) and non-permeable surfaces (such as woven bags, silver mirrors, aluminum mirrors, glossy cardboard boxes, etc.). And the application of small characters is very extensive
