high-resolutioninkjet printerAlso known as a high-resolution inkjet printer, its spray resolution exceeds 200 DPI. Small character inkjet printer is a common continuous inkjet printer and an ink inkjet printer that uses non-contact inkjet. The differences between the two are as follows:

different working principles

On the integrated nozzle of the piezoelectric high-resolution inkjet printer, 128 or more piezoelectric crystals respectively control multiple spray holes on the nozzle plate. Through processing by the CPU, a series of electrical signals are output to each piezoelectric crystal through the drive plate. The piezoelectric crystal deforms, so that ink is ejected from the nozzle and falls on the surface of the moving object to form a dot matrix, thereby forming words, numbers or graphics.

The nozzle of the thermal foaming high-resolution inkjet printer uses semiconductor thin film technology. It uses laser processing and high-precision deep technology to form multiple spray holes with a diameter of about 50 μ m. These spray holes are arranged in a high density. The ink is electrified and heated through a thin film resistor., causing the ink to produce countless tiny bubbles, which gather into large bubbles and expand at a very fast speed, forcing ink droplets to be ejected from the nozzle; when there is no voltage to the resistor, heating is stopped, and no ink droplets are ejected.

The working principle of the small character inkjet printer is that under the action of pressure, ink enters the spray chamber. A crystal oscillator is installed in the spray chamber. Through vibration, the ink is ejected from a nozzle with a very small aperture (generally 60 microns) to form a fixed interval. Through CPU processing and phase tracking, some ink dots on the charging electrode are charged with different cores. After passing through a high-voltage magnetic field of several thousand volts, they will undergo different deviations, fly out of the nozzle and land on the surface of the moving product, forming a dot matrix, thereby forming text. Numbers or graphics.

Different application fields

Small character inkjet printers are widely used in food, beverage, daily necessities, medicine, building materials, pipe industry, machinery, electronics, wire, cable, packaging and other industries. The scope of use includes spray printing of packaging production batches, spray printing of cosmetics production dates, spray printing of cards, spray printing of carton characters, spray printing of pattern logos, spray printing of some QR codes and barcodes, etc.

High-resolution inkjet printers are widely used in food, medicine, daily chemical, label spray printing, card printing, packaging and printing, medical, electronics, hardware and other industries. Because the resolution of high-resolution inkjet printers is higher than that of small characters, it is suitable for use. For applications in fields such as one object, one code, anti-counterfeiting traceability, the recognition rate can reach 100%.

Some other differences

The distance between the nozzle of a high-resolution inkjet printer and the surface of the printed object is usually 3 - 10 mm. If you code on a concave surface, the printing distance may be too long and the printed words are unclear. The printing distance of a small character inkjet printer can reach 5 - 6 cm; high-resolution inkjet printers generally have no limit on the number of rows, as long as the height does not exceed the printing height, while small-character inkjet printers can usually only print 3 lines at most; depending on the principle of the printer, the high-resolution drying time is slightly longer than the drying time of the latter; The speed of high-resolution is usually 0 - 100 m/minute, while the speed of the latter can reach as fast as 200 m/minute; since the high-resolution inkjet printer is relatively worry-free in maintenance, only the nozzle needs to be cleaned regularly, while the small-character inkjet printer needs to be turned on and run regularly; in addition, the ink of the small-character inkjet printer needs to be added with a thinner and is volatile.
