The ink is the "blood" of the inkjet printer. Ink PH value, viscosity, the number of suspended particles, drying time on the printing effect and the printer's inkjet head will have a greater impact. The original ink PH value is generally maintained at around 7, both neutral and moderate viscosity, ink water resistance, resistance to smear and light resistance (anti-fade) have been repeatedly tested. Compatible ink PH value are biased in acidic or alkaline, in contact with the air will form a trace of salt, combined with the drying time slightly longer than the original, so will make the graphics after the instability.
The influence of ink
The dell ink plays a decisive role in the accuracy, speed and quality of color inkjet printers. The effect of ink on the components of the printhead is particularly important, including ink cartridges, nozzle plates, ink flow channels and heaters. Ink characteristics include the color of the dye, the number of colors that can be produced (the full color gamut called color), the ability to resist water, the ability to resist light, and the performance of the printhead. In addition, the surface tension, speed and pH of the ink are the three main characteristics of the ink and play an important role in determining the characteristics of the printer.
The surface tension of the ink
The surface tension of the tn 660 ink affects many of the performance of the printer. Such as the wettability of all printhead components that affect ink contact, such as ink cartridges and ink flow channels. The surface tension and wettability also affect the back pressure maintained in the ink cartridge, and the back pressure also seriously affects the rate at which the ink is refilled with the ink after the jet is ejected. The refill time is a key indicator of the nozzle heating frequency, which directly affects the print speed. The ink surface tension also affects the ink dot diameter and ink drying time produced by a certain size of ink, which in turn determines the throughput of the printer. The shorter the drying time, the faster the print speed is.
The surface tension also affects the optical density of the ink droplets, which in turn affects the print quality. Finally, the surface tension affects the activation energy necessary to form the bubble core on the surface of the heater, and the activation can affect the design of the heater. The ink velocity strongly affects the geometric factors of the ink flow path, and the geometric factors affect the ink refilling time, which also affects the size of the ink droplets on the paper to form the ink dots, thus affecting the print quality.
