Ink is the “blood” of the inkjet printer. The PH value, viscosity, suspended particle number, drying time and so on of the ink jet printer will have a great influence on the printing effect and the inkjet head of the printer. The PH value of the original ink is generally maintained at about 7, Both neutral and moderate viscosity, ink water resistance, smear resistance and light resistance (anti-fading) have been repeatedly tested. Compatible ink PH values are more acidic or alkaline, after contact with air will form trace salt, In addition, the drying time is a little longer than the original, so the spray will make the graphics unstable.
Ink plays a decisive role in the accuracy, speed, and quality of color printing by color inkjet printers. The effect of ink on all parts of the printing head is particularly important, including ink storage cartridges, nozzle plates, Ink flow channels, and heaters. Ink characteristics include the color of the dye, the number of colors that can be produced (known as color gamut, water resistance, light resistance, printing head performance, etc.). In addition, the surface tension of the ink, Speed, and PH are the three main characteristics of ink and play an important role in determining printer characteristics.
