A. Viscosity and surface tension: viscosity is the resistance of liquid flow, surface tension of liquid

It is related to whether the ink can be droplets; in general,HP Design Jet Water Based Ink require low viscosity and high surface tension to ensure good fluidity and droplet morphology;

B. PH value: It is the concept of pH. The stronger the acidity of the solution, the lower the PH value. Conversely, the stronger the alkali of the solution, the higher the PH value. In order to prevent the ink from corroding the print head, the PH value is generally between 7 and 12. , usually between 7-8, based on neutral;

C. Conductivity: In the Galaxy Eco Solvent Printer Ink, the conductivity value is a measure of the salt content.

In general, the salt content does not exceed 0.5% to avoid crystallization and electrochemical corrosion at the nozzle;

D. Wetting and Dispersing Agent: It is a kind of surface active. Its function is to improve the physical properties of the ink surface and enhance the affinity and wettability of the ink and the sponge. Therefore, the ink which is generally stored and transmitted through the sponge contains a dispersing agent.
