Water Resistant: The dyestuff ink particle is readily soluble in water and will bleed onto the paper, the pigment ink will bond itself to the paper fiber once it settles, it is not soluble in water. Light Resistant: The size of uni super ink particle is bigger than dyestuff ink. Hence its surface is less affected and the color remains vivid. Time resistance: differences between the structures of molecules. Due to sunlight and wind, the molecules of dye ink get broken but it is difficult to break uni super ink.
