👉 Ink fluid is the liquid component in ink that carries the pigment particles and binding agents to paper during printing or writing processes. It is typically a mixture of water, dyes, pigments, and sometimes additives that enhance ink performance. The fluidity of the ink fluid determines how easily it flows through printing mechanisms, such as inkjet heads or nozzles, and affects the quality of the printed image. Proper balance in the ink fluid composition ensures optimal viscosity, adhesion to paper, and color vibrancy.
