👉 Printing fluid, also known as inkjet or thermal ink, is a specialized liquid used in inkjet printers to transfer toner or liquid ink onto paper. It plays a crucial role in the printing process by providing the necessary viscosity and surface tension to ensure smooth ink flow through the printer's nozzles and onto the paper. For toner-based printers, the fluid is typically a dry powder that becomes a viscous liquid when heated by the printer's nozzles, allowing it to adhere to the paper. For liquid inkjet printers, the fluid is a water-soluble solution that carries the ink particles to the paper. The precise formulation and consistency of printing fluid are essential for achieving high-quality prints, consistent color reproduction, and reliable performance in the printing process.
