Abstract
A method for managing the quality of an ink of an inkjet printer versus temperature resorting to the management of the viscosity of the ink versus temperature, the ink comprising a solvent or a mixture of solvents and the solvent or mixture of solvents representing at least 50% by mass of the total mass of the ink, wherein the viscosity of the ink at a temperature T is calculated from the following parameters: the viscosity of the ink at a single reference temperature T; the parameters K or Ln(K), and −E/R of equation (1) giving the viscosity of the solvent or of the mixture of solvents: Ln (viscosity of the solvent)=Ln(K)−E/RT (1) wherein E is the Arrhenius activation energy given in J/mol and R is the ideal gas constant.
