Optimization analysis of the inkjet using the Taguchi method

Inkjet printers are effective tools for combining high resolution with acceptable velocity and low cost output. In this study, the incompressible Navier-Stokes equations were used to investigate the weight change of the inkjet droplets for the two-phase flow. For the ink color black, red and blue, for the nozzle inlet radius 0.02, 0.03 and 0.04mm, and for the inlet velocity 0.2, 0.4 and 0.6 m/s were taken. Taguchi analysis was performed, and it was seen that the most effective parameter on ink weight was the inlet velocity. It has been determined that the optimum conditions for weight maximization are black color, 0.02mm nozzle radius and 0.6 m/s inlet velocity. After determining the optimum conditions, droplet flow analysis was numerically carried out with the Comsol program to detect the change in different colored inks. It showed that the droplet fluid amount was greater and the time it took to reach the target area was shorter for inks with higher density and viscosity.
