| description | To provide a printed result prediction method and a printed result prediction system in an inkjet printer.SOLUTION: A printed result prediction method in a printing device that forms a plurality of ink dots by making ink droplets impact on a printing medium includes: a step of predicting ink droplet-impacting positions on the printing medium; a step of predicting a film thickness distribution of ink droplets on the printing medium on the basis of shapes of the ink droplets impacting on the predicted impacting positions; and a spectral reflection factor predicting step of predicting a distribution of spectral reflection factor of the ink droplets on the printing medium on the basis of unit spectral transmittance per unit thickness of the ink droplets on the printing medium, the film thickness distribution, and reflection characteristics of light from the printing medium. The step of predicting a film thickness distribution, when the plurality of ink droplets impacting on the predicted impacting positions interfere with each other, predicts shapes of the ink dots on the printing medium on the basis of dot diameters of the ink droplets, impact distances of the ink droplets and difference in discharge time of the plurality of ink droplets, and then predicts the film thickness distribution on the basis of the predicted result.SELECTED DRAWING: Figure 1
