    • PROBLEM TO BE SOLVED: To easily and appropriately perform matching determination of printed color in adjustment of ink supply quantity in a print simulation method and device for a printing machine by simulating the adjustment of ink supply quantity for each ink supply zone and further faithfully displaying the result on a monitor screen. SOLUTION: The method includes a print pattern display step of converting data of a print pattern to a coloring state of the printing machine based on printing characteristics of the printing machine and displaying it as a simulated display pattern on the monitor screen; and a color correction step of simulating a density change of ink color corresponding to an ink film thickness (solid density) change by the adjustment of ink supply quantity for each ink supply zone of the printing machine to correct the coloring state of the simulated display pattern. In the color correction step, density change reducing processing is performed near a boundary between of each ink supply zone and an ink supply zone adjacent thereto in the simulated display pattern to reduce the density (ink film thickness) change at the boundary.
