Claim Text:
1. An inkjet printing apparatus for discharging ink droplets and an overcoating agent, the apparatus comprising: a printing head discharging the ink droplets; an overcoating head discharging the overcoating agent; and a controller operating the printing head and the overcoating head to perform printing to a print medium, the controller operating in an inspecting discharge mode forming an inspecting region at a printing rate in the print medium relative to a given area higher than the maximum of a printing rate of a normal discharge mode for confirming a discharge state of the overcoating agent, the maximum of the printing rate of the normal discharge mode in the print medium relative to a given area being less than 100% for the printing to the print medium, and in the inspecting discharge mode, the controller operating the printing head to form the inspecting region on the print medium, and operating the overcoating head to discharge the overcoating agent onto the inspecting region so as to produce shift linearly in a direction orthogonal to a transportation direction of the print medium and in the transportation direction, whereby an overcoating inspecting chart is formed.
