PROBLEM TO BE SOLVED: To calculate the emitting quantity of ink in a moment at every ink dot by calculating the emitting quantity of ink on the basis of the concn. of an ink dot. ;SOLUTION: In such a state that the focus of a microscope 3 is matched with the arbitrary one of printed dot patterns and the magnification of the microscope and the intensity of a transmission light source 6 are properly set, the image of the dot patterns is taken in an image processor through a color CCD camera 5. A frame of a fixed size is applied to the image of the taken-in dots to be measured. The integrated brightness of the actually calculated dots to be measured by integrated brightness and the reversal of the calculated value is set to the absorbancy (density data) of the dots to be measured. Next, the ink emitting quantity of a nozzle is calculated in the state corresponding to the density of ink dots formed by the ink.;COPYRIGHT: (C)1997,JPO
