<P>PROBLEM TO BE SOLVED: To provide a method for measuring an ink emulsification ratio in a printer of various type printing inks from an India ink which contains a carbon and in which a dampening water is emulsified by utilizing an infrared ray absorption an to provide a controller for measuring using the same. <P>SOLUTION: The method for measuring the ink emulsification ratio in the printer comprises the step of setting a value E obtained based on reflecting ray amount obtained by irradiating an ink film of a printer ink supply roll surface with infrared rays W, M and L, wherein W is the infrared ray in an infrared ray wavelength showing an absorbance peak to the water, M is the infrared ray showing small absorbance to the water and the ink, and L is the infrared ray in an infrared ray wavelength range showing an absorbance peak to the ink, to an ink emulsification ratio of the ink film. <P>COPYRIGHT: (C)2003,JPO |
