<p><P>PROBLEM TO BE SOLVED: To enable end point determination in the aging process without lowering ink characteristics, such as the degree of jet-blackness in a composition for a printing ink including carbon black, namely, proper determination whether the surface of a CB particle is wetted by a vehicle. <P>SOLUTION: A method of evaluating a component for a printing ink includes the steps of distributed processing a composition for a printing ink including carbon black, thereafter measuring a capacitance of the composition of a printing ink during aging, and calculating the rate of a change of the measured value, and a method of manufacturing the printing ink including the evaluating method is also provided. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
