Apparatus for measuring hardness of ultraviolet curing transformation agent comprising stain and method for the same

摘要

An apparatus for measuring hardness of an ultraviolet curing transformation agent comprising a stain of the present invention comprises a light source device for emitting beams including ultraviolet rays, an optical filter member through which the ultraviolet rays having a predetermined wavelength among the beams emitted from the light source device pass, and a measuring device for measuring electric conductivity of the ultraviolet curing transformation agent comprising the stain, provided at a location where the ultraviolet rays having the predetermined wavelength irradiate. Further, the measuring device comprises an electrode portion including electrodes on which the ultraviolet curing transformation agent is applied, and the electrodes are connected through a power supply and a measuring device for measuring the electric conductivity. Therefore, the measuring apparatus of the present invention can readily and rapidly determine the hardness of the UV curing transformation agent comprising a stain such as a pigment, corresponding to the printing condition.
