Abstract:
A method for obtaining and evaluating a white color shielding degree of a white color printed material includes the steps of: measuring an L* value of the white color printed material; obtaining an integrated value of transmittance of the white color printed material in a visible light region; and obtaining the white color shielding degree from the L* value and the integrated value.
