PROBLEM TO BE SOLVED: To provide a new method for evaluating a white color shielding degree, which evaluates a white color shielding degree, "the white color shielding degree" being newly defined as the definition of the whiteness of a white ink-printed material and being obtained from [(L value-α)/integrated value ×1,000] (hereinafter referred to as LS value (Lightness Shielding)) (α is a preliminarily set numerical value of 60-70), which is a numerical value relating to both [an L value] and [an integrated value of transmittance in a visible light region].;SOLUTION: The method for evaluating the white color shielding degree obtains and evaluates a white color shielding degree of a white color-printed material and includes the steps of measuring the L* value of the white color-printed material; obtaining the 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.;COPYRIGHT: (C)2011,JPO&INPIT
