    Significance and Use

    This test method assists in evaluating the effect of layout, typeface, type size, color, and background on the legibility of printed matter.

    Previous research has shown that results are more significantly impacted by subject age than any other effect. Older subjects tend to require more light when using this instrument. Because subjects age at different rates as a result of lifestyle and genetics, variability of data tends to increase with increasing age. This test method was developed using subjects of ages 19 to 28 years. It is advised that subjects age 19 to 28 be used in cases where variability needs to be kept to a minimum.

    Testers can compare legibility between various groups of subjects (by age, light intensity, distance, vision characteristics of the subjects) and one against other label configurations within groups of subjects

    1. Scope

    1.1 This test method provides an objective means to comparatively measure the ease of reading printed matter for use in package labeling.

    1.2 This test method is not intended to quantify the legibility of a printed item against a standard but to compare its legibility against other items.

    1.3 This test method uses human subjects to view printed matter mounted in a specialized instrument.

    1.4 The user of this test method must be aware that results may differ from one age group of subjects to another.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
