Standard Test Method for Measurement of Comparative Legibility by Means of Polarizing Filter Instrumentation

Importancia y uso:

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

5.2 Previous research3 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.

5.3 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
