This procedure may be used to determine how water will affect solid-fill color images produced by ink jet printers.

Four different test methods are outlined to simulate the most common ways that materials are exposed to water.

The method of water application may greatly affect the outcome of the test. While one or more of the test methods may be performed, to best qualify a product all four test methods should be used.

The drip and spray test are evaluated visually, while the submersion and rub tests can be evaluated visually and instrumentally.

Test results are useful for specification acceptance between producer and user, for quality control, and for research and product development.

1.1 This practice covers methods that can be used to determine the waterfastness of an image produced by an inkjet printer. Waterfastness is determined by the presence of ink transferred from a specific printed area to a non-printed area, or to neighboring printed areas of a different color.

1.2 This practice can be used to evaluate the waterfastness of the primary print colors (cyan, magenta, yellow and black), the secondary colors (red, blue and green) and composite black (cyan plus magenta plus yellow).
