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).

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 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.
