Meaning and use

5.1 The ability of the coating to resist printing is important because if the smoothness of the coating is changed through contact with another surface, especially a textured surface, its appearance will be adversely affected. Interior paint systems, especially gloss and semi-gloss on windowsills and other horizontal surfaces, often have objects such as flower POTS placed on them, which may tend to leave a lasting impression. This tendency of paint film “printing” is a function of coating hardness, pressure, temperature, humidity, and the duration of the object’s contact with the painted surface.

ASTM D2064-16 Standard Test Method for Printability of Architectural Coatings

Step 1: Scope

1.1 The test method includes an accelerated procedure for evaluating printability of architectural coatings. It differs from the printed resistance test method D2091 in that the latter relates to finishes under packaging, transportation, and storage conditions, while this test method relates to decorative coatings that experience random field pressure contact.

Note 1: Printing should not be confused with blocking, which is measured in test method D4946. The former involves the indentation of a surface, while the latter involves the bonding of two surfaces.

1.2 Values in inch-pounds shall be considered standard. The values given in parentheses are for reference only.

1.3 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
