1.1 本试验方法涵盖了评估建筑涂料耐印性的加速程序。它不同于打印电阻测试方法 D2091 因为后者涉及包装、运输和仓储条件下的油漆饰面，而本试验方法涉及经历随机现场压力接触的装饰涂层。 注1: 印刷不应与分块混淆，分块是在测试方法中测量的 D4946 . 前者涉及表面的压痕，后者涉及两个表面的粘合。 1. 2. 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 涂层抵抗印刷的能力很重要，因为如果涂层膜的平滑度因与另一表面（尤其是具有纹理的表面）的接触而改变，则其外观会受到不利影响。 内部油漆系统，尤其是窗台和其他水平表面上的光泽和半光泽，通常会在其上放置诸如花盆之类的物体，这些物体可能会留下永久的印象。漆膜“打印”的趋势是涂层硬度、压力、温度、湿度以及物体与涂漆表面接触的持续时间的函数。

1.1 This test method covers an accelerated procedure for evaluating the print resistance of architectural paints. It differs from print resistance Test Method D2091 in that the latter is concerned with lacquer finishes under packaging, shipping, and warehousing conditions, whereas this test method is concerned with decorative coatings undergoing random on-site pressure contact. Note 1: Printing should not be confused with blocking, which is measured in Test Method D4946 . The former relates to the indentation of a surface, and the latter, the sticking together of two surfaces. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. ====== Significance And Use ====== 5.1 The ability of a coating to resist printing is important because its appearance is adversely affected if the smoothness of the coating film is altered by contact with another surface, particularly one with a texture. Interior paint systems, particularly gloss and semigloss on window sills and other horizontal surfaces, often have objects such as flower pots placed on them that may tend to leave a permanent impression. This tendency for a paint film to “print” is a function of the hardness of the coating, the pressure, temperature, humidity, and the duration of time that the object is in contact with the painted surface.
