1.1 这些测试方法包括通过目视或仪器评估手动或自动混合制备的色调来确定糊状油墨分散体的相对着色强度的程序。 1.2 这些试验方法适用于糊状印刷油墨、冲洗颜料和其他颜料分散体，这些颜料分散体在普通室内条件下基本不挥发，并且有相同着色和稠度的湿参考标准。如果选择适当的染色基质，它们适用于任何颜色的分散体，包括黑色和白色。 注1: 着色强度的仪器程序原则上与试验方法中所述的程序类似 D387页 , D2745 , D4838 和 D6531 . 1.3 以国际单位制表示的数值应视为标准。 括号中给出的值仅供参考。 1.4 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、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 着色强度是油墨分散体的一个基本特性。 虽然湿缩印和着色的测试结果不能保证干印刷油墨膜的等效性，但它们为既定配方的质量保证、测量相对分散度以及估计不同批次、来源或等级的着色剂的颜色值提供了有用的参数。

1.1 These test methods cover procedures for determining the relative tinting strength of paste-type printing ink dispersions by visual or instrumental evaluation of tints prepared by manual or automated mixing. 1.2 These test methods are applicable to paste-type printing inks, flushed pigments, and other pigment dispersions that are essentially nonvolatile under ordinary room conditions and for which there is a wet reference standard of the same pigmentation and consistency. With proper choice of tinting base, they are applicable to dispersions of any color, including black and white. Note 1: The instrumental procedures for tinting strength are similar in principle to those described in Test Methods D387 , D2745 , D4838 , and D6531 . 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Tinting strength is an essential property of printing ink dispersions. Although test results on wet drawdowns and tints do not guarantee equivalency of dry printed ink films, they provide useful parameters for quality assurance of established formulations, gaging relative degree of dispersion, and estimating the color value of colorants from different batches, sources, or grades.
