ASTM D7189-12R20 - Standard Test Method for Relative Mileage of News Ink on Newsprint

1.1 This test method covers the laboratory procedure for determining the relative mileage of news inks on newsprint. The test method utilizes a proofing press, analytical balance and a reflection densitometer.

1.2 This test method is intended for black oil-based news inks that dry by penetration (that is, letterpress or web offset) and for which a suitable reference standard is available. With appropriate optical instrumentation, it is also applicable to colored news inks.

1.3 This test method may also be used to determine the relative ink receptivity of test newsprints versus a reference standard.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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.

1.6 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.
