ASTM D 7189 : 2012

1.1This 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.

1.2This 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.

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

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

1.5This test method 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 to determine the applicability of regulatory limitations prior to use.
