Significance and Use
4.1 Nonvolatile content of printing inks is useful for specification acceptance between the producer and the user.
4.2 In order to obtain accurate results for heatset systems within the specified 3-h heating time, the specimen film thickness must be less than 100 g/m2, and the oven must have forced ventilation. Thickness of the specimen film is less critical for liquid ink systems.
1.1 These test methods cover the determination of weight content of nonvolatile matter in two types of printing inks.
1.2 Test Method A is applicable to heatset-type printing inks and resin solutions; solvents in such systems typically have initial boiling points in the range from 240 to 275°C (470 to 535°F) and vapor pressures less than 0.2 mm Hg.
1.3 Test Method B is applicable to liquid-type printing inks and vehicles based on aqueous or organic solvents that evaporate readily at ordinary room temperatures.
—Test Method A (for heatset systems) specifies a specimen film thickness that is much thinner than those produced by related test methods; one exception is Test Method B in Test Methods D1259, which is recommended as a referee test.
—Test Method B (for liquid ink systems) is similar to Test Method D2369 except that a solvent is not required for spreading the test specimen.
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 and health practices and determine the applicability of regulatory limitations prior to use.
