Standard Test Method for Relative Setting of Heatset Printing Inks by the Sinvatrol Tester

SCOPE
1.1 This test method describes the procedure for determining the relative setting speed of heatset inks using a specific tester.  
1.2 this test method is applicable to printing inks intended to be dried by the application of heat and for which a suitable reference standard is available.  
1.3 Although heatset inks are normally printed by the offset process, this test method specifies the direct letterpress mode because the higher ink film thicknesses obtained tend to amplify subtle differences in ink setting speed.  
1.4 This tester reads temperature and belt speed in nonmetric terms; therefore, instrument settings in this test method are stated first in U.S. Customary Units (inch-pound units of measurements). 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.
