Significance and Use
This test method is used as a manufacturing or laboratory process control tool by providing a visual comparison of the ability to resist solvent break-through against an established control. The test method is designed to indicate a potential problem caused by an undercured condition but does not identify what caused the condition.
This test method does not duplicate the conditions on a printing press but does provide a means to determine whether the test sample meets specifications as agreed upon between supplier and customer.
1.1 This test method describes the procedure for evaluating the relative cure of printed energy-cured (ultraviolet or electron beam) ink or coating by a mechanical solvent rub test using a motorized Crockmeter.
1.2 This test method is applicable to laboratory and production prints on any flat substrate that is no thicker than 3 mm (0.125 in.), durable enough to withstand the test conditions, and for which a control (reference) sample is available.
1.3 This test method applies to comparisons between energy-cured inks and coatings of the same chemistry and film weight and should not be used to compare different ink or coating chemistries or various applied film weights without first establishing process performance.
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 to determine the applicability of regulatory limitations prior to use.
