GB/T 22770-2008 "Printing technology — Determination of rheological properties of paste inks and vehicles using a falling rod viscometer" specifies a method for determining the rheological properties of paste inks and vehicles using a falling rod viscometer, and is applicable to the testing of rheological performance of related products. The principle involves characterizing the rheological properties of the sample by measuring the time taken for a falling rod of a specific mass to descend a certain distance within the sample. The testing requires instruments such as a falling rod viscometer, a constant-temperature water bath device, and a stopwatch. The operation is simple and fast, providing data support for ink production process control and printability evaluation.
