Significance and Use
5.1 This test method has found acceptance in the lithographic ink industry in predicting rheological behavior of a vehicle under press conditions caused by extrusion, shear-thinning rollers and dot gain recovery.
1.1 This test method covers the procedure for determining the viscoelastic properties of printing ink vehicles by measuring the G', G”, and tan delta using a controlled strain cone and plate oscillatory rheometer.
1.3 This test method is not intended for systems that are volatile at procedure temperatures as evaporation may occur effectively changing the percent solids before testing is finished and significantly altering the rheology.
