Ink rheology testing service DrRheology

Ink rheology

Inks vary by by their constituent components as well as from batch to batch. From ink manufacture to finished article, the fluid can go through a large range of of deformation rates, as well as experiencing different kinds of flow. This makes understanding and controlling the rheology of inks a desirable subject.

DrRheology can support ink manufacturers and ink users by testing the ink, as well as calculating flow performance. The key tests offered below will allow product and process development, as well as supplying spot checks for QC.
