The EST- 12 instruments allows to characterize the surface properties of paper board by recording the
Dynamic Properties of liquid absorption from the moment of liquid contact, it can measure the absorbility
of the paper with the liquids of the lowest to medium viscosity, as well as printability, glue Ability &
suitability for coated paper board with test liquids like water, foundation solutions, mineral Oil, gravure inks,
flexographic printing inks, inkjet inks in offset, Gravure printing inks, etc. From EST – 12 three results can be
1) It describes the roughness & porosity of the paper.
2) Describe the wet ability of a paper.
3) Describes the water absorption capacity of the paper.
