K & N method

a test for measuring the oil absorbency of paper

COMMENT: In the test (usually on smooth surfaced papers) K & N ink is applied to the paper with a spatula. Surplus ink is removed with an absorbent cloth after two minutes, and the colour density of the stain left on the paper is the measure of its absorbency. The darkness of the stain is measured with a spectrophotometer.
