Measurement of cockling of fine paper samples using shadow moire method

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientific


Out-of-plane deformations such as waviness, fluting and cockling are typical defects for printing grades. Due to decreasing basis weights and increasing production speeds many mills are facing these problems. Quite often samples are evaluated visually since there are no standard methods for measuring these properties. In this paper a whole-field method – Shadow Moiré – was used to characterize the surface topography of paper samples. Measured sheet topography data was studied together with a large set of visually evaluated fine paper samples.
