Rotogravure Printability Aspects

New paper testing methods, partly using modern image analysis techniques, are applied in order to allow deeper understanding of the physical phenomenons influencing rotogravure printing results. Penetration phenomena of rotogravure inks into paper structure, z-directional deformation behaviour and surface characteristics are studied and new measurement techniques are developed. Image analysis techniques were also used to allow an objective evaluation of print quality. Using multivariate statistical techniques it was shown that penetration phenomena together with surface roughness and z-directional compressibility are to a large degree responsible for rotogravure printability results. not assigned GG: Unternehmen der dt.
