Abstract

The effect of alkaline internal sizing in improving paper smoothness and ink gloss in waterbased rotogravure printing was investigated. Papers were internally sized with alkyl ketene dimer (AKD) under alkaline conditions from slack-sized to hard-sized. Papers were printed with waterbased inks on a web gravure press. A major problem with waterbased inks is increased surface roughening of paper and a low ink gloss. Temporal surface roughening was reduced by increased AKD internal sizing with a concomitant significant increase of up to 400% in ink gloss. Surface properties were correlated with print quality. The print quality improved with increased hydrophobicity of the papers.
