ABSTRACT:
The printability characteristics of gloss calendered paper coated on one side only is improved by moistening the uncoated side of the paper prior to gloss calendering the paper. Enough liquid must be applied to the uncoated side to raise the overall moisture content to at last about 8.5% and preferably to about 10% or more. The paper is gloss calendered while still wet and before appreciable amounts of the added liquid can migrate to the coated side of the paper. Thus a localized zone of high moisture content is provided at the uncoated side of the paper during the calendering. Under such conditions the gloss calendering produces a paper whose printability characteristics, especially its print smoothness, are better than conventional gloss calendered paper and, under preferred operating conditions, approach or equal those of conventional supercalendered paper. The ability to produce paper of supercalendered printing quality on the less expensive, easier to operate gloss calender is an important advantage, especially since the gloss calenders are normally on line with the coating equipment in paper-making plants while supercalenders are not.
