Abstract (en)

[origin: EP0174661A2] A method and apparatus to produce a relatively dense high quality paper suitable for multi-colour printing are provided. The paper web is super soft-calendered while at a moisture content of between about 15 to about 55% and the web is subsequently treated to further reduce its moisture content. This procedure prevents galvanizing of the sheet which normally would occur using prior art techniques.
