| abstract |
The invention relates to a method for the production of single- or multiple-coated paper and/or cardboard, with the exception of photographic paper and self-adhesive labelling paper, which are particularly suitable for printing, packaging and lettering. The substrate such as, for example, raw paper or cardboard, is singly- or multiply-coated with a free-falling liquid curtain, whereby the coating liquid particularly has an elongational viscosity between 1 and 1000 Pa.s at a Hencky strain rate between 1 and 15. |
