Abstract (en)
This invention provides coated paper and paper board and methods of manufacturing these materials by implementing the benefits of impulse drying. The novel methods include providing a moist web of paper-making fibers and impulse drying this web at a temperature of at least about the glass transition temperature of the paper-making fibers to produce an impulse dried sheet having a Parker Print Smoothness of less than about 6.5 microns. Following impulse drying, the impulse dried sheet is surface coated to produce a coated sheet having improved physical properties.
