Pigments serve as fillers in order to increase whiteness and opacity (impermeability to light) and to make the paper more compact and dense. We prepare a suspension of Kaolin (white clay, see image) by mixing it with water and chemicals. Together with further additives the finished mixture is then sent to the colour shop and from there to the coating machine.Every kind of paper requires special adjustments to the coating machine, which are monitored during the production process. The colour evenly distributed on the rollers is spread on the raw paper by a metal blade and the excess colour is removed. Infrared heaters, hot air and steam heated cylinders dry the wet coating.
Elegant surfaces: glossy, half matt, or matt
In another machine, the supercalender, pressure, friction, dampness and warmth gives the paper its gloss and smoothness. In it, it passes across several steel and hard paper rolls rotating at different speeds and counter to each other. The half matt paper qualities are given a special matt satin finish in which the paper surface is compressed but not smoothed. It gives the print colours a particularly vivid and brilliant appearance while the unprinted area of the paper later appears matt and free of reflections.
Premium paper, ready for dispatch
After cutting to various roll widths, the narrow rolls are either sent to roll dispatch or to the sorting transverse cutting machine where they are cut into sheets of various formats. The quality of every paper shipment is checked before delivery. Packed in convenient quantities or on pallets, the finished Scheufelen premium paper then leaves our works.
