Definitions

  • the present invention relates to a roll printing paper which has a coating containing pigment and binder on both sides of a coating base paper containing mineral filler, recycled fibers and possibly wood pulp and / or cellulose.
  • the invention further relates to a method for producing the roll printing paper.

  • the prepared papers are then treated on a super calender. If only starch was applied, a considerable increase in tensile strength as well as a smaller and, depending on the amount of starch applied, a decrease in stiffness that was observed again was observed. The opacity, on the other hand, decreases considerably if the preparation applied consists only of starch.
  • composition of the coating base paper used in particular a possible proportion of recycled fibers, the filler content and the mass per unit area of the coating base paper are not disclosed.

  • the coated paper is said to have a whiteness of 61.8, while the coating base paper has only a whiteness of 50.7.
  • EP-A-0 377 983 relates to a further development of the proposal according to the abovementioned document, but additionally provides for a needle-shaped pigment in the coating to be applied by means of an air brush or a doctor blade device (blade coater).
  • the coat weight to be applied to a base paper containing 30% by weight of recycled fibers should be between 1 and 12 g / m 2 , preferably between 3 and 8 g / m 2 and the side to be printed on. In total, a surface mass of 60 g / m 2 should not be exceeded.
  • the usual pigments can be used as fillers for the base paper, their proportion is usually between 0.5 and 10% by weight, but is preferably even less than 0.5%.
  • a super calender and / or a machine smoothing unit is used for calendering.
  • the coating formulations given here for a paper to be printed in offset printing have a binder-pigment ratio of 0.5: 1 to 1: 1.

  • the fibrous entry of the coating base paper consists only of deinked recycled fibers.
  • the filler content and coating correspond to the embodiment specified above.
  • the filler is to be understood as the mineral pigments that are added to the fiber suspension during papermaking. No distinction is made between freshly added fillers and fillers which are fed into the paper production process together with fibrous materials recovered from waste paper.
