Multilayer paper having an improved combination of stiffness and smoothness, and the processes for producing such pa- per products are disclosed. The multilayer papers are formed using chemical pulp, with the outer layers comprised of coarser, stronger fibers and the inner layer of finer but weaker fibers that exhibit a higher compressibility than the fibers of the outer lay- ers. Such multilayer papers exhibit improved stiffness and strength from having the stronger fibers located in the outer layer, without loosing the preferable surface smoothness of the finer inner-layer fibers, whose smoothness characteristics are reflected in the final surface smoothness.
