Abstract
The research presented in this paper is the result of a study on the dynamic and static viscoelastic properties of one-side
coated papers for the purpose of offset printing. During their formation and the technological processes of coating and
printing, paper substrates are exposed to various traction forces, which cause not only nonlinear time dependence, but
also a permanent irreversible deformation. Paper, which is basically a composite material, also demonstrates
viscoelastic properties. Viscoelastic materials characteristically adjust and respond to external forces, i.e. stresses and
strains, in the form of a continuous rearrangement of molecular, supramolecular and other hierarchical morphological
structures.
