Abstract

Changes of printing paper strength indices are considered depending on specific mass and internal structure of paper and stretching experimental results taken from lengthwise and transverse paper samples according to GOST 30436-96 requirements. The “effort-deformation” and mechanical strength indices of functions’ regression equations are obtained as well as optimal options of equation degrees are chosen for their use in calculations.
