Tear strength is the force necessary to continue the tearing of paper from an initial cut. It is an important parameter for the pin feeding of sheets through the printer. If the tear strength is too low, the web can break in the printer. The tear strength is higher in the cross direction than in the machine direction of the paper. Tear strength, the force necessary to tear paper further
Tensile Strength
The tensile strength is a property which describes the general strength of any material. In the case of paper, it is the maximum force per unit width that can be applied to a sheet of paper before it breaks. The higher the tensile strength, the stronger the paper and the higher the speed at which the paper can be fed into a printing press. Tensile strength is much higher in the machine direction than in the cross direction. It depends to a large extent on the type of pulp and filler used. Tensile strength, the force at which paper breaks.
Transmission
Some of the light falling on the paper surface penetrates the paper and is emitted on the other side.
