Strength Problems (Troubleshooting Guide)
Strength (Low, Variable, Too High) Paper strength can be regarded as being a result of the strengths or individual fibers, plus the strengths of bonds between those fibers. Usually the bonds are weaker than the fibers themselves. That fact implies that it is worth paying a lot of attention to factors that affect inter-fiber bonding.
