DIMENSIONAL STABILITY (Read more in article Aspects of Dimensional Stability, below)

SHEET SHRINKAGE IN DRYING

Shrinkage is perhaps the most important process effect on the mechanical properties of paper. Recently, Wahlstrom and Fellers showed that tensile stiffness, tensile strength, compressive strength and breaking strain are very closely correlate with sheet shrinkage or wet straining. A most likely explanation is that shrinkage affects micro-compressions, which in turn affects fiber properties, which affect sheet properties.  Read more at "Effects of Paper Shrinkage" and "Property Relationships", below.

XEROGRAPHIC (copy) PAPER

Paper qualities important in xerographic papers include stiffness, smoothness, electrical resistivity, friction coefficient, curl, moisture, sheet flatness, millwork, porosity and composition.  The usual basis weight of xerographic paper is 20 pounds (17" x 22" 500 sheets) or 75 grams/sq. meter. Good manufacturing control should keep weight within 0.5-0.75 pounds of nominal 99% of the time.  The choice of a caliper specification depends on factors such as the type of fuser roll used in the copy machine. There may be no single set of paper properties that are optimum for all xerographic machines (including ‘laser’ printers). Read more at Summary of Xerographic Paper Properties, below.
