It results from the release of stresses that are introduced into the sheet during manufacture and subsequent use.

A poorly formed sheet will have more weak and thin or thick spots.Thus, such tests as brightness compressibility Standard Freeness (ml opacity and stretch will continue to be reported in the dame units.

Best recommendations

However, the brightness values of the pulps and pigments going into the paper provide an excellent measure of the maximum whiteness that can be achieved with proper tinting.The Basis weight of paper is the weight per unit area.
