About Paper
Key important factors about paper.
Brightness is an attribute of visual perception in which a source appears to emit or reflect a given amount of light. It is a gauge of how well the lignin component of paper has been removed from the paper pulp and a means with which to measure the age of the paper. It is expressed as a percentage of the reflectance of blue light at a wavelength of 457 nm. The brightness of a piece of paper is typically expressed on a scale of 1 to 100 with 100 being the brightest. Papers with large amounts of residual lignin will have lower brightness.
Bulk is a term used to indicate the thickness of paper in relation to its weight.
The term “GSM” stands for “grams per square meter.” For this standard, the weight of various types of paper is measured from a sample sheet cut to one square meter in size. ... The first measurement refers to the length and width, while the second measurement refers to the weight and thickness.
Moisture is the amount of water present in the paper which is usually expressed as a percentage. Paper is made from a water suspension, or slurry, of fibres normally ranging in concentration or consistency from 0.5 to 1.0% solids. The thicker the slurry, the heavier will be the basis weight, or grammage, of the sheet of paper. Hence, the moisture content is important in calendaring, printing and converting.
Opacity is an attribute of how much light is kept away from passing through the sheet. It is an important parameter for printing paper and books.
Smoothness is an attribute of the paper’s surafce. It is important for writing as it affects the ease with which a pen can travel over the paper’s surface.
