Detailed information:



General parameters of office paper:

• Density — weight per 1m2 of paper measured in grammes. The majority if office paper is produced with a density of 80 g/m2.

• Smoothness/roughness — usually expressed in units of Bendtsen smoothness. The optimal level of Bendtsen smoothness is a value between 150 and 250. Smoother paper passes more easily through printers and plotters and offers a higher quality of print image.

• Brightness / whiteness — affect the contrast between image and paper. ISO brightness is expressed as a percentage. Office paper normally has an ISO brightness value of about 90% or higher. CIE whiteness values are also expressed as percentages. Normal values for whiteness of office paper c between 130% and 160%.

• Surface smoothness and edge — the edges and surface of the paper should be clean to avoid poor adhesion and damage to office equipment.

• Rigidity — an indicator of resistance to bending in photocopying machine.

• Thickness of the sheet of paper is measured in microns. This indicator affects righty and transparency of the paper but to judge the paper by this indicator only would be wrong.

• Conductivity. If the value for conductivity of fax or printer paper is too high then the image quality may be poor and even fade.

The balance of these parameters determines the class to which the given paper relates.
