Copy paper
Under copying paper refers to wood-free , uncoated paper , which in standard formats from A4 or A3 particular in machines, the so-called small-size sheeters , is cut.
The papers have been specially developed for use in color or black-and-white copiers and, in addition to good absorption and anchoring of the copier color ( toner ), must also have good running properties ( printability ) on the pressure rollers - even during brief heating by the copier . The printability essentially depends on the density and size of the paper fibers and the paper thickness. Another printability factor is wettability, which provides information about the extent to which the selected paper type is suitable for printing with, for example, printer ink.
Copy papers are made from recycled fibers (secondary fibers ) as well as from cellulose fibers or wood pulp fibers (primary fibers).
Modern copier papers are already made in three layers by special paper machines in order to give the product specific quality properties such as improved printability and have an aging resistance of over 200 years.
