Abstract:

The long lifecycle, also known as durability and the permanence / invariability in the quality of papers and cardbords for graphic art, are today the basic requirements, imposed by printed art in terms of high quality parameters. These two factors are a manifestation, depending on different internal chemical-composition properties of the paper consistency and external influences of the ambience. Longevity and permanence are perceived as a function of aging and are actually observed at a later point in time. It is important to clarify that they are terms with different contents where „durability” is perceived as the ability of the paper or cardboard to resist the impact of wear during use, and the „permanence” is the possibility of product to remain chemically and physically stable for a long period of time.
