Optical and Colour Stability of Graphic Paperboards and Laboratory Prints

Paper and board as carriers of written cultural heritage remain important materials, so now days as in near and far future, because of their high permanence and durability. During the period of last ten years the book and document conversation, especially of those from the 19th and 20th century that show the signs of very quick decay in archives, libraries, museums, galleries all over the world, represents very important activities that demand quick and effective steps. We have studied coated and uncoated boards before and after accelerated ageing to determine the quality and durability of investigated boards. The durability of basic, surface and chemical properties, mechanical endurance, optical stability, as well as printability of boards were investigated. It can be concluded that retention of chemical, mechanical and optical properties depend mainly upon the board composition and type of coating. The low chemical and mechanical stability are proportional to the content of CTMP and recycled fibres.
