Stabilnost ekološki povoljnijih ofsetnih otisaka

To achieve the goals of sustainable development, it is necessary to accomplish a balance between technical, economic, scientific, and social development. Ecological sustainability is recognized as a management philosophy, with the aim to maximize the production process and create more value with as small as possible impact on the environment. Ecology efficiency can be achieved by using renewable raw materials and innovative technologies, rational consumption of inputs per unit of product (energy and water), reduction of toxic substance emissions and waste, and closure of the circular flow of production. To implement the mentioned into the production and business system, it is necessary to adopt new knowledge and skills. In this research, the offset prints were made from more environmentally friendly materials. The results show the colorimetric stability of offset prints, obtained by combinations of cardboard (recycled, virgin and FSC cellulose fibres and algae from the Adriatic Sea) and yellow inks (different proportions of renewable raw materials) under defined conditions of exposure to solar radiation through window glass. The research results are discussed in relation to exogenous and endogenous factors responsible for changes in the chromatic values of prints. Photochemical reactions are important because the molecular bonds in the inks weaken in contact with photons.
