Abstract$The article is an attempt to answer the question, how do the optical properties of biodegradable, compostable cellulose films change with time. Samples printed by a flexographic technique with using water-based inks and non-printed films were subjected to artificial aging. Two kinds of cellulose film were used in the experiments. Densitometry and spectrophotometric parameters were measured. It has been found that the type of film determined the resistance to ageing, and under the same conditions one sample almost maintained the measured parameters while the other one changed intensely. The period of artificial aging, equivalent to about three months of natural aging, can cause visible changes in the appearance of non-printed films as well in the quality of copies on those printing substrates. Spectrophotometric parameters better described the changes after ageing then those of densitometry. The tests revealed the resistance of printed and non-printed films to solar radiation.
