Newspaper publishing houses have been facing growing challenges for some time now. These include falling subscription figures, reduced circulation and market penetration, and the constantly growing demands on the quality of newspaper printing. Further difficulties are posed by the global overcapacity in almost all relevant newspaper markets coupled with rising expectations of newspaper print quality, especially in the advertising business.
