Information Capacity Revisited - Reflections on Print Quality

• The advent of digital printing stresses the importance of quality measurement. Print quality measures that give an objective value have long been sought. The aim is 10 be able to dcscrihe objectively the properties of print on paper so that conclusions regarding the apparent quality can be drawn. In this paper, we discuss the measures proposed in the literature and relate them to the subjective quality. Several years ago, the concept of ‘information capacity’ was proposed as such a measure. Some reflections are made in the light of coding. and telecommunication theory. areas in which in information capacity is a vital tool. On the other hand. for the print quality applications. the interest in in formation capacity has in fact been decreasing. An obvious question therefore arises and is treated in this work: Why have we seen so few applications of this theory for practical applications in the area of print? Is the area of print quality so very different from the areas or image compression and telecommunication?
