Analysis of Area Field Quality Based on ISO 19751 and ISO 13660
Abstract:
ISO 13660(2001) provides definitions and measurement methods for line width, raggedness, large area graininess, darkness, background haze and extraneous marks. The major shortcoming of ISO 13660(2001) is its inability to describe or address the visual significance of most measured values obtained following the proposed procedures. ISO 19751 even though in development will hopefully expand the definition of print attributes which allow for an easier implementation of the measurement. In this paper, Image quality is evaluated on minute details and characteristics that build up a print, using recommended tools and equipment. This case study is an exploratory experiment to evaluate the print quality with changing toner digital printing screen rules and resolutions. This paper compared large area quality attributes of printed images with different screen rulings and resolution and discussed relationship between quantitative values by Noise Power Spectrum (NPS) and perceptive attributes of images portraits in graphic arts applications.
