Image quality attributes are important keys for evaluating quality of printed areas. According to ISO 13660 (2001), the first international standard for digital printing, describes a set of image quality attributes for large area including graininess, mottle, darkness, background haze, and voids. Most research about image quality is focused on graininess and mottle. There were very limited reports about image quality of darkness, background haze, and voids. Image quality evaluation in large area is a multi-parameter process. The parameters include printing processes, inks, substrates, and RIP quality. It is necessary to understand the image quality attributes of all aspects. In this paper, the image quality parameters of large area are analyzed based the prints output by a HP indigo press. Different paper types and halftone screen rulings were considered for evaluating the print quality of large area. The result suggested that the image quality attributions defined in ISO 13660 (2001) could be used for evaluating image quality of solid and halftone areas.
