Factors Influencing the Sharpness of Digital Prints
Abstract:The pixel structure associated with digital printing systems imposes image quality limitations on the print, and these may be a serious impediment to achieving the highest quality levels associated with analog prints. Print resolution or sharpness is a leading component of image overall quality, and will clearly be directly influenced by the pixel dimensions. A metric for image sharpness is proposed which combines the pixel dimensions and the perceptual response of the visual system in an appropriate Fourier-based manner. The resulting digital sharpness scale (DSS) is thus similar in approach to the digital noise scale (DNS) previously described by the author. The digital sharpness scale enables print requirements to be established for digital photography in terms of format, total number of pixels and degree of enlargement, in order to achieve the comparative sharpness levels established for conventional analog photographic processes.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
