In order to design robust image-enhancement techniques for digital prints it is important to understand the fundamental image-quality criteria that provide the basis for satisfactory pictorial print reproduction. Properly established, these criteria are applicable independent of the analog or digital nature of the image, and any enhancement technique should at the least be carried out with an understanding of the before-and-after quality implications. Better still, in the ideal situation the criteria themselves can be used as an integral part of the original design tools during the construction of a systematic rather than an ad hoc set of image-processing techniques.

The present study illustrates the use of basic image quality metrics to construct systematic procedures for the enhancement of digital-print sharpness, and for the satisfactory rendering of images covering a wide range of brightness levels. In both cases this offers the possibility of adaptive and continuously-variable enhancement techniques which are both simple in operation and undemanding of computational resources, and some progress in these directions is reported here.

More about this publication?
  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
