Imaging Permanence: Professional Photography
Abstract:The advent of digital imaging has fundamentally changed the workflow of the printing industry and the photographic industry. The media used for printing digital images span a wide range of archival and light stability. Photographic laser recorders expose photographic papers of similar stability performance than traditional photo papers, however other hard-copy technologies and especially ink-jet media have fundamentally different characteristics. Electrophotography, dye-sublimation and ink-jet compete in the photolike imaging market and their light fastness, dark stability and mechanical permanence will be compared.
Ink-jet with its versatility is the most successful among the photo or successors. Depending on the layer system used, polymer or porous, and the inks, pigment or dye-based, aqueous or solvent, the permanence can vary over orders of magnitude. Dark and light stability for such systems need to be taken into considerations. Photo permanence can be surpassed, but only with some compromise in photo image quality or gamut.
All components in an ink-jet system, the base, the ink-receiving layer, the colorants and the ink formulation contribute to the overall stability. The environmental factors, light, temperature, humidity, abrasion and air pollution have different effect on the different ink/media combinations. The influence of the various components and their interaction with the environmental factors will be discussed.
The traditional test methods in graphic arts or photography needed to be supplemented by additional test that are still being developed. A short overview about the current state can be given.

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.
