Reproduction of Depth of Scene in Some Kinds of Printing
Abstract:We are investigating important physical factors in a display of extra high-quality images. To observe images deeply focusing on the quality of the image reproduction, which is represented by “image depth” or other high-order assessment words, is the best way to find unknown or overlooked factors.
This research report was motivated by observing that when a printed photographic transparency film was observed on white photographic paper, the depth of scene reproduced by it looked greater than that reproduced by normal printing or photograph.
One of the reasons why such first impression was obtained would be due to the good reproduction of black, which occurs because illuminating light goes through a transparency film twice before reaching the eye. For investigating other factors related to the perceived image depth, we removed the difference of the tone characteristics by using a look up table.
The result of the assessment test showed that a combination of internal and surficial reflections of light would enlarge the perceived sensation of “image depth”.
We will introduce other methods that would have the good reproduction of “image depth” as in the case of a transparency film on paper.

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.
