JOURNAL FREE ACCESSThanks to fast algorithms for computing dye set color gamuts and optimal color loci, the color gamut performance of a dye set can easily be quantified as color gamut efficiency. To illustrate this quantification, the area color gamut efficiencies and volume color gamut efficiencies of three hypothetical dye sets and one real dye set were computed.View full abstractDownload PDF (419K) -

JOURNAL FREE ACCESSThe images of color reversal films are often enlarged by high magnification. Therefore, it is very important to improve their granularities.
In the summer of 2000, we released two new color reversal films having ISO speed of 100 and 400 with much finer granularity than those of their predecessors.
In this paper, we will describe the significance to improve granularity of color reversal films and show the new technologies used in the two new films.View full abstractDownload PDF (11543K) -

JOURNAL FREE ACCESSNew color negative films for the advanced photo system (APS) were designed to give more benefit to APS users. The design of the APS films was guided by following important concepts;
(1) better image quality even with under exposure, and higher speed for actual usage, (2) wider latitude for beautiful prints from any scene, and (3) better color reproduction for colors as they are really seen and felt.
For the development, we newly introduced Total Image Quality value (Qt), which is based on factors of sharpness, graininess and color reproduction. And using this parameter, we achieved better image quality.
In this report, these design concepts and technologies are described.View full abstractDownload PDF (4883K) -

JOURNAL FREE ACCESSIn order to ask for the requirement (needs) of the color negative film in domestic prophotographic field, the market trend was investigated. To respond for the market needs, the professional color negative film which uses the fourth layer technology (CL layer) in order to obtain better true/vivid color reproduction (especially skin color reproduction) under various light condition was developed.View full abstractDownload PDF (1965K) -

JOURNAL FREE ACCESS“REXER”, Fuji Film's Dry Imaging System for graphic arts film making, was developed in 1999. This system is composed of a newly developed film “DX” for a laser imagesetter and thermal processor “FDS-6100X”. This film contains the silver halide as a light sensor, the developer, the nucleator and the organic silver salt as the source of image forming silver. The film produces a high image quality by such an infectious development as in “INTEGRA” system. In the present report, the main technology and performance characteristics of the film are described.View full abstractDownload PDF (6208K) -

JOURNAL FREE ACCESSThe research committee for image preservation within the SPSTJ started the image preservation seminar in 1984. Since that year, museums that had photographic collection have been established. The general public has become more conscious of preservation of photographs. Last year, a daguerreotype of the lord of Satsuma (Nariakira Shimazu) was registered as national important cultural property, the first case of photograph. The second was registered this year. Now it is of urgent necessity for our country to educate photographic conservators, as in the United States and European countries.View full abstractDownload PDF (842K) -

JOURNAL FREE ACCESSIn the Information Technology society, how to store photographic information will be explained, especially how to store your photographs in the long terms. Firstly, digital media on access tools, secondly analog media on preservation tools, thirdly relation to cultural assetpreservation will be discussed. Lastly concrete policy for long term preservation of photographs will be proposed.View full abstractDownload PDF (669K) -
Analysis of the Photodegradation Mechanism and, the Improvement of Light Fastness of Dyes by Connecting Light Stabilizing Group (LS-Group)Hisashi MIKOSHIBA, Mithugu TANAKA, Seiichi KUBODERA2000 Volume 63 Issue 6 Pages 322-331

JOURNAL FREE ACCESSPyrazolo [1, 5-b][1, 2, 4] triazole azomethine dyes (PT-dyes) are useful for magenta dyes in D2T2 printing system and photography. We studied the light fastness of PT-dyes. We found PT-dyes with high oxidation potential indicate larger light stability than PT-dyes with low oxidation potential, and found the degradation rate of PT-dyes by UV light is faster than by visible light. And we found the light fastness of PT-dyes was improved by connecting light stabilizing group (LS-group) to PT-dye molecule. We found LS-group of hydroquinone dialkyl ether type is effective for inhibiting photo fading of PT-dyes aused by visible light. And LS-group of UV absorber type is effective for suppressing light degradation by UV light. LS-group of UV absorber type is more effective when LS-group is connected to PT-dye molecule than when LS-group is used as a UV-filter.View full abstractDownload PDF (964K) -

JOURNAL FREE ACCESSArrhenius plots of color differences vs. incubation periods with regard to the principal subject colors in photographic color print were employed to predict dark storage life of the print. The plots were obtained by incubation periods and temperature condition based on the color difference (ΔE*ab=5) which subjectively acceptable without unnaturalness. The predicted lives obtained by the color difference method show considerably shorter than those obtained by the current method which based on the cyan, magenta and yellow densities shift. The results coincide with empirical feeling. It is concluded that the color difference of the principal color is a useful index to predict the dark storage life of color photographic print.View full abstractDownload PDF (3011K) -

JOURNAL FREE ACCESSThe new ink jet printing technology has been developedthanks to the development of a new 6-color pigmented water insoluble ink as well as new matte and glossy media. This technology is able to deliver the image quality that arecomparable to those of traditional photographs and thestability against light, water, humidity and heat that areparameters influencing the image stability.
One of the focal points in ink jet printing has been its lightfast capability. However, the simulated display life of over 100 years with a glass mount under fluorescent light has beenobtained by the accelerated test.View full abstractDownload PDF (454K)
