JOURNAL FREE ACCESSPush-processing of a color reversal film is widely and generally used in saving a mistake due to underexposure, or in case of shooting when a high speed is required such as sports photography. Because of these, there is an extremely high demand from the market for improvement in pushprocessing characteristics of a color reversal film. This paper describes the push-processing mechanism of a color reversal film, and introduces the technology to improve push-processing behavior and its application to.an actual product designing.View full abstractDownload PDF (682K) -

JOURNAL FREE ACCESSIt is often beneficial to incorporate chemical addenda into color photographic elements rather than adding them to processing media. Usually, it is necessary to deactivate these incorporated chemicals so undesirable interactions with other coated components are not caused. During the development of such films the deactivated reagent may be unmasked via reaction with a component of the developer solution; the active addenda can then afford its desired effect, perhaps seen as an alteration in silver development kinetics. Recently, it has been found that nucleophilic aromatic substitution reactions of electron poor aromatic compounds can be employed to allow the incorporation of silver development inhibitors into color reversal films. This inhibition chemistry has been found to be of use in controlling the push processing of color reversal films. Synthetic, mechanistic, and photographic aspects of this technology will be discussed.View full abstractDownload PDF (1211K) -

JOURNAL FREE ACCESSWe have developed an image simulation system with an excellent accuracy in regard to image reproduction and simulation computation. As for the interimage-effect simulation in this system, where 3D-LUT (3 Dimensional Look-Up Table) method is applied, we have achieved a color reproduction accuracy of within as small as 1.0 of the average color difference. The developed image simulation system has been applied to the designing tone and color reproduction of an actual color reversal film.View full abstractDownload PDF (4204K) -

JOURNAL FREE ACCESSColor reversal films incorporate design factors to optimize their performance across all features important to customers who use the film. One important customer featureis film acutance, a measure of the film's ability to clearly record fine detail. This article quantitatively describes the benefits of several essential film architecture tools used to manage exposure and processing effects on film acutance. Among the factors described are light management by absorber dyes, interlayer filter dyes, film thickness, and silver halide content in the yellow color record. Alsodescribed are emulsion bulk iodide influences on chemical acutance effects. Some acutance performance tradeoffs with other film features are described. The quantitative importance of these tools depends strongly on particular emulsion optical and chemical influences in any given film. In general, the cyanrecord shows the strongest acutance dependence on film properties related to light scatter and reflection because of its position near the bottom of the film multilayer stack. Absorber dyes and interlayer filter dyes improve cyan and magenta record acutance at the expense of photographic speed. Emulsion bulk iodide tunes IIE effects and delivers a corresponding influence on the chemical aspects of film acutance under a white light exposure, although many other factors also influence these behaviors.View full abstractDownload PDF (1128K) -

JOURNAL FREE ACCESSThe environmental safety has become one of the most important issues in the photographic industry as well. The latest version of Konica's color paper (Konica Color QA Paper Type A7) was designed to improve the fitness to the global environmental protection as well as photographic performances, such as whiteness of the background, tone and color reproduction, and the stability of printing and processing characteristics. These features were achieved by newly developed EFB technology, Hyper-EXR grains, and P2 & R2 technology. Design concept and new technologies of the color paper are reported in detail.View full abstractDownload PDF (631K) -

JOURNAL FREE ACCESS‘Standard Object Colour Spectra Database for Colour Reproduction Evaluation (SOCS)’ was developed. The database was designed so that object color spectra are systematically divided by category, according to the purpose to which they are to be applied, and every category has a sufficient variety of samples. The categories are as follows: photographic materials, graphic arts printing, computer colorprinters output, paints, flowers, leaves, human skin colors and historical Krinov data. The first three categories are important for color scanners and the last four categories are important for digital cameras. Paints data will be essential for digital archive applications. The total number of colors is 49, 672. The database is being published as, a Japanese standard technical report and being proposed to be an ISO technical report for use in establishing new color reproduction evaluation method.View full abstractDownload PDF (13530K) -

JOURNAL FREE ACCESSA quick-drying, high-water-resistant glossy ink jet paper is developed that offers superior ink absorbability and exceptional drying speed without sacrificing fine high gloss and hardy waterfastness. Three new technologies make this possible: micropore forming with fine-grained silica, dye fixing by organic-inorganic complexed particles with a new cationic polymer and silica, and a water-resistantink-absorbing layer with polyvinylalcohol and boric acid.View full abstractDownload PDF (4256K) -
