    As recent technical progress in color image coding and input and output systems such as scanner and printer, color images are becoming to be treated as digital data in many case. According this trend, demands for transfer these data to a remote terminal or interchange them between different systems are increasing day by day. As the increase of these demands, several kind of standardization works for the interface of these systems are carrying out. In this paper, some example of such works are introduced, especially for color facsimile, color representation method in the internet, and ICC profile.

  • Direct Thermal Full-Color Recording Paper : Thermo-Autochrome Paper

    A new continuous tone full color direct thermal recording system named"TA"(Thermo-Autochrome) system has been developed. The TA system uses the TA paper which has three recording layers, each corresponding to yellow, magenta and cyan color forming layer wherein a color image is formed in situ. After each color development by thermal head, each layer is fixed by decomposing a diazonium salt compound remaining in each layer by UV light except the cyan layer to be processed finally and located innermost. The TA system does not accompany any waste such as an ink ribbon or an ink cartridge. This is one of the main advantage of TA system over current conventional hardocopy systems.

    We have developed Elgraphy system, which is a new hybrid imaging technology using electrophotography and liquid cryatal technology. Elgraphy has some interesting characteristics such as dry system, high definition and a large number of pixels etc. Elgraphy system is expected an alternative technology of silver halide photography and digital camera system.

  • Transfer Mechanism of Color Dye in Sublimation Transfer Printing by Laser Heating

    In laser thermal transfer printing using dye sublimation type medium, a high definition and continuous tone image can be obtained easily because the laser is focused to small spot and heat energy can be controlled by the pulse width modulation of laser light. In this report, we made the ink sheet that was composed of the laser absorbing layer, yellow and cyan sublimation dye layers in order to investigate the transfer mechanism of color dye. By the measurement of absorption spectrum of transferred dyes, we have confirmed that the dye in the front surface layer and two color dyes are transferred in the range of low and high recording energy, respectively. The expansions of ink sheet and receiving sheet were observed with Atomic Force Microscope. The color dye can be transferred uniformly from the ink sheet to receiving sheet because the ink sheet contacts with the receiving sheet by the thermal expansion of both sheets.

  • Hardcopy among Various Information Media

    With the wide spread of personal computer, more and more visual information is being fully digitized. Under such a trend, the status of hardcopy which has been long recognized as the most human-friendly medium seems, at least partly, ruined. On the other hand, the visual pschology as well as the viewing behaviour of hardcopy observers is being made clearer through the comparison with the behaviour towards other media. The paper deals with specific human behaviour in hardcopy viewing, and then discusses the future of communication media technologies.
