Paper Abstract

Dainippon Screen's Color Management System (SCMS) is currently under development for use with device-dependent CMYK-based equipment, and RGB- based devices. SCMS will provide color space transformation of linkage to the CIE 1976 L*a*b* color space. The SCMS concept is based on Screen's CMYK image data formats. The SCMS was announced two years ago at IGAS '93 where many attendees viewed this new Screen approach to color management technology. At DRUPA '95, the SCMS concept for handling RGB-based devices and the transformation of color data between CMYK and RGB-based devices, will be revealed and explained, and this disclosure will be in conjunction with the introduction of products using this CMS technology. Before the full introduction of SCMS at DRUPA '95, this paper reveals the technical characteristics of the color management system as follows: (1) As precise as possible color data acquisition and measurement are carried out. (2) As precise as possible and as flexible as possible device modeling is carried out. (3) As precise a transformation as possible, which is as quick to calculate as possible, is carried out. (4) A different algorithm is used in the case of color matching on the colorimetric measurement, especially on display of creative work by designers.
