We examine various digital halftoning technique and their application to printings. Three such technique are the error diffusion, cluster dither and disperse dither method. This paper describes a new tone correction halftone method to compensate dot gain. Input digital level are transformed by tone correction characteristics. The function of tone correction are solved from the printer response characteristic. The experimental results show that the proposed method is useful and valid.

In this paper we present work done by Kodak Graphic-Communications-Group and our partners demonstrating applications where laser direct imaging could replace photolithography in display manufacturing. Such applications range from direct manufacturing (e.g. LCD color-filters) to producing “masters” where manufacturing is done by traditional printing methods (e.g. flexography, Gravure-printing).

본 연구는, 기존의 전통적인 패션쇼를 근간으로 빠르게 발전하는 컴퓨터 그래픽 기술을 접목, 새로운 형식의 패션쇼로 최근 연구되는 디지털 패션쇼를 위한 가상 한복 제작과 관련된 연구이다. 한국의 대표적인 전통의상을 소재로, 디지털 패션쇼를 진행하기 위한 가상의 한복의 제작을 위하여 필수적으로 적용되어야 하는 재질들을 분석하고, 사실성 검증을 위하여 전문집단 그룹을 통한 사용성 통계를 진행하였다. 이를 위해 선행연구로 가상 한복 제작에 요구되는 세 가지 필수 재질인 두께, 무게 그리고 색상을 정리한 후, 3D 한복의상을 제작하여 실재 복원된 한복 의상들과 비교, 40명의 피실험자들의 평가를 기준으로 만족도를 조사하여 사용성 통계수치를 통한 분석연구를 진행하였다. 최종적으로 사용성 통계의 분석을 통한 매우 긍정적인 만족도 결과는, 향후 디지털 패션쇼 가상의복의 제작에 필요한 구체적인 재질분석 가이드라인을 제시함에 본 연구의 목적과 의의를 두었다.

Recently, as the prepress mainstream is changed to the digital workflow, various digital proofing systems such as high price dye sublimation printers and low price ink jet printers are widely used in printing industry. However, most of the digital proofing devices have lower resolution than analog proofing systems and differ with actual color presses in the color gamuts. Therefore, proper color compensations are needed for digital color proofing in order to match colors between the proofs and the press sheets. This study shows the application method of Look-up Table to the digital color proofer of Rainbow, the analog proofer of Matchprint-II, and an actual offset press is effective on the color compensations.

Digital image capturing technology has been making great progress recently, and we can now simply capture the color image by digital camera, flat-bed scanner of Photo CD system. A lot of professionals are instrested in the capability of Photo CD and other digital images in the printing and publishing industry. But these images were not processed a suitable image processing to use in the hard copy. In this paper we described a method of the digital enhancement processiing to use in the printing and publishing industry. Experimental result show that the described method was useful and valid for the digital image enhancement to use in the hard copy.

Color reproduction is one of the most important expression factors in digital printing. In this paper, an experiment was done where the characteristics of color reproduction in digital printing. The results could summarized as follows. The printing used device profile showed a color difference of less than printing used default value in digital printing. As a result of weighting color difference, a difference between color gamut of digital original and color gamut of printing, when transforming the RGB color space to CMY color space, a exclusion the gray revision. The solution is to optimize the color transformation by gamut mapping and gray revision.

Digital leader caught seat by modern's everyday life tool now by popularization of smart device such as Smart phone and Tablet PC. Therefore, desire of readers about electronic book practical use is increasing based on convenience and economic performance of electronic book. 1971, Michael S. Hart established Project Gutenberg to produced first electronic book because inputs American Independence Declaration Statement by computer and produce more electronic books. After that, an electronic book technology repeats several times development and American electronic book take is increasing rapidly. Sales volume of electronic books is dramatically increasing in Korea since digital device such as Smart phone and Tablet PC became popular. This research attempts to analyze factors influencing on shifting from paper book to electronic book. Results of this research proposed grounds for building business strategy. Finding is the factor of social influence is only significant to acceptability intention. It means user of e-Book enhance their acceptability intention along social phenomena.

In this study, the graphical design system is developed and the digital mock-up is implemented for designing the spent fuel handling and disassembling processes. This system is used throughout the design stages from the conceptual design to the motion analysis. By using this system, all the processes involved in the spent fuel handling and disassembling precesses are analyzed and optimized. Also, this system is used in developing the on-line graphic simulator to enhance the reliability and safety of the spent fuel handling process by providing the remote monitoring function of the process. The graphical design system and the digital mock-up system can be effectively used for designing the process equipment, as well as the optimization of the main processes and maintenance processes of the spent fuel management.

산업 전반에 걸친 활발한 디지털로의 진전은 영상산업의 전통적인 방법을 변화시키며 새로운 형태로 발전하고 있다. 이러한 영상산업의 발전 중에서도 모션그래픽(Motion graphic)의 활용도와 중요성은 비약적으로 발전하고 있다. 컴퓨터 그래픽은 그 짧은 기간의 역사에도 불구하고 다른 예술분야의 특성을 차용하여 예술의 한 장르로 빠르게 진화하고 있다. 특히 빠른 시간 발전하는 국내의 미디어 환경 속에서 모션그래픽은 전통적인 디자인 영역과 새로운 영역의 디자인에서도 모두 관심을 모으는 부분일 것이다. 짧은 시간 동안 모션그래픽은 영화, 광고, 뮤직비디오, TV, web 등의 모든 분야에서 활용되는 매체로 성장하였다. 그러나 이러한 장르로서의 모션그래픽이 등장한 시점은 얼마 되지 않았으며, 디자이너들이 이러한 영상에 자유로운 기법이나 실험성을 가지게 된 것도 극히 최근의 일이다. 이에 본 논문의 목적은 이러한 발전하는 디지털기반의 영상 제작 환경에서 영상의 한 요소로써의 모션 그래픽의 기본적 요소를 고찰함으로, 이 개념을 정립하려고 한다. 그 요소로는 공간, 모션 그래픽의 객체들의 시간개념과 움직임, 색체와 사운드를 규정하고, 이를 여러 디지털적인 환경에서 규정한다.
