ジャーナル フリーThis paper describes present newspaper products system. Newspaper editing is generally called CTS. The beginning of CTS is in 1970's. Due to particular needs in Newspaperdom, the development of CTS is unique. In layout form, character typeface and font, measuring type, design and so many things are different between newspaper and printed matters such as book and magazine. There are some essential factors that newspaper editing system disagree with present Desk-Top-Publishing system for book and magazine. By making comparison between CTS and DTP, I am going to prove the point at issue, and consider future directions of newspaper editing system.抄録全体を表示PDF形式でダウンロード (1314K) -

ジャーナル フリーDTP (Desk-Top Publishing) is increasingly popular in Japan, and the demand for fonts of high quality is increasing as a consequence. While dot fonts have been dominant in the past, outline fonts are being used more and more these days. Many of these outline fonts use arcs, Bezier curves, spline curves, etc. to construct curved parts of fonts. The number of Kanji characters standardized in JIS is 6, 355 in JIS X0208 and 5, 801 in JIS X0212. Because of this large number of characters, developing Kanji fonts costs a great deal for a company. For this reason, over sixty companies who share the needs of font development have established the Font Development and Promotion Center. This center is now developing such fonts as Heisei-Mincho, Heisei-Kaku-Gothic, and Heisei-Maru-Gothic. These fonts will be available in the market by 1992.抄録全体を表示PDF形式でダウンロード (1096K) -

ジャーナル フリーThe JBIG coding standard defines a method for the lossless compression of bi-level images. One advantage of the JBIG standard is that it can be parameterized for progressive coding, which has application in image databases that must serve displays of differing resolution and for image browsing. A second advantage it has over G3/G4 Facsimile is superior compression, especially on bi-level images rendered by halftoning. The summary of each technique adopted in JBIG Standard and total compression efficiency is introduced in this paper.抄録全体を表示PDF形式でダウンロード (1253K) -

ジャーナル フリーIn oder to satisfy the user requirements for device-independent printer interfacing, ISO/IEC JTC1/SC18/WG8 has been developed Standard Page Description Language (SPDL). The SPDL is a language for the specification of formatted documents, comprised of black and white, gray scale, or full colour glyph-texts, raster graphics and geometric graphics, in a form suitable for presentation. An SPDL document represents an ideal image specified by composition and layout processes. When given a SPDL document, the SPDL processor with in a presentation device renders the document to the constraints of the actual device so as to provide the best possible approximation to the ideal image. An SPDL document has a layered structure and contents. The structure can be processed independently of the contents. The imaging is performed being based on a two dimensional graphics model appropriate for device-independent usage and for high quality printing. By using font resources defined in ISO/IEC 9541. SPDL can describe complicated glyph-texts containing a number of fonts in any writing modes. The interchange format of SPDL documents has two representations, clear text and binary.抄録全体を表示PDF形式でダウンロード (1209K) -
文書スタイル意味指定言語 (DSSSL) の国際標準化安達 淳, 小町 祐史1992 年 29 巻 1 号 p. 29-37

ジャーナル フリーDocument production is a complex process of multi stages. For efficient document production in distributed electronic publising environment, interchangeability is strongly required in each stage. ISO/IEC JTC1/SC18/WG8 has been developing standards focused on the interchange of the documents produced or being produced. Document Style Semantices and Specification Language (DSSSL) is a standard for associating informations about layout with the documents described by Standard Generalized Mark-up Language, and for interchanging such informations. DSSSL includes a) transformations independent of a semantic processor; b) provisions for specifying the relationship between SGML logical elements and the semantic specific result document; c) formatting and style semantics to describe the style and layout of a document; d) a specification language that describes how DSSSL semantics apply to SGML document instance; e) definitions of machine-processable syntax; f) provisions for creating new DSSSL attributes. These faculities are abstracted enough and needs no localization for Japanese typesetting environment.抄録全体を表示PDF形式でダウンロード (1559K) -

ジャーナル フリーNow we are using efficiently many database systems of technical papers, geographical maps, software and so on. As databases especially concerned with publishing and printing field, book database systems of companies, universities or individuals are used. Tedious and laborious jobs, however, are required to make such database systems. In order to assist in making them automatically, we are developing a pattern recognition method to extract and recognize characters on the shelfback of a book, i.e., title, author's name and publishing company, from a bookshelf image. As the first step of this research, the present paper describes an image processing method to divide a bookshelf image into several books, and extract character regions on the shelfback of each book. This method is also applied to other application, such as automatic checking of book position in a library.抄録全体を表示PDF形式でダウンロード (2565K) -

ジャーナル フリーIn this report, using Fuji Color Art System which is one of surprint off-press color proofing system, fundamental aspects of optical dot gain and answer to reduce optical dot gain quantity in the system are discribed. Using line spread function, we studied optical dot gain in terms of the internal light scattering effect in paper and the light guide effect in the receiving layer. And we found that scattered light intensity at the distance larger than 0.01mm from the center of irradiation was a main factor of optical dot gain. We found two guidances to reduce dot gain quantity. (1) Reduce light guide effect in the layer, using thinner receiving layer. (2) Reduce internal light scattering in paper, using the special paper. Using these two guidance, the new receiver sheet with the thin layer transfer technology utilized cushion effect was developed. And we have succeeded in reducing dot gain quantity without changing the system.抄録全体を表示PDF形式でダウンロード (1434K) -

ジャーナル フリーA method to analyze three dimensional structure of a face using a pair of stereoscopic images of a face is proposed. Inputted stereoscopic images are compared each other to get corresponding point pairs by a kind of relaxation matching method. Obtained three dimensional data of the face are represented by patches defined by B-Spline function, and curvatures of these patches are used to get the top point of a nose. Three dimensional data are also used to decide potential positions of eyes, eyebrows and a mouth, and their exact positions are obtained from pixel values of the inputted stereoscopic images.抄録全体を表示PDF形式でダウンロード (3182K) -

ジャーナル フリーIn lithographic printing, ink and water (fountain solution) are brought on the press and are subjected to shear mixing at the plate cylinder nip. Therefore, the litho ink is to be more viscous and have higher yield value than that of the other divisions of printing such as typographic and gravure printing. Also emulsification characteristics in a litho ink is important for a good press performance. Many attempts have been made to explain the role played by emulsions in achieving a good ink/water ballance during printing. A minimal ink water pickup was sujested as a requirement for optimal ink peformance and for excellent print quality.抄録全体を表示PDF形式でダウンロード (1137K) -
