Technical Trends of Offset Paper in Recent YearsKunio Suzuki1992 Volume 29 Issue 4 Pages 384-390
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSIn recent years. especially in Japan. the Grading System of Coated Offset Printing Paper has been changed, and “Bitoko-shi” or Slightly Coated Machine Finished Paper (MFC) appeared. In this paper, focused on MFC producing process. Recent Technical Trends in Coater and Calender, especially in On/Machine-Coater and Softcalender are revealed. Recent Studies about the relationship between Mottle and Coated Offset Paper structure and properties. are also reviewed.View full abstractDownload PDF (1353K) -
Development of the Newsprint Paper Manufacturing TechnologyYoshimitsu MIYATA1992 Volume 29 Issue 4 Pages 391-397
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSIn our country, the sales volume of the newsprint paper hasn't risen markedly owing to the domestic downward economy for the last few years. but its volume has increased steadily each year. And now the imported newsprint paper has only about 1 percent of the Japanese market share in spite of the recent effort to penetrate Japanese market. This is because newspaper publishing companies in Japan aren't satisfied with the quality of the imported newsprint paper, as the foreign paper companies fail to meet the severe quality requrements set by the Japanese customers. Conversely Japanese paper manufactures have continuously improved the quality in response to their quality requirements, and now in consequence of it, the domestic newsprint paper is superior to the imported paper in quality. This article describes a summary of the development of the newsprint paper manufacturing technology in the last twenty years in Japan.View full abstractDownload PDF (1063K) -
Issues in Recycled Paper and their Influence on the Printing CapabilityKazuo KAI1992 Volume 29 Issue 4 Pages 398-406
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSThe effective utilization of waste paper has been strongly required in regards to conserving the global environment and the growing solid waste issues. Japan is one of the leading countries in utilizing waste paper in the world. Waste paper has already accounted for more than half of the fibrous raw materials in manufacturing paper and paperboard. We are concerned that the printing capability could deteriorate because of ink specks, sticky material in wastepaper and the decrease in recycling paper strength. However, the progress of waste paper recycling technology will overcome those problems. Also, the trend of recycling technology in recent years is mentioned.View full abstractDownload PDF (1649K) -
Boxwood Punch and Willow Matrix Lead Type-CastingHiroshi MOMOSE, Takashi MURAKAMI, Masakazu KAWAMATA1992 Volume 29 Issue 4 Pages 407-422
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSThere are 389 lead type pieces remaining from the willow matrix typecastings invented by Kakoku SHIMA in 1870. Following Part 1, this paper discusses the appearance and dimensions of SHIMA's type, along with non-destructive elecrtronic microanalyzer test results. To back up our work we conducted reproduction tests on the unique willow matrix, known only in literature; the creation of boxwood punch; the creation of willow matrix through driving; and the casting of model type through pouring alloyed tin and lead and evaluated the technique of SHIMA in the history of Japanese type-casting technology.View full abstractDownload PDF (4043K) -
Takeshi AGUI, Hisashi TABUCHI, Tomoharu NAGAO1992 Volume 29 Issue 4 Pages 423-430
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSA computer animation method of a falling rectangular light object, such as a post card, is proposed. This method uses kinetic laws for the presentation of translation and rotation of a rigid object, reaction, lift, resistance and so on. Firstly, kinetic laws used in the present paper are introduced, and a method to decide several coefficients in those laws is shown. Secondly, the generation algorithm of image sequences is described, and generated images are shown to prove the usefulness of our method. This method is applied to generation of computer animation of falling objects.View full abstractDownload PDF (1090K) -
Pattern Classification and Color TransformationYoichi MIYAKE1992 Volume 29 Issue 4 Pages 431-436
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSIn recent years, many kinds of color imaging systems have been developed and used. Therefore color transformation between different color imaging systems becomes one of the most important problem to get images with good quality. In this paper, first, colorimetric color reproduction is described. in this method. the transformation matrix for color correction is calculated to minimize the color differences of various colors between different imaging systems. Second, local color correction method which is significant in obtaining the preferred color correction is described. Fundamentals of pattern recognition such as facial pattern detection and pattern classification are also described for preferred color reproduction.View full abstractDownload PDF (1245K) -
1. An Overview of CTSTohru SHIMABUKURO1992 Volume 29 Issue 4 Pages 437-444
Published: July 31, 1992
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSAbout 20 years have passed since CTS (Computerized Typesetting System) has been introduced to the printing industry. The recent development of computer technology has completely changed the style of devices and systems compared to the early days of CTS. Composition techniques for the Japanese language have some conspicuous features that originate in the culture of Japan. The Japanese language utilizes both “Kanji” characters, which were imported from China, and “Kana” characters. which were domestically invented. While “Kanji” characters are ideograms, “Kana” characters are phonograms. Because Japanese is written with these two different types of characters mixed in between. Japanese composition has such unique styles called “Furigana” and “Warichu”. Also, composition for text with Japanese and English characters used together is commonplace. Thus. the composition rules used in Japan are a mixture of rules for different languages and have become very complex.View full abstractDownload PDF (1472K) -
