Laser Gravure with Water Based InkTatsuo SHIGETA2000 Volume 37 Issue 2 Pages 56-60
Published: March 31, 2000
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESS1999 was the year when Flexible Packages, printed with Water Based Ink, were introduced into the market. Clients are requesting printing companies to print everything with Water Based Ink in two years. Water Based Ink is sending an important message about environment and machine operator's health and safety from the new century.View full abstractDownload PDF (4807K) -

JOURNAL FREE ACCESSRecently, it is becoming easier for anyone to counterfeit elaborate security documents using color-copy-machines, because of the development, the popularization and the decreasing prices of the high performance machines. Therefore, the security documents with holograms, optically changing inks, etc. have been popular. These optically changing devices have the features of changing image, color and luminosity depending on view-angles. However, the materials used for these devices have some problems, by way of example, the materials are very expensive, and the ways to transfer the materials on the substrate such as paper are restricted. To solve such problems, we have developed a new optically changing device with colored metallic off-set ink consisting of the metallic powder such as aluminum or brass. In this paper, we are going to present the image processing the details and the samples of the new device.View full abstractDownload PDF (5939K) -
6. Compression Methods and Formats for Raster Image DataMakoto MATSUKI2000 Volume 37 Issue 2 Pages 69-77
Published: March 31, 2000
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSPrinting process is becoming an electronic based system very rapidly, especially in the prepress process. It is common to create graphic art data using DTP (Disk Top publishing) system, and output them by image setter or CTP system and print the results by printing press. In order to interchange these data between input and output system, common data format becomes important. Moreover, according to wide spread of internet, it becomes practical to transfer these data and display or print the results at the remote site using printer or on-demand printing system. Under these situations, standardization of data compression method and data format becomes very important. Some of the work for graphic arts is done in ISO TC130. This paper mainly introduces the present state of compression methods and formats for raster image data, such as photograph and line-work data.View full abstractDownload PDF (3434K)
