ジャーナル フリーThough the digitization of pre-press process was popularized and it did and long, as a matter of fact, many of DTP and CEPS process were only the processes to make data on single page as for being digitizing it. Various CTP workflow systems are provided from pre-press vendors, as well. But, there are many subjects because an analog process must be digitized newly by the printing company, too. Imposition process, proofreading process, last minutes change correction process, plate making process are still full-analog processes themselves. The CTP workflow is to digitize these traditional processes. CTP workflow begins in the place to receive the page data completed with DTP and so on. It is important that the prediction of the output result can be done securely, and it is necessary that therefore each page is the data that it was independent. Using a predictable data format solves some problems. PostScript data received from the DTP process is translated predictable data format. But, there is a problem in being the standard, which several predictable data formats, are characteristic of. It is hoping that CTP manufacturers standardize each of their predictable data formats.抄録全体を表示PDF形式でダウンロード (1816K) -

ジャーナル フリーThe platesetter has a long history. Its development started in 1970, but it has just recently seen mass installation worldwide. The demands of low cost production and fast turnaround have become critical issues for the printing business. These demands, and the progress of digital workflow, have now made the platesetter widely accepted by the market. This paper provides a technology update on platessetters able to output aluminum-based plates. It covers the optical systems and plate material combinations; the three plate exposing technologies, flat-bed, internal drum, and external drum; and mechanisms of plate handling, such as punching and automatic loading. Also presented are an explanation of the platesetter as a component of a workflow system, and an overview of the CIP 3 print production format.抄録全体を表示PDF形式でダウンロード (2973K) -

ジャーナル フリーSince Computer-To-Plate (CTP) systems have been presented as practical technology at DRUPA 1995, its market has grown remarkably. This expansion of the market was produced by customer oriented CTP system development. A lots of photon-mode or thermal-mode CTP plates and suitable platesetters have been launched in the meanwhile. Features and recent progresses of laser sensitive plate technologies are reviewed below.抄録全体を表示PDF形式でダウンロード (2405K) -
DDCPの技術動向 -CTP時代のDDCP-竹田 克之1999 年 36 巻 2 号 p. 105-110

ジャーナル フリーAccording to the recent spread of CTP (Computer-to-Plate), the importance of DDCP (Direct Digital Color Proof) becomes greater and greater, because the DDCP system is a key element of a CTP workflow. In this paper, comparing the feature of some DDCP products, the technical trend and the current status of DDCP is surveyed.抄録全体を表示PDF形式でダウンロード (1948K) -

ジャーナル フリーOne of the main causes of the difference between color photography and printing based on color image reproduction by superimposing C, M, Y and BK halftone dots on paper is the optical dot gain arising from light diffusion through paper substrate. Neugebauer's equation is famous for describing the color print based on halftone dots, but it is very complicated. By assuming additivity of solid optical densities Neugebauer's equation can be resolved into factors and can be transformed into Pollak's equation. By introducing our correction terms for optical dot gain into Pollak's equation through our own method, color reproduction superimposing four color halftone dots is described satisfactorily in the form of spectral reflectance. Our correction terms are quadratic equations of dot area and they have coefficient kλ's.抄録全体を表示PDF形式でダウンロード (1760K) -

ジャーナル フリーIn order to solve the static charge problem, many counter measures have been proposed. To cite some examples, a humidifier, a static charge eliminator and modification of material itself are included and their effectiveness has been proved. In this paper, anti-static technologies by means of surface treatment of plastic materials have been discussed.抄録全体を表示PDF形式でダウンロード (1259K) -

ジャーナル フリーIn the stream of computerization of printing process, only the image input devices have been left behind, and most image data are still made by conventional silver-halide cameras. However, recent development in digital camera technology indicates the posibility of full digital system, where whole printing process is accomplished without making silver-halide negs, prints or reversals. Here, the author compares the digital camera with the conventional camera, describes advantages and disadvantages of each system and also describes present situation of digital cameras.抄録全体を表示PDF形式でダウンロード (2538K)
