Abstract
In the printing industry, digitalization of prepress based on IT technology advances rapidly, and the efficiency improvement lead by them causes intensification of market competition. In cases for the printing machineries, new products are put into the market in order to handle such situation. Various value-added specifications are prepared for the press to satisfy customers' demands such as high print quality, short turn-around, low cost, and differentiation from competitors. Short-run web-fed printing presses are now entering the market of sheet-fed presses. By above reasons, more complicated specifications must be installed to sheet-fed presses.
