Due to the great demand of the digital process in the printing industry, there is an increasing market of the digital press in Taiwan. Digital printing technology does not only save printers production time and cost, but also provide flexibility on the short-run, on-demand, and variable-data printing. It has become a major technology trend in the printing industry. Print quality is always an important issue associated with the technical development of any printing machine. One of the major quality concerns for most printers is the characteristic of the color reproduction for digital presses. Therefore this study focused on the investigation of color reproduction for the major digital presses in Taiwan. It intended to study the color gamut difference among digital, conventional sheetfed offset, and hybrid presses. The presses used to run the experiments for this study were Agfa Chromapress 50i, Indigo E-Print 1000, Xeikon DCP-50D, MGI Digital Carte Master Color (digital presses), Heidelberg QuickMaster DI 46-4 (hybrid Press), and Heidelberg SpeedMaster 102-5 (conventional offset press). A digital test form was used to run the experiment; the CIELAB readings were obtained by a X-Rite 528 and the data were used to draw the color gamut for each press. One hundred printed sheets were collected for each press after the press was determined to be at equilibrium, and 50 of them were systematically random sampled. The results of the color gamut for all presses are presented in the paper and their comparisons are also reported..
