Paper Abstract

Recently, digital hard copy machines have drawn a great attention because they have good performance of signal processing. Hard copies are directly obtained from video signal by connecting CRT monitor and digital hard copy machine. At that time, many signal processing are considered to produce the desired images. In the color reproduction process, the processing technique that can reproduce saturated and luminous color of CRT monitor by using color ink must be considered, because the color gamut of CRT color monitor is wider than the one that uses in ink for printing purpose. This paper proposes a method of color rearrangment along the constant hue locus to produce correctly the hue of the colors that exist between the ink gamut and CRT gamut. And then, it is shown that the effect is observed clearly in red comparing to the usual color rearrangment.
