For example, scanners, digital cameras, and monitors, etc., express the blending ratio to which the light of the three 3 colors "red", "blue", and "green" have been added against the black as values over the RGB color space (Additive mixture of colors). Meanwhile, printers express the blending ratio of 4 the four toner colors "Cyan", "Magenta", "Yellow", and "black" over white (white light) with the three reflected colors "red", "blue", and "green" excluded as values over the CMYK color space. (Subtractive mixture of colors.). 5 The RGB color space and CMYK color space are color spaces dependent on the printer used, and so when converting the color spaces, the colors will be different from the reproduced colors unless consideration is given to the individual printer characteristics. Color matching (recommended) Implementing color matching is recommended for general documents. In general, use this setting. „„Using Windows PS printer drivers 1 Open the file to be printed. 2 Select [Print] from the [File] menu. 3 Click [Advanced] (or [Preferences]). 4 Select [Automatic] in [Color Mode] in the [Color] tab, and then click [OK]. To maintain color consistency from data creation to output, it is necessary to consider the color differences by device when converting colors. This process is called "color matching". The program that implements the color matching is called the "color management system" (CMS). The printer can use either printer driver color matching or application color matching. Note zz Even if using color matching, the printed colors may appear dark compared to the colors on the monitor. This is because the range of colors that can be reproduced by the device is narrower than the range of colors that can be reproduced by the monitor, so even if color matching is used, the vivid colors on the monitor cannot be reproduced. 5 Printing will be implemented.
