Utilizing the Wide Colour Reproduction Area of Adobe RGB
Adobe RGB is a practical RGB color space that was introduced in 1998 by Adobe Systems Inc. As you can see from the color reproduction area comparison graph of Figure 1, compared with sRGB, Adobe RGB has a greater range in some parts of the color reproduction area, such as from blue to green.
Adobe Photoshop can now handle image data that has been stored according to the Adobe RGB color space. Furthermore, there are now high performance scanners and digital cameras for professional use that use the Adobe RGB color space. When Adobe RGB is used for the image data, the monitors used to display these images also need to support the wide color reproduction area of Adobe RGB.
If the monitor is able to reproduce colors according to the Adobe RGB color space, it will be possible, for example, to display on the monitor the correct color reproduction area of the data of an image taken by a photographer using a digital camera in Adobe RGB mode. Another merit is greater precision when editing the image.
In the field of prepress, as you can see in Figure 1, Adobe RGB covers the color reproduction area of the ISO-Coated color space, which is one of the standard color sets of the printing industry. Therefore, if the monitor can reproduce the Adobe RGB color space, color corrections to the soft proof can be done with greater accuracy.
Moreover, printing processes with a broader color reproduction area than sRGB are now available to us such as Hexachrome®, which includes orange and green in addition to the four colors of cyan, magenta, yellow, and black. When this kind of process is used, better image quality is expected and this creates demand for monitors with a wider color gamut.
