Profiling and Gamut Range
This section is concerned with evaluating the deviation in the scanners’ interpretation of the colors of the original IT8.7/2 target with the help of a color management system. In other words, we will learn the coefficient of the color distortion introduced by the scanner into the image, comparing the measured values on each section of the target to the data from the manufacturer of this target.
The gamut range of the scanner in the visible spectrum is identified with a triangle in the diagram. Knowing the coordinates of the vertices of the triangle we can calculate the total area of this triangle. Then we can compare the Scanjet 8200 to earlier-tested scanners.
Judging by the result, the gamut range of the Scanjet 8200 is almost identical to the standard profile sRGB IEC61966-2.1. By the way, the scanner is an input device, so it must have a wider gamut range than a monitor or a printer.
You can assess the quality of the scans by yourself. Below are images digitized with the HP Scanjet 8200:
