Auto IT8 Calibration is incredibly easy to use and I noticed an immediate effect when scanning my color transparencies. Having an accurate color profile for your scanner gives you a better start point for your scans and as we all know the better the start point is the better the final result will look.
The IT8 standard has been the color control reference for graphical applications for over 20 years. Industry designers, photographers and even every-day photo enthusiasts rely on the color accuracy made possible by the individual ISO norms of the IT8 Standard.
During scanner calibration, measuring tables help characterize the specific color reading capabilities of a scanner. These measuring tables are built in accordance with the ISO-Norm 12641. The measuring tables recognize the individual characteristics of the particular scanner and generate a color profile for said scanner. It is quite common for scanners to contain singularities that make them unique from one another. These singularities often occur during the production process and tend to continue to change throughout the life of the scanner. More precisely, this process is a profiling of the scanner, however, both terms (calibration/ profiling) are used. It is also common for color differences to occur due to environmental factors such as room temperature, humidity and light exposure. A profile in accordance with the IT8 Standard is thus a useful tool not only for professionals, but for all those interested in scanning.
