Scanner profiling is the process of determining the precise color characteristics of a scanner or digital camera. VueScan uses IT8 targets (also called Q60 targets) to do this.
IT8 targets are included with many scanners. You can also obtain IT8 targets from several sources:
Kodak: http://www.scarse.org/docs/kodak/Q60-order.pdf Wolf Faust: http://www.targets.coloraid.de/To profile your scanner or digital camera with an IT8 target:
VueScan normally reads and writes the ICC profile for the scanner using the file scanner.icc. Alternatively, you can type the file name of the ICC profile into Color | Scanner ICC profile.
Every IT8 target has an associated data file that describes the exact color of each square in the target. You should either rename this file "scanner.it8" or type the file name into Color | Scanner IT8 data.
Both the .icc and .it8 files are normally located in the same folder as VueScan.ini.
Note that the settings in the Color tab do not affect the profiling. To see if the profiling works correctly, you should set Color | Color balance to "Neutral".
