IT8 calibration target
Mass production of IT8 Calibration sheets results in slight differences between
production batches. This means that the Colour Patch Reference values in one
batch of IT8 Calibration sheets do not necessarily match those in another
production batch.
Colour matching and calibration are optimal when using your IT8 Calibration
sheet with an IT8 calibration sheet reference data file corresponding to the
sheet's production batch. The Scanner Maintenance CD comes with a number
of these files that are installed with the maintenance program.
The IT8 sheet batch ID is contained in the bar-code on your maintenance sheet.
Your Scanner Maintenance program detects the batch ID so that it selects
automatically the right IT8 calibration sheet reference data file among the list
of files installed on your system.
Normally, this process is automatic. But in some cases, the Scanner
Maintenance program cannot find the matching IT8 calibration sheet reference
file. For example, you may have obtained a calibration sheet to replace your
original one that is newer than your Scanner Maintenance software version. In
such cases, the matching reference file will not have been delivered and
installed on your system.
The following dialog appears when the Scanner Maintenance program cannot
find the IT8 calibration sheet reference file that corresponds to the
maintenance sheet being used:
