Quality control checks




Overall looking for accuracy (adherence to technical specs), completeness and consistency.  A general practice is for the person conducting the quality review not to be the same person who performed the actual scanning as this helps to have a fresh set of eyes when reviewing details. Another approach is to wait a reasonable period between scanning work and QC review.


Check list




(1) Note on color management - use AdobeRGB1998 color profile ( since using flat bed scanner and monitor calibration may not be feasible. Recommend using a standard ICC to maintain consistent color throughout images )
