Abstract
For a selected class of functions, which describe most typical banding variations, the average response can be found by sampling at only 2th locations, where N is the number of different frequencies of significant banding. This approach makes use of the fact that in most applications the banding frequencies of a given printer system, are known in advance, even if the amplitudes of the banding are not known. Each sample point requires a very small test area or pattern, significantly reducing the overall size of the required test areas.
