This standard addresses routine usage of test target elements for quality control testing. It does not address any precise evaluation of specifically defined characteristics (resolution, modulation transfer function, sensitometry, etc.) of an imaging system. The total target area described in this standard is based on the dedicated image area specified in AIIM MS41.
The format of this standard allows the user to prepare a test target for an image area that is determined by the selection of a reduction ratio. This standard requires the notation of the reduction ratio used in creating the subsequent microfilm image of the test target.
