First generation microfilm of newspapers shall provide a high resolution quality to allow duplication through as many as four generations. In determining the reduction ratio, the quality index (Q.I.) method as described in ANSI/AIIM MS23-1998 shall be used, with the understanding that other factors – most importantly the condition of the newspapers themselves – will directly influence the choice of both image orientation and reduction. For the master negative (first generation) a quality index of 8.0 or above is generally expected.
