Abstract
A method for copying relatively thin documents of semitransparent or thin stock which permit images on the reverse side to show through to other portions of the copy apparatus. A sensing system is employed to sense the density of the document and otherwise determine that background images may show through. The copier may automatically produce a black sheet for backing on the thin or semitransparent stock and the original copy using the copy lighter feature to eliminate the uniform gray background which would otherwise be produced. This can be done automatically or on command by the operator.
