Abstract
For printing transparencies frames are used which, either by means of their framework or of the borders of transparencies mounted thereon, mask areas which are greater than those of the transparencies. A first frame loaded with a first set of mounted transparencies is placed over a sheet of print material and a first exposure is made. The first frame is removed and a second frame loaded with a second set of mounted transparencies is placed over the same sheet of print material in such a position that the transparencies mounted thereon are in alignement with those areas which were masked previously by the first frame. Then a second exposure is made.
