EMI1.1
Their small thickness meant that the plate in the cassette or camera assumed its correct position in the image plane.
The present invention consists in that the layer is provided with incisions at the edge of the plate or the film, so that a non-depositing crack arises, which is a

The incisions can of course be made on each of the four edges of the plate or only on individual ones. Their shape can be any and their production can be effected by suitable cutting tools, moved by hand or mechanically.
In the drawing, a photographic plate provided with such incisions, for example on all four edges, is shown in view.
The incisions on the edge of the layer can, for example, be made obliquely, arcuate and also run parallel to the edge of the plate. In the latter case you can
