   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

 this is indicated in the drawing on the right. The crack created by the incision forms a non-disruptive and at the same time completely safe mark of the sheet layer side that can be felt by hand.
