    PLASTIC MATERIAL
As we know, plastic has the same drawbacks as glass when it comes to inscribing characters, especially because of its polished and non-porous surface, the present invention aims to remedy these drawbacks. .



   The process consists in roughening the face or faces of the mold used for the production of objects intended to receive inscriptions such as labels for displays, school slates etc @
This roughening is very easily obtained by sandblasting the metal of the mold at the desired location 1

The parts produced in such a mold have a.

   slightly rough surface for easy registration
 EMI2.1
 k chalk or with the touch of decoliertees-inscriptions can be erased as easily as on the materials previously used for this kind of writing
The plastic material intended for this use will naturally be dark in color.
The accompanying drawing shows a label with a rough surface, 11 should be understood that the invention is by no means limited to this kind of object 1
