• The interests of scientific research are geometric transformation inversion, on the basis of which, using a graphic editor, a useful model of a tampon printing device is created, which belongs to the polygraphic industry, in particular, tampon printing machines, which are used for polygraphic decoration of sheet materials or bulky products. The technical result of the useful model is the simplification of the construction, the improvement of the operational indicators and the increase of the quality of the seal. Based on these issues, I have constructed and created 5 mechanisms on the basis of research and analysis, which are confirmed by the patent of the invention.
