The printing process of original graphic prints is an old printing technique dated back to 1796 and invented by Aloys Senefelder.
The process is based on the principle of moisture and colour repelling each other. The image is drawn with a lithographic crayon directly on the printing material. Then the printing material undergoes chemical treatment. During the process, the printing material, which can be stone or plate, is kept wet, so that the colour, which is greasy, is rejected by the wet areas and adheres to the image areas.

In the process where a single colour at a time is applied, the work progresses throughout 2 to 3 weeks in an atmosphere of intense concentration, as the spirit of the moment is captured and preserved on paper.

The definition of an original print is therefore an image conceived by the artist and realized solely in one or more of the printmaking media, where the development and production are strictly controlled by the artist, after which the prints are signed and numbered.
