Help Board-author print

[NATA NOVA]

I met this concept only applying to the printed schedule, when the artist with the engraved them (linoleum, zinc, copper, wood) boards, drawing (on lithographic stones) or by using the grid and squeegee) in shklkografii or even just using a wooden spoon (the remarkable engraver A. Kofanov uses metal)
printed graphic sheets.
Perhaps now use the term "author print" and to duplicating paintings, which the author draws on his orders?
Enlighten us, people!
