Nowadays, many artists attempt to make art work from famous celebrated picture or old masters. Usually they implement it using paint brush, or photoshop to analysis the old masters and remake them. It is very normal thing in modern art field. We attempt to remake them using new digital intaglio for automatic non-photorealistic rendering (NPR), it is introduced in this paper. We implement digital algorithm etching like original etching using acid. We analysis and implement old masters to two directions etchings by Haar wavelet transform. The resulting recessed lines are filled with black and the video frame is transferred to the monitor by means of an algorithm on real time. Our digital etching (intaglio printing techniques) remakes another suite of styles that can be effectively applied to old masters. New features include preview video window in real time, shorter drawing time, and displayed two types of etchings video art. It will be very technical and epoch-making art work.
