The printing technique is a special offset-lithography with a high density of dots. Many of these images are printed on a special paper called hammered cardboard with an ivory surface. It is similar to the paper used by artists for drawing. The paper is very thick, a little rough and therefore very resistant to any damage.

The master printer needs between three and ten times the ink in relation to a normal art print because the surface is not closed and the ink goes deep inside the paper. This makes the image much more brilliant. 

Other images are printed on standard art print paper with a closed surface. The ink sits on the surface of the paper. Again, the printing technique is a special offset-lithography with a high density.

Christo has signed all his prints of preparatory works: his drawings, collages, and paintings. Both Christo and Jeanne-Claude have signed those prints of completed projects.
