Procedure of printing without relief on diverse flat materials or not guaranteeing in a continuous or discontinuous way an impression without relief with deep penetration of the dyes in one or several colors and that does not need neither a protective layer nor a background layer, this procedure being characterized: a) because at least one printing paste is applied to the surface to be treated, each of these printing pastes having a color or dye, a fatty binder and a vehicle which is also very homogeneous and being finely mixed and blended; b) softens and sensitizes the expressed surface to be treated so that its impregnation by the dye can take place in each printing paste (for example in the heater) c) because the expressed surface treated by washing or rinsing is removed to remove the traces of the vehicle.
