In order to increase the contrast between the dark and the light parts of the printing, a blanket was inserted below the sheet to be printed and the typographic plate. This method allowed to get much better overall results without however reaching the quality of the first Athens fine printings or obviously, the one of the Paris printings... This method was giving a strong "foulage" to the stamps, in particular at the shadow lines of the neck, with, very often, a relief ("foulage") visible on the back of the stamp.
