A method for processing the image to prevent the spread phenomenon in a facsimile comprises the following steps of storing the level a(t) of a back reference surface in a memory, storing the level b(t) of a transript in the memory, comparing a(t) with b(t), calculating the difference (t) in case of b(t)>a(t), subtracting (t) from b(t), storing the level b'(t) of a compensated transmitting manuscript in the memory, compressing, modulating and transmitting the data.
