A method and apparatus for setting register on a multicolor printing machine ( ) having color printing units ( ) allocated to various printing inks and having image cylinders ( ), equipment ( ) for producing images, in particular electrostatic latent images, on the image cylinders ( ), a carrier ( ) for printing substrates ( ) and image transfer points ( ) for the transfer of the color separations ( ) from the color printing units ( ) to the printing substrates ( ), an allocation of the image productions ( ) on the image cylinders ( ) to the printing substrates ( ) being carried out in order to achieve coincidence of register of the color separations ( ) in the print. This is achieved by a time-independent allocation of the positions of the image productions ( ) on the image cylinders ( ) to the printing substrates ( ) being carried out for at least one defined area ( ) of all the color separations ( ).
