Abstract
A method and apparatus for setting registration in a multicolor printing machine (1), the print results on print substrates (4) being registered and used to control the production of color separations (3, 3′, . . . ) such that in-register prints are achieved. A change L? in the dimensions (7, 8, 7′, 8′) of the printing substrates (4) is determined by the print, in order to take this change into account such that coincidence can be achieved between a recto print and verso print. This is achieved by the changes in the dimensions (7, 8, 7′, 8′) of the recto print (6) being determined and being used to control the digital production of the color separations (3, 3′, . . . ) for the verso print (5) such that after being printed, it coincides with the recto print (6).
