A method to pattern films into dimensions smaller than the printed pixel mask size. An exposure coefficient for a second wavelength band that is different from the first wavelength band is calculated using the exposure coefficient for the first wavelength band. The latching plate has at least one nub which, after insertion of the star-shaped part into a star-shaped cutout in the suction pipette held in the magazine and after rotation of the star-shaped part and the latching plate into a locking position, engages in a notch, and which, on insertion of a suction pipette held on the star-shaped part into the magazine, can be moved out of the notch. The intermediate device may provide any one or more of the safety measures described above.
