Apparatus for printing ink indicia on objects such as fruit and the like, which includes a conveyor to successively deliver the objects to a printing station where the indicia are applied to the respective objects by inked printing dies carried by a printing roller, the objects then being preferably discharged by the conveyor onto an appropriate receiver for collection or for moving them to a further processing station. In order to permit a rapid selection and interchange of inks having different characteristics, a plurality of inking rolls respectively charged with the different inks are carried by a turret assembly which is rotatable to engage a selected inking roll with the printing roller. The inking rolls are arranged to be axially reciprocated relative to the die roll, and are also adjustable to vary the engagement pressure between each of the inking rolls and the die roll. |
