Printing machine control panel, includes switch to allow buttons to alter status of ink zone without altering its zonal colouration

摘要

A switch (19) can be actuated in order to alter an ink mode for the buttons (13, 14) associated with an ink zone so that at least one button can be used to alter the status of this zone without altering its zonal colouration. The panel has at least two buttons for each ink zone, comprising a first button for increasing a zonal colouration in the ink zone and a second button for reducing a zonal colouration in this ink zone.
