A multichannel printhead is proposed having an array of fluid ejectors for applying a liquid coating material to a surface, characterized in, that each fluid ejector includes a fluid valve with a closing element such as an actuated membrane 8 or an actuated valve seal 11, interacting with a valve seat 10 connected to the valve opening 9, the fluid valve controlling the flow of the liquid coating material through the valve opening 9, that the valve opening 9 enters into multiple fluid outlets 6, that the fluid outlets 6 of all of the fluid ejectors are arranged within a regular array of at least one row, that the fluid ejectors are actuated as to discharge discrete amounts of the liquid coating material through the fluid outlets 6 to the surface according to the drop-on-demand principle, whereas the valve seats 10 and valve openings 9 of at least one fluid ejector are part of a first plate and the fluid-outlets 6 of at least one fluid ejector are part of a second plate. |
