Claim of US Patent No. 10,434,769

1. A method of depositing printing fluid on a sheet of corrugated media with an array of nozzles, the method comprising:determining a height displacement of the sheet at multiple locations on the sheet with respect to a reference height;
determining a gradient of the height displacements at multiple locations along the sheet:
adjusting control parameters for each of multiple nozzles, including at least one of:
increasing an angle of tilt of the nozzle at a location of a gradient that is more steep than another gradient;
increasing a spray angle of the nozzle at a location of a height displacement that is smaller than another height displacement;
increasing a spray angle of the nozzle at a location of a gradient that is less steep than another gradient;
increasing a spray flow intensity of the nozzle at a location of a height displacement that is smaller than another height displacement; and
increasing a spray flow intensity of the nozzle at a location of a gradient that is less steep than another gradient; and
depositing printing fluid from the plurality of nozzles onto the sheet of corrugated media according to the adjusted control parameters.
