Drop size modulation
The VarioPrint i-series printhead nozzles can produce drops of five different sizes. This
mechanism is called
drop size modulation
. The largest drop size is only used to compensate for a
failure of an adjacent nozzle. (

[12] Five different drop sizes
Media characteristics such as surface roughness and the type of coating determine how a ink
drop behaves when it touches the media. The media definition has parameters that determine
which drop sizes the print engine must apply while printing these media.

[13] Drop size modulation: the printer adjusts the drop size depending on the media characteristics. Media with
coating (top) allow for a larger drop size than media without coating (bottom)
Background spitting
Background spitting is the production of small ink drops during printing. These ink dots on the
media sheets are not a part of the source image but are jetted the background of the image. They
are not visible to the human eye. Background spitting keeps the nozzles open and clean.
