The method described below allows the possibility to use extra-fluid Latex printhead trenches uniformity,
keeping stable the firing frequency and optimizing the nozzle usage.
Some pritheads include two trenches firing the same fluid, but each trench is independent. In order to fire
one image using both trenches, the need arises to use a half density mask to eject drops. These masks
must be complementary each other. It is known as pairing.
This solution defines the strategy of pairing to ensure the firing frequency control according to the
