Abstract
In at least one embodiment, a number of nozzle rows in a first area on a side of one end of a first substrate closest to one end of a print head is set to be lower than a number of nozzle rows on a central side of the print head relative to the first area, and energy for driving the element on the first substrate is set to be larger than energy for driving the element on a second substrate on the central side of the print head relative to the first substrate to set a dot to be formed on the recording medium by ink discharged from a nozzle in the first area to be larger than a dot to be formed on the recording medium by ink discharged from a nozzle in the second substrate.
Claims14
A recording apparatus comprising:
- a print head including a plurality of nozzle rows including an array of nozzles each of which is arranged to discharge ink, and a plurality of substrates on which, for each of the nozzles, an element configured to generate energy used for discharging the ink from the nozzle is provided,
- wherein a relative movement between the print head and a recording medium is operated in a predetermined direction to perform recording on the recording medium, and a range exists where the nozzles are provided in an intersecting direction which intersects with the predetermined direction varying between the plurality of nozzle rows arranged in the predetermined direction in each of the plurality of substrates, and
- wherein a number of nozzle rows in a first area on a side of one end of a first substrate closest to one end of the print head in the intersecting direction is set to be lower than a number of nozzle rows on a central side of the print head relative to the first area, and energy for driving the element on the first substrate is set to be larger than energy for driving the element on a second substrate on the central side of the print head relative to the first substrate to set a dot to be formed on the recording medium by the ink discharged from the nozzle in the first area to be larger than a dot to be formed on the recording medium by the ink discharged from the nozzle in the second substrate.
