Abstract

A recording method for performing recording on a medium by forming dots by ejecting a liquid from nozzles during scanning. The recording method includes detecting an abnormal nozzle; disposing a normal nozzle in a row where dot missing occurs due to the abnormal nozzle by moving a medium by a first moving amount; performing first complementary recording in which at least a part of a dot missing region is complemented by a first dot which is recorded by the normal nozzle during the scanning; moving the medium by a second moving amount; and performing second complementary recording in which a second dot of which a size is greater than a size of a dot determined based on printing data is recorded on a row adjacent to a row of the abnormal nozzle by the normal nozzle that is positioned adjacent to the abnormal nozzle during the scanning.

Dependent claims

A recording method for performing recording on a medium by forming dots by ejecting a liquid from nozzles during scanning in which a recording section having a nozzle column formed of a plurality of nozzles is moved in a scanning direction intersecting the nozzle column, the recording method comprising:

detecting an abnormal nozzle by a detection section during scanning by the recording section;
disposing a normal nozzle in a row where dot missing occurs due to an abnormal nozzle by relatively moving a medium and the recording section by a first moving amount that is shorter than a defined normal moving amount used when no abnormal nozzle is detected during scanning;
performing first complementary recording in which at least a part of a dot missing region in which the dot missing occurs in the first scanning is complemented by a first dot which is recorded by the normal nozzle;
relatively moving the medium and the recording section by a second moving amount corresponding to a difference between the defined normal moving amount and the first moving amount;
and
performing second complementary recording in which a second dot of which a size is greater than a size of a dot determined based on printing data is recorded on a row adjacent to a row of the abnormal nozzle by a normal nozzle that is positioned adjacent to the abnormal nozzle in the nozzle column direction;
wherein the second moving amount is larger than the first moving amount.

A recording apparatus configured to perform recording on a medium by forming dots by ejecting a liquid from nozzles during scanning in which a recording section having a nozzle column formed of a plurality of nozzles is moved in a scanning direction intersecting the nozzle column, the recording apparatus comprising:

a recording section configured to form the dots by ejecting the liquid from the nozzles during scanning in which the recording section is moved in the scanning direction;
a detection section that configured to detect an abnormal nozzle at least during scanning by the recording section;
a moving section that configured to move the recording section and the medium relative to each other;
and
a control section configured to control the recording section and the moving section,
wherein the control section is further configured to perform first complementary recording and second complementary recording,
wherein the control section is further configured such that, in the first complementary recording, if the detection section detects the abnormal nozzle, the control section disposes a normal nozzle that is not detected as the abnormal nozzle by the detection section in a row where dot missing occurs due to the abnormal nozzle by relatively moving the medium and the recording section by a first moving amount that is shorter than a defined normal moving amount used when no abnormal nozzle is detected during scanning, and at least a part of a dot missing region in which the dot missing occurs is complemented by a first dot formed by the normal nozzle in the first scanning, and
wherein the control section is further configured such that in the second complementary recording, the control section controls the moving section to move the medium and the recording section relative to each other by a second moving amount corresponding to a difference between the normal moving amount and the first moving amount, and thereby in the second scanning, a second dot having a size greater than a size of a dot that is determined based on printing data is recorded by a normal nozzle positioned adjacent to the abnormal nozzle in a nozzle column direction of the abnormal nozzle;
wherein the second moving amount is larger than the first moving amount.
