A correction value determining method of the present invention includes: causing a head to record a first pattern for confirming a transport amount of a medium, while transporting the medium in a transport direction relative to the head in accordance with a target transport amount, obtaining a first correction value that is associated with a relative position of the head and the medium based on the first pattern, the first correction value being a correction value for correcting the target transport amount during transport of the medium, causing the head to record a second pattern for confirming the transport amount of the medium, by transporting the medium while correcting the target transport amount using the first correction value associated with the relative position, obtaining a second correction value that is associated with the relative position of the head and the medium based on the second pattern, the second correction value being a correction value for correcting the target transport amount during transport of the medium, and determining a correction value of the target transport amount by making a use of the first correction value and the second correction value associated with the relative position when the medium reaches a roller provided on the downstream side of the head in the transport direction different from a use of the first correction value and the second correction value associated with the relative position at times other than when the medium reaches the roller.

A printing method includes determining a first correction value corresponding to a first print mode, determining a second correction value corresponding to a second print mode, and correcting an ink ejection amount of each row region individually, using a combined correction value obtained by combining the first correction value and the second correction value. The first print mode is a print mode that is applied to a rear end area, with respect to a transport direction, of a medium. Dot rows are formed extending in a nozzle movement direction that is perpendicular to the transport direction, on a plurality of row regions lined up in the transport direction. The dot rows are formed by repeating a movement ejection operation of ejecting ink onto the medium while moving nozzles in the movement direction, and a transport operation of transporting the medium in the transport direction. The first correction value is for correcting an ejection amount of the ink in each row region individually. The second print mode is a print mode that is applied to a middle area, with respect to the transport direction, of the medium. The second correction value is for correcting an ejection amount of the ink in each row region individually. The correction of the ejection amount using the combined correction value is carried out in a coexistent segment in which certain row regions and another row regions are coexistent. The certain row regions are row regions in which the dot rows are formed by the first print mode. The other row regions are row regions in which the dot rows are formed by the second print mode.

A method of judging whether or not darkness of a foreign matter on a test pattern printed on a medium with predetermined darkness has been read at the time of reading the darkness of the test pattern using a reading section, includes: detecting a section in the test pattern for which an amount of deviation, from a predetermined reference value, of a readout value on the darkness of that section exceeds a predetermined darkness-deviation threshold which is a threshold adopted for the deviation in darkness; and judging whether or not the darkness of the foreign matter has been read based on a size of the above-mentioned section that has been detected.

A printing method includes determining a first correction value corresponding to a first print mode, determining a second correction value corresponding to a second print mode, and correcting an ink ejection amount of each row region individually, using a combined correction value obtained by combining the first correction value and the second correction value. The first print mode is a print mode that is applied to a front end area, with respect to a transport direction, of a medium. Dot rows are formed extending in a nozzle movement direction that is perpendicular to the transport direction, on a plurality of row regions lined up in the transport direction. The dot rows are formed by repeating a movement ejection operation of ejecting ink onto the medium while moving nozzles in the movement direction, and a transport operation of transporting the medium in the transport direction. The first correction value is for correcting an ejection amount of the ink in each row region individually. The second print mode is a print mode that is applied to a middle area, with respect to the transport direction, of the medium. The second correction value is for correcting an ejection amount of the ink in each row region individually. The correction of the ejection amount using the combined correction value is carried out in a coexistent segment in which certain row regions and another row regions are coexistent. The certain row regions are row regions in which the dot rows are formed by the first print mode. The other row regions are row regions in which the dot rows are formed by the second print mode.
