Method for operating a printer, the printer being configured to produce a print in a plurality of swaths, the printer comprising a first carriage configured to move in reciprocation in a scanning direction, the first carriage comprises a main carriage and a sub-carriage, wherein the sub-carriage is moveable in at least one of the scanning direction and the sub-scanning direction with respect to the main carriage, the sub-carriage carrying at least one print head and a second carriage configured to move in reciprocation in the scanning direction, wherein the second carriage carries at least one source of radiation for curing an ink, wherein the second carriage is positioned downstream of the first carriage in a sub-scanning direction, the sub-scanning direction being essentially perpendicular to the scanning direction, the method comprising the steps of: a. operating the first carriage to perform a first cycle in a first amount of time, the first cycle comprising: i. moving the first carriage in the scanning direction from a first side to a second side at a first speed, thereby forming part of an image on an area of the recording medium; ii. moving the first carriage and a recording medium relative to one another in the sub scanning direction; iii. adjusting the position of the sub-carriage with regard to the main carriage; b. operating the second carriage to perform a second cycle in a second amount of time, the second cycle comprising: i. moving the second carriage and the recording medium relative to one another in the scanning direction from a first one of the first side and the second side to the other one of the first side and the second side at a second speed, the at least one source of radiation irradiating the ink; ii. moving the second carriage and the recording medium relative to one another in the sub scanning direction, wherein the first speed is higher than the second speed, wherein the first amount of time equals the second amount of time, and wherein step ii of the first cycle and step ii of the second cycle are performed simultaneously. a. operating the first carriage to perform a first cycle in a first amount of time, the first cycle comprising: i. moving the first carriage in the scanning direction from a first side to a second side at a first speed, thereby forming part of an image on an area of the recording medium; ii. moving the first carriage and a recording medium relative to one another in the sub scanning direction; iii. adjusting the position of the sub-carriage with regard to the main carriage; i. moving the first carriage in the scanning direction from a first side to a second side at a first speed, thereby forming part of an image on an area of the recording medium; ii. moving the first carriage and a recording medium relative to one another in the sub scanning direction; iii. adjusting the position of the sub-carriage with regard to the main carriage; b. operating the second carriage to perform a second cycle in a second amount of time, the second cycle comprising: i. moving the second carriage and the recording medium relative to one another in the scanning direction from a first one of the first side and the second side to the other one of the first side and the second side at a second speed, the at least one source of radiation irradiating the ink; ii. moving the second carriage and the recording medium relative to one another in the sub scanning direction, i. moving the second carriage and the recording medium relative to one another in the scanning direction from a first one of the first side and the second side to the other one of the first side and the second side at a second speed, the at least one source of radiation irradiating the ink; ii. moving the second carriage and the recording medium relative to one another in the sub scanning direction,
