Recording device, image processing device and recording method

An image processing device configured to generate recording data for making a recording device perform recording based on image data, the recording device being configured to record a recording image based on the image data by repeating a pass operation in which a nozzle set discharges a liquid while reciprocating relatively to a recording medium in a main scanning direction to form dots on the recording medium, and a conveying operation of relatively moving the nozzle set and the recording medium in a sub-scanning direction crossing the main scanning direction, the image processing device comprising:

• a halftone processing section configured to generate a plurality of halftone data corresponding to the liquid of a predetermined color with respect to a same area of the image data based on the image data;
• and
• an assigning section configured to assign each of the halftone data to the pass operations in a same direction in reciprocation in the main scanning direction in a predetermined recording area.

A recording method in a recording device configured to record a recording image based on image data by repeating a pass operation in which a nozzle set discharges a liquid while reciprocating relatively to a recording medium in a main scanning direction to form dots on the recording medium, and a conveying operation of relatively moving the nozzle set and the recording medium in a sub-scanning direction crossing the main scanning direction, the method comprising:

• generating a plurality of halftone data corresponding to the liquid of a predetermined color with respect to a same area of the image data based on the image data;
• and
• assigning each of the halftone data to the pass operations in a same direction in reciprocation in the main scanning direction in a predetermined recording area.
