Patent ID: 8342633

Claim:
A recording medium recording a computer readable computer program thereon, the computer program enabling the computer to generate dot recording data supplied to a dot recording device in order to perform dot recording using the dot recording device which repeats a main scanning pass and a transport based on the dot recording data so that a raster line along a main scanning direction is formed in multiple lines in a sub-scanning direction on a printing medium, where the main scanning pass is for performing the dot recording on the printing medium when an output head having a plurality of nozzles arranged in the sub-scanning direction moves in the main scanning direction, and where the transport is for enabling the printing medium to move in the sub-scanning direction, the computer program enabling the computer to implement the functions of: determining a dot reduction degree for reducing the dot recording; setting a recording position of a changing target dot included in the dot recording data, according to the dot reduction degree, based on an order of performing the dot recording, where the changing target dot undergoes at least one of a thinning-out processing where the dot recording is not performed and a dot diameter shrinkage where dot size is reduced; and generating the dot recording data in which the recording position of the changing target dot is set.
