Abstract:
An ink jet recording method which receives a command and data which indicate a drawing of a thick line or a filled-in area, analyzes the command and the data by an interpreter, converts vector data of the thick line or the filled-in area into raster data based on a specified data pattern which contains a predetermined matrix of ON and/or OFF dots, after the analysis, and, based on the raster data, ejects ink droplets while moving a recording head over a recording medium with a plurality of ink ejection nozzles arranged thereon, said method comprising the steps of:before converting to the vector data to the raster data, checking by said interpreter whether the data pattern indicates solid-drawing in the thick line or the filled-in area or which the drawing is indicated; if the data pattern specified to a particular thick line or filled-in-area indicates solid-drawing, changing the data pattern for that particular thick line or filled-in-area to a data pattern of a lower-density for preventing an ink splash during printing; and converting the vector data of the thick line or the filled-in area into raster data based on the vector data and the data pattern when ejecting ink droplets according to the raster data; wherein said recording method is performed while operating said recording head in a single pass recording mode.
