DOT RECORDING USING A PLURALITY OF SUBSCANNING FEED VALUES

摘要

Integers that are no less than 2 and relatively prime are selected for the nozzle pitch k and the number of effective nozzles Neff which represents the net number of raster lines in a main scanning direction recorded by one main scan. A plurality of different values are used in combination for the sub-scan feed amount L. It is preferable to select the plurality of different values for the sub-scan feed amount L in such a manner that the offset G, which is a remainder obtained by dividing each value by the nozzle pitch k, is fixed to a constant value. The offset G preferably takes a value in the range of 2 to (k-2). <IMAGE>
