Abstract
A recording apparatus according to the present invention has a structure such that recording position of each dot is inverted in one pixel area in such a manner that a direction in which dots of lines in the main scanning direction to be formed on a printing sheet is made to be different from the main scanning direction. Even if the printing sheet feeding apparatus encounters displacement and the position of the printing sheet with respect to a thermal head is displaced, the foregoing structure causes dots to be formed in a zigzag configuration for the lines in the main scanning direction of the printing sheet on which a dot pattern has been formed in accordance with image data so that generation of moire fringes in the main scanning direction is prevented. Since the recording apparatus according to the present invention enables a required printing mode to be selected from a plurality of printing modes for the printing processes for printing yellow, magenta and cyan color components, generation of moire fringes in the main scanning direction can be prevented and change in the hue can be restrained without deterioration in the resolution of the recorded dots even if the position of the magenta dot or the cyan dot is displaced with respect to the position of the yellow dot.
