Abstract:
A dot-recording method using a dot-recording device for recording ink dots on a surface of a print medium, the dot-recording device including a dot-recording head having a plurality of dot-forming elements for ejecting ink droplets and a platen configured to extend in the main scanning direction and to be disposed opposite the dot-forming elements at least along part of a main scan path, the platen having a slot configured to extend in the main scanning direction, a width of the slot in the sub-scanning direction corresponding to a specific sub-scanning range on a surface of the dot recording head including at least part of the plurality of dot-forming elements, the dot-recording method comprises the steps of:(A) setting an expanded area in accordance with a type of print medium to be used in the dot recording, the expanded area extending lengthwise beyond at least front and rear edges of the print medium, and representing a recording area in which images are to be recorded on the print medium; (B) preparing print data for recording images in the expanded area; and (C) performing edge printing by ejecting ink droplets from at least some of the dot-forming elements disposed opposite the slot when images are printed at least in front- or rear-edge portions of the print medium on the basis of the print data; wherein a relatively large expanded area in the sub-scanning direction is set to a print medium that is included in relatively more slippery type of print medium with a specific dimension in the sub-scanning direction, and a relatively small expanded area in the sub-scanning direction is set to a print medium that is included in relatively less slippery type of print medium with the specific dimension.
