Liquid drop discharging device and liquid drop discharging method

A liquid drop discharging device comprising:

• a liquid drop discharging head that discharges liquid drops onto a recording sheet;
• an discharged region computing section which, on the basis of inputted image data, computes a size of a region where liquid drops are to be discharged on the recording sheet by the liquid drop discharging head;
• a discharged region proportion computing section which, on the basis of the computed size of the discharged region and a size of the recording sheet, computes a proportion of the discharged region of the recording sheet;
• and
• a determination section which, when the computed proportion of the discharged region is greater than a predetermined discharged region proportion, determines that sheet curling will occur at the recording sheet on which an image is recorded by liquid drop discharging of the liquid drop discharging head.

A liquid drop discharging method in a liquid drop discharging device that includes a liquid drop discharging head discharging liquid drops onto a recording sheet, the method comprising:

• on the basis of inputted image data, computing a size of a region where liquid drops are to be discharged on the recording sheet by the liquid drop discharging head;
• on the basis of the computed size of the discharged region and a size of the recording sheet, computing a proportion of a margin of the recording sheet;
• and
• when the computed proportion of the margin is less than a predetermined margin proportion, determining that sheet curling will occur at the recording sheet on which an image is recorded by liquid drop discharging of the liquid drop discharging head.
