1. A liquid-droplet ejecting apparatus comprising:
at least one liquid-droplet ejection head configured to eject a plurality of liquid droplets, each being one of a plurality of sizes, onto a recording medium, the plurality of sizes respectively corresponding to a plurality of predetermined amounts of liquid that are different from each other; a liquid-droplet-ejection-data storage section configured to store liquid-droplet ejection data which causes the at least one liquid-droplet ejection head to eject the plurality of liquid droplets each having one size selected from among the plurality of sizes according to an image formed on the recording medium; a liquid-droplet-ejection-head controlling section configured to control the at least one liquid-droplet ejection head on the basis of the liquid-droplet ejection data; a liquid-droplet-count obtaining section configured to obtain the number of liquid droplets to be ejected for each of a plurality of evaluation regions that are defined on the recording medium and locations of which on the recording medium are different from each other, the liquid-droplet-count obtaining section being configured to obtain the number of the liquid droplets on the basis of evaluation ejection data corresponding to the plurality of evaluation regions among the liquid-droplet ejection data; a liquid-amount obtaining section configured to obtain an amount of the liquid to be ejected for each of the plurality of evaluation regions, the liquid-amount obtaining section being configured to obtain the amount of the liquid on the basis of the evaluation ejection data; a curl-amount obtaining section configured to obtain an amount of a curl of the recording medium on the basis of liquid-curl correlation information, the obtained amount of the liquid for each of the plurality of evaluation regions, and the obtained number of the liquid droplets for each of the plurality of evaluation regions, the liquid-curl correlation information representing a plurality of correlations between the amount of curl, the obtained amount of the liquid, and the obtained number of the liquid droplets for the respective plurality of evaluation regions, the plurality of correlations for the respective plurality of evaluation regions being different from each other; a curl suppressing section configured to change the evaluation ejection data on the basis of the amount of the curl of the recording medium obtained by the curl-amount obtaining section when a processing for suppressing the curl of the recording medium is required, the curl suppressing section being configured to change the evaluation ejection data so as to change at least one of the amount of the liquid and the number of the liquid droplets to be ejected onto at least one of the plurality of evaluation regions on the recording medium to suppress the curl of the recording medium; and a correlation-information storage section configured to store the liquid-curl correlation information comprising a first liquid-curl correlation value and a second liquid-curl correlation corresponding to the amount of curl based on a number of liquid droplets to be ejected for a certain evaluation region of the plurality of evaluation regions in a case when the total amount of ejected liquid in the certain evaluation region is equal, wherein the first liquid-curl correlation value corresponds to a first curl amount that occurs when a first number of the liquid droplets is ejected for the certain evaluation region and the second liquid-curl correlation value corresponds to a second curl amount that occurs when a second number of the liquid droplets is ejected for the certain evaluation region, wherein the first number of the liquid droplets is less than the second number of the liquid droplets, and wherein the first curl amount is less than the second curl amount. |
