Method of dealing with curl, droplet ejecting apparatus, and program for dealing with curl

摘要

A method of dealing with a curl of a recording medium caused by ejection of a liquid by a droplet ejecting apparatus to the medium, including the steps of: calculating (1) an ejected-liquid amount ejected to an evaluation region defined on the medium and (II) an ejected-liquid associated quantity which is one of (a) an ejected-liquid-droplet number ejected to the evaluation region and (b) an ejected-area associated quantity which is one of an area of unit regions in the evaluation region to which the liquid is ejected; and a ratio of the area of the unit regions to an area of the evaluation region, and estimating at least one of a curl degree of the medium caused by ejection of the liquid thereto; and a correction degree necessary for restraining the curl, on the basis of a position of the evaluation region; and the calculated ejected-liquid amount and ejected-liquid associated quantity.
