Patent ID: 8351070

Claim:
A method of processing image data to obtain image data for printing a circular pad having a radius R by forming ink blots having a radius r in an overlapping manner, the method comprising: setting a base pitch P as a base distance between adjacent ink blots; arranging vector data of the pad in an x-y coordinate system; setting a first base point in the coordinate system; selecting a first determination point, the first determination point separated from the first base point by a unit distance along each of the x-axis and y-axis in any one direction of 45 degrees and 135 degrees (hereinafter referred to as a first direction); comparing a distance from the first base point to the first determination point with the base pitch P; and storing coordinates of the first determination point as print data if the distance from the first base point to the first determination point is greater than or equal to the base pitch P.
