Patent ID: 8191980

Claim:
A method of processing image data to obtain image data for printing an edge of a circular pad having a radius of R by forming ink blots having a radius of r in an overlapping manner, the method comprising: setting a permissible pitch range for a distance between adjacent ink blots; arranging first image data about the edge of the pad in an x-y coordinate system; generating second image data with a smaller radius than the radius of the first image data, the second image data sharing the center with the first image data; arranging a first base point on the second image data; selecting a first determination point on the second image data, the first determination point separated from the first base point; determining whether a distance between the first base point and the first determination point is within the permissible pitch range; and storing a coordinate as print data if the distance from the first base point to the first determination point is within the permissible pitch range, the coordinate located at a shortest distance from the first determination point.
