<P>PROBLEM TO BE SOLVED: To provide a method and a device for adjusting a drawing condition to reliably reduce jaggy in an image pattern when the image pattern is drawn on an image recording medium by using a plurality of two-dimensionally arranged drawing elements. <P>SOLUTION: An optical magnification β that can control the displacement LER(β) of a recording position of a drawing point formed by micromirrors 40 with respect to a Y direction into an allowable range is set from the relation among the distance TY0 in the Y direction between mirror images projected onto a substrate F of the micromirrors 40 constituting a DMD 36, an inclination angle θ of the DMD 36, a recording pitch ΔY of the image pattern and the optical magnification. <P>COPYRIGHT: (C)2008,JPO&INPIT |
