Patent ID: 7266802

Claim:
A drawing apparatus for forming a desired drawing pattern by drawing said pattern directly on a drawing target surface of a drawing target substrate using a drawing engine equipped with a plurality of drawing devices arranged along a direction of relative movement of said drawing target surface, said drawing engine being designed so that design spacing of said arranged drawing devices is equal to a product of a unit pixel spacing in drawing data and an integer, said drawing apparatus comprising: correcting means for generating corrected drawing data by correcting said drawing data based on a difference between said design spacing and an actual spacing at which said plurality of drawing devices are arranged; and supplying means for supplying said drawing engine with just said corrected drawing data necessary for direct drawing to a drawing block that said drawing engine can draw at a time on said drawing target surface, each time said drawing target substrate moves in relative fashion by a distance corresponding to an actual pixel spacing that is obtained by dividing said actual spacing of said drawing devices by said integer, and wherein said drawing pattern is formed based on said corrected drawing data.
