Publication number: 20070109606Abstract: In drawing processing, a function liquid droplet ejection head is moved relative to a workpiece to selectively eject function liquid droplets from a plurality of nozzles of the function liquid droplet ejection head according to ejection pattern data. Calculation is made of an amount given to each of a plurality of imaginary divided portions obtained by partitioning in matrix a drawing region on the workpiece. Matrix data representing in multi-valued gradation the amount of function liquid given to the plurality of imaginary divided portions is generated. N-valued matrix data is generated by converting the matrix data into n-valued data (n?2). The ejection pattern data is corrected to decrease and/or increase the amount of function liquid given to the imaginary divided portions.Type: ApplicationFiled: November 1, 2006Publication date: May 17, 2007Inventor: Nobuaki Nagae
