화상데이타에 따라 변조한 광비임을 회전경으로 주주사하면서 기록부재상에 결상시키는 레이저 플로터 장치의 망점 데이타 작성 방법에 있어서, 기록부재상에 출력되는 망점의 부주사 방향에 관한 망점농도를 주사계의 오차주기에 가까운 망점주기의 주파수 성분이 최소가 되도록 설정하고, 기록부재상에 출력되는 망점 전체의 농도는 주주사방향의 망정농도로 설정하도록 망점데이타를 작성함으로써, 망점주기의 주파수 성분과 주사계의 오차주기와의 간섭에서의 맥놀이에 의하여 기록 부재상에 출력된 망점에 불균일 농도가 발생치 않도록한 것을 특징으로 하는 레이저 플로터 장치의 망점데이타 작성 방법A method of creating a half-dot data of a laser plotter device in which an optical beam modulated according to image data is imaged on a recording member while main scanning is performed with a rotating mirror, wherein the half-dot concentration in the sub-scanning direction of the half-point output on the recording member is converted into an error period of a scanning system. By setting the frequency component of the near halftone cycle to the minimum and the concentration of the entire halftone output on the recording member as the netting concentration in the main scanning direction, the halftone data is prepared so as to compare the frequency component of the halftone cycle with the error period of the scanning system. Method for creating half-dot data in a laser plotter device, characterized in that the non-uniform concentration is not generated in the half-dots output on the recording member due to the beat in the interference ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
