Abstract

칼라비디오 프린터의 고속 프린팅 회로가 기술되는바, 이는 원하는 영상을 표현함에 있어서 열프린트 헤드의 각부분의 발열로 인한 온도의 상승을 체크하여 마이컵의 제어에 따라 프린트 헤드의 콘트롤러가 각계조 발열하는 시간을 가변(다운)함으로써 실제 프린팅에 있어 많은 시간을 단축할 수 있도록 구성된다.The high speed printing circuit of a color video printer is described, which checks the temperature rise due to the heat generation of each part of the thermal print head in expressing a desired image, and the controller of the print head generates each gradation heat according to the control of the cup. By varying the time (down), it is configured to save a lot of time in actual printing.
