Abstract

본 발명은 감광식 칼라 비데오 프린터에 사용되는 액정 발광소자, 액정 씨알티등의 헤드 성능열화나 특성 변화에 의한 색조변화를 체크하는 것에 관한 것으로, 이러한 장치는 프린트 헤드(1)에 입력신호(iR,iG,iB)를 입력함으로써 프린트를 수행하기 때문에 프린터 헤드(1)에 발생한 특성변화에 대한 동작제어를 수행할 수 없게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to checking change in color tone due to deterioration of performance or characteristic change of characteristics of liquid crystal light emitting devices and liquid crystals used in photosensitive color video printers. Since printing is performed by inputting R , i G , i B ), operation control on the characteristic change occurring in the print head 1 cannot be performed.

즉, 고온의 주변환경이나 장시간의 사용으로 인한 특성 변화로 같은 입력신호(iR,iG,iB)에 대하여 원하는 칼라를 얻을 수 없는 경우가 발생하게 되는 문제점이 있게 된다.That is, there is a problem that a desired color cannot be obtained for the same input signal (i R , i G , i B ) due to a change in characteristics due to a high temperature environment or a long time use.

이에 따라, 본 발명의 목적은 상기와 같은 종래의 감광식 프린터 장치에 따르는 결함을 해결하기 위하여 프린트 헤드의 특성변화에 따른 칼라의 왜곡을 스스로 캘리브레이션(calibration)할 수 있는 기능을 추가함으로써 항상 일정한 색조의 칼라 프린트를 수행할 수 있는 프린트 농도 자동 보정장치를 제공하는데 있다.Accordingly, an object of the present invention is to provide a constant color tone at all times by adding a function capable of self-calibration of color distortion caused by a change in the characteristics of a print head in order to solve the defect caused by the conventional photosensitive printer device as described above. The present invention provides an automatic print density correction device capable of performing color printing.
