Abstract

본 발명은 더멀 프린트헤드를 이용하여 연속적인 론으로 화상을 재현하는 것에 관한 것으로, TPH를 이용하여 연속적인 론으로 화상을 재현하는 프린터가 로드량에 따라 파워공급기의 공급전압이 변동되어 재형되는 화상에 불량이 발생되는 것을 방지하기 위하여 1라인을 프린트하기 이전에 가중치에 대한 변수를 계산하여 이 변수에 대한 히팅데이타를 이상적인 히팅 데이타와 합산한후, 이를 TPH 제어부(8)에 전송하여 그 합산 데이타로 프린팅이 수행되게 하였다.The present invention relates to reproducing images in a continuous loan using a dermal printhead. An image in which a printer reproducing images in a continuous loan using TPH is remodeled by varying the supply voltage of the power supply according to the load amount. In order to prevent a defect from occurring, the variable for weight is calculated before printing one line, and the heating data for this variable is summed with the ideal heating data, and then it is transmitted to the TPH controller 8 to add the sum data. The printing was allowed to be performed.

Description

Claims (1)

총 히트 엘리먼트에 대한 히팅 엘리먼트의 비율에 따라 가중치를 다르게한 값을 가중치 롬(7)에 저장시키고, 1라인을 프린트하기 이전에 가중치에 대한 변수를 계산하여 이 변수에 대한 히팅데이타를 이상적인 히팅 데이타와 합산한 후, 이를 TPH 제어부(8)에 전송하여 그 합산 데이타로 프린팅이 수행되게 하는 것을 특징으로 하는 프린터의 재현화상 불량 개선방법.The weighting value is stored in the weight ROM (7) according to the ratio of the heating element to the total hit element, and the heating data for this variable is calculated by calculating the variable for the weight before printing one line. And adding them to the TPH control unit (8) so that printing is performed with the sum data. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
