ABSTRACT:
The exposure in color printers has heretofore been determined generally by LATD, but the quality of resulting prints is not always satisfactory. There have been proposed various improvements by making an operator visually inspect a negative film at a former stage of LATD measurement so as to correct the data from LATD or by scanning a frame of film for automatic judgement. They, however, are not quite satisfactory in quality, either. This invention printer allows unskilled operators to attain a high acceptance rate in printing due to the effect by an automatic judgement section as well as enables skilled operators to achieve printing at higher quality and higher acceptance rate.
