[Fundamental study on stability of dry-processing imager system DRYPRO 722/SD-P].

: Dry-processing leaser imager systems have become popular due to the advantages such as the elimination of the cost and labor associated with the wet chemical processing. In this paper, the stability of a dry-processing imager system Drypro 722/SD-P was studied using SMPTE pattern films processed by a dry-processing imager Drypro 722 and a wet-processing imager Li-8/SRX-502 at three different times of the day over a period of five consecutive working days. The dry system is inferior to the wet system on the stability and the spatial uniformity, so that the problems assess the necessity of QC for Drypro 722 Laser Imagers. The instability of the post-processing dry and wet films is also studied. The dry film is very instable compared with the wet film. Accordingly the wet film must be handled with the care.
