摘要

In recent years, the resolution in digital printing has been becoming higher, in response to the need for high image quality. However, since there is a cost disadvantage to using a smaller exposing beam, methods like PWM control only used, and real high resolution has not been achieved. For this reason, high-resolution stable single dots and single lines cannot be formed. To improve the sharpness and halftone of images and to achieve a photo-quality image, the high-resolution image forming technology is required. To help allow for the employment of smaller exposing beams, for example using blue lasers, we have conducted the study reported in the present paper in which we have investigated the necessary conditions for the high-resolution latent image forming and development process. In this paper, we first discuss our frequency analysis of the latent electric field, through which we have determined an OPC thickness that can give single and periodic lines simultaneously between 600 and 2400 dpi. Next, we discuss the test-bed we constructed and our experimental examination of the characteristics of single line and periodic line image forming at 1200 dpi. Finally, we consider the effect of several methods on high-resolution image forming.
