清晰度、解象力和颗粒度是衡量彩色影象质量的重要指标。随着小画面影片的迅速发展,彩色影象必须具有良好的清晰度、解象力和颗粒度,才能保证小画面影片的印制和放映质量。近年来,由于采用薄层涂布,倒型结构(彩正),炭黑防光晕层和吸光染料,以及印片、放映技术的提高等,已经获得了清晰度高、颗粒度低 Sharpness, resolution and granularity are important indicators of color image quality. With the rapid development of small-screen video, color video must have good definition, resolution and granularity in order to guarantee the quality of printing and screening of small-screen video. In recent years, due to the use of thin-layer coating, inverted structure (color is), anti-corrosive layer of carbon black and light-absorbing dyes, as well as printing, projection technology, has gained high definition, low particle size
