一、前言 在洗印加工中,应用“LAD”标准画面密度值作为洗印加工的一种控制方法(以下简称“LAD”法),目前在电影洗印行业的技术管理中已被广泛应用。以标准画面密度值,这一定量的数据概念代替以往传统的视觉法,改善了视觉因人而异所造成的偏差。“LAD”法应用于洗印行业,其方法简便、易于掌握,这无疑对促进洗印技术管理向科学化、规范化跨进了一大步,
I. Introduction In the printing and processing, the application of “LAD” standard picture density value as a control method of printing and processing (hereinafter referred to as “LAD” method) is currently widely used in the technical management of the film and printing industry. With the standard picture density value, this quantitative data concept replaces the traditional visual method in the past, and improves the deviation caused by the difference of vision. The “LAD” method is applied to the printing and printing industry. The method is simple and easy to grasp. This undoubtedly has taken a big step toward promoting scientific and standardized management of the printing technology.
