胶片的效果是在曝光时对色版上的药膜进行定影。具体操作如下：把胶片掩盖在色版上覆有药膜的一面，在紫光灯下曝光，胶片上完全透明的当地，色版会被紫光灯完全照射，药膜会完全分解，而胶片上有形象或文字的当地因为不透明或不完全透明，色版上的药膜也不会分解或不会完全分解，分解的药膜会被清洗掉，这样胶片上的形象就完全转移到了色版上。

If the film is completely transparent, the color plate will be completely illuminated by the purple light, and the drug film will be completely decomposed. If there are images or characters on the film, the drug film on the color plate will not be decomposed or completely decomposed, and the decomposed drug film will be cleaned, In this way, the image on the film is completely transferred to the color plate.
