印刷厂印刷时，金色和银色是按专色来处理的，即用金墨和银墨来印刷，故其菲林也应是专色菲林，单独出一张菲林片，并单独晒版印刷。
When printing, the gold and silver colors are treated as spot colors, that is, they are printed with gold ink and silver ink. Therefore, the film should also be spot color film. A separate film sheet should be produced and printed separately.
在电脑规划时，应定义一种色彩来标明金色或银色，并定义其色彩类型为专色就可满足规划的要求。
In computer planning, a color should be defined to indicate gold or silver, and its color type should be defined as spot color to meet the planning requirements.
印刷前期的作业，一般指拍照、规划、制作、排版、出片等;印刷中期的作业，通过印刷机印刷出制品。
Operations in the early stage of printing generally refer to photography, planning, production, typesetting, film production, etc; In the middle of printing, products are printed by the printing machine.
胶片(菲林)是不能直接用于印刷的，用于印刷的色版一般称为PS版，是一种铝质的金属版，色版的一面覆有药膜。
Film (film) cannot be directly used for printing. The color plate used for printing is generally called PS plate, which is an aluminum metal plate. One side of the color plate is covered with a drug film.
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。
The effect of the film is to fix the film on the color plate during exposure. The specific operations are as follows: cover the film on the side of the color plate covered with the drug film, and expose it under the purple light. 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.
在印刷时，色版上有药膜的当地会吸附油墨，随药膜密度的不同，吸附油墨量的多少也不一样，这样就有了色彩深浅之分。纸张在印刷机里通过C、M、Y、K四块色版的上色，林林总总的色彩就出来了。
When printing, the ink will be adsorbed where there is a drug film on the color plate. The amount of adsorbed ink varies with the density of the drug film, so there is a difference in color depth. The paper is colored by the four color plates of C, M, Y and K in the printing machine, and a variety of colors come out.
印刷后期的作业，一般指印刷品的后加工包括裁切、覆膜、模切、装订、装裱等，多用于宣传类和包装类印刷品。
Post printing operations generally refer to post processing of printed materials, including cutting, film covering, die cutting, binding, framing, etc., which are mostly used for publicity and packaging printed materials.
