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.

在電腦規(guī)劃時(shí)，應(yīng)定義一種色彩來(lái)標(biāo)明金色或銀色，并定義其色彩類型為專色就可滿足規(guī)劃的要求。

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.

印刷前期的作業(yè)，一般指拍照、規(guī)劃、制作、排版、出片等;印刷中期的作業(yè)，通過(guò)印刷機(jī)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.

膠片(菲林)是不能直接用于印刷的，用于印刷的色版一般稱為PS版，是一種鋁質(zhì)的金屬版，色版的一面覆有藥膜。

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.

膠片的效果是在曝光時(shí)對(duì)色版上的藥膜進(jìn)行定影。具體操作如下：把膠片掩蓋在色版上覆有藥膜的一面，在紫光燈下曝光，膠片上完全透明的當(dāng)?shù)兀鏁?huì)被紫光燈完全照射，藥膜會(huì)完全分解，而膠片上有形象或文字的當(dāng)?shù)匾驗(yàn)椴煌该骰虿煌耆该?，色版上的藥膜也不?huì)分解或不會(huì)完全分解，分解的藥膜會(huì)被清洗掉，這樣膠片上的形象就完全轉(zhuǎn)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.

在印刷時(shí)，色版上有藥膜的當(dāng)?shù)貢?huì)吸附油墨，隨藥膜密度的不同，吸附油墨量的多少也不一樣，這樣就有了色彩深淺之分。紙張?jiān)谟∷C(jī)里通過(guò)C、M、Y、K四塊色版的上色，林林總總的色彩就出來(lái)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.

印刷后期的作業(yè)，一般指印刷品的后加工包括裁切、覆膜、模切、裝訂、裝裱等，多用于宣傳類和包裝類印刷品。

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.
