  印刷前期的工作,一般指摄影、设计、制作、排版、出片等; 印刷中期的工作,通过印刷机印刷出成品。胶片(菲林)是不能直接用于印刷的,用于印刷的色版通常称为PS版,是一种铝质的金属版,色版的一面覆有药膜。
The work at the early stage of printing usually refers to photography, design, production, typesetting, film, etc.; in the middle of printing, the finished product is printed by the printing press. The film (Fei Lin) is not directly used for printing, for printing color version is usually referred to as the PS version, is an aluminum metal version, color version of the face is covered with a film.
在设计中,常常要用到金色和银色印刷,由于金色和银色不能由四色印色来实现,故其印刷和技术都有特殊的要求。
In the design, should often use gold and silver printing, because gold and silver cannot be realized by the four-color ink, printing technology and have special requirements.
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, gold and silver is treated as a spot color, with gold ink and silver ink printing, the film is also a separate color film, film, print, print and separate.

胶片的作用是在曝光时对色版上的药膜进行定影。具体操作如下:把胶片覆盖在色版上覆有药膜的一面,在紫光灯下曝光,胶片上完全透明的地方,色版会被紫光灯完全照射,药膜会完全分解,而胶片上有影像或文字的地方由于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,这样胶片上的影像就完全转移到了色版上。
The film is used to fixing on color version of the film in the exposure. The specific operation is as follows: the film covered on the color version is covered on the film side, exposed under ultraviolet light, completely transparent to the local film, color version will be completely UV light irradiation, membrane will complete decomposition, and the image or text on the film places due to the opaque or not completely transparent, color version of the they do not decompose or not completely membrane decomposition, decomposition of the membrane will be washed off, so that the image on the film is completely transferred to the color version.
在电脑设计时,应定义一种颜色来表示金色或银色,并定义其颜色类型为专色就可满足设计的要求。由于金银和银色是不透明的,故设计时可以对金、银色内容设定为压印(Overpint)。
In the design of a computer, a color should be defined to represent gold or silver, and a color type to be defined as a special color can meet the requirements of the design. Because gold, silver and silver are opaque, the design of gold and silver can be set as Overpint.
在印刷时,色版上有药膜的地方会吸附油墨,随药膜密度的不同,吸附油墨量的多少也不一样,这样就有了颜色深浅之分。
In printing, the color version has film place adsorption ink, with membrane density, the number of adsorption amount of ink is not the same, so there is a color difference.
