颜色物体的光现象一般有透射、反射、选择性吸收。如图3-20(彩),O是颜色物体,当入射光的光能量为Q入时,经物体O的选择性吸收。其透射或反射出的光能量为Q出。

The light phenomenon of color objects is usually transmitted, reflected and selectively absorbed. As shown in Figure 3-20, O is a color object. When the light energy of the incident light is Q, it is selectively absorbed by O. The transmission or reflection of the light energy is Q.

在输出胶片时,是选药膜面朝上还是朝下,要依出片是出正片还是负片而定。当出片时,选择药膜面朝上还是朝下,得反阳片,当出负片时,选择药膜面朝上,得正阴片。

When exporting the film, is the choice of the film facing up or down, depending on whether the film is positive or negative. When the film is out, choose the film face up or down, get the anti Yang film. When negative film is selected, choose the film face up and get the positive negative.

因为对于正片而言,胶片可以直接晒版,药膜面正好与PS版接触,晒版的效果好。对于负片而言,它必须经过拷贝成正片之后才能晒版,在拷贝时,负片是放在拷贝台上,药膜面向上,上面再叠放拷贝片,这样拷贝片也正好与药膜面接触,以保证拷贝质量。在晒版和拷贝的过程中,光源并不直接照射在药膜面上。

Because for the positive film, the film can be directly printed, the film surface is just in touch with the PS version, and the effect of printing is good. For negative film, it must be copied into a positive plate before the plate can be printed. In the copy, the negative film is placed on the copy table, the film is facing up, and the copy is stacked on the top, so that the copy is just in contact with the film surface to ensure the quality of the copy. In the process of printing and copying, the light source is not directly exposed to the film.
