Function:
Color generation function: By cooperating with different color couplers, CD-4 can generate three basic colors: cyan, magenta and yellow, which are then mixed to form a variety of rich colors, and finally form a complete color image on the film.
Application:
Photography: It is an indispensable chemical reagent in color photography and is widely used in the development process of color film and photographic paper. It can convert the exposed silver halide on the film or photographic paper into color images, so that the photographed scenes and characters can be presented in color.
Printing platemaking: In the field of color printing platemaking, it is used to process color films or printing plates to help generate accurate color separation images, provide a high-quality platemaking foundation for subsequent printing processes, and ensure that the printed products can accurately restore the colors of the original images.
