You should know about the color printing factory

  The color printing process is used for digital scanning of the manuscript, and the manuscript is divided into red, green and blue components. Before the development of digital imaging, the traditional method of color color separation was to take 3 images of the image, and each time a different color filter was used to filter different light. However, after the separation, the result is 3 grey images, representing the red, green and blue components of the manuscript respectively.

  The next step is to convert each color color slice. When generating the red component of the negative image, the generated image represents the green component of the image. In the same way, the green components and blue components of the negative images are also generated, so as to produce the finished red and yellow dichroic films accordingly.

  Cyan, magenta and yellow are subtractive primary colors, because each color represents the two remaining additive primary colors subtracted from the white light. Cyan, magenta and yellow are the three main pigments in color reproduction. These three colors can be combined in printing to make a reasonable copy of the original, but this is not the case in practice. Because of the limitation of ink pigment, the darker colors are dirty and dirty. In order to solve this problem, we need to create a black plate to improve the color of the dark part and enhance the contrast of the image. Various techniques have been developed to produce this black plate from the original image; these include grey component substitution, background color removal, and background color addition.
