1, color restoration processing caused by color distortion

 

Printers usually use C, M, Y, K four color ink to reproduce the color, because of the purity of the ink itself, so printing overprint will also cause color distortion.

 

2, color separation processing caused by color distortion

 

Before printing plate, the image information needs to be converted into C, M, Y, K mode, that is, color separation.

 

The "color separation" is to convert the color information of each pixel of the image into color information suitable for printing mode C, M, Y and K. Color information of catalog printing will be lost in the process of color separation.

 

In color separation, only according to the printing ink, paper and other printing suitability, the correct setting of color parameters can output high-quality color separation, as far as possible to reduce the loss of color information.

 

3. Color distortion exists in the original manuscript

 

Printed image manuscripts are mostly obtained through photography. For the original photo, in addition to the improper operation caused by color distortion in the process of shooting, because the color is through the color material reproduction, and color material is easy to occur color attenuation, so it may also cause the color distortion of the photo.

 

 

4. Color distortion caused by scanning processing

 

The image density of the photo manuscript is continuous, so the catalog printing image information needs to be collected into the computer.

 

For the photo manuscript, scanning is a very key link in image processing, improper operation will cause image color distortion.
