| description | An ink separation device for a printing press ink feed control having a device for printing a color chart having randomly distributed color patches, and recording the cyan, magenta, yellow and black ink dot sizes (CMYK) for each color patch, a device for measuring the red, green, blue and infrared reflection value (RGBI) from each color patch, and recording the RGBI value for each of the color patches, a device for defining a transfer function which maps a four-dimensional RGBI vector into a four-dimensional CMYK vector, a device for forming RGBI measurements over a reference copy, and transferring each of the RGBI measurements into the corresponding CMYK ink dot size value, a device for forming RGBI measurements over a production copy, and transferring each of the RGBI measurements into the corresponding CMYK ink dot Size value, a device for forming the dot size ratio between the production copy and the reference copy to form the ink volume ratio between the reference and production copies and a device for adjusting and ink feed rate of the press. |
