Spectral color control method |
摘要 |
A method for controlling color on press during printing utilizing spectral measurements is disclosed. When a color-difference is exceeded the measured spectral reflectance values of a test area are compared with the corresponding target reflectance values from which a spectral reflectance difference is established. A linear equation is used to relate the spectral reflectance difference to solid ink density or ink layer thickness differences for ink regulation utilizing an on-line empirically established correction matrix such that the spectral reflectance difference is minimized. The control method is applicable to both process and non-process colors.
