[0031] Taking a CMYK (cyan, magenta, yellow, black) four-ink printer as an example, the specific implementation method of the above characterization model correction method is described. It should be noted that the present invention is not limited to four-ink printers, and is applicable to correction of spectrum-based characterization models of various multi-ink printers.
[0032] The establishment of a printer spectral characterization model based on a certain printing environment is a prerequisite for model correction. There are two types of forward spectral characterization models for printers: model method and empirical method. The model method is to simulate the coloring mechanism of the equipment through a physical model, and establish the corresponding relationship between the ink formula and the spectral reflectance, such as the Kubelka-Munk model, the Clapper-Yule model, the Neugebauer model, and the Cellular Yule-Nielsen Neugebauer model. Orientation models are ofte...
