Neugebauer Model of a Four-Color Inkjet Printer

A series of research tasks were carried out to build a model of the printers output. First, various correction methods of Neugebauer equation were analyzed, and put forward a new correction method that is using exponential correction method with considering the impact of dot gain, this model was selected as the forward model and its accuracy was tested throughout the colorant space. It was found to be highly accurate. Next, encryption arithmetic was tested when CMYK values were in deferent intervals, and the best model was taken as the four color inverse model. Last, the profile obtained by the up model was contrasted with the profilemaker in accuracy, the result is very ideal.
