Paper Abstract

Ink limit is an important parameter for printer color calibration, especially for inkjet printers. A GCR approach is often used to control the total ink amount for CMYK printers. However, a tradition GCR approach has the following limitations: 1) it can not reduce the total ink amount to less than 200 percent for CMYK printers; 2) it can not be applied to reduce ink for CMY printers; 3) to achieve highest image quality, ink amount may be limited to different values in different regions, in which the GCR approach fails. In this paper, a new approach is presented to control ink limit. It controls ink limit globally as well as locally. An algorithm was developed to construct a gamut boundary for gamut mapping that guarantees that the constructed gamut surface covers only colors within the ink limit. If the ink limit needs to be modified, the gamut surface is reconstructed based on the original measured data. Therefore redoing and remeasuring a target is avoided. It greatly simplifies the ink limit control and color calibration.
