Paper Abstract

We investigate the factors that determine the consistency of color output on digital proofing systems based on inkjet technology. Because of the multitude of factors involved, only a global solution can prove effective. We develop a complete solution consisting of two main modules. The calibration module contains the tools needed to bring a proofer into a standard condition, for which a predefined tonal response can be guaranteed. The calibration encompasses ink limitation and linearisation. It uses visual quantities, which is most sensible for proofing applications. In the case of multi density inks, the ink mixing is also calibrated in order to remain visually optimal. A convenient procedure is proposed for defining tonal responses, taking into account gamut and bleeding information. The verification module enables the user to monitor the behaviour of the proofer output. It points out problems and also prompts the user to perform suitable actions in order to restore the quality. The intelligence of the module lies in its ability to decide when and how to intervene. This gives the user a practical system that allows to ensure consistency with minimal effort.
