Abstract

Human endeavor has involved making choices about color and looking for ways to color objects since the dawn of civilization. While it has been the exclusive domain of artists and craftspeople for millennia, the last century has seen the introduction of a scientific basis to color communication. The ultimate goal of this development is for color communication to happen seamlessly and in a transparent way. There are however two categories of challenges here: first, understanding and quantifying color needs and expectation and second, developing control mechanisms that deliver the desired color. In this paper a review will be presented of the color needs in end-to-end color journeys, from initial concept to final colored object and an overview of recent developments in color printing will follow. Topics like imaging pipelines (including the recently-introduced HP Pixel Control), the ease of use of color workflows (including HP Smart Color Tools), the handling of brand or corporate identity colors (via HP Professional PANTONE Emulation) and the measurement of color difference under specific viewing arrangements (i.e., the dENS metric for viewing samples without separation) will be addressed. Finally, a series of challenges for the future will be set out, so that their solution can be approached by both academic and industrial communities.
