TAILIEUCHUNG - COLOR MANAGEMENT- P3

COLOR MANAGEMENT- P3: ICC White Papers are one of the formal deliverables of the International Color Consortium, the other being the ICC specification itself – ISO 15076: Image technology color management – Architecture, profile format, and data structure. The White Papers undergo an exhaustive internal development process, followed by a formal technical review by the membership and a ballot for approval by the ICC Steering Committee. | 6 Color Management Implementation Classification Overview Color management is used and implemented in many ways. As different implementations and specific architectures are proposed it is useful to have a common conceptual framework within which these can be compared. This chapter briefly provides a definition of color management that can be used in the analysis of different architectural implementations. It then presents a general high-level architecture for color management and outlines a continuum for comparing different architectural implementations. In conclusion different categories of architectural implementations are identified and compared using the presented continuum. An important point to note is that there is no universal best way to implement color management. Each implementation will have its trade-offs as it achieves its goals related to color management and the choices involved in these trade-offs are often different for different use cases. This chapter is intended to facilitate analysis and comparison of architectural implementations and as such does not focus on specific workflows. Color Management The ICC glossary defines color management as follows. Color Management Digital Imaging communication of the associated data required for unambiguous interpretation of color content data and application of color data conversions as required to produce the intended reproductions . NOTE 1 Color content may consist of text line art graphics and pictorial images in raster or vector form all of which may be color managed. Color Management Understanding and Using ICC Profiles Edited by Phil Green 2010 John Wiley Sons Ltd 46 General NOTE 2 Color management considers the characteristics of input and output devices in determining color data conversions for these devices. Italics added for emphasis Implementations of color management involve how four important parts from this definition are achieved communication data application and intended
