Abstract
Dynamic Color Render Dictionaries are provided to automatically switch color rendering behavior between object types. The implementation resides entirely within the Color Render Dictionary (CRD) and require no changes to the state of the Postscript interpreter (There are no required 'C' code changes and Postscript operator redefinitions.) The different color rendering behaviors are accomplished by concatenating multiple color transform tables into a single/RenderTable within the CRD. The different rendering behaviors are accessible to single graphics state by simply accessing different regions of the /RenderTable. By having the color rendering behavior 'switch' without changing the graphic state makes the implementation very fast. Since the entire implementation is limited to the Color Rendering Dictionary, dynamic CRDs may be implemented on any existing Postscript printer. Even on ones that have been in the field for years.
