Abstract

Predictable color is the simulation of spot color and pictorial color images using a proofer that resembles the color appearance of a printing press. Color predictability begins with device calibration. This includes standardized Raster Image Processor settings for plates and cylinder engraving ; standard colorants, substrate, and press settings. Color predictability also demands color repeatability. Although time-consuming and unglamorous, color repeatability must be ensured. Rochester Institute of Technology developed color measurement procedures and analysis tools to assist converters with verifying printing conformance. By applying color management tools in a repeatable color printing platform, color predictability from design-toprint, as well as in color proofing workflow, becomes easy.
