Abstract
Because of high demand of color quality of the prints, proof prints are more important for end-user to predict and correct the final prints directly as an intermediate. Thus, proof prints can be used as a reference to take minimum ${\Delta}E^*ab$between the originals and finals in the field. The advantage of proof prints is to predict and correct color easily through the RIP(Raster Image Processor) without printing plates and plate making steps. While, it is thought that the proof systems are almost equivalent to the press in the past, present proof systems are more simple to take proof prints more easily due to the automation and digitalization. This paper addresses a method to perform an accurate profiling according to proof paper types and find optimal proof papers which meet proofing requirement. Although proof papers are matched with ISO 12647-7, we were trying to reduce ${\Delta}E^*ab$, In addition to the above, through the Gamut Mapping and Iteration, We were trying to find optimal proofing conditions.
