Abstract
In printing, managing color means that how closely its color reproducts and printing supplier meets customers' requirements. When applying device profiles, it depends on properties of the devices. But color management of domestic digital prints is accomplished more scientifically and objectively than any other printing. According to this paper addresses a method of evaluating between proof prints and offset prints which are produced by identical date on the field. We evaluate two cases normal proof prints and domestic offset prints based on standardized color data analysis and subjective data analysis. We gathered objective data by measuring solid density, $CIEL^*a^*b^*$ and ${\Delta}E^{*_}{ab}$. Furthermore, we evaluated the offset prints and proof prints through human eyes to decide the ranking.
