Abstract
Most of the information collected by MIS consists of information generated during prepress, which is then used as parameter information for press and postpress. Under current conditions, it is most efficient for the operator engaged in prepress processing to input detailed parameters that anticipate every stage of the workflow (except for order receipt), and it is logical to have the role of entering the required JDF information divided. For this reason, even in the JDF workflow, prepress operation plays a critical role in the workflow. Moreover, I think that the JDF workflow should pursue not only the cost reductions that can be achieved through automation and increased efficiency, but also improvements in quality. The typical example of this is the problem with color quality control. It is reasonable to consider it the prepress vendor's mission to create the specifications required to solve the problems related to this important theme.
