OPI Swapper is a plug-in for managing low and high-resolution data in InDesign documents within the scope of an OPI system. It quickly and efficiently swaps OPI layout data for OPI high-resolution data and vice versa, allowing all documents opened to be swapped at once. Low or high-resolution data can be loaded with a single mouse click. Additionally, OPI Swapper can automatically search and replace image paths, and can be adjusted to any OPI system due to its wide range of preference options.
