Batch Overlay

The overlay process in Revu lets you compare two or more PDFs by converting each document to a different color and stacking them on top of each other as layers in a new PDF. Each layer is transparent and blends with the layers below it. Where the colors are stacked directly over each other, they blend to create a darker color, making it easier to see which elements have changed and which ones have remained the same from revision to revision.

The Batch Overlay lets you create an overlay comparison for multiple files or a multi-page file in one batch process. The Batch Overlay feature is discussed here. There is also a non-batch version of Overlay.
