Batch overlay

Overlay Pages allows you to merge PDF content from two or more files into one PDF that highlights the differences between the files in different colors. This feature is useful when you want to compare original and revised drawings, or when you want to view various building plans (e.g. electrical, HVAC, plumbing, etc.) layered in one PDF. 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.
