Allows you to check if the OPI version of your document complies with the OPI standard used in your workflow.
Open Prepress Interface (OPI) allows you to use only low-resolution images in your documents during the design process. Using OPI, these low-resolution images are automatically replaced with high-resolution images when the separations are printed for the documents. If you use OPI to work with files containing only small, low-resolution images in your page lay-out applications (e.g. Adobe InDesign), you can reduce the processing time when you are working with the files.
If the OPI version of your document is incompatible with the chosen OPI version (1.3, 2.0 or both), an error or warning will be given.
