In Preferences > Impose, Default scale values for imposed jobs sets the default scale factor when Fiery Impose Plus starts. Finish Size is based on the PDF crop box or trim box settings.

1. For Finish Size, click Based on Crop box or User Defined.

   • Based on Crop Box, the default and legacy Fiery Impose Plus workflow, depends on the PDF crop box.

   • User Defined allows Impose to detect the trim box settings, when present within the document, and use these as the default finish size. It does not depend on document size and crop box.

2. For Default scale values for imposed jobs, choose a scale setting as described in Default scale value.
