To create a PDF variant of the Document select Plug-Ins>GN4>Create PDF. A dialog is shown with a choice of variants (if more than one in the system). The variant name needs to map to the InDesign PDF export styles. The name can have 'PDF_' in front of it as this is removed when looking for the PDF export style.

There is a mapping of the Adobe PDF presets in InDesign to export the document as a PDF variant in GN4. The presets need to be added as Doc variant types in GN4. They can have 'PDF_' put in front of the name as then it will display in the Create PDF dialog.

To load PDF as such and to review it in Adobe Reader (needs to be installed on your workstation), click the link in the Variants section of the preview.
