We have a requirement from an end user to be able to export high resolution PNG (or similar style images) from ArcGIS portal. If the user zooms in on a current PNG format file, it gets grainy really quickly. Effectively, the user wants to be able to put together a presentation where they can zoom in some on a PNG image and be able to see greater detail than the 96 DPI that is rendered by default.
Is there anyway to do this from the Portal/ArcGISOnline environment?
Thank you in advance for your assistance.

You can look into using your own printing utility service within Portal, also described here. You can follow this doc for more advanced ways to print maps.
