Came across this forum having just started using Spark yesterday and discovering the resolution problem already. Yes it is embarassing to think that you're exporting a high-res image only to see it on the other side be anything but.
My workaround was to download as PDF, and in Photoshop save as PNG or JPG. I'm sure there are other ways to save a PDF as an image, but I ended up with a high quality JPG.

It is embarassing from Adobe...
Hope this helps
