I'm trying to get some high quality pictures/screen shots of an FEA using the file / save as / JPEG / options / print capture and bumping the quality way up. This worked great on non FEA screen shots before. But in the FEA no matter what quality I use there is no actual change in file size and picture quality. I tried a render, but it just renders the part, not the FEA results. any other way around this? The picture below is the best quality I can get...not very good. 
In the simulation mode, the quality is not great even on the monitor
It gets discussed here occasionally, and the last consensus seen recently is that rendering to the screen is the strongest output feature in Solidworks, better and more consistent than other options. I now take screencaps from a 4k monitor and don't even use the whole screen for report-quality images.
I'd like more for press-quality output, but back in the VGA days I would pan a model and take multiple screen shots at the same zoom level then patch them together in an image editor. It's a pain, and I don't miss it.
I would probably set the background to Plain White.
If you really want to be able to go to town on quality you can vote for SPR 1147124: SOLIDWORKS Visualize: Ability to import Simulation data (Stress plots) and/or SPR 947341: combine display of SOLIDWORKS Simulation results plots for some bodies or components and SOLIDWORKS OpenGL display, RealView display or PhotoView 360 rendered display for the other bodies or components (FEA stress strain displacement temperature finite element analysis structural rendering visualize mesh linear static nonlinear thermal fatigue frequency ) for a chance at seeing it in a future release.
How do I vote on an SPR in the Knowledge Base?
Otherwise I'd echo the sentiments of setting the background to plain white and just taking a screenshot (I use the WinKey+Shift+S tool), that's always been good enough for the reports / presentations I've ever given.
You could also try saving as a PSD file (Adobe photoshop) using the "Print Capture" option with a high dpi setting.
Beyond that, consider voting for the following enhancement:
If the output is tied to your screen resolution, you can always force a higher resolution (super sampling) via your graphics card settings.
If it looks good on your monitor, have you tried CTRL-PrintScrn? This will copy it to the clipboard and then you can paste it into Paint or whatever tool you choose.
