By default, the ANSYS Mechanical viewport is pretty crappy for exporting images. If you take a screenshot, the text will be small and pixelated. ANSYS provides the ability to export the viewport as a file, upscaling to some desired target resolution.

Under the "Home" tab, click "Images"
Click "Image to File"
Uncheck "Current Graphics Display" (this is the aforementioned "crappy" viewport)
Set the "Enchanced resolution" and especially "Font Magnification factor" settings (1.5 is the most common, you should play with it and see what looks nicest, then make sure everyone else uses the exact same settings)
Click OK, save the image
