Maybe you can use softwareTecplot instead. Commercial CFD results can be imported to this software. Then you can export hign quality image and change the font.
Dear Arjun, usual commercial CFD software have poor or limited capability for exporting high quality images. I suggest you to save computation results in some data file (like .txt, .xls, .dat) and import it in post-processing (usually free) software like Paraview. Gianluca

As answered by Dr./Prof. Gianluca Argentini, Li, et al. The third commercial software should be used to obtain high-quality image, like Tecplot, Paraview.
In the other hand, you can simply give a high solution pixels to obtain what you need in itself post-processing CFD
You can directly use snipping tool to capture screenshot which is inbuilt in windows and save any formats of pictures and also use Tecplot software instead. options having good results for your case.
