Saving a high quality image - export_fig not working

I'm trying to save a high quality image which is an imagsc plot with overplotted contours. The problem is that when I save to .png or .eps the lettering is low quality and pixelated. When I save to pdf or use this command:

print -depsc2 -painters filename.eps

I get files with higher quality font but the image itself has white patches and white lines across it. When I use 'export_fig' which was posted as a solution in other questions, I still get the low quality font, although I did notice that matlab displays the graph with low quality font as well, is there a way to make matlab display a really crips image and then perhaps export_fig will work?
