print quality in batch mode

Hi,

I have a script that creates multiple figures, which I save as png files using

    print(gcf,'figurename.png','-dpng','-r300');

This works fine when I run it interactively. However, if I send the script to batch the images come out in horrible resolution. I tried to increase the size by setting the position to something larger

    set(gcf,'position',[1 1 1600 1200])

but the image remains the same. I also tried changing the renderer, but that made no difference either.

Is there anything I can do to get high resolution images in batch mode?

I am using Matlab 2012a on Windows 7, but had this problem on previous versions, and also when running on a Linux based system.

But what should be the difference between running in "batch" and interactively? Do you have differen PaperPositions, PaperUnits or PaperSizes? This affects -dBMP256, but as far as I remember not -dBMP...
