When exporting from Prism 6 Windows to EPS, black colors sometimes appear gray.

We fixed this problem in Prism Windows 6.05. There problem is only with the pure black color when exporting to eps. The workaround is simple. Make the black color for labels a bit lighter. For this, go to the Color dialog for labels and set for Red, Green, Blue all to 1 (instead of 0 which is pure black). It will still look black, but now the exporting should go smoothly.
