Allright, I have another comparison.
My simple hello.ps file produced by the svn MPL vs test_idl.ps (which has a lot plots --only for test purposes.) file produced by IDL. When I converted the ps file to pdf (using ps2pdf tool) it gets shinier.
Some technical details regarding to the files:
Creator: GPL Ghostscript 870 (pswrite)
Creator: IDL Version 7.1 (linux x86 m32)
See the formats are same. IDL's ps creator does a much better job than the Ghostscript. (Both in terms of fonts and lines, actual frame looks nice in both ps and pdf files.) I use Evince Document Viewer v2.28.2 to view these files.
What could be causing this discrepancy? Is there any way to use an alternative PS creator with MPL? or an option to increase e.g. bits per pixel option somewhere in the configuration?

And I think your ps file itself is okay, but the rendering application
you use is doing a poor job. For example, convert the ps file to pdf
and open in the acroread (or whatever you use).
Yes, it did the job. Thanks for the tip. The fonts look also nicer in PDF. The last interesting thing in the files, the line is rendered as blue on PNG, however in the PS it is red.
