There is no reason for white lines in the aips output.

PostScript is a language that can build complicated definitions on to of 
complicated definitions.  And then use them in ways that are very 
efficient but entirely obscure - the files are unreadable.  We have 
chosen to make our files very readable (plot tasks insert comments into 
the plot files and then into the PostScript to tell you what is coming 
next).

I do know that PostScript from difmap is of the unreadable sort - 
perhaps they do grey scales in some other way.
