I will try the printer soon. But indeed, gv indeed failed to render the 
pattern in antialiasing mode. I remember that the error appeared 
earlier, but than it appeared just as a solid block instead of a pattern 
fill, or a solid fill didn't appear at all.

I will look whether this might have caused the color fill issue; sorry 
again for the confusion I caused when mistakenly announcing a similar 
error with png or even standard terminal; it may definitely have been 
the postscript error. However, I could not reproduce this after some 
sort of panic (I have to submit a plot with such filled curves for a 
publication to the corresponding author of the paper as soon as 
possible). Please see my e-mail, too.

Best wishes,

Ingo
