Those patterns were written (back about 1993) to use particular 
PostScript coding that was subsequently deprecated by Adobe with 
later revisions (Levels) of PostScript. 
They do not work at all in PDF, except perhaps if you use Acrobat 
Distiller to do the conversion PS --> PDF. 

Right from the start they only worked properly when the document 
was printed at a decent resolution.
