Why disable interpolation? Does this have a noticable effect on

An additional remark to the addition of "-dNOINTERPOLATE" to Ghostscript

complaint about too large output files by Ghostscript and I have tried
"-dNOINTERPOLATE" on his command line solving the problem. There you
find also a link to a sample PDF and all Ghostscript command lines for
testing.
