Hi all,
Long ago I noticed that the text in our PDF manuals is fully black,
which results in rough-looking text when printed:
http://lists.gnu.org/archive/html/lilypond-devel/2008-10/msg00059.html
Attached is a patch which corrects this, and the printed output is
noticeably improved. (The on-screen output is nearly
indistinguishable.)
I'll send this to the TexInfo folks as well.

Subject: [PATCH] Fix TexInfo PDF output text color
Changed CMKY colors to RGB colors, as RGB black prints
better than CMYK black on home printers.
