I did some follow up. From iTunes I was able to produce a CD Cover Insert.
It works...okay.
My CD100 is designed to have title cards + the CD coverart. The Title card is about half the width of the CD cover. Unfortunately, iTunes produces the cover insert that is designed to fit inside the jewel case, so it's twice as wide as the CD Cover Art (front and back of the jewel case).
So vertically the size is correct, but horizontally it's too wide. I was able to just cut out the song listings, and that will work for the moment. I can use the cover art too, if I cut that out, and overlap it over half the listing sheet (which will work in most cases as it won't cover anything up).
Ideally it would be nice to be able to make a custom insert, and somehow adjust the dimensions, but I suspect that won't ever happen with iTunes, since they already procude the standard size insert.
I'm looking for a third party program, but the only ones that I can find run on the mac. Still beats typing everything in by hand.
