>A scanner with a 12" wide and 12" high plate is rare and expensive, true.
And why is that? Why can't someone make a consumer scanner with a
12" x 12" plate? I've never figured that one out.
For that matter, why can't someone make a piece of optical glass that
is about 8" square on one end and 12" square on the other end which
keeps the 12" LP cover in focus optically on the 8" end so that a
scanner can scan it?
