Hi all,
I've now checked some WireComb-bound Letter size books I have.
The 0.5 inch spacing pattern was used, but there were only 21 holes
not 22!
Looking at the twentyTwoHoleUS pattern specification in the Finishing MIB,
worst case there is only a 0.09" margin to the edge of the paper
(0.32" diameter holes). This seems awful narrow, so 21 holes
seem to make actually much more sense.
BTW: For A4, 0.5" spacing seems to use 23 holes in the examples
I have seen.
Any comments are very much appreciated.
Best regards
