What kind of paper is suitable for endsheet stock?
Endsheets help attach the text to the case or cover of a hard cover book. Since one side of each endsheet will be covered with a water-based glue, the paper needs to withstand the swelling and wrinkling this tends to cause. Endsheet stock should be 70 lb. or heavier, uncoated, with the grain running parallel to the fold; 80 lb. is ideal. Grain direction is critical. We have used stocks outside this range before, for example an 80 lb. Karma seems to be fine, but please check with your binding. Endsheets may be colored stock or printed, but do not forget which sides will glue to the cover boards and therefore disappear from view.
