tipping front and back
The process of placing a narrow line of adhesive
on the sides of a sewn pamphlet near the spine,
for the purpose of securing the cover of the
publication along the sides instead of simply at
the spine, which may have insufficient surface
area to hold the cover securely. However, it is
usually necessary to score the covers at the edge
of the line of adhesive, otherwise there is the
risk that the cover paper will break at the
adhesive line. 2. The process of attaching
endpapers in edition binding. (142 )
