run-up gilt back
The double gold lines produced by a two-line
fillet which runs along sides of the spine of a
book, and which are intersected at intervals by
double gold lines on either side of each raised
band. The horizontal lines are not mitered, and
they cross the vertical lines, extending to the
edges of the spine. The run-up gilt back
represents one of the few cases where the fillet
is used on the spine of a book. (339 )
