A shallow pan, known as a moulding pan, is then filled with melted
yellow wax, making a smooth, even surface, which is blackleaded. The
pan is then secured to the head of the press, and the form placed on
the bed, which is then raised, delivering an impression of the type
upon the wax.
The pan is removed from the head of the press, placed on a table, and
then built up, as it is termed. This consists in running wax upon
the portions where large spaces occur between type, in order that
corresponding portions in the electrotype may not be touched by
the inking roller, or touched by the sagging down of the paper in
printing.
