BURNISHING

When it is desirable to have a brilliant polish on bronzed subjects of box wrappers, burnishing is done as follows:

After the wrappers have been sized and bronzed, and after the printing is thoroughly dry, the rollers and disc (or cylinder) of the press are washed clean of the size. We refer to the same press which has handled the form for the bronzing in question. The rollers are then removed. About four extra sheets of news or book paper are placed in the tympan, again underneath the fuller board, so as to make a stronger impression. The same plate or form of type which has been used for the size remains on the press. The bronzed sheets are then run through the press for the second time, feeding them to close register. This second “inkless” printing causes the plate or type-form to polish the bronzed subject on the sheets.
