Copper or steel engravings are made from designs furnished either by
the engraver or by some other designer. For simple engraved
lettering such as is customarily used on business stationery, the
cost of a copper plate is about ten cents a letter. For elaborate
designs the costs increase proportionately. Steel plates, which are
more durable, cost about sixty per cent more. Printing from such
plates is considerably more expensive than the two processes
previously described. Engraved letterheads cost from six dollars
upward a thousand for the printing, while the envelopes cost
approximately two dollars and fifty cents a thousand. The envelopes
are usually printed from steel dies, which cost about ten cents a
letter.
