Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1852 edition. Excerpt: ...The plates employed for printing the postage stamps are fine oblong pieces of steel--gleaming like the steel mirrors which the Roman girls used to see themselves in--(mirrors well adapted to such a stern people.) Each plate is large enough to have ranged upon it two hundred and forty penny " Queen's Heads;"--one pound's worth. The effect, therefore, is that of a beautiful mirror, in which you see Her Majesty's countenance repeated two hundred and forty times in close lines. The security against forgery lies in the engine-turning on the "basis" or ground, on which the head is done; in the great excellence of Mr. Charles Heath's design; in the exquisite beauty of its execution, and in the perfect identity--barring, of course, the accidents of printing--of every Queen's Head, one with another. But the chief advantage of the invention is the power it confers of rapid production. The number of postage labels required for the public service is--casting out Sundays--upwards of one million a-day; it was nearly three hundred millions for the three hundred and sixty-five days of 1851; fifty-two of them being Sundays. Let us see, then, what labour would have been required to keep pace with this prodigious demand, had Mr. Perkins's invention not been in existence: --It took Mr. Heath a fortnight's hard work to engrave, on the original steel die, the profile which is the progenitor of all the rest. Had there been no power to transfer that work to other plates for print ing, of course every head must have been separately engraved by hand on the printing plates, each at an equal expenditure of time. What, therefore, occupied originally a couple of weeks, and which now occupies no more than a few minutes to manufacture plates for printing...show more
