are recessed and engraved in design. Under pressurethe paper is forced into the recesses and against theengraved design so that the uninked portions of thedesign are raised above the surface of the paper. Forinstance, let us imagine that the letter "O" which youare now reading on this page had been printed againsta resilent surface so that the center of the "O" wouldnow be raised as you read it. If the pressman handlingthis particular page has placed a small piece of paperon the cylinder of the press just where this letter appearsyou will see a suggestion of embossing. Embossed envelope stamps are, unlike the adhesivestamps we have described at such length, printed one ata time. Each envelope-making machine is equipped witha single printing die. The blanks from which the enve-lopes are made are cut to shape by means of cutting diesjust as your mother or wife cuts out cookies from therolled dough. These blanks are automatically fed into theenvelope-making machine which embosses a stamp atthe proper place, gums the flaps, folds and seals theenvelope, dries the gum and counts the finished envelopesinto any desired number. An ordinary box of five hun-dred United States envelopes is usually divided intogroups of one hundred. This division is done automati-cally by the machine making them. |
