Cowie's Printer's Pocket-Book and Manual/Of Imposing
OF IMPOSING.
Imposing comprehends not only the knowledge of placing the pages that they may, after they are printed off, follow each other regularly, but also the manner of dressing the furniture, and making the proper margin.
Having composed as many pages as make a whole sheet, half sheet, or less part of a sheet, of whatever size, they are taken from under the frame, and carried to the imposing stone; taking care to put the first page in its right position, with the signature to the left hand, facing us, according to the following schemes:—

- ↑ Imposing in quires may be carried to any extent, by observing the following rule:—suppose the work to consist of 32 pages, or 8 sheets, then any two pages whose united numbers make 33. are to be imposed together; as, 1, 32—19, 14—12, 21, &c.
There must be less furniture in the backs or the inner sheet than the outer, to allow for stitching.
- ↑ A sheet in sixteens, with two signatures, is imposed as two sheets of common octavo, putting the first signature for the one half sheet where A stands above, and the first page of the other half sheet in tha place where the fifth page is.
