|+||====== Double ======|
|+||A sheet that is twice pulled and [[l:lift|lifted]] never so little off the [[f:form|form]] after it was [[f:first-pull|first pulled]], does most commonly (through the play of the [[t:tympan-joints|joints]] of the tympan) take a double impression: this sheet is said to double. Or if the pressman run in so, as the foreside of the [[p:platen|platen]] print with the [[f:first-pull|first pull]] into part of the second pull, or the hind edge of the platen print with his second pull into part of his first pull; either of these twice printing is called //Doubling//.|
|+||Doubling also happens through the loose hanging of the platen, and through too much play the tenons of the [[h:head|head]] may have in the mortises of the [[c:cheeks|cheeks]]; and indeed through many wearings and crazinesses that often happen in several parts of the press. —// M//.|
|+||Moxon's account of doubling and its causes refer to the two pull wooden presses, but some of them apply equally to iron presses. In [[c:composing|composing]], the term is applied when a word, a line, a sentence, or any part of the [[c:copy|copy]] is composed twice; that is, if the compositor's eye catch a part that he has already composed, and he repeats it.|
