This accident frequently occurs: — in the course of working at press a letter or letters will draw out in beating, and occasionally be left on the form without being perceived; this, when the next impression is pulled, injures the page on which it was left; — a pin, needle, or bodkin, used as pickers, will sometimes be laid on a page and forgot — and other small articles, which produce the same injury.
It also happens with forms reared up at the ends of frames, where the faces of the letter in the forms are put to each other, with a quoin, or a piece of furniture, to prevent them touching, which being accidentally displaced, the letter gets injured. The only thing to be done when these accidents occur, is to replace the letters; this however is too frequently done without showing a revise to the Reader or Overseer; and thus errors creep into a work, which no care on the part of a Reader can prevent. To steady careful men these accidents seldom happen; and they ought to be guarded against, in as much as they cause loss of time to the workmen, and expense of materials to the master printer; and when letters or words must be replaced, the work should never be proceeded with at press, previously to its being examined.
When a fine engraving on wood is at press, the workman should be most particularly careful, as an accident might thus spoil an expensive work of art, which it might be impossible to replace.
When a Batter unfortunately happens at press in working stereotype plates, it is too frequently overlooked by the pressmen, and the work proceeds in a deteriorated state; while, generally speaking, if the same accident had happened to a form of moveable types it would have been set right. The reason is, that while in the latter case the accident could be remedied in a few minutes, the stereotype plate on the other hand would have to be taken out of the form and sent to the founders, and would not be repaired in less than five or six hours, during which time the pressmen would be unemployed, to their loss. This is one cause that operates against the more general use of stereotype plates.
