|+||====== Ruck ======|
|+||In printing at machines, the paper, particularly if it be soft and not flat, in travelling round the cylinders frequently wrinkles; this is termed //Rucking//, or the// Paper Rucks//, or the //Paper is Rucked//; when this takes place, the sheets may be looked on as spoiled when it is for [[b:books|book]] work: the best preventative is to press the wet paper well in a powerful press for an hour or two, with small quantities between the boards, just before it goes to the machine. I would not recommend more than five [[q:quire|quires]] in each portion, although I am aware that a [[r:ream|ream]] is generally put in; but the smaller the quantity between each two boards the flatter the paper will be, and less likely to ruck.|
