Drive out

Matter is driven out when it is purposely set widely, or branched out. Many compositors indulge in a greedy habit of spacing their matter widely near the end of a paragraph, in order to drive it out so as to secure a fat breakline. This system is reprehensible, as it disfigures the page, and should be checked by the reader marking it back again on the proof. When, by reason of insertions in an author’s proof, the sheet is overrun, the surplus lines at the end are termed “driven-out matter.”
