Expel (typography)

Expelling is a technical term from the document and refers to a process to text lines in the block set to bring to the intended joint width by the spaces between words can be increased. It serves the reading quality and should avoid sentence errors like whore child and cobbler boy. In hand typesetting , the conceptual work of driving out (or bringing in , as the reduction of spaces between words is called) is followed by excluding , i.e. filling the empty spaces with dummy material from the type case .

While this work is now done by word processing programs , the word spacing had to be changed manually according to a set of rules. For example, subsequent or preceding punctuation marks, the shape of the letters or the length of the words were taken into account when selecting the correct exclusion . The terms locking out or spreading were once used.
