The editor-in-chief delivers then the manuscripts to the printing press for typesetting, pasting-up and printing. During the paste-up phase, he would, however, encounter the problem of "jumping articles." At the same instance, some articles are to be deleted, shortened or long write-ups replaced with shorter ones; thereby generating a new layout much to the chagrin of the staff and the contributors.
Proofreading takes time and effort. One must not only search for typographical errors committed by the human typesetter but by the machine as well. The editor has to scrutinize each word, pica by pica, of every line to insure accurateness of word transfer from the manuscripts to the typescripts. He must pay particular attention to the names of persons, etc. He must decipher which of the punctuations have undergone changes--a comma versus a period, a colon against the semicolon, and vice versa.
