Galley glitches are errors that occur in the final stages of the publishing process. TYPOS, a five-letter solution to the crossword, is one type of galley glitch. TYPOS are mistakes in typing or printing, such as spelling errors, incorrect punctuation, and incorrect grammar. Other types of galley glitches include incorrect page numbers, incorrect font sizes, and incorrect margins. All of these errors can lead to costly delays and reprinting costs.
