In children's book publishing, "bleed" is a crucial term that describes any artwork, images, or colors that extend beyond the actual size of a page, ensuring that when the book is trimmed after printing, there are no unprinted edges showing. This technique is essential for creating a polished and professional look. Typically, the bleed area extends about 1/8 inch beyond the trim line. Properly using bleed helps to account for minor shifts during the cutting process, ensuring that the final product appears seamless and visually appealing.
