What is reflow?
Reflow affects character spacing within the fonts to add more space than intended. When it happens it usually changes the layout and spacing throughout the book. This is the main reason we require a hard copy of your inside text pages. Text can reflow for many reasons, the largest being that an element from the original file is missing from the one we are trying to open on our computer — even if there is the slightest variance. Reflow can ruin a project if it is not caught and corrected.
