Spot Color refers to a printing technique where a specific ink color is used as opposed to blending colors from a four-color process (CMYK). In children's books, this method is often used to achieve vibrant hues or unique colors that cannot be easily replicated through standard mixing. Spot Colors can enhance visual storytelling and emphasize specific elements, allowing for greater artistic expression. This technique is particularly popular for illustrations, covers, and special features that require precise color accuracy.
