High-Resolution is a term used to describe images that contain a high level of detail and clarity, making them ideal for print publications such as children's books. In the world of printing, high-resolution images typically have a minimum of 300 DPI (dots per inch), which ensures that when printed, the colors are vibrant and the images are sharp. This level of quality is crucial for capturing the attention of young readers and effectively conveying the story through rich illustrations. Authors and illustrators often work closely to ensure that the artwork meets high-resolution standards for publication.
