Waterproof board books are constructed to endure contact with water and are therefore suitable for bath time or outdoor activities. These books utilize materials that are resistant to water like synthetic papers or coated cardboard. The printing process applies water-resistant inks and seals the text and illustrations with coatings to maintain the colors and text integrity when wet. Some waterproof board books have sealed edges or lamination for additional water resistance. Their strong construction lets children freely handle and explore the books without the risk of damage, making for a pleasurable reading experience in wet environments.
