Catalina Coupons are printed on receipt paper at the store when a customer purchases a participating product. There are strict saturation guidelines to save on ink and printing costs so each print must be designed carefully. These coupons are about 6 inches long and 2 inches tall so the main priority is a big product shot and legible print. The images shown are of a coupon for Nature’s Recipe brand dog food and an announcement print for Kroger’s in-store brand of vegetable oil.
