The post-printing effect refers to the visual or tactile changes that occur on a printed material after the printing process has been completed. This can include alterations in color, texture, or finish, as well as any additional embellishments or enhancements applied to the printed surface. These effects can be achieved through various techniques such as embossing, foil stamping, or spot varnishing, and are used to add depth, dimension, and visual interest to the final printed product. The post-printing effect is an important aspect of the printing process, as it can greatly impact the overall look and feel of a design, making it stand out and leave a lasting impression on the viewer.
