Catalogs are multi-paged printed materials that can either be stitched or wire-bound on the sides. They are popularly used as menus, service and product listings and directories. Like magazines, they can often be kept by customers for future reference or left in stores for daily use.
It is only but necessary to design these catalogs well and to only have its color printing done by a proper print shop. A good design and print makes readers want to read the catalog from cover to cover, and perhaps even want to order more stuff than they initially intended.
