Digital printing is the process of printing digital-based images directly onto a variety of media substrates. There is no need for a printing plate, unlike with offset printing. Digital files such as PDFs or desktop publishing files can be sent directly to the digital printing press to print on paper, photo paper, canvas, fabric, synthetics, cardstock, and other substrates. Any advertising done outdoors that publicizes your business’s products and services. Types of outdoor advertising include billboards, bus benches, interiors and exteriors of buses, taxis and business vehicles, and signage posted on the exterior of your own brick-and-mortar location.
