Computer-to-plate (CTP or C2P) is an imaging technology which helps to transfer a digital image – generated in a computer – directly to a printing plate. Before CTP, the technology used was computer-to-film (CTF), where the image output was passed to a photographic film, and the output film was then used to make the printing plate. CTP lowers costs and shortens the amount of time needed to get a job on the press.
