Opting for CTP

Moving-target technology

There are literally dozens of approaches to computerized platemaking. For offset, a debate rages between thermal systems and visible light systems. Thermal technology features plate materials sensitive to heat rather than light, and which can be operated in daylight conditions. The laser must deliver a "threshold" energy level to the plate in order to expose a latent image. Due to this "threshold principle," the images on the plate are an exact replica of the energy delivered—and do not allow for "spreading" or render "unsharp" edges.
