Capstan driven virtual internal drum imagesetter |
摘要 |
A virtual-drum capstan-driven device for outputting images from electronic files onto paper, film or plate material has increased output speed and reduced cost compared to an internal drum device. A capstan drive moves web type image recording media through a curved media platen having an upper curved surface and a lower curved surface which form the media into a virtual drum. The optical system has a rotating reflective spinner at the center of curvature of the virtual drum to scan modulated image date across media while being continuously driven. A tensioning mechanism maintains the media in a taught configuration and works in cooperation with the capstan drive to accurately control the motion of the media during imaging.
