Method of loading metal printing plates on a vacuum drum
摘要:
Metal printing plates can be loaded onto a drum and held in place by vacuum alone if flat plates are given a permanent curl by a set of four rollers. Same rollers cancel out the curl when plate is unloaded from drum. The invention is useful for Computer-to-Plate and Computer-to-Press systems.
