CTP platemaking machines generally divided into inside drum, the drum type, plate type, curve type four major categories. In the four types at present, the most use is the internal drum and the drum; The performance with most high-grade CTP platemaking machines are the drum type.

 CTP technology concludes thermal imaging technology and light sensitive imaging technology, thermal imaging technology is the most widely used and with the most stable performance. At present, the most advanced, the most mature CTP platemaking machines thermal imaging technology is "square spot" thermal imaging technology rolled out by kodak .

Hangzhou Dongcheng Information Equipment corporation owns remote online control system.Engineers of the manufacture needn’t to arrive on the spot, easily provide “soft service” technical support.
