CTP plate has several meanings: computer to plate, computer to press, computer to paper/print. Here we refer to computer to plate. It is an imaging technology used in modern printing processes. In this technology, an image created in a Desktop Publishing (DTP) application is output directly to a printing plate.
There are three types: photopolymer plates, siverhalogen plates and thermal CTP plate. Thermal CTP platemaking technology is currently the most mature, stable, and effective platemaking technology.
The PS plate and CTP plate has been developed in China for over one decade. Haomei Aluminum has comprehensive range of aluminum plates for making PS plate and CTP plate.
