The so-called CTP plate making machine is computer to plate,which is a prepress equipment directly made by computer.CTP plate making is to adopt digital workflow,directly convert works and images into numbers,and directly generate printing plates,eliminating the material of film,the process of manual composition,semi-automatic or full-automatic plate printing process.Compared with traditional plate making,CTP plate making is characterized by the elimination of film.
CTP plate making machines are generally divided into four categories:inner drum type,outer drum type,flat plate type and curve type.Among these four types,the inner drum and outer drum are the most used at present;Among them,the high-end CTP plate making machines with better performance all use the external drum type.
CTP plate making techology has thermal imaging technology.At present,photosensitive imaging technology is the most widely used and the most stable technology.
