Let's find out what material the thermal CTP plate is made of. The heat-sensitive ctp plate is thermally decomposed/polymerized and imaged by the photosensitive resin in the photosensitive material under the irradiation of infrared light. The light source of the heat-sensitive plate is infrared light of about 830nm, and infrared light is accompanied by heat.
Thermosensitive imaging material is a concept that covers a wide range. The well-known thermosensitive recording paper has long been used in computers, fax machines, and thermal printers supporting various instruments and meters to record the output—graphic information. The basic principle of imaging of thermosensitive recording paper is that thermosensitive paper undergoes thermal-induced color development or discoloration under a hot needle's action so that text or images are recorded on thermal recording paper.
