Thermography is an examples of infrared image resolution science. Thermographic cameras detect radiation inside the infrared range of the electromagnetic spectrum and produce images of their radiation, called thermograms. Since infrared rays is emitted by means of all objects over absolute zero using the black body rays law, thermography can help to see one’s natural environment with or with out visible illumination. Thermography is a printing process the place that the ink is raised for the sheet. It was originally manufactured to simulate engraving at lesser cost. The procedure is done which has normal offset press and also “thermo” unit is mounted on the end of the press or duplicator.
