What is Thermography?
-Commonly known as poor man's engraving, thermography produces raised printing similar in appearance to engraving but uses a different process. In thermography a special powder is added to the ink that is used for printing. The printed piece is heated and the powder and ink mixture dries to forma raised effect on the paper. This process is also known as offest thermography and raised printing.
-Thermopgraphy is sucessful when the powdered resins are applied to a printed surface on which the printing ink is still wet. This enables the powder to stick to the printed areas. Any powder on non-image areas, and any excess powder on the image areas is suctioned off before the heating takes place. Heat is then procduced with an electric element; which are placed in a tunnel or oven. When the heating process is complete, the sheet is cooled and the melted powder hardens to produce the raised affect.
