Thermographic Printing

In thermographic printing, the raised image or type is obtained by spreading powdered resin on the wet ink, after which heat fusing is done on the paper sheet. Different types of powdered resins are used in thermographic printing. The printing can be accomplished in manual or automated fashion and can also be combined with specific types of finishing. Unlike engraving or die-stamping, the finer details of logotypes or typography are shown in a thermographic print. Also, since thermographic printing involves a heat-set process and printing is raised, the printing is not recommended for all laser printers or copiers, as they need to operate at higher temperatures.

Thermographic printing is less costly than engraving and thus provides an inexpensive visual appeal to printing wherever needed. It is also more natural looking compared to other methods of engraving and also has an excellent definition.

Thermographic printing can be expensive, and the sheets are usually costly. Thermographic printing can be applied to only one side of the print. There is a limitation on the font size used, which is recommended not to be smaller than 6 points. Shrinkage of image is usual and can sometimes cause paper distortion; therefore, it is recommended to avoid large solid printed areas. Fine typefaces or heavy solids are often not recommended. Heat can also damage the raised print, making it lose its luster and rise.
