Definition - What does Thermographic Printing mean?
Techopedia explains Thermographic Printing
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.
