Thermographic Printing – Due to the high cost of the process and expertise required for engraving, many consumers opt for thermographic printing. Some describe thermography as “imitation engraving” or the “poor man’s engraving”. Since the design is not pushed from behind and there are no metal plates used like engraving, it is a less expensive process to produce.

Thermographic printing processes results in a similarly raised print surface with almost a shiny orange peel effect. This process also involves several stages. Ink is applied to the desired designs or text and remains wet, rather than drying on contact with the paper. The paper is then dusted with a powdered polymer that adheres to the ink. The paper is vacuumed or shaken (mechanically or by hand), to remove the excess powder before being heated. The wet ink and polymer bond and dry; resulting in a raised print surface. The look is similar to an embossed process (which will explored later). There is a wide range of colours available and other effects such as glitter, fluorescent or even full-colour thermography.

You can combine thermographic printing with regular offset, lithography or letter press. All these other methods will be addressed as well. However it cannot usually be used in combination with foiling because both processes require a heated application. The same principle would apply to only using thermographic printing on one side of the paper. Thermography also does not do well on fold lines or when it is cut because the raised ink tends to break apart under those conditions. It is also not a good idea to try and pass thermography through photocopiers or laser printers because these machines will heat the raised ink as well.
