Facts About Thermography Powder And The Tips In Using It

By Dorothy Reynolds


In printing stationery or greeting cards, the maker wants them to have a glossy and smooth finish. This is made possible by an ink that is raised. Nowadays, there is a process followed by designers in enhancing not just greeting cards but also the paper bag, brochures, wrapping papers, packaging, and the like.

A principle of such process is simple. The designers make use of a thermography powder which will be applied to a surface of a printed material. The remaining powders, which is said to have a power that adheres to an ink which was not dried yet, are removed through suction, shaking, or vibration.

A conveyor is where the material with powders in it is upwardly faced. With its heater, this will provide a certain level of heat that could create an impact on the overall design. This simply implies that it dries the inked design and letters little by little until it achieves a desired effect.

This, too, comes in varying ingredients like gold or bronze shade and even glitters and silver. While it is still wet, you can assure that the inked parts will have adhered with powdered grains, which later on will permanently bound with it as melting occurs. In that instance, the powder itself will adapt to the colors or shades of a wet and inked part.

As a result, a suitable metal color has dominated. It is said to possess a characteristic which is similar to the effects of embossing. When this is heated, a glossy or shiny surface, which is raised, is formed due to the slight swell and fuse caused by the heat itself.

The preceding paragraphs have already given you an idea of what this creation could do and what is its nature and function. However, this entails certain factors that you have to consider before using such as a design of your artwork and medium or material. These will be explained in the next paragraphs. Those factors are generally classified into two aspects.

Generally, you can use any kind of paper with varying thickness and texture. However, if you want to achieve the best result, it is preferable to use one with a smooth surface. If you want to achieve that ragged appearance and a twist on your artwork, you can apply the powder on a textured or grained paper. But consistent reproduction on other papers of the same type will seem to be more difficult more than you will ever imagine.

Using one with loosed fibers is highly discouraged as its surface could occlude the powder grains. While the papers or stationery that are gummed are said to be thermographed, they should still be tested. This should be done to ensure that its gum will not be destroyed in the heating process. As for stationary and envelopes, it is done so that the grains cannot get inside them.

Facilitating the application of a certain degree of heat. As written earlier, you can adjust the heat. Special and massive to the heater and its conveyor. This knows no rules but merely factors like thickness, material, and texture of the paper. The coarseness of powders should be considered. Test the sample until you achieve the suitable level of heat.
