What is the heat transmitted?

Thanks to the digital display and printing technology, anyone can now own a T -shirt, a cup of coffee or a hat that says anything he wants. Lithography with screen printing and compensation, primary alternatives to heat transmitted, are laborious processes, chaotic with ink and tanned chemicals. However, creating heat transfer is relatively tidy and fast, accessible to all with a computer and printer and leaves only paper like waste.

There are two ways to print a portable heat. Both require inks, heat source and receptive surface or substrate, but differ in their details. One of them is topical transmission , which places ink on the fabric. The second, called sublimation printing , makes the ink part of the fabric by a chemical reaction.

iron applied to a T -shirt is the current therint to its simplest. Iron is digital oBraz printed on special transmission paper, which is covered with a clear film. The iron applied to the back of the transmission paper softens the clean film so that it holds the shirt together with the picture. In commercial setting, a machine called the heat transfer press is used instead of iron. The heat transfer press develops higher heat and larger, more evenly distributed pressure. Printing can be either valid, which consists of a flat bed with a suspended lid or a roller. Using either creates a closer bond between textile and film than iron. Nevertheless, inks that form the image reference to the fibers of the substance only on the surface, and over time there will be some peeling and loss of ink.

The

sublimation printing works using specific inks that become part of the fabric when exposed to pressure and heat - inks are in . The word sublimation come from the Latin meaning of at the threshold of indicating what goes beyond physical or palpable. Sublimation is chemicalThe reaction in which the substance transforms from the solid to gas and skips the liquid condition. In prints transmitted by the heat produced by sublimation inks, the substrate and transmission paper pass through the press. Under an intense heat of about 400 degrees Fahrenheit (about 204 degrees Celsius), inks sublimate and penetrate the substrate as gas.

Not all substrates work with sublimation. Because the inks used in this way create a thermally transmitted printing largely by unpredictable water, they create links with similarly materials insoluble in water such as polyester and other synthetics. However, objects that are not made of synthetic materials such as ceramic coffee mugs can receive images transferred by sublimation if they are first covered with a polymer film. However, such things require specially designed presses and generally cannot be achieved with existing tools at home.
