A thermal copier or thermocopier (used as a Tattoo transfer copier) is a kind of photocopier based on the effect of heat. The original sheet feeds in conjunction with the "thermo-sensitive" paper, generating a copy on its specially treated surface. The black parts on the original sheet, once scanned, make the copier activate the heating elements that produce some chemical reactions on the "thermo-sensitive" copy paper that darkens its surface.[1] After the process, a stable black-and-white image is obtained on the cooled film or paper.[2]
There are several types of thermal printers, among them and marketed at present time as Tattoo transfer copiers, there are two main types made by different manufactures: Thermo-head type and Heat lamp type
The black parts on the original sheet, once scanned, make the copier activate the heating elements that produce some chemical reactions on the "thermo-sensitive" copy paper that darkens its surface
Process: A special "thermo-sensitive" paper is fed into the copier at the same time but in indirect contact to the original. The thermo-sensitive paper is actually feed between the thermal head and the platen. The copier, while scanning the original, sends an electric current to some selected heating elements of the thermal head, which generate heat. The heated elements correspond to the black areas of the original and, being pressed against the copy paper, make the areas they touch on the "thermo-sensitive" substrate, to become darker.
Is a copying machine (in a drawer format) with a lamp as a heat source inside. An original sheet is exposed to the before said heat source in conjunction with future copy paper generating a copy on its specially treated surface. Is a kind of photocopy based on the effect of heat - When the black parts of the heat-sensitive paper generate some type of chemical reaction.[1] The heat lamp makes indirect revealing. After cooling the film or paper, a stable black-and-white image is obtained.[2]
Process: A special "heat sensitized" paper is fed into the copier in direct contact to the original. There is a strong lamp within the machine that heats both original and the "heat sensitized" copy paper. Due to its absorption of heat strokes of black colour areas in the original are hotter than the white areas which reflect light and do not become so hot. These black areas of the original being hot and pressed against the copy paper, make areas with "heat-sensitive" substrate in contact with them to become darker.
