Example of thermographic printing. The uneven quality of the text is a result of the process and easily differentiates thermographic printing from engraving Thermographic printing refers to two types of printing , both of which rely on heat to create the letters or images on a sheet of paper.
Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements. The coating turns black in the areas where it is heated, producing an image.
[2] [3] It was a form of thermographic printing and an example of a dry silver process. [4] It was a significant advance as no chemicals were required, other than those contained in the copy paper itself. A thin sheet of heat sensitive copy paper was placed on the original document to be copied, and exposed to infrared energy. Wherever the ...
A receipt printed on thermal paper. A heat source near the paper will color the paper. Paper roll for thermal fax machine. Thermal paper (often supplied in roll form, and sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color locally when exposed to heat.
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
Thermographic printing is a process that involves several stages but can be implemented in a low-cost manufacturing process. The process involves printing the desired designs or text with an ink that remains wet, rather than drying on contact with the paper. The paper is then dusted with a powdered polymer that adheres to the ink.
Hot stamping or foil stamping is a printing method of relief printing in which pre-dried ink or foils are transferred to a surface at high temperatures. The method has diversified since its rise to prominence in the 19th century to include a variety of processes.
Thermal copier Pentacon PENTACOP 110 in a GDR Museum in Dresden. A thermal copier or thermocopier (used as a Tattoo transfer copier) is a kind of photocopi er 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.
